Re: Cache oddity ... maybe
I have briefly looked at ur codes. Have u checked if your code has not executed the refresh / reload routine? Some methods are not executed in AJAX. Sorry I can't tell u what methods offhand. If you placed your code in those methods then ur new items will not be loaded but it will when u do a page refresh. This has happened to me before. -- View this message in context: http://www.nabble.com/Cache-oddity-...-maybe-tp22889814p22983675.html Sent from the Wicket - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
Re: GWT vs. Wicket?
I really like the idea behind GWT. And striving for a statically typed 'true' OO programming model is what GWT and Wicket have in common. I haven't build anything with GWT, so my opinions in this respect are what I infer from how I think GWT works. I expect GWT to scale more easily if you plan well for it. Meaning that you probably don't want to end up with a very crowded pages that's very chatty with the server.. in that case Wicket might actually be more efficient (probably a surprise for many) because often times it'll do everything in one request (locality). A few other things I like about Wicket when compared with GWT: - It's just the Java code you work with, nothing complicating like an extra compile step (in GWT's case to JavaScript) or even byte code engineering like many other frameworks do. This makes Wicket easier to debug - though admitted Wicket doesn't have the easiest to follow bowels around due to the magic we have to do to give users a stateful programing experience. - Wicket is very flexible. I've read comments a while back of someone saying Wicket doesn't very well support integrating with other libraries... well, that's just bullocks. Some things will be harder than other things, but you can pretty much take the framework apart at any level and replace with your own ideas, including tags that dynamically create components and stuff. - Wicket is completely dynamic. I've worked on several projects now where we had panels contributed by e.g. domain objects. Maybe not something that appeals to people who take separation of layers ultra serious, but I think it is awesome. I currently use this for functionality that is about surveys. Surveys have questions, and these questions can be anything... free text, multiple choice, but potentially location or color. Questions can contribute their own panels for editing and viewing. So we can decide at some point to e.g. develop a location question, that displays a map, and we could jar the question with the UI with it, plug it in, and no-one ever had to touch other parts of the UI. I love that kind of flexiblity, and it's hard to find frameworks that support stuff like that (though I expect that you can achieve something like this with GWT, I don't expect it to be as straightforward as with Wicket). - It's safe by default. I don't mean hacker-safe, but rather that you never by default communicate sensitive info like IDs (or as with GWT whole objects) with clients. My experience with using other frameworks than Wicket is that we always spent quite a bit of time making sure users couldn't do things they weren't supposed to do (like deleting an object they have no right for), whereas with Wicket based projects the amount of time doing this is zero. I do expect a few things to be nicer with GWT though. Mainly, no worries about scaling (Wicket *is* scalable, but beyond a few servers you'll have to do work for it, while with GWT it's mainly a question of scaling your services and avoid too much chatty-ness), and no worries about detaching models! And these two advantages can be large enough for someone to prefer GWT. I can easily make this email 3 times longer with my perceived pros and cons, but these are the things that spontaneously came up. :-) Eelco On Wed, Apr 8, 2009 at 6:11 AM, Casper Bang cas...@jbr.dk wrote: I was just wondering about the Wicket community's opinion of GWT.

Re: Can client cache pages effectively?
Still sounds like you're jumping through hoops to force this HTML caching to fit - possibly opening up security vulnerabilities by exposing a user's role in the URL - which should only be in the session. I maintain that you'd be better off caching the data - that's the expensive part anyway. But it's your app and that's my two cents. :) -- Jeremy Thomerson http://www.wickettraining.com On Thu, Apr 9, 2009 at 11:29 AM, Jim Pinkham pinkh...@gmail.com wrote: 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.

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.

Re: Package all CSS and JS
I think that this response by Igor to another thread was supposed to be on this one. Either way, it fits this one. it is much simpler and more efficient to set proper caching headers. concatenating resources often does not work because different components on different pages contribute different resources, so there are a lot of variations of these huge files you may end up with and would have to stream to the user over and over. yes, it would only be one request per page, but it would be a huge one over and over as opposed to being able to cache a lot of small resources and never request them again. -igor -- Jeremy Thomerson http://www.wickettraining.com On Thu, Apr 9, 2009 at 9:06 AM, Eduardo Nunes esnu...@gmail.com wrote: Hi, Is there a way to tell wicket to package all referenced javascripts together, the same for the css?

