Re: Communication (in-vm) between webapps

[Jim Pinkham]

My first thought would be ehcache all the stuff in front end with a
reasonable expiration period (hours maybe), and then expose a very simple
JMX interface to manually reset the cache without bouncing the entire
app.  No need to send much data over JMX other than just a simple 'refresh
all caches' command. Pretty simple, but gives you a lot of options.

Good luck

DateTextField maxlength idea

[Jim Pinkham]

I have a simple data entry form with a date/time field.

My end users (web newbies) have found another interesting way to confound
the most clear and straightforward instruction I can devise regarding it's
(obvious?) use.

I watched an end user type an entire time into the hour component without
tabbing over to the minute.

So, I'd like to suggest a minor change to
extensions.yui.calendar.DateTimeField.html to add the maxlength="2" to the
current size="2" on the hour/min input controls.

I think it might be a simple way to give earlier feedback  (I've found it
unwise to rely on instructions like "Please enter dates and times like
this..." ).

I know I could accomplish this for my own instances, perhaps with a copy of
this modified html in a spot higher in the classpath, or maybe an attribute
modifier someplace..., but then I thought what is the downside of making it
the default?   Sure, it would impact a lot of code, but unless some locale
I don't know of has 3 digit minutes, I don't think in a negative way --- I
was suprised to find no other similar past discussion; perhaps there is
some obvious reason this isn't a good idea?   I can't be the first one to
think of this, can I?

Cheers,
Jim

In case all that's not clear, here's what I mean in code:

MyPage.html
MM/DD/ [picker] HH MM [amPM]

MyPage.java
add(new DateTimeField("eventOn"));

Re: wicket + jasper reports

[Jim Pinkham]

Got it - found another hint about DownloadLink that led me to this solution:

@Override
public void onSubmit() {
ReportResource resource = new PdfReportResource(getReportName(),
getParamsModel());
getRequestCycle().scheduleRequestHandlerAfterCurrent(
new ResourceRequestHandler(resource, null));
}

So simple, but it took some digging to find so hope this helps someone else.

Re: wicket + jasper reports

[Jim Pinkham]

OK, I've almost got it - thanks for the example.

It comes down to either using a ResourceLink which serves up the pdf
with no complaints, but despite being attached to a submit button, the form
doesn't seem to have been submitted; the parameters don't reflect any user
input

or, I can solve that if I use a Button instead, and copy this code from
ResourceLink.onResourceRequested into the Button's onSubmit()...

Attributes a = new Attributes(RequestCycle.get().getRequest(),
RequestCycle.get()
.getResponse(), null);
resource.respond(a);

But if I do that, it works but then I get "Header was already written to
response!" as mentioned earlier.

I also tried making my own MyResourceLink (I would rather have extended
ResourceLink but I had to go all the way back to Link because ResourceLink's
onResourceRequested is final) and I put a call to
ParamsForm.this.process(this); then super.onResourceRequested(), and that
stopped the error but still didn't submit the form.

Has anyone found a way to get the best of both?  I found SubmitLink, but I
guess I need some way to 'mix that in', or decorate the ResourceLink with a
submit first... not sure how to do that..  (ResourceLink already implements
IFormSubmittingComponent, but I guess that's not enough)

(I tried calling inputField.getConvertedInput() like I might do from a
validator but that just returns null, which is what leads me to believe the
form hasn't been submitted)

Thanks,
-- Jim.

Re: wicket + jasper reports

[Jim Pinkham]

Paul,

I am doing something very similar - I'd be interested to know more about how
you got this working - here is what I've got that works for now, but I'm not
real happy with it:

In my report forms, I have buttons like this:  (details about params omitted
- nothing fancy there)

add(new MyReportResourceButton("pdf", new
ReportResource("MyReport", new PdfResourceHandler()), paramsModel));
add(new MyReportResourceButton("xls", new
ReportResource("MyReport", new XlsResourceHandler()), paramsModel));

(So it will load MyReport.jasper that was compiled and put into resources
folder by maven plugin during build)

MyReportResourceButton has this:
@Override
public final void onResourceRequested() {
Map params = paramsModel.getObject();
resource.setReportParameters(params);
super.onResourceRequested();
}

and it's superclass MyResourceButton has this:
@Override
public void onSubmit() {
onResourceRequested();
}

/**
 * @see org.apache.wicket.IResourceListener#onResourceRequested()
 */
public void onResourceRequested()
{
Attributes a = new Attributes(RequestCycle.get().getRequest(),
RequestCycle.get()
.getResponse(), null);
resource.respond(a);
}


At runtime, it basically works, however, it gives me this annoying message
in my logs multiple times per report request after the report has been
served and it appears to be trying to just stay on the same page:

2011-10-13 15:22:42,381 [http-80-12] ERROR

Could you tell me if there is some way this differs from how you (or your
contractor) are doing it?

Re: CouldNotLockPageException using localized RequestMapper URLs

[Jim Pinkham]

Thanks - I did that, and found the culprit was a file upload (that part was
okay) which fed into an piece of image resizing code:

Graphics2D graphics2D = rescaledImage.createGraphics();

which the stack trace showed was waiting forever on some other AWT init
thread.

So I just kicked it to the curb and used another image scaling library from
http://code.google.com/p/java-image-scaling/  and the problem has gone
away!   So not wicket related at all.

In retrospect, I can't think of a more informative way the framework could
have helped me discover this  - my breakthru came from the old
tried-and-true method of finding a way to reproduce the issue (of course
that is the hard part - seems like it took forever, trying to explore all
the functions in my system) and then when it finally happened, doing a
thread dump.

Anyway, situation resolved!  Back to happy wicket coding...

Re: ResourceReference.getResource() returns NULL ?

[Jim Pinkham]

Search for "Dynamically loading image" for good examples of how to do this.

Basically, you do not put the image data directly into HTML.  Instead, you
make your page.html  with some table perhaps, and a series of links to your
images.  So you would need one method to list the ids of your images to put
as a parameters into your links.   Then, you will 'mount' the resource in
your application class at app init time, which will allow your app to serve
up the image data for each  tag.

Good luck
Jim

Re: Copying PageMaps from one session to another

[Jim Pinkham]

To expand on Josh's suggestion,

In your Login link (probably on an abstract page you inherit for other
app pages) you would have an onClick that doesn't just
setResponsePage(YourLoginPage.class), but instead throws the
Restart...exception.  That way, when the login completes, it should
come back to the page the login link was pressed on.

Internal Error shows up in Google Cache

[Jim Pinkham]

I mentioned a few weeks ago I had some page locking issues.

I turned on logging and overrode the PageAccessSynchronizer to log and
swallow the page lock exception (it still has the timeout wait, so
it's not totally disabled), but of course it hasn't happened since, so
I still haven't found the root cause other than some heavier usage
(1500 page loads/day is busy for me - go ahead, laugh ;)

... but now I just noticed my search results in Google are showing
these Internal Error page in search results!

Yikes - Bad news!

