RE: Hippo's patch for wicket ids

[Bernhard Michal]

 
Works for me, your xpath must be wrong. Your syntax is ok. Either there
is no  element (link) with attribute
wicketpath="tablePanel_leftList_tableList_pojoList_18_nameCell_namePanel
Link_name" or there is no div tag inside an  element...


-Original Message-
From: Douglas Ferguson [mailto:doug...@douglasferguson.us] 


Does anybody have sample of how to do this?

I'm getting this error when I try to use the wicketpath

  [error] Element //a
[...@wicketpath
=
'tablePanel_leftList_tableList_pojoList_18_nameCell_namePanelLink_name
']/div not found

Column filtering on inmethod datagrid

[Linda van der Pal]

I've tried to add column filtering to the inmethod datagrid by creating 
a new class ChoiceFilteredPropertyColumn which extends the new class 
FilteredPropertyColumn, which extends the inmethod PropertyColumn and 
implements the new interface IFilteredColumn. In other words, I've 
merged two sets of classes: the column classes of the inmethod datagrid 
package and the filtered columns that come with wicket extensions.


For some reason however, this isn't working yet. At first I thought that 
the classes themselves weren't working properly. But then I saw that the 
filters ARE included in the HTML. They simply don't show up on the 
website itself. And I can't figure out why. I didn't see any 
style="display:none" or anything obvious like that. Does anybody have 
any pointers that I could look for? (I'd love to include some code, but 
it's rather bulky and I have no idea what portion to include to be helpful.)


Regards,
Linda

Correct, this patch (PD) we use in order to get Selenium to work, and
it works pretty well.  What is basically the case is that Wicket uses
a single global counter which ever increases to generate IDs.  Because
hierarchy can change, components are added this ID is not bound to the
wicket component, leaving to a new ID the next time round.  What this
patch does is to tie the generated ID to the wicket component, but
that's not the whole story because if anything is different in your
hierarchy the paths will still change.  It will work for selenium if
you do everything exactly the same, but that's hard to maintain/
What you need is that when generating a ID, the ID is generated with
the knowledge of the component, such that you can generate the ID
based on the domain knowledge of your component.  The crux is that the
wicket method in the Session to generate an ID had no parameters,
while if it would get the component requesting the ID, then an
subclasses wicket Session instance can incorporate this knowlege.
Basically the patch is just adding the parameter to that wicket method
and the other 80% of the code is just making sure everything is
backward compatible.

How can one use this subclassing, well, for instance you have some
kind of listing component on your page that enumerates items in your
database.  Because the content of the database changes, the hierarchy
will change, rendering IDs useless.  Now you could resolve this by
letting the component that lists a single item explicitly set the
markup ID, but if this itself is a Panel containing subitems, then you
need to set the IDs of all those subitems too.  That becomes nasty bit
of either passing arguments or traversing the tree.  However, with the
patch you can put this logic in the session.  When an ID needs to be
generated, use the ancestor tree of the component for which the ID is
needed up to a stable ID component (the one which knows which database
element, and then instead of using a global counter, use a counter in
that component.  This was the ID has become stable, and most of the
logic is where is belongs, the Session instance generating IDs.
Maybe not the nicest example, because a lot of knowledge is infused in
your Session class, but there are better cases available (we have a
plugin system for wicket, where we can use a quite generic mechanism).
 It's illustrative though I hope.

It's probably a good idea to have a specialized implementation of

older pages are used for the duration of the session, and typically
just keeping the last few in memory suffices.


I tried to get started with an implementation of ISessionStore for the 
app engine. However, I would rather opt for the Memcache Service [1] 
instead of the datastore due to performance and quota issues. The 
MemcacheService provided by GAE is in effect a JCache implementation.


Regarding a Memcache-based implementation, there rise the following 
questions for me (please take into account that I am rather a 
wicket-beginner):


1) Should the implementation be a specialization of ISessionStore or 
rather IPageStore?
1a) In case of ISessionStore, is it enough to implement the 
"MemcacheSessionStore" like the HTTPSessionStore, but instead of putting 
things into the HTTPSession, they will be put in the Memcache?
1b) In case of IPageStore, does it make sense to adopt some principles 
of the DiskPageStore (and basically switch the file-based saving to a 
cache-based saving)?
2) I digged a bit through the mailing list: Would an implementation such 
as 1a) affect the back/forward button behavior of the browser?