Re: Package all CSS and JS
The problem with merging css is that the backgrounds will not work anymore (in case the images are referenced relatively). But there is a solution for this, check web resource optimizer ( http://code.google.com/p/wro4j/ wro4j ). It performs url rewriting. Also, resources can be located anywhere (classpath, disk, relative or absolute url, etc.). Alex Bjoern Tietjens wrote: Hi, how about doing this with some kind of precompilation step?

Re: Just showing rating results
It shouldn't be too hard to write one. It would just be a component that
shows an image then. The html would be something like this:
html
body
wicket:panel
img wicket:id=rating/
/wicket:panel
/body
/html
And the java file would be something like this:
public class RatingPanel extends Panel {
public RatingPanel (final String id) {
super(id);
String imageName;
// get rating
int rating = ...;
imageName = rating+rating+.png;
add(new Image(rating, imageName));
}
}
Mind you, I didn't test this or anything and it could be done a whole
lot prettier.

RE: How to manipulate an AjaxRequest
Hi Martin,
we have an solution, thanks for your help. Sort like your proposal. But an
command that has to be executed.
This command will force to do the data manipulation before any markup changes.
So markup changes won't be done if data manipulation gives exception. See
example under:
public void execute(AjaxRequestTarget target) {
try{
executeAction(target); -- Do data manipulation here
onActionSuccess(target);
} catch(Exception e) {
onActionFailure(target);
}
}

It could work, but that's not what I want, because also after the exception
is thrown components could be added to the target.
In that case I've to check on every add to target if an exception has
occurred. I prefer to do this on one place.
Maybe your exception handling could deal with this?
Would you like to show your code in order for us to have a closer view

Wicket in Action vs the other main books
Hello Wicketers, I am in the throes of a decision to buy the Wicket in Action book. There are a couple of other books but the little time I have lurked on this ML I have noticed the Wicket-in-Action authors are fielding some of the issues on this list. The reason I need to hit Wicket as hard as I can is I have already dismissed 3 other MVC frameworks that I have evaluated over the past two weeks. I have also evaluated 3 end-to-end MVC frameworks based on Wicket. End-to-end means: (HTML UI)(Java POJO middleware)(Hibernate|iBatis)(MySQL). I have dismissed all of the so-called end-to-end MVC frameworks except: databinder.net. The databinder.net framework is a great piece of software based entirely on Wicket and Hibernate. The only caveat is databinder.net appears to no longer enjoy a community type support. And, in fact, databinder.net does not seem to be supported in any way including the original author. So, betting the farm on databinder.net is problematic and this brings us to the question of: does the Wicket in Action book (or any Wicket book) discuss the coupling together of Wicket and something like Hibernate or iBatis to a restructured database for the purposes of rewriting an existing web app. The current web app run-time for the company I am working for was written using a code-generator. The name of the code-generator referenced in the previous sentence is not known. The original programmer that authored the original run-time web app has flown-the-coop. Rants and Raves welcomed.

David, Wicket in Action describe how to integrate with Spring and Hibernate. Databinder.net is LGPL, you can choose and copy code you like.

URL rewriting
We are evaluating wicket to rewrite our consumer UI. There is one requirement in which I would like to get advice on. We have a requirement in which the wildcard url gets dispatched to a controller that renders a page. The url pattern is in the form of /company/**-details.html. We have a single controller that receives the above url and figures out the company name and displays the page accordingly or throws a http 404 error if the company is not found. e.g /company/ABC-details.html, /company/TOTO-details.html etc Can this be done in wicket?

Re: Wicket in Action vs the other main books
You probably shouldn't base your evaluation of a book on how good any specific topic is explained there, unless this specific topic is one and the only thing you are interested in. You will most probably still have to spend some time researching whatever you're insterested in on the web. Still, Wicket in Action is afaik the most recent piece, and certainly comes from the most experienced in Wicket authors, which is good regardless of what solutions you're going to use for your business layer.