So, my band-aid fix is this:

    protected final class MyInternalErrorPage extends InternalErrorPage {
        private static final long serialVersionUID = 1L;

        @Override
        public void renderHead(IHeaderResponse response) {
            response.renderString("");
        }
    }

and in my application init():
        
getApplicationSettings().setInternalErrorPage(MyInternalErrorPage.class);

I'm thinking this might be a good default for this page?

Of course we don't want internal errors in the first place, but if
they do happen (to a robot), no reason to literally advertise the
fact, right?  Seems like a drag on the brand name to some degree..

On a side note, does anyone know how to tell google to get rid of a
cached search result like this, or am I stuck waiting for the next
robot to come along?

To see what I mean, google for "Together Auction" (2nd result, crawled
May 21, still here June 3):

Catalog - Internal Error

Internal error. Return to home page.
togetherauction.com/firstuu/catalog - Cached


OK, back to the page locking issues - the only unusual thing I'm doing
is that I have my app deployed at my domain root with suffixes for
each of my clients so they each appear to have their own version of
the web app served from a common ROOT.war.   So my URLs are like this:

mydonamin.com/clientname/restOfURL.   This is done via a
ClientFirstRootRequestMapper extends AbstractComponentMapper
(source if anyone is interested: http://pastebin.com/Zxp561JK )

For some reason, this was working great in 1.5 M3 but since I've
upgraded to RC3, I'm seeing ;jsessionid= on all my URLs now - not sure
if that is related.

I mention the RequestMapper because I wonder if this might result in
two different clients using same page class with instance keys that
might not be unique and thus have locking conflict from that ?

Thanks for any insights any of you wiser wicket ones might have to share.

Re: Help I need to understand page locking

[Jim Pinkham]

Thanks, good tip.  I'll do that, and I'm also going to send in a replacement
copy for PageAccessSynchronizer that still has the one minute delay, but
then if it fails, it forces the lock anyway and swallows the exception -
hopefully that will solve my lock ups until I can find the cause:

locks.put(pageId, lock);  // force it - temporary fix only
logger.error("failed to acquire lock would have thrown: ",
/*throw*/ new CouldNotLockPageException(pageId,
thread.getName(), timeout));


Thanks,
-- Jim.

Help I need to understand page locking

[Jim Pinkham]

I'm using wicket 1.5 RC3 and just started getting some total system lockups
recently in prod that I can't understand.

Once it gets into this state, the only remedy is to restart tomcat.
Unfortunately, I haven't yet figured out how to reproduce this, so meanwhile
I thought I'd ask if someone could please help me understand how page
locking works in general and what I should be looking for.

When I think of locking I usually think of threading, so not sure if it
matters, but I do start one a thread for email sending with the Application
thread local set for it also (because I manage data sources thru the app so
it was easier that way).  I could try refactoring that, but without a
reproducable test case, it's just a guess at this point.  My other plan
would be to revert to some older wicket version, but again, just a guess.

Here is the stack trace; nothing unusual precedes it.  (This is just a user
trying to visit the home page).  The only thing I notice is that these
issues all seem to be using the PageParameter version of the page
constructor.

tomcat stuff omitted..

Re: Last Page visited

[Jim Pinkham]

Well, most browsers already have back button, so I'm not sure why you would
want to re-implement that, but assuming you do, here's one way to do what I
think Martin is suggesting by "pass a page reference":

abstract class AbstractBase extends WebPage {
 PageReference priorPage;

 public AbstractBase(PageReference priorPage) {
   this.priorPage = priorPage;
 }
 public PageReference getPriorPage() { return priorPage; }
}

class PageThatNeedsABackButton extends AbstractBase {
 public AnyOtherPage() {
super(getPage());// you need to tell it where 'back' is as
you make each page

add(new Link("id") {
  public void onClick() {
   setResponsePage(getPriorPage());// then later you can
go there
  }
});
 }

Hope that makes sense.  Not a great idea, but hope it helps to experiment
and learn.

-- Jim.

[Vote] New Wicket Version Numbering

[Jim Pinkham]

I've had a hard time lately trying to get corporate acceptance of the Wicket
framework.

In fact, our company looked at this comparison of java frameworks:

http://en.wikipedia.org/wiki/Comparison_of_web_application_frameworks

  *Project* *Current Stable Version*  Apache Click  2.2.0   Apache Cocoon
2.2.0   Apache Struts  2.2.1.1   Apache Tapestry  5.2.4   Apache Wicket
1.4.15   AppFuse  2.0.2   Aranea  1.0.10   Eclipse RAP  1.2.0   FormEngine
1.7.1   Google Web Toolkit  2.2.0   Hamlets  1.6  IceFaces  2  ItsNat
1  JavaServer
Faces  2  JBoss Seam  2.2.0 GA   Jspx-bay  1.1.0   JVx WebUI  0.8  ManyDesigns
Portofino  3.1.10   OpenLaszlo  4.1  OpenXava  4.0.1   Oracle ADF  11.1.1.4
Play  1.1.1   RIFE  1.6.2   Shale  1.0.4   Sling  5  SmartClient  8  Spring
3.0.5   Stripes  1.5.4   Telosys  1.1.1   ThinWire  1.2  Vaadin(IT Mill
Toolkit)  6.5.1   Wavemaker  6.1.10   WebObjects  5.4.3   WebWork  2.2.6
ZK  5.0.5   ztemplates  0.9.9.6

The powers that be decided to pick Smart Client over Apache Wicket because
they have the highest version number.

So, I think the time is right to move straight to the front of the pack and
release version 10.0.

Who's with me?

Re: Wicket in Action: problem with redirection

[Jim Pinkham]

Martin,

Thanks, no I hadn't seen that... but now I think this is just because I
over-simplified the quickstart - it still doesn't explain why it was working
properly up thru 1.5-M3   (using examples from wicket-auth-roles to have
login link hander throw this restart exception, so if that's not a bug, I
must be missing something else...

So I've got my kludge fix for now, and it works in both the quickstart and
my own app, so it'll get me along for a while..  I'm happy to assist further
but feeling a bit past my level of experience.

Thanks,
-- Jim.

Re: [1.5] Two formcomponents editing the same model?

[Jim Pinkham]

Hmm... If I were designing a component like this (and for some reason didn't
like the ones out there like datepicker that already do this)  I'd make a
new component that extends panel with 2 separate child controls, each with
their own date models.  Then use a top level model  getter / setter that
just pushes/pulls the 2 child dates independently using the
java.util.Calendar's fields independently.

Hope that helps,
-- Jim.

Re: Wicket in Action: problem with redirection

[Jim Pinkham]

FYI - rc2 still has this problem.  It works OK on a  BookmarkablePageLink to
a page that implement IAuthorizationStrategy, but not on the new
Link on a panel on my home page.  After login is complete, the
link is hidden and replaced with a logout link, so the user gets an
AccessDenied page after login as they try to 'restart the response' to the
(wrong) onClick handler url for the now-invisible login link.

Not sure when I'll get to making quickstart, but I thought I'd give at least
this brief info for now.

Re: Wicket in Action: problem with redirection

[Jim Pinkham]

I think I've got the same situation happening.