Thanks in advance for your thoughts.

Variation of parent component isn't passed to image - Bug?

Re: Reusable components and wicket:id

[Pedro Santos]

Hi Tómas,
What the form component RadioButtonGenerico receive as id, the validation
message will use as label. The code should generate the outputs:
* Field 'rapidezAtencion' is required.
* Field 'explicacionClara' is required.

your report output :
  
is an generic markup or always the "score" id is placed on html? If so, can
you send the panel html? what wicket version are you using?

Variation of parent component isn't passed to image - Bug?

[Liz Huber]

Hi,

I came across a problem an other group member has already written about
(please have a look his post
http://markmail.org/thread/auqhcd66zwsflt33#query:wicket%20image%
20parent%20variation+page:1+mid:auqhcd66zwsflt33+state:results). But he
didn't get an answer.

Actually the variation of a component is passed to its child component.
But this doesn't work for images, because when their variation is
requested they don't have a parent yet.

I don't know if this is a bug or I should override some methods.

Maybe anyone had to deal with this behavior before.

Thanks in advance,
Liz

Re: Re: Google App Engine and Wicket

Hi,

The Terracotta SecondLevelCacheSessionStore does not contain any Terracotta
specific implementation or dependencies, and should work fine on AppEngine
(I haven't tested it though).

All it is is an implementation of IPageStore, where the pages are serialized
to byte arrays (like the disk store), and then these byte arrays are stored
in the http session, rather than on disk.  I have attached the file in this
thread so you dont need to dig around in the terracotta svn repo.

to use it do this in your application class:

@Override
public ISessionStore newSessionStore() {
 return new SecondLevelCacheSessionStore(this,  new
TerracottaPageStore(100));
}

the 100 is the number of versions of pages you want to keep, and can be
customized as you feel appropriate.

Oh, sorry I just realized that it has the terracotta licence header on it,
had I realized i would have removed it.  That's because the version of the
file i had to hand was from the terracotta forge svn repo, and code in there
has to have their licence.

Originally it was Apache 2 licensed and I would treat it as such.

Sorry for the confusion,

that's the textfield:

Hi,

We are building a simple survey with Wicket.

Essentially, we have a lot of RadioGroup components repeated all over

example:

Are you happy with X?

We also have our survey page with a feedback panel and a form. Inside

How to reach a component in ListView

[pieter claassen]

I have an abstract class that adds a ListView to the page in the
constructor. In the constructors of my children, I would like to set some of
the rows in the ListView invisible. How do I reach the Wicket Components
that were added to a ListView from outside the Listview.

e.g.
public abstract ListDocumentsForObject{
public ListDocumentsForObject() {

ListView documents = new ListView("documents", documentlist) {

@Override
protected void populateItem(ListItem item) {
   .
Link delete = new ConfirmLink("delete") {


public final class ListDocumentsForUser extends ListDocumentsForObject {
public ListDocumentsForUser(...) {
super(...);
setAllDeleteButtonsVisible(false);   <-I want to set all or some
of the delete links as invisible.


Thanks,
Pieter

Re: How to reach a component in ListView

[Jeremy Thomerson]

Better to access whether or not they should be visible from within the
components (inside the listview) themselves.  On your links, override
isVisible and have it call to some method on ListDocumentForObject that
returns boolean of whether that link should be visible.  Then this method
could be overridden by child classes with different logic.

Re: why is the model empty?

That's not an immutable model.  It's equivalent to new Model("") -
which is fine for this use.  Assuming the text field and the button are
within a form, and that he sets the value of the textfield programmatically
on the page, and submits the form, the model should be updated by the time
he gets to this onSubmit method.

"sets the value of the textfield programmatically
on the page, and submits the form, the model should be updated by the time
he gets to this onSubmit method."

How do you mean that? I think wicket sets the model automaticly because the 
model is attached to the component.

Yes - that's what I'm saying.  On the webpage, presumably with JS, he is
saying that he is setting the value of the text field.  Then when it's
submitted, Wicket should update the model before he gets to onSubmit

AW: why is the model empty?