Re: wicket:Interface TabbedPanel and INewBrowserWindowListener
that parameter is only added when wicket thinks you opened a new browser window or tab. it has nothing to do with tabbed panel. have you done that? this code is based on window.name attribute so if you have some js that changes the value it may confuse wicket. -igor On Fri, Apr 10, 2009 at 8:38 AM, Daniele Dellafiore ilde...@gmail.com wrote: Hi everyone, I have this situation: a TabbedPanel with 2 panels each containing a form. Each panel have aa checkbox that trigger the enable/disable status of each component of the form. So I enter the panel, click the enable checkbox and then I can edit and save and press a discard button. The discard button execute a: setResponsePage(getPage().getClass(), getPage().getPageParameters()); becouse I need to reload the same entity I was editing and tipically I have a single parameters that is the ID of the entity. The effect is that the page is still in the initial situation, with editing disabled and every modification, of course, has not been saved. This works in the first Tab of the TabbedPanel. In the second, what happens is that fields values are reset but they do not go back to disabled status. The reason I think is that instead of just the entity ID I also found this pageParameter: wicket:interface = wicket-7:0:7:INewBrowserWindowListener:: I am pretty sure that is related to the TabbedPanel but cannot understand how. If I remove that parameter, the behavior is what expected: page is restarted and I am back to the first tab with fields disabled. Two question: 1. when and why that parameter is added? I would like to read more about wicket:interface and friends, can you point me to some doc? 2. What if I would like to reload the page on the same tab I was before? You think is better to call a setSelectedTab before the setResponsePage or to pass a pageParameter with the number of the selected tab? Or what else?

Re: URL rewriting
You have to mount your page via MixedParamUrlCodingStrategy:
mount(new MixedParamUrlCodingStrategy(/company, CompanyPage.class, new
String[] {companyName});
and in CompanyPage(PageParameters parameters) constructor do something like
this:
String nameInUrl = parameters.getString();
String company = nameInUrl.substring(0, ...);

2009/4/10 Craig Tataryn crai...@tataryn.net:
I have a component I'm designing where it displays a list of items to the
user, so the setup for the component on the page might look like this:
add(new MultiTextInputCollectionString(tags, new
ArrayListString() {
{
add(apple);
add(banana);
}
}));
The widget will render two sets of hidden inputs, one for the
original/additional items (name=tags) which were entered and one for
deleted items (name=removed_tags).
For instance:
input type=hidden name=tags value=apple/
input type=hidden name=tags value=peach/
input type=hidden name=tags value=grape/
input type=hidden name=removed_tags value=banana/
The above would result from me keeping apple and adding peach, grape, and
removing banana.
I'm a bit stuck on how I should get my component to put these values back
into it's model? Obviously in behind the scenes I'm going to have to do
some stuff in the MultiTextInput ctor to have the incoming Collection added
to a composite model that contains both the original/added items and the
removed items.
I'm just not sure where I broker the form submittal so that I have a chance
to move the tags and removed_tags into the proper place in the model for
my component. When the user calls getModelObject() on my component they'll
get an object back where they can query model.getItems() and
model.getRemovedItems().
As always, any help greatly appreciated!

It's an existing javascript widget I wrote so I was looking for a
quick port to Wicket. However there is no reason there couldn't be two
versions, the Ajax version could redraw everything serverside upon
addition/deletion of items.
So if it's possible for me to (easily) map those two sets of hidden
inputs to my model upon form submit I'd really like to know how.

I need image path in my java script , I want collapsable behavior
for my component , to which i add either plus or minus , when user
click on the imaghe my java script get the image with component and
checks the src to find if it is plus or minus , and finally changes
the image to the oppsite here is my java script
[code]
$(document).ready(function(){
$(p.collapsible_text).click(
function () {
var $img=
$(this).children(img);
var $div= $(this).next(div);
var
$label=$(this).children(label);
var imgSrc=$img.attr(src);
if($img.attr(src) ==
resources/gov.hhs.acf.web.pages.common.collapsable.AbstractCollapsablePanel/plus.png){
$div.slideDown(fast);
$label.html(Close);
$img.attr(src,resources/gov.hhs.acf.web.pages.common.collapsable.AbstractCollapsablePanel/minus.png);
return;
}
if($img.attr(src) ==
resources/gov.hhs.acf.web.pages.common.collapsable.AbstractCollapsablePanel/minus.png){
$div.slideUp(fast);
$label.html(Open);
$img.attr(src,resources/gov.hhs.acf.web.pages.common.collapsable.AbstractCollapsablePanel/plus.png)
}
}
);
});
[code]
now the problem is I hardcoded the image path in java script but
the image path changes becasue this sciprt gets added by my
collapsable panel and any page from any directory might use this panel
so the image path is different to different pages so need suggestions
on how to hard code image path in this java script