It's a login link on my home page, whose onClick
uses the usual:
throw new RestartResponseAtInterceptPageException(
AuctionApplication.get().getSignInPageClass());

I've stepped thru this a bit, and I find a problematic point in:
RestartResponseAtInterceptPageException.InterceptData.set() where it
captures what I think is supposed to be the home page url, which it is
saving as follows:
...
data.originalUrl = request.getOriginalUrl();

However, in my debugger, this is instead the Url of the link:

http://localhost:8080/myapp/wicket/page?0-1.ILinkListener-userPanel-signIn

If I manually change it in the debugger to just my home page Url, it seems
to work fine.

This was working last for me in 1.5-M3, and now in 1.5-RC1 it appears to
have broken.

Hope this helps narrow the search...

Thanks,
-- Jim.

Re: [VOTE] WICKET-3218 - Component#onInitialize is broken for Pages

[Jim Pinkham]

Interesting problem.

It helped me visualize the issue when I tried to suggest:

myPage() {
   add(new Thing(this,...)); // 'this' doesn't exist yet
}

I think building component hierarchy from constructors feels natural and
it's going to be a hard sell to change to support this use case where some
components might need to know their parents.

I thought I was keeping pretty much up-to-speed on 1.5 changes, but I'm kind
of surprised this is the first I'm noticing this fairly substantial API
change.

Sorry if something like this has already been shot down - I didn't look -
but just off the top of my head, seems like there could be a way to have the
framework (as it is about to add a page to it's map or at some other
convenient early point) go back down thru the hierarchy and visit all the
components to offer them a parent reference?   Maybe guarantee it would
happen before the first onBeforeRender or something like that?

Then, we could let these visitors 'vote' on when the hierarchy is finished
changing -  (i.e. components could use this information to make additional
changes to the hierarchy) by returning a value.   Perhaps call this new
component visitor something like int onParentChanged(Component parent) -
return flags that would let the framework interrupt and restart, repeat
after finish, or just continue visiting (or maybe just return boolean repeat
flag).

How to make DateTimeField default to PM

[Jim Pinkham]

I wanted to have my DateTimeField (That's the wicket-extensions component
with a date text field, button to open calendar, and hours/minutes fields
with optional AM_PM choice) default to PM instead of AM for new dates
because I noticed most dates in this part of my app are evening dates.

I came up with this; maybe it helps someone, or let me know if you have a
better way:

FormComponent dateField = new DateTimeField("eventOn") {
private static final long serialVersionUID = 1L;

// amOrPmChoice is final, so we have a little kludge to
default new item's eventOn date to PM
// TODO: find a less clever way
@Override
protected void onBeforeRender() {
Date d = (Date)getDefaultModelObject();
if (d == null) { // user hasn't entered a date (yet)
Calendar c = Calendar.getInstance();
c.set(Calendar.HOUR_OF_DAY, 18);  // anything after
noon would work
IModel dm = (IModel) getDefaultModel();
dm.setObject(c.getTime());
super.onBeforeRender();   // initializes
amOrPmChoice as side-effect
dm.setObject(null);
}
super.onBeforeRender();
}

@Override
protected DateTextField newDateTextField(final String id,
final PropertyModel dateFieldModel) {
return DateTextField.forDatePattern(id, dateFieldModel,
"MM/dd/");
}
};
Cheers,
-- Jim.

Re: Free wicket from component hierarchy hell

[Jim Pinkham]

I'm not a committer, just a normal 1.5 user concerned about bloat.

For what it's worth, I took a few minutes to actually look at the change
(MarkupContainer as you'd expect) and I can see that if you don't use the
new queue methods, the only a memory overhead is the *static* QUEUE (nothing
extra per component!) so I appreciate that performance-wise anyway, it's a
low impact feature you can ignore without penalty.

I'm not thrilled about the conceptual impact of adding a new concern to an
already large class, but the implementation looks quite nice actually, so my
first concern that it might break existing behavior is satisfied.

I still don't think it's necessary, and wonder if it might actually be
counter-productive to have more than one way to learn for new adopters.  If
it goes forward, I don't suppose there's much precedent for taking something
back out, is there?

What a difficult discussion to have over email - I'm in the -1 camp on this
overall, but I think I do appreciate the admirable motive to innovate, so I
hope the committers will give this serious consideration and then chuck it
in the bin where it ...  no, just kidding,  ;)  and then make a fair
decision.

Thanks,
--Jim Pinkham.

Re: JasperReport viewing options for wicket 1.5

[Jim Pinkham]

... and to follow up briefly - I got past the class not found by adding:
 

org.apache.poi
poi
3.2-FINAL


(Although even then, mvn eclipse:eclipse didn't add it - I had to add it
myself to the classpath! - perhaps because it's declared as "optional" in
the projects's pom.xml ?  wierd.)

So now I can click on my link and download an XLS, but then I get this
lovely message:

Excel found unreadable content in 'report1xls'.  Do you want to recover the
contents...  OK sure... then:
'Damage to the file was so extensive that repairs were not possible.
...etc'.

The resulting workbook that finally opens looks like it's ok at first, then
all messed up starting a few pages down where a string value contains an
ampersand  (It's possible the data has some HTML like  &).

To say that I'm out of my element here is an understatement.

If I don't get any better ideas, I'll go with this hack (notice I switch to
using the HTML exporter):

private static IJRResourceHandler fixXls(IJRResourceHandler handler) {
// kludge for xls
if (handler instanceof XlsResourceHandler) {
return new XlsResourceHandler() {
private static final long serialVersionUID = 1L;
@Override
public JRAbstractExporter newExporter()
{
JRAbstractExporter exporterXLS = new JRHtmlExporter();

exporterXLS.setParameter(JRXlsAbstractExporterParameter.IS_ONE_PAGE_PER_SHEET,
Boolean.TRUE);

exporterXLS.setParameter(JRXlsAbstractExporterParameter.IS_DETECT_CELL_TYPE,
Boolean.TRUE);

exporterXLS.setParameter(JRXlsAbstractExporterParameter.IS_WHITE_PAGE_BACKGROUND,
Boolean.TRUE);

exporterXLS.setParameter(JRXlsAbstractExporterParameter.IS_REMOVE_EMPTY_SPACE_BETWEEN_ROWS,
Boolean.TRUE);
return exporterXLS;
}
};
}
return handler;
}

But it makes all kinds of ugly dead image links every other row and column
around the data.  Yuck.

Any other jasper users want to share any tips here?

Thanks,
-- Jim.

Re: JasperReport viewing options for wicket 1.5

[Jim Pinkham]

Well, I seem to be making good progress, but still not 100% there.

I got "git" and did a clone of wicketstuff and built jasperreports and added
it's target\jar to my local repo.
I only had to change the core's pom.xml to refer to the 1.5-M3 version I'm
using instead of 1.5-SNAPSHOT.