[Peter Arnulf Lustig]

I am submitting a textfield in a form to wicket. Just the standard HTTP Post -- 
And everywhere it functions well -- I just can't get it why it won't function 
there.

And I don't utilize any JS (Ajax etc.) for that task! It's weird.

Yes - that's what I'm saying.  On the webpage, presumably with JS, he is
saying that he is setting the value of the text field.  Then when it's
submitted, Wicket should update the model before he gets to onSubmit

Re: why is the model empty?

[Jeremy Thomerson]

Did you look at the javadoc?  [1]

It says:
Sets the defaultFormProcessing property. When false (default is true), all
validation and
form updating is bypassed and the onSubmit method of that button is called
directly, and the
onSubmit method of the parent form is not called. A common use for this is
to create a cancel
button.

So, yes, that would prevent the model from being updated.

Re: why is the model empty?

[Jeremy Thomerson]

Well, don't know what to tell you.  It bypasses validation, which is
required in order to set the models to their values.  If you submitted
"akj123" in a text field that was an Integer, we could only set it after
validation (which in this case means the value could not be set on the
field).  So, bypassing validation means that you must also bypass getting
your models updated.  You can call textfield.getValue() (or similar - can't
remember exact name) to get the raw submitted value.

Re: Reusable components and wicket:id

Hi Tomás, I didn't found the problem. The feedback panel get:

* Field 'rapidezAtencion' is required.
* Field 'explicacionClara' is required.
* Field 'resolucionProblema' is required.

just as expected...

Re: Variation of parent component isn't passed to image - Bug?

[Igor Vaynberg]

styles and variations are not passed down through the hierarchy. one
must override getvariation()/getstyle() on each component that needs
to be different afaik.

Re: Reusable components and wicket:id

[Tomás Rossi]

Yes, but I have 2 panels in the same page, and get:

* Field 'rapidezAtencion' is required.
* Field 'explicacionClara' is required.
* Field 'resolucionProblema' is required.
* Field 'rapidezAtencion' is required.
* Field 'explicacionClara' is required.
* Field 'resolucionProblema' is required.

And I want something like:

* Field 'panel1-rapidezAtencion' is required.
* Field 'panel1-explicacionClara' is required.
* Field 'panel1-resolucionProblema' is required.
* Field 'panel2-rapidezAtencion' is required.
* Field 'panel2-explicacionClara' is required.
* Field 'panel2-resolucionProblema' is required.

So that I can change those labels with a properties file later.

Re: Reusable components and wicket:id

[Pedro Santos]

now I understand
1 - you can use different feedback panels for each panel
2 - you can write a custom model for the component label
here is a draft, you can create a concrete class from, can override the form
component getLabel, can set the custom model on the RadioButtonGenerico
constructor...

myRadioButtonGenerico.setLabel(new AbstractReadOnlyModel()
{
@Override
public String getObject()
{
return getParent().getId() + "-" + getId();

Re: Reusable components and wicket:id

[Tomás Rossi]

Thanks! That worked.

Though, I'd love for wicket to provide an automatic mechanism for this 
kind of stuff. Each instance of a reusable component could be mutually 
independent, even if used in the same container (at least that was my 
intuitive idea).


Kind regards,

columns. Paging].  I know would like to change the look and feel of the
data table.

 

I would like to be able to change the navigation toolbar so that the
paging links appear directly to the right of the "showing 1 to 15 of X"?
The html file has the paging links defined as a text-align: right in the
html and it can't be overwritten with css classes.  This is great for
narrow width tables but a table that scrolls horizontally the navigation
is lost on the far right.

 

It looks like the navigation toolbar is automatically added by the
constructor of the AjaxFallbackDrfaultDataTable.  Is there a way to use
my own Navigation Toolbar or make the changes so I can control the
layout of the navigation toolbar.

 

Thanks.

 

 

Re: Reusable components and wicket:id

[Igor Vaynberg]

thats why formcomponents take models for labels. you can give it a
resourcemodel that uses the parent's id as the resource key and
achieve what you want.

 Hi Tomás, I didn't found the problem. The feedback panel get:

Re: Reusable components and wicket:id

[Tomás Rossi]

Wait a minute...