Wicket And Double Form Submission
Hi, I was just wondering how you guys implement double posting (double form Submission) measures for wicket. I was able to implement client side protection and was wondering if there any way to do it via server side also Is there one like struts token approach that I can use? What is the best way to do this? Thanks Carlo

The wicket requestCycle redirects by default, you can put a brekpoint at
public final void setRedirect(final boolean redirect)
{
this.redirect = redirect;
}
and you'll see.
Ofcourse the http traffic is more efficient if you avoid double
submission on client side and just 'gracefully' (more or less,
depending on your service) fail on server side on double submit.

Re: Wicket And Double Form Submission
ya i tested it on indicatingajaxbutton.
seems that when you don't enable javascripts, you don't go to the event
handler for
your button.
Instead the page is reloaded again
so if i'm able to catch it on the client side with javascript turned on, it
wouldn't anymore be a problem. hopefully :P

Re: image path for my java script
the easiest way to deal with images is to always use css, that way
images are always loaded relative to css and you dont have a problem.
instead of an img tag add a div class=plus and have div.plus {
background: url('plus.gif'); width:20px;height:20px; }
other then that you can always build a url using urlfor() methods on
component and request cycle and pas those as parameters to your
script.

Re: Component Model question
look at textfield.
all you have to do is to write out the input tags with a name you
obtain from formcomponent.getname() - to guarantee uniqueness, then
override convertinput() and pull those values out of the request into
a collection and call setconvertedinput(collection). formcomponent
will take care of everything else such as validation and updating the
model. thats all there is to it.

I have a component I'm designing where it displays a list of items to the

add(new MultiTextInputCollectionString(tags, new

add(banana);
}
}));
The widget will render two sets of hidden inputs, one for the
original/additional items (name=tags) which were entered and one for
deleted items (name=removed_tags).
For instance:
input type=hidden name=tags value=apple/
input type=hidden name=tags value=peach/
input type=hidden name=tags value=grape/
input type=hidden name=removed_tags value=banana/
The above would result from me keeping apple and adding peach, grape, and
removing banana.
I'm a bit stuck on how I should get my component to put these values back
into it's model? Obviously in behind the scenes I'm going to have to do
some stuff in the MultiTextInput ctor to have the incoming Collection added
to a composite model that contains both the original/added items and the
removed items.
I'm just not sure where I broker the form submittal so that I have a chance
to move the tags and removed_tags into the proper place in the model for
my component. When the user calls getModelObject() on my component they'll
get an object back where they can query model.getItems() and
model.getRemovedItems().
As always, any help greatly appreciated!

Re: Package all CSS and JS
my point is that the just in time thing will not work suppose on page A you use jquery and ext on page B you use jquery and yui using this just-in-time composition you will get two resources: jquery+ext and jquery+yui - so you are trading 3 hits for two hits, but transferring jquery twice. even worse, consider on page B you have a dynamic header contributor that sometimes adds mootools. so now you have jquery+ext, jquery+yui, jquery+yui+mootools, in the case of the latter you did not actually save a request to the server because you still have the jquery+yui+mootools combo, but because you are doing this caching the last request which was supposed to be just for mootols now also has to carry jquery+yui. wicket is very dynamic, which makes these kinds of page-oriented caching strategies difficult. in order to work correctly everything should be oriented around a component, not a page. -igor On Fri, Apr 10, 2009 at 1:44 PM, Brill Pappin br...@pappin.ca wrote: Yah, he's right about the caching... so maybe not work it... however the solution someone posted was a ... hmm...

Either way, it fits this one. it is much simpler and more efficient to set proper caching headers. concatenating resources often does not work because different components on different pages contribute different resources, so there are a lot of variations of these huge files you may end up with and would have to stream to the user over and over. yes, it would only be one request per page, but it would be a huge one over and over as opposed to being able to cache a lot of small resources and never request them again. -igor -- Jeremy Thomerson http://www.wickettraining.com On Thu, Apr 9, 2009 at 9:06 AM, Eduardo Nunes esnu...@gmail.com wrote: Hi, Is there a way to tell wicket to package all referenced javascripts together, the same for the css?