So far so good - pdf reports work fine (hooray) but now XLS is giving me
this:

NoClassDefFoundError: org/apache/poi/hssf/usermodel/HSSFCellStyle

Also, while I'm at it, maybe this saves someone else a bit of effort -

I had to add a log4j dependency to the jasperreports-maven-plugin as
described in the final post here:
http://jasperforge.org/plugins/espforum/view.php?group_id=102&forumid=103&topicid=63750

And here's how I'm using it:

public class ReportResource extends JRConcreteResource {

public ReportResource(final String report, final IJRResourceHandler handler,
final Map params) {
super(new File(ReportResource.class.getClassLoader()
.getResource(report+".jasper").getFile()), fixXls(handler));

setReportParameters(params);
setFileName(report+handler.getExtension());
setConnectionProvider(new IDatabaseConnectionProvider() {
private static final long serialVersionUID = 1L;
public Connection get() {
try {
// If I hold on to conn reference here I get
serializable problems
return
MyApplication.get().getConnectionForCurrentDatabase();
} catch (SQLException e) {
return null;
}
}
public void release() {}   // should I be doing conn.close?
});
}
}

And then here's how I use it:
add(new ResourceLink("testPdf", new ReportResource("report1",
new PdfResourceHandler(), params)));
add(new ResourceLink("testXls", new ReportResource("report1",
new XlsResourceHandler(), params)));

So I think it's just a missing dependency someplace... anyone got a tip for
me? (ideally, how I can find it myself rather than mooch)

Any advice would be most welcome!

Thanks,
-- Jim.

Re: JasperReport viewing options for wicket 1.5

[Jim Pinkham]

Thanks - so glad to see it's been ported to 1.5; now, I need the jar.

Maven gives me:
Unable to find resource 'org.wicketstuff:jasperreports:pom:1.5-SNAPSHOT' in
repository public (http://public)
.. and then again for 2 repositories I tried adding: wicket-snaps, and
nonatype-nexus-snapshots at
http://wicketstuff.org/maven/repository
and
http://oss.sonatype.org/content/repositories/snapshots


Am I missing a new repository since the move to GIT ?  Everything else
(wicket, wicket-extensions, wicket-datetime, wicket-auth-roles,
mysql-connectory-java, commons-dbcp, spring, jasperreports, ehcache, jetty
...etc works OK.  ??

Perhaps someone who knows might be able to update this wiki page:

JasperReport viewing options for wicket 1.5

[Jim Pinkham]

I found this tantalizingly close msg:

http://www.mail-archive.com/users@wicket.apache.org/msg55375.html

Sounds like about what I'd need; except I've moved on to wicket 1.5.

I don't need any pagination or other bells & whistles - just a simple way to
deliver dynamically generated pdf reports.  (Although Excel ouput might be
nice too)

I think I'd do links with report name and other named parameters in the URL,
then have my app declare a shared resource mounted at \reports.

I was hoping someone has already done this and I could learn (or shamelessly
copy) from it.  ;)

I could not find any version of org.wicketstuff jasperreports > 1.4.x

I did find jasperreports-maven-plugin and so it's compiling .jrxml into
.jasper at build time just fine.

Could someone kindly point me in the right direction with a brief example
perhaps?

Thanks,
-- Jim.

RenderBodyOnly and email links

[Jim Pinkham]

Many may already have realized this, but for anyone who hasn't, I just came
across this elegant way to handle optional emails.
The user/admin stuff is just an example use-case, simplified to fit here.

// User's Statement page lists some items and who bought them...

AbstractLink myLink;

if (isAdminUser()) {
// admins can view the buyer's full info
myLink = new BookmarkablePageLink("buyer.link",
MemberPage.class, params)
} else {
// normal users get email links to each other instead
myLink = new ExternalLink("buyer.link", email);

// or if they don't have email, just show their name
myLink.setRenderBodyOnly(email.isBlank());// if they don't have
an email
}
myLink.add(new Label("buyer.name"));

Before I found this, I had two separate elements - the a link with it's span
name inside, and then another span name with only one or the other visible -
that was ugly.

Maybe this helps someone else

Re: PageParametersEncoder migrating from Hybrid

[Jim Pinkham]

Peter,

That worked great!

For mine, I added a test for even number of segments like so:
List segs = request.getUrl().getSegments();
if (segs.size()%2==1)
segs.add("0");  // maybe throw exception instead?

String[] named = segs.toArray(new String[segs.size()]);
Thanks again,
-- Jim.

PageParametersEncoder migrating from Hybrid

[Jim Pinkham]

In my 1.5-M3 app's init, I've got:

// this part works fine, just wanted to show where the  comes
from below...
getRootRequestMapperAsCompound().add(customHomeMapper);

getRootRequestMapperAsCompound().add(
new MountedMapper("/statement", StatementPage.class));

and my StatementPage URLs look like this:

http://localhost:8080//statement?id=3&p2=75

I need them to look like this:

http://localhost:8080//statement/id/3/p2/75

Looks like HybridURLCodingStrategy is out and PageParametersEncoder is it's
replacement... but no subclasses that do what I need.

Is there a 1.5 equivalent before I go write one, or is there another way?

BTW, the ability to have the custom home component mapper is the reason I'm
migrating - I'm so happy to have that feature!!
I just need a bit of help getting this into final form.

Thanks,
-- Jim.

maybe this authorization strategy helps someone

[Jim Pinkham]

I needed to authorize some pages not just by annotation but also based on
PageParameters.

I came up with this:

App.init()


((CompoundAuthorizationStrategy)getSecuritySettings().getAuthorizationStrategy())
.add(new RequiresRolesUnlessAdminAuthorizationStrategy(new
Roles("ADMIN")));

public interface IRequiresRole
{
Roles requiresRoles();
}

public class ProfilePage extends MyWebPage implements IRequiresRole
{
private String id;
public ProfilePage(PageParameters p) {
id = p.get("id").toString();
}
public Roles requiresRoles() {
return new Roles(id);   // I'm just using the id as a role for
testing but you can lookup your object and see what roles it needs here
}
}

And the fun one:

public class RequiresRolesUnlessAdminAuthorizationStrategy implements
IAuthorizationStrategy {

private Roles alwaysAllow;

public RequiresRolesUnlessAdminAuthorizationStrategy(Roles alwaysAllow)
{
this.alwaysAllow = alwaysAllow;
}

public boolean isActionAuthorized(Component component, Action action) {
if (component instanceof IRequiresRole)
{
Roles r = ((IRequiresRole) component).requiresRoles();
return AuthenticatedWebSession.get().isSignedIn() &&
(
AuthenticatedWebSession.get().getRoles().hasAllRoles(r)
||
(alwaysAllow != null &&
AuthenticatedWebSession.get().getRoles().hasAnyRole(alwaysAllow))
);
}
return true;
}

public  boolean
isInstantiationAuthorized(
Class componentClass) {
return true;
}
}

So if you are ADMIN you can do anything, otherwise you need whatever role
corresponds to object identified by the PageParameter id.

Am I re-inventing someone's wheel here, or does this sound good?

Thanks,
-- Jim.

Re: how to have one app at multiple root contexts

[Jim Pinkham]

Super - that works great!

I especially like how it won't have to be a PageParameter this way.  (At one
point I thought I'd have to do it that way).

You've saved me a lot of work!