I made a "PantallaEncuesta.properties" with:

panelTelefonico-rapidezAtencion=Rapidez en la atención (telefónica)
...

Then I expected it to yield:

* Field 'Rapidez en la atención (telefónica)' is required.

But it still prints:

* Field 'panelTelefonico-rapidezAtencion' is required.

Not what I want... What's wrong? :(

Model property name different than wicket:id, is possible?

[Manuel Corrales]

Hello. I have a (i hope) reusable panel. This panel has a textField, a
hiddenField and a link that open up a modalWindow. Then you can select an
item from a list in the modal window and the field and hidden field
completes according to the selected value. I want the hidden field to be
"binded" with a property of the model I am using in a form (using
CompoundPropertyModel). I intend to use this panel in several forms in my
application, the problem I have is that the field name of the model object
is different on every form, and the wicket:id is the same (because it is the
same hiddenField).
How can I solve this? Is there a way of having a wicket:id with a different
name than a model property name?

Please ask for anything you need to help me, I don't know if I was clear on
my problem.

Thanks in advance!
Manuel.

Re: Model property name different than wicket:id, is possible?

[Manuel Corrales]

Ok, I have found a few things but still can't figure this out. Apparently
the BoundCompoundPropertyModel is what i need, but it is deprecated. And I
have read the javadoc but still can't figure out how to achieve having
wicket:id on HTML different than the property name in the model. The javadoc
mentions CompoundPropertyModel bind method, but can't figure out how to use
it.
Any help?

Thanks!

Re: Model property name different than wicket:id, is possible?

[Pedro Santos]

 the problem I have is that the field name of the model object
is different on every form, and the wicket:id is the same

you has:
public class ObjectThatGoesToModel{
   private Object propetyThatGoesToSomeForm;
   private Object propetyThatGoesToOtherFormInSomeSituations;
}
??

I think you can use

new PropertyModel(compondedPropertyModel, "propetyThatGoesToSomeForm")
or
new PropertyModel(compondedPropertyModel,
"propetyThatGoesToOtherFormInSomeSituations")

Secured/Constraint IDataProvider and DropDownChoice choices

[Roman Ilin]

Hi *,

I develop WebApplication where database records belong to different
organizations.
I use AjaxFallbackDefaultDataTable to present tabular data. User from
some organization is allowed to see his organization data only.
To reach this I implement custom IDataProvider for every table.

Is there some way to have generic IDataProvider which constraints
shown data rows.
Pagination and sorting, filtering of data should work as well :)

I have the same problem with DropDownChoice. There choices depend on
logged in user/organization.

I read Wicket Security Wasp/Swarm tutorials but haven't found this
functionality there.
You can have secure model but you can't restrict list of models.

Or I'm wrong?


Regards

public void download(String filename, byte[] filedata){
setRedirect(false);
WebResponse response = (WebResponse) getResponse();
response.setAttachmentHeader(filename);
response.setLastModifiedTime(Time.now());
response.setContentType("application/octet-stream");
response.write(
new ByteArrayInputStream(filedata));
response.close();
}


item.add(new Link("download"){
{
add(new Label("filename",
eaAuditProgramAttachment.getFileName()));
}
@Override
public void onClick() {

((BasePage)getPage()).download(eaAuditProgramAttachment.getFileName(),
eaAuditProgramAttachment.getEaBlob().getBlobData());
}
});


If I replace this link with AjaxLink it will not work  and I must use  an
ajaxlinkplease tell me how can I use ajaxLink for download

Audit Trail For Fatal Error

[Douglas Ferguson]

I have a feature on our error page where users can submit a bug if  
they get a fatal error.

In some cases the stack trace is not of much value with out  
understanding what the user was doing.

I looked into the session and the pagemap but at first glance i didn't  
see any way of unraveling any details that may be of help in  
understanding their previous actions, is there something there that's  
maybe not apparent to me?

Re: Secured/Constraint IDataProvider and DropDownChoice choices

[Pedro Santos]

you can put user on session, and use this information as an filter to
queries than fill the lists on your application models...

Sure I save my user in session.
The problem is that I have to implement this filter functionality
every time for every component.

Re: Audit Trail For Fatal Error

[Pedro Santos]

if you serialize the pagemap object to an file and attache it on your error
report email? later you can set pagemape error analysis environment to
reproduce the user steps, seems possible...