Betreff: Re: Montable PDF creating page
why would you want a mounted page to create pdfs? servlets are so much
better at that.
that said you can do
getrequestcycle().setrequesttarget(new sometargetthatstreamspdfs());
throw new restartresponseexception();

I need some trick to turn the response into a PDF stream. E. g. I have a

public class PdfPage extends WebPage {
public PdfPage (final PageParameters parameters) {

}
Application.init() {
mountBookmarkablePage(/PdfGenerator, PdfPage.class);
Is it possible to let a WebPage create a pdfOutput? If I try to do the
following
Response r = getResponse();
if (r instanceof WebResponse) {
WebResponse wr = (WebResponse)r;
wr.reset();
OutputStream os = wr.getOutputStream();
try {
os.write(/*PDFcontent*/);
} catch (Exception e) {
e.printStackTrace();
}
}
}
I can see the Exception java.lang.IllegalStateException:
getOutputStream() has already been called for this response
The reason for this is: I did not find something like
BookmarkableResource in wicket. It is no problem to have a
DynaicResourceLink in a page but the displayes content is not
bookmarkable. Any Ideas?

RE: debugging a Wicket application running under Jetty-6.1 in Eclipse
It is working now. I am debugging in Eclipse. Thanks a lot -Original Message- From: jcgarciam [mailto:jcgarc...@gmail.com] Sent: Thursday, April 09, 2009 6:06 PM To: users@wicket.apache.org Subject: Re: debugging a Wicket application running under Jetty-6.1 in Eclipse I'll suggest to do it in the Wicket Way, you will have much more benefits. If you made your project from the QuickStart, you will notice a 'Start' class under your 'test' source. that what it does is just start an embedded jetty pointing to your webapp directory and mounting your application under / context. so just right click on it and click Debug as - Java Application and you're done. Even if you are working on a multi-module maven project this will work, just make sure your module are installed on your local repository, issuing 'mvn install' on the root project. If you have question regarding the 'Start.java' class just let us know. mchenini wrote: Hi, This is about debugging a Wicket application running under Jetty-6.1 in Eclipse.

The steps I followed are: Step 1 Go to the Run/External Tools/External Tools ... menu item on the Run menu bar. Select Program and click the New button. On the Main tab, fill in the Location: as the full path to your mvn executable. C:\java\DEVTOOLS\MAIN\maven2\bin For the Working Directory: select the workspace that matches your webapp. For Arguments: add jetty:run. Move to the Environment tab and click the New button to add a new variable named MAVEN_OPTS with the value: -Xdebug -Xnoagent -Djava.compiler=NONE -Xrunjdwp:transport=dt_socket,address=4000,server=y,suspend=y If you supply suspend=n instead of suspend=y you can start immediately without running the debugger and launch the debugger at anytime you really wish to debug. Step 2 Then, pull up the Run/Debug/Debug ... menu item and select Remote Java Application and click the New button. Fill in the dialog by selecting your webapp project for the Project: field, and ensure you are using the same port number as you specified in the address= property above. Now all you need to do is to Run/External Tools and select the name of the maven tool setup you created in step 1 to start the plugin and then Run/Debug and select the name of the debug setup you setup in step2.

Thanks Igor, in my version I had overridden updateModel like so to get
it working:
public void updateModel() {
String[] added = this.getInputAsArray();
String[] removed = getRequest().getParameters(removed_ +
getInputName());
MultiTextInputModel model = (MultiTextInputModel)
this.getModel();
model.setItems(added == null ? EMPTY_STRING_COL :

model.setRemovedItems(removed == null ? EMPTY_STRING_COL :

I'm assuming that convertInput fires before update model, so I should
override that method as you suggest to handle different types but
maintain my updateModel as well to shovel things into the right places
in the model?

Re: Component Model question
no, all you have to do is override convertinput and inside call
setconvertedinput(yourcollection);
the default implementation of updatemodel() already does
getmodel().setobject(getconvertedinput());