Thanks again,

Re: how to have one app at multiple root contexts

[Jim Pinkham]

I've studied the example, but I'm still not seeing how to make it work at
the root.  I'm trying to get URLs like this

http://localhost:8080/-   container should render index.html
http://localhost:8080/foo  -  should render HomePage
http://localhost:8080/bar  -  should render HomePage
http://localhost:8080/foo/wicket/bookmarkable/com.example.OtherPage

which don't have the /localized prefix (the example uses /localized/en_US/)

So I tried replacing this:

getRootRequestMapperAsCompound().add(
new LocaleFirstMapper(new MountedMapper("/localized",
LocalizedPage.class)));

with this (because I don't have a prefix like "/localized")

getRootRequestMapperAsCompound().add(
new MyLocaleFirstMapper(getRootRequestMapper()));

but then it goes into a loop "delegating to the chain".

I feel like I'm missing something obvious...  not too proud to ask for a bit
more hand holding?

Thanks very much,
-- Jim.

how to have one app at multiple root contexts

[Jim Pinkham]

I've got a wicket 1.3 app I'm refactoring to add security and more scalable
'root contexts'.

I think may involve going to wicket 1.5 but I haven't found any actual
examples of this to study - seems like it would be a common need.

Right now, I have a dozen different maven profiles that crank out nearly
identical war files named for each profile (aka root-context aka clients).
I'll run out of memory soon with this approach so I'd really like to get
back to just a single war file to deploy at root context and somehow pull
the client names dynamically.

It would be OK to redeploy to add client mappings at app.init since there is
some db config for each new one anyway, although it would be best to have no
outage for other clients when new one is added

For the security, I found a great help
here.
Unfortunately, it doesn't work with Wicket 1.5.  Anyone working on that?  I
gave it a quick effort, but got stuck on the  WaspWebApplication's
newRequestCycle method which I just don't understand.  The best I could do
was get it all working with:
1.4.13
1.4.1   (and for this I had to
declare and download manually: swarm,wasp,hive,wicomsec)
6.1.25
2.0.4

I had thought to try spring-security's OpenID authentication so my users
could use their existing gmail or flickr or whatever ids and not have to
create a new one just for my sites... but now I'm thinking to keep it
simpler and just use wicket-auth-roles in order to use wicket 1.5.

Can anyone offer advice to help me make progress on either of these issues?

Thanks,
-- Jim.

learn from my security mistake with getString

[Jim Pinkham]

I was just looking around for my dunce cap after noticing this little gotcha
- and I thought of this forum instead to share my moment of
not-so-brilliance:

public LoginForm(final String id) {
... other stuff ...
add(new FormComponentFeedbackBorder("user.feedback").add(new
TextField("user").setRequired(true)));
passwordField = new PasswordTextField("password");
passwordField.setRequired(true);
add(new
FormComponentFeedbackBorder("password.feedback").add(passwordField));
}
protected void onSubmit() {
String password=getString("password").trim();
if (password.equalsIgnoreCase(getPassword())) {
((AuctionSession)getSession()).setAdmin(true);
((AuctionSession)getSession()).setUserName(getUser());
if (!continueToOriginalDestination())
setResponsePage(getApplication().getHomePage());
} else
passwordField.error("invalid user/password");
}
}

Pretty basic, I know.  Maybe you have a page like this in your Wicket app?


The mistake I wanted to share is that I'm using the same name for the
"password" wicket:id, and the string property in MyLoginPage.properties,
which just has a line that says password=super_secret_whatever.  (Actually,
it's ${profile.password} and I have different maven profiles for different
versions of the app, but that's another story).

Anyway, imagine my suprise when I accidentally left the password blank by
mistake - the required error message uses the same property and shows the
password to the wide world in the feedback message: 'super_secret_whatever'
is required.  Hah!(Yup, it's been in production for quite a while like
this...)

Just wanted to share that one with y'all - may all your mistakes be
entertaining and/or educational...
:)

Configuration Q re Maven Profiles and Start

[Jim Pinkham]

There must be something simple I'm missing - I'm fairly new to maven, but I
love the profile feature for different client versions of a hosted turnkey
app I'm working on.

So, I build multiple war files specifying each -PprofileName and rename the
WARs to the context root I want (usually same as the profile name) and
deploy them - everything works OK.  This lets me put references to
${profile.thisOrThat}
in various places - html files, Somepage.properties, even
applicationContext.xml and web.xml.

But I realized, I've now lost the handy ability to debug Start.java - of
course, it sees the plain version of these config setting, so it doesn't get
very far.  This is slowing me down on minor HTML tweaks, for example, that
used to be super-fast and easy cause now I'm back to the old fix, compile,
deploy dev cycle.

I've got the Eclipse maven plug in, and I've made a Debug Configuration of
type "Maven Build" but I'm not sure what to put for the goal.

Something like "run org.mypackage.Start" ?

Thanks for any clues,
-- Jim.

Re: multiple feedback panels in same page

[Jim Pinkham]

I just had this page with 2 forms issue - each form has some
RequiredTextFields, and some fields with custom StringValidators that I
didn't want to change from error to form.error.

This thread got me 90% of the way there, but

new FeedbackPanel("feedback", new *Container*FeedbackMessageFilter(myForm))

did the trick for my situation.

Just thought I'd mention it for benefit of fellow googlers in case they try
*Component*FeedbackMessageFilter and wonder where the messages went...

Re: mvn jetty plugin not compatible with wicket

[Jim Pinkham]

This works for me, although if anyone can think of a better way to get the
filtered version of jetty-xml during mvn jetty:run, that would be cool -
seems a bit odd the way I've got it now:

 
  
   
false
src/main/resources
   
   
true
src/main/java

 **


 **/*.java

 true

  1.5

 
 
  org.apache.maven.plugins

(Profile part not shown sets up the filters)

Hope this helps,

Re: Multiple Copies of One Wicket App

[Jim Pinkham]

I have a follow-up question related to this.

My current setup is simply myclient.war with my web.xml having one
filter-name and one filter-mapping with url-pattern /*  so my home page is
myhost/myclient.   Life is good, but now I'm growing!

What I'd like to do is have separate versions of the app for several
clients.  So I'd rename myclient.war to generic.war, then have
several filter-mappings with url-pattern  /myclient and /mynewclient.   I
think this way I can have specific init-param entries for each one and get
the right database and so forth for each one - that's pretty much how I
read this answer, so that's great as far as it goes.

So my followup question is, I have some ThisPage.properties files with text
specific to my current client, and I'd like to have some way to load
properties in a consistent way, perhaps ThisPage.properites, with overrides
taken from myclient.properties - kind of like locales, but not exactly.
For that matter, I might even do the same thing with ThisPage.html and
ThisPage.mynewclient.html files.   I also have a few
MyApplication.properties.  Perhaps I could refactor these (there aren't too
many) into some other organization?

Anyone have any tips for me in this regard?  I don't anticipate any other
future locales other than default US, but I'd hate to break from convention
allowing for that if there's a better way.

I'm still on 1.3.7 btw, if that matters.