Sorry. I do it for every query but normally every component has its own query.

I had application with components that override the isVisible method testing
for

return session.getUser().hasAccessFor(this)

but the major access logic is implemented on data access layer

My components should stay visible all time. But data should be
filtered by customer currently logged in.

Re: Page instantiated twice

[Esteban Ignacio Masoero]

Hi there. I'm bringing to life this old thread to ask whether this issue was
solved and how, because I'm experiencing something alike, which makes
session messsages to get lost ("consummed" by the first instance of the
page), and consecuently not shown by the second page instance.

Thanks,

Esteban

Too Many Files Wicket 1.4.1

[Adam Bender]

Greetings all,

Recently I have been performance testing a Wicket application (1.4.1) and I
am running into the dreaded Too Many Files Open issue. I have searched the
mailing lists and most of the trouble around this issue seems to come from
being in DEVELOPMENT mode so I made sure we were in DEPLOYMENT mode. When I
run 'lsof -p  | grep wicket-1.4.1.jar' I see over 1000 entries and it's
growing monotonically. This seems really unusual - why would wicket need
1000 copies of this jar open? An additional bit of weirdness came up when
our load tests stopped loading the embedded assets (css, js and images) in
each page - this seemed to cap the number of lsof entries at 5... This is
even weirder because our app serves these static items from httpd without
tomcat ever knowing about them. How could our loading of embedded items
really affect the number of file handles wicket needs?

For completeness we are running this app on Red Hat Enterprise Linx 5 with
Tomcat 6.0.20 and Java 1.6

Adam

Re: Page instantiated twice

[Jeremy Thomerson]

Have you followed the suggestions in this thread?

First, put a breakpoint to see what's instantiating the page - the most
likely suspect for an unintended additional instantiation is a bad link,
something like: new PageLink(new MyPage());   <--- shouldn't do that

If it's Wicket code, what code is it?  Why?  It might be stateless as
Martijn suggested.

Re: Page instantiated twice

[Douglas Ferguson]

You can also check your html to make sure there aren't any urls that  
would get loaded by the browser.

i.e. , , etc tags..

 Be
 happy :)

 Since it is stateless, Wicket has to construct the page with each
 request, until it is no longer stateless.

 If you have a form, override its getstatelesshint method and return
 false.

Hi,

we also had this issue, because (I think) we are running two different
wicket application in only one glassfish domain. Our resolution was,
that we are running now the glassfish domains with custom init scripts
with ulimit settings. Maybe this will help for you.

deployment mode just sets a default settings profile, if you manually
call getresourcesettings().setresourcepollfrequency() in your code you
can still reenable the resource watcher.

Re: Too Many Files Wicket 1.4.1

We have run with a limit as high as 10,000 files and our tests can  
bring it to the limit in 20 minutes, but that still doesn't explain  
why so many copies of the jar are needed - and only when we are also  
requesting embedded assets...

OT: choose a directory where users upload images

[Fernando Wermus]

Hi all,I am deploying an app in production and I have to create a
directory where users upload images and text files in the server. They only
are allowed to access this files to a wicket front page. Should I have any
consideration about wicket arquitecture or tomcat architecture? Should I
create a variable enviroment for accessing to this directory? Which would be
the best approach?

thanks in advance

Re: Page instantiated twice

[Esteban Masoero]

First of all, thanks to all of you for your help.
I haven't solved the problem, but I'm getting closer to it.
(something like: new PageLink(new MyPage()); <= I checked it and I'm not 
doing that. )


Here's what I've found out:

After debugging a lot, I find out that TWO REQUESTS are made. The first one as a 
consecuence of the user asking for that page, and the second one because in that page 
the following script is added at the end of  tag:
]]>*/

Can anyone tell me why is Wicket doing that? or what am I doing wrong?


|||
Here's the complete detailed description about what I am doing:

A UserStatusPanel that is always shown does *new Link("register")* with:
@Override
public void onClick() {
throw new 
RestartResponseAtInterceptPageException(UserRegistrationPage.class);
}

When the user gets to the page, submmits its registration data and the 
page sends an email with a link like: 
http://localhost:8080/ua?ua=2baab43f784b5b530b5347a50490bb0a