Thanks,
-- Jim.

Re: Handling Ajax session expired

I think this suggestion is worth condsidering more carefully:

>No, that is not the proper solution. They are the same application.

OK, but could you deploy multiple copies of the same app to different root
contexts - that would give you the info you want in each URL and thus be
able to do different home/error pages with some config along with each copy
of the app.  Seems worth exploring whether your Silos might divide well in
this manner, maybe with a bit of work, but probably more likely to happen
than what it seems like you are looking for, which doesn't sound (just one
casual observer's option) broadly applicable enough to warrant framework
inclusion.

Re: Setup for stepping into wicket source in eclipse

[Jim Pinkham]

You may also want to check out JadClipse - it lets you step into
de-complied-on-the-fly versions of source code from the jar/class files of
any 3rd party tool.

http://jadclipse.sourceforge.net/wiki/index.php/Main_Page

Not as good as the fully commented source of course, but often good for a
quick answer to what's going on.

Re: Highlight some words in the markup content

[Jim Pinkham]

I'd be interested to know if anyone else is using this technique for search
highlighting with a DataTable.

http://pastebin.com/m5446797d

The data in my grid may contain HTML, so that makes it considerably more
complicated (my first attempt didn't address this problem).  I'd love to
know if someone else has a better/simpler way, although this does appear to
work fine, it took a day to come up with.

In general, I kind of like the idea of separating this concern from the
model, whose purpose is just to get the data, and think of this search
highlighting as more of a decorator that applies to the entire grid rather
than any particular column, since I've got several PropertyColumn subclasses
(LinkPropertyColumn, ImagePropertyColumn, NonEscapedHTMLPropertyColumn,
...etc).

Hope this helps someone else.

Thanks,
-- Jim.

img tags from external src slow down my page

[Jim Pinkham]

Hi,

I have an AjaxFallbackDefaultDataTable on the main page of my Wicket
app with an image column like this:

columns.add(new ImagePropertyColumn(new ResourceModel("imageURL"),
"imageURL"));

My item model has an imageURL string property backed by a database
column, and it pretty much works OK.

I don't need to store any images, bandwidth is low, and it's simple,
but I have seen some users enter URLs to huge TIFF images that are not
properly sized, and it makes my page display take forever.   I'd like
to try to fix or prevent this.

I had a few ideas:

1. a note on the item entry page asking users to 'please don't do that'.   :)
2. add an ImageURLValidator to check the image size somehow... hmmm...
3. find some utility to help read the image, properly size it, and
store a local copy with my own id (filesystem should work fine)
and let my model's imageURL property point to it.

I'm trying to write this so it could scale up a bit without getting
crazy - This app lists items for a charity fundraising auction event,
so access is light for several weeks, then peaks at about 300 hits per
day (I know, not much) for a few days.  But on those peak days, I'd
like it to be fast (despite the decrepit old server it's running on).

I've got about 300 items to show on a single page (users prefer a
simple scrollbar without pagination).   Also, I should mention that I
have a search form that 'decorates' the matching text as it filters
rows, and I'd like to make it fast enough to take away the search
button and just ajax refresh on keypresses.

Thanks for any suggestions, links to examples ...etc.
-- Jim.

Re: Google App Engine and Wicket

[Jim Pinkham]

I've followed with interest all the wicket on GAE threads I can, and these
all seem to address necessary minor tweaks to get it set up, but the one big
thing I haven't seen much discussion on is the BigTable storage system,
since we wouldn't be able to use MySQL.

Maybe that's the whole point for some folks looking for high scalability,
but from my perspective, I'm more interested in the idea of a free
turnkey(ish) Java hosting environment.

I'd like to be able to resell my wicket app (it's a fundraising auction
system designed for nonprofits) to lots of tiny churches or other nonprofit
organizations - they typically have no IT experience, so bypassing the
hosting concerns could be a big win.  Plus, the system would be ultra low
traffic by google standards especially (maybe 8 concurrent users tops per
org during peak demand!).

Right now it's 'incubated' as an old underpowered Windows 2000 server
running Jetty sitting in a closet at my church, where the business class ISP
licence agreement legally permits it.  Seems like quite a leap to be
considering GAE, but if it's free and folks trust the availability and I can
easily configure it for each additional client, that could work out pretty
well for me.

But of course my system is all heavily SQL oriented - seems like this would
be a pretty fundamental rewrite for me to go to BigTable, and I was
wondering if any other wicket developers were also attracted to this type of
system, for these or other reasons, or whether I should just shell out for
some shared hosting blades and go for it?

Thanks,
-- Jim

Re: serialVersionUID

[Jim Pinkham]

I'm suprised no one has mentioned the runtime cost of computing a default
serialversionid which is avoided if a constant is supplied.   I used to make
it a habit for this reason.

This thread made me curious if that was really true, so I googled a bit and
found this 
articlewhich
found no such benefit, and suggests we needn't bother.  I think I'll
turn off the Eclipse warning instead.

Re: Can client cache pages effectively?

[Jim Pinkham]

A quick follow up in case anyone else was curious about how this is going:

I ended up using ehcache page cache filter for a simple page that just
displays 'current' items (calendar view of events) based on a db query.  No
forms (state) on this page so it works pretty well.  In my DAO that does
updates, I clear the cache.  Very simple, works great.  (Only catch I ran
into is that my menus change when I have a session and I'm logged in as
super-user, so I have to make sure I don't let that version of the page be
cached - I do that by adding 'super' page parameter so URL is different
and filter is set to only cache the 'normal' version.

So, that still leaves me with my main catalog page, which is primarily a
similar list of items, but it also has some active content (in particular, a
search form).

So my bright idea (tm)  (i.e. I'd love to hear critiques before I get too
far along with it) is the following:

Make a new page for just the data grid, with page parameters including the
search string and last-modified date (and super-user login because I get
some edit links and such with that).  Mount it and ehcache it, and override
setHeader so it becomes client cache-able.   Then, my outer catalog page
with the search form on it just uses an IFrame to display the grid data
(easy to keep track of last-modified globally).  Same clear method in DAO
dumps the cache whenever a change is made.

Also, I'd want to make a robot no-follow thing to avoid google trap on that
page.  Could this actually be a legitimate use of otherwise dodgy IFRAME ?

Sound like a good plan?

Thanks,
-- Jim.

Re: How To Download Excel File?

[Jim Pinkham]

Another way I'm using is like this (it works best if your clients have excel
installed of course)

Markup:  http://pastebin.com/m41ee5cbe

Java:  http://pastebin.com/m488291d4

With the most important bits being:

@Override
protected void configureResponse() {
super.configureResponse();

getRequestCycle().getResponse().setContentType("application/x-msexcel");
}

and then a simple DataView with something like this:
...

  Excel Download
  
  




Name
... more ...


 

That makes most browsers open a dialog box where the user can open (usually
in excel) or save the html - no binary conversion to excel's file format is
really needed - excel can read HTML just fine.  So if you are just doing a
simple tabular report like I'm doing here, this could be a good option for

Re: Can client cache pages effectively?

[Jim Pinkham]

Jeremy,

Thanks for your thoughtful reply - Scenario is exactly right.
I played around with page headers to make the whole page cacheable, but ran
into several problems - I have a search form, and there's an 'admin' login
that enables edit links.  So it's really a stateful page, but I want to
speed up the most common state.

The bulk of the content is from an AjaxFallbackDefaultDataTable with
sortable columns. I re-sorted a column with the Ajax Debug window open to
measure it's data size - about 225000 chars.  My database search takes
64ms.  Overall client repaint time is about 2 sec with browser on
localhost.  I haven't found the right hook to measure total wicket response
time yet, but it appears pretty quick - so that's why I thougth it made
sense to focus on client caching.

Before I give up entirely on this idea, I'm wondering if it might make sense
to make the grid a public Resource, which I'm hoping the browser would treat
like an image.  I can afford a separate db query to just get my
max(lastModified), which might let me save the time to generate HTML, which
looks as though it could be my bottleneck.  If this way is too hard, I'll
give up, but it sounds do-able - what do you think?
Thanks,
-- Jim.

Re: Can client cache pages effectively?

[Jim Pinkham]

Thanks Jerry; I think that applies only to static pages.

My next idea is to try overridding WebPage.setHeaders and just set the

response.setHeader("Cache-Control", "max-age=3600, must-revalidate");

response.setHeader("ETag", "1");  // I'll use a checksum on the data coming
back from my search (Even better would be a checksum on the rendered page
data - any idea how to do that?)
Initial test (above) seems promising...

Thanks,
-- Jim.

Re: Can client cache pages effectively?

[Jim Pinkham]

Changing my search query to this got some better hits:
http://lmgtfy.com/?q=cacheability
So, allow me to refine my question based on that - has anyone tried some of
these approaches (see first result from above) to generrate and dump content
to a static file (renamed if it chages) and having the wicket home page be a
redirect to that file, or something like that?

Thanks,

Can client cache pages effectively?

[Jim Pinkham]

I've found a few posts about how to mark dynamic pages so they won't be
cached.

I've got a different situation that I think is fairly common - the 'home'
page of my app is effectively a (cheesr-like) catalog of items that changes
infrequently.   Users didn't like paging, so it's about 300 items in a
simple scrollable page.  Once a user views it, they often drill down into an
item, then use the back button (or sometimes the Home link) to re-display
it.

The db query is actually pretty fast; I think the bottleneck seems to be
fetching the HTML.

My question is, can I use some kind of header caching hint with a version
number so that once the content is identified as being the same as a
previously fetched page, the user's browser will repaint it from a local
cache?  (I know this is typically done with images, but I was wondering if
this would make sense to do also do with content that technically 'dynamic'
but actually is 'fairly static' ?   (I say version number rather than time
to expire so that in case I add/change an item I can increment the catalog
version)

Thanks,

Re: DataView vs ListView

[Jim Pinkham]

Also, in MySQL syntax, you've got stuff like this that gets you right to the
page you want:

 sql = "Select ... whatever ..";
 sql += " limit " + query.getFrom() + ","+query.getCount();
Oracle and other variants have similar options - I agree conn pool probably
makes most difference.

Re: DownloadLink, BIRT report

[Jim Pinkham]

I don't know about BIRT, but I recently did an output to Excel page.  You
link to it like any other page:


http://wicket.apache.org/";>

Auction Excel Download






 
 
 

That meta content in the head is more for documentation - it doesn't seem to
work without the final step below:

The Java code looks something like this to populate the table:

add(new DataView("rows", new MyDataProvider()) {
public void populateItem(final Item item) {
item.setModel(new CompoundPropertyModel(new
DetachableXYZModel(item.getModelObject(;
item.add(new Label("name"));

And the final magic makes it ask if you want to open it with excel:

@Override
protected void configureResponse() {
super.configureResponse();
getRequestCycle().getResponse().setContentType("application/x-msexcel");
}

That worked for me - hope it helps.  (Also note you can output a mix of
literal data and formulas)

I use web app to collect data, then word merge templates for reports.

Re: Why don't I get onSubmit() for my form?

[Jim Pinkham]

Thanks to all who helped find this - yes, it was failing to validate my
input numeric "123.45".

I came up with this fix in my application class:

protected IConverterLocator newConverterLocator() {
converterLocator.set(Double.class, new AbstractDecimalConverter() {
private static final long serialVersionUID = 1L;
IConverter delegate = DoubleConverter.INSTANCE;

@Override
public String convertToString(final Object value, Locale locale)
{
return Currency.getInstance(locale).getSymbol() +
super.convertToString(value, locale);
}
@Override
protected Class getTargetType() {
return Double.class;
}
public Object convertToObject(String value, Locale locale) {
if (value != null &&
value.startsWith(Currency.getInstance(locale).getSymbol()))
value = value.substring(1);
return delegate.convertToObject(value, locale);
}
});

Thanks,
-- Jim.

Re: Why don't I get onSubmit() for my form?

[Jim Pinkham]

Thanks!

That helped me find the problem - I broke it when I added this to get $
prefix for my Double (in this app all doubles are currency) values:

converterLocator.set(Double.class, new AbstractDecimalConverter() {
private static final long serialVersionUID = 1L;

@Override
public NumberFormat getNumberFormat(Locale locale) {
return NumberFormat.getCurrencyInstance();
}
// from DoubleConverter
public Object convertToObject(final String value, Locale locale)
{
final Number number = parse(value, -Double.MAX_VALUE,
Double.MAX_VALUE, locale);
if (number == null)
return null;
return new Double(number.doubleValue());
}
@SuppressWarnings("unchecked")
protected Class getTargetType() {
return Double.class;
}
});

Seemed like a good idea, except I forgot about input!  oops!

So, I'll take away from this the lesson to always have a feedback panel
someplace on any form.

Thanks again,
-- Jim.

Why don't I get onSubmit() for my form?

[Jim Pinkham]

I can't figure out why my form's onSubmit isn't firing when I click my
submit button.

Can anyone see what I've done wrong?

Here's the HTML:  http://pastebin.com/m5b1440a0

Here's Java code: http://pastebin.com/m4a217d31

At line#114, onSubmit is not being called.  I've tried lots of different
things - I've tried adding a wicket:id to make it a Link, it gets execution
flow, but without the model having been updated yet, which isn't really what
I want.   Similarly, I can make it a Button, but that also doesn't get the
onSubmit.

Any tips for me?  I feel like I'm missing something really simple...

Thanks,

Re: Basic print.css question

[Jim Pinkham]

Yep - and I flunked!  :)   I feel like a doofus for missing that # vs .
basic CSS thing, but thanks to all who responded.  It's the simple stuff
that trips me up - All the 'wicket-way' anonymous classes and such - Java is
no problem for me, but the web stuff I'm still learning.

Anyway, if anyone want to see (critique) my deployed app, I'm putting it up
today at www.firstuucolumbus.org/auction It's for a fundrasing service
auction where folks sign-in and offer dinners and such, then we have a big
event to sell items.
There's an admin login that makes the inmethod grid columns editable (for
proofreading) and does all the back-end sale entry and such.
Oh,and its deployed on a slow old server.
Thanks again!