In my webApp, I've done:
this.mount(new QueryStringUrlCodingStrategy("/ua", 
UserActivationPage.class));

When the user goes to the previous mentioned link by a new tab, the 
following happens:

___
GET /ua?ua=2e129db15b6d6db5342ba5d328642262 HTTP/1.1
Host: localhost:8080

Connection: keep-alive
Cookie: JSESSIONID=78ehtk0o3y0w
___
=== IN org.apache.wicket.RequestCycle.processEventsAndRespond() ===
--processor.processEvents(this);
 UserActivationPage is constructed, and the page activates the user
 UserActivationPage does: setResponsePage(LoginPage.class);
--processor.respond(this);
LoginPage is constructed (messages exists in session and are 
properly rendered to somewhere)
===
[I can see in firebug that the correct response reaches the browser!]

	Strangely, In the page, wicket adds: 
	]]>*/

[So a new request is made!]
___
GET 
/ua?wicket:bookmarkablePage=wicket-6:ar.com.getsense.latamvalley.pages.LoginPage
 HTTP/1.1
Host: localhost:8080
...
Connection: keep-alive
Referer: http://localhost:8080/ua?ua=2e129db15b6d6db5342ba5d328642262
Cookie: JSESSIONID=78ehtk0o3y0w

=== IN org.apache.wicket.RequestCycle.processEventsAndRespond() ===
--processor.processEvents(this);
 LoginPage is constructed (not UserActivationPage like it did 
before) (this time, messages from the session are gonne)
--processor.respond(this); finally this page is shown without my 
messages :(
===

Thanks in advance,


Esteban

Re: Too Many Files Wicket 1.4.1

[Igor Vaynberg]

when you are requesting an embedded resource wicket needs to stream
the file out of a jar, the way the jvm handles that is by creating a
jar url connection object that streams the file. unfortunately, there
is a bug in the jdk where the url connection does not have a close
method and so wicket or any other java app cannot release the
connection. this is addressed, afair, in jdk 7.

i have many apps deployed in production and have not managed yet to
run out of the handles with the limit set about 4K. not sure why this
is different in your case. you mentioned "tests", are those unit tests
and is wicket there running in deployment mode?

the resource watcher, which should be disabled, will cause the handles
to run out because it continuously monitors markup files for changes
(hot reloading in dev mode) and everytime it checks a markup file in a
jar it creates the url connection and leaks it. by default it is
disabled in deployment mode but if you manually set the poll frequency
in your settings it will be reenabled.

Re: Page instantiated twice

[Igor Vaynberg]

are you opening the page in a new tab? this script is part of wicket
auto-multi-window support, it detects if the page has been opened in a
new tab and redirects to a url that will point to the same page but in
a new pagemap.

 Have you followed the suggestions in this thread?

 First, put a breakpoint to see what's instantiating the page - the  most
 likely suspect for an unintended additional instantiation is a bad
  link,
 something like: new PageLink(new MyPage());   <--- shouldn't do that

 If it's Wicket code, what code is it?  Why?  It might be statele

Re: Too Many Files Wicket 1.4.1

[Adam Bender]

Thanks for the explanation I think that helps shed some light... The  
tests are actually JMeter tests driving load by emulating a web  
browser - the application the are testing is running in Deployment  
mode set up as though it were a production server. After a little more  
digging I have been able to determine that is only a problem on pages  
which use Ajax - and it looks like there is a related debug message  
coming from an exception handler regarding the wicket-event.js file  
not being accessible (URI is not hierarchical). This would actually  
explain  why the problem only manifests when the JMeter tests are set  
to request embedded assets as wicket ajax pages embed requests for  
additional pieces of javascript - which in the case of wicket-event.js  
are causing exceptions to be thrown and the JVM bug you mentioned is  
probably preventing these resources from being cleaned up properly.


Does that sound right?

Hi,

we also had this issue, because (I think) we are running two

that we are running now the glassfish domains with custom init

with ulimit settings. Maybe this will help for you.

is
even weirder because our app serves these static items from httpd
without

embedded items

really affect the number of file handles wicket needs?

For completeness we are running this app on Red Hat Enterprise

with
Tomcat 6.0.20 and Java 1.6