Re: Highlight some words in the markup content

[Jim Pinkham]

I've got a few embellishments to that idea that others might enjoy.  These
include the ability to use on non-string properties, and caching the last
compiled pattern (maybe uses a bit less CPU than replaceAll each time).

protected static class HighlightingModel extends LoadableDetachableModel
{
private static final long serialVersionUID = 1L;

private transient IModel text;
private transient IModel searchWord;
private transient Pattern lastp;
private transient String lastSearch;

HighlightingModel(IModel text, IModel searchWord) {
this.text = text;
this.searchWord = searchWord;
}

@Override
protected String load() {
String srch = (String)searchWord.getObject();
Object object = text.getObject();
String txt = "";
if (object != null) {
IConverter converter =
Application.get().getConverterLocator().getConverter(object.getClass());
txt = converter.convertToString(object,
Session.get().getLocale());
}
if (srch != null) {
Pattern p = null;
if (lastp != null && srch.equals(lastSearch) )
p = lastp;
else {
try {
p = Pattern.compile(srch, Pattern.CASE_INSENSITIVE);
} catch (PatternSyntaxException e) {
if (e.getIndex()>-1) {
srch = srch.substring(0, e.getIndex());
try {
p = Pattern.compile(srch,
Pattern.CASE_INSENSITIVE);
} catch (Exception e2) {
srch = null;
}
} else
srch = null;
}
}
if (p != null) {
Matcher m = p.matcher(txt);
return m.replaceFirst("$0");
}
}
return txt;
}

super.onDetach();

Inmethod grid with more edit controls

[Jim Pinkham]

I'm just getting started with inmethod grid and loving what it does so far.

Now I'd like some to use other input controls such as checkbox, radiobutton,
datepicker, or ChoiceList.

I see EditablePropertyColumn has newCellPanel I could override to return
Panels with various input component types in edit mode.

Before I embark on this, does anyone have other ideas about how to approach
this?

Panels could benefit from the way TextFieldPanel puts feedback into title,
which suggests to me a new class such as AbstractEditablePropertyColumn
where this could be moved.  I also notice that CheckBoxColumn has the
concern of being a row-selector that could be separated into
RowSelectingCheckBoxColumn, for example (leaving the name CheckBoxColumn
available as the obvious choice for editing any boolean column).

I also like the idea of the light-weight propertycolumn (currently newCell
just puts value into response) to use these same corresponding panels in
disabled mode - maybe for radio and checkbox render the corresponding
control markup as disabled (display-only) to retain the light-weightness but
also have a richer display.

I know that's a lot to ask, but it seems a reasonable target to aim for...
Thoughts?

Thanks,
-- Jim.

Re: Inmethod Grid with wicket 1.3

[Jim Pinkham]

Nice.

OK, now I'm getting more ideas - I added more columns, but now I'd like some
to use other input controls such as checkbox, radiobutton, datepicker, or
ChoiceList.

I see EditablePropertyColumn has newCellPanel I could override to return
Panels with various input component types in edit mode.

Before I embark on this, perhaps you have some ideas to share about this?

If there is some minor refactoring involved, I'm not afraid to jump in and
help if it also benefits others.

For example, these Panels could benefit from the way TextFieldPanel puts
feedback into title, which suggests to me a new class such as
AbstractEditablePropertyColumn where this could be moved.  I also notice
that CheckBoxColumn has the concern of being a row-selector that could be
separated into RowSelectingCheckBoxColumn, for example (leaving the name
CheckBoxColumn available as the obvious choice for editing any boolean
column).

That could be step one, then once that works, the next step could be for the
light-weight propertycolumn (currently newCell just puts value into
response) to use these same corresponding panels in disabled mode.

I know that's a lot to ask, but it seems a reasonable next level to aim
for...   Thoughts?

Thanks,
-- Jim.

Re: Inmethod Grid with wicket 1.3

[Jim Pinkham]

Got that working.  Now, since I'm using row selection to indicate
deletion, and since I've disabled row multiselect (so rows get deleted
one-at-a-time), I'd like to give the checkbox column a header: new
Model("Delete"), but I don't see a way to do that.  I was able to
override getHeaderModel, but isVisible is false in the HeadPanel.

Can I visit the component by attribute name somehow to do it?

Really appreciate the help - it's starting to look good.  Since I'm
using a pageSize of 500, avoiding the page refresh allows me to have
super-simple yet snappy interface for non web-savvy proofreaders.

Thanks,
-- Jim.

Re: Inmethod Grid with wicket 1.3

[Jim Pinkham]

OK, now a question about using inmethod grid:  (I really like this
grid, by the way - awesome work Matej!!)

On a grid with some editable columns, I override setItemEdit to use
the same grid in non-editable mode, and also to save the edits.

if (enableEdits)
columns.add(new SubmitCancelColumn("esd", new 
Model("Edit")));
DataGrid grid = new DefaultDataGrid("grid", new 
MyDataSource(), columns) {
@Override
public void setItemEdit(IModel rowModel, boolean edit) {
if (enableEdits) {
super.setItemEdit(rowModel, edit);
if (!edit)
// dao save row goes here
}
}
};

I think the IDataSource is very clear, but it is for loading. For
updating, is this appropriate, or am I overlooking a simpler/better
way?

Then, I would like to add a delete link inside the SubmitCancelColumn
- has anyone already done that?  I'm thinking it would only be visible
if editMode is false to share the same screen space with the ok/cancel
icons.

I suppose a blank line to add a new row at the end would be nice too,
but I think I can figure that out myself...

Thanks,
-- Jim.

Inmethod Grid with wicket 1.3

[Jim Pinkham]

I'd like to use inmethod grid in my charity auction project.

I've got a slightly modified version of one of the grid-examples using
DataGrid like so:

DataGrid grid = new DefaultDataGrid("grid",
AuctionApplication.get().getDao().getItems(getYear()),  
 // returns
IDataSource
Arrays.asList(new IGridColumn[] {
new PropertyColumn(new ResourceModel("id"), "id"),
new PropertyColumn(new ResourceModel("name"), "name"),
// I'll try editable columns here once I get
basic display working...
new SubmitCancelColumn("esd", new Model("Edit")),
}));
add(new Form("form").add(grid));

I'm getting this error at runtime I don't understand:

NoSuchMethodError: org.apache.wicket.MetaDataKey: method ()V not found
at com.inmethod.grid.common.AbstractGrid$4.(AbstractGrid.java:908)
at com.inmethod.grid.common.AbstractGrid.(AbstractGrid.java:907)
at org.firstuucolumbus.CatalogPage.(CatalogPage.java:43)

Unfortunately, I'm a total Maven newbie, so I'm guessing something
must be amiss in pom.xml (below)

or the way I'm using it:  mvn clean install eclipse:clean eclipse:eclipse

(Then I usually run Start from Eclipse)

Would someone wiser in the ways of inmethod and/or Maven care to give
me a hand here?

Any help much appreciated.

Thanks,
-- Jim.
