Re: wicket bench in eclipse
I had not heard of wicket bench before reading this email thread. So, I installed it and found that it doesn't play well with 'myeclipse'; not sure where the fault lies. So I just don't use it as a default editor. I do like some of the features. If you just want to switch between java and html use 'alt + leftarrow' and 'alt + rightarrow'. This switches between recently edited files. On Wed, Jan 27, 2010 at 1:06 AM, Lionel Port lionel.p...@gmail.com wrote: Agree with Huake Ingmar. The functionality doesn't overlap at all. My main reason for wanting the plugin to work is to switch easily between the html and the java code for the same component.

Re: Cannot get default invisible TextField's ModelObject ?
I looked some more and found the following:
When it works, with my modification, FormComponent.getInputAsArray tries to
get parameters for the TextField named more:moreForm:textfield. I looked
in the parameter map or the RequestFacade object and found these:
wicket:interface, wicket:ignoreIfNotActive, random, more:moreForm:textfield,
radioGroup and more:moreForm:submit. And it finds the TextField.
The version that fails is looking for TextField named more:textfield. The
RequestFacade object has: wicket:interface, wicket:ignoreIfNotActive,
random, forma_hf_0, radioGroup and more:submit. Is there a problem with
forma_hf_0?

If the form is not inside a ListView , it will work.
But it just fails if it is inside a ListView.

Thanks for wicket: it is awesome and I'm just getting to know it
Just wanted to say thanks for wicket.
I have a ListMultipleChoice and wanted to update the page based on at least
one item selected or no items selected. It took a while for me to locate
lmc.add(new AjaxFormComponentUpdatingBehavior(onChange) {
@Override
protected void onUpdate(AjaxRequestTarget target) {
// do the right thing here!
}
});
but once I did it just worked. I like things that just work. I don't know
js very well so just java and just html if real attractive to me.
Thanks again for wicket.

Re: page expired problem issue wicket how resolve fix eofexception peekbyte
Hi Martin, I'm new to wicket. Could this have something to do with wicket trying to restore a page from serialized data. If one of the objects on your page can not be serialized you will get an error when wicket tries to restore the page. I think you might see this when the back button is pressed. I think using a detachable model is one option if you use a 3rd party object that isn't serializable.. If you wrote the object you can make is serializable. Then again I could be all wrong.

Re: page expired problem issue wicket how resolve fix eofexception peekbyte
Martin, I don't know a good way. Do you know what page is causing the problem? Manually check each object in all components of the page. Once you know the page you can try removing components until the error goes away. Last one removed is the offender. There may be multiple offenders. Maybe not a good way. Get the source for wicket and modify org.apache.wicket.Component.readObject(Component.java:4465) to catch the exception. At this point you can either print the class of the object being read (some type of Component) or use the debugger (my preference). You might have to back up to org.apache.wicket.protocol. http.SecondLevelCacheSessionStore$SecondLevelCachePageMap.readObject(SecondLevelCacheSessionStore.java:417). This may be a bit of work and might not tell you anything. The up side is that you now have wicket source and can debug your next problem. I usually assume there will be another problem. I'm sure others reading along will have better ideas. Chuck On Tue, Jan 12, 2010 at 6:27 AM, Martin Asenov mase...@velti.com wrote: Hi Chuck, nice to read from you!

Re: page expired problem issue wicket how resolve fix eofexception peekbyte
Martin, I was not suggesting a permanent change to the framework. Just temporary while you debug the problem. I got the source, did mvn install, it generated the jar file which I then copied over to my project. If I can do it anyone can. The problem isn't in wicket but in your domain object(s). I'm out of ideas. Maybe someone from the wicket team has a good suggestion.

Last one removed is the offender. There may be multiple offenders. Maybe not a good way. Get the source for wicket and modify org.apache.wicket.Component.readObject(Component.java:4465) to catch the exception. At this point you can either print the class of the object being read (some type of Component) or use the debugger (my preference). You might have to back up to org.apache.wicket.protocol. http.SecondLevelCacheSessionStore$SecondLevelCachePageMap.readObject(SecondLevelCacheSessionStore.java:417). This may be a bit of work and might not tell you anything. The up side is that you now have wicket source and can debug your next problem. I usually assume there will be another problem. I'm sure others reading along will have better ideas. Chuck On Tue, Jan 12, 2010 at 6:27 AM, Martin Asenov mase...@velti.com wrote: Hi Chuck, nice to read from you! Yes, this could be all true, but I can't see anywhere in the logs comprehendible reports of what happens. Nothing says which is the problematic object, and I can only guess. Do you now a way to trace down where the problem comes from? Thank you! P.S. I'm new to Wicket too :) -Original Message- From: Chuck Brinkman [mailto:chasb1...@gmail.com] Sent: Tuesday, January 12, 2010 1:23 PM To: users@wicket.apache.org Subject: Re: page expired problem issue wicket how resolve fix eofexception peekbyte Hi Martin, I'm new to wicket. Could this have something to do with wicket trying to restore a page from serialized data. If one of the objects on your page can not be serialized you will get an error when wicket tries to restore the page. I think you might see this when the back button is pressed. I think using a detachable model is one option if you use a 3rd party object that isn't serializable.. If you wrote the object you can make is serializable. Then again I could be all wrong.

Can you tell me what this means The palette itself cannot be ajaxified because it is a panel and therefore does not receive any javascript events.? Would a palette without javascript require full page loads?

Re: how to change BookmarkablePageLink label
Thanks, I was thinking of the link as a single widget not a a link with a
label. This seems to work.
div id=logInOut name=logInOut
a href=# wicket:id=logInOutLinkspan
wicket:id=logInOutLabel/span/a
/div
if(UserHelper.get().isGuest(dis.getUser())) {
BookmarkablePageLink bpl = new
BookmarkablePageLink(logInOutLink , Login.class);
add(bpl) ;
bpl.add(new Label(logInOutLabel, Login));
} else {
BookmarkablePageLink bpl = new
BookmarkablePageLink(logInOutLink , Logout.class);
add(bpl) ;
bpl.add(new Label(logInOutLabel, Logout));

looking in the right place. Can someone show me the way. Thanks.

how to clear validation error
I have a form with a html submit button. In java I wrote my own onSubmit to handle the form processing. In the form I have a firstName field that is required. li First Name: span wicket:id=borderFirstName input type=text wicket:id=firstName/input /span /li TextField firstName = new TextField(firstName); firstName.setRequired(true); form.add( new FormComponentFeedbackBorder(borderFirstName).add( firstName ) ); All works great as long as the user input is valid. If I attempt to submit an empty firstName field I get the expected message in my FeedbackPanel and my firstName text field gets the red asterisk. I then add a valid firstName and submit again. The page remains showing the valid firstName input along with the validation errors and onSubmit does not fire. I must be doing something wrong but can't figure it out. Thanks for your help. I'm using wicket 1.4.5, tomcat 6, java 1.6 and firefox 3.0.8 on fc9.

Re: how to clear validation error
Thanks for your help but I don't understand. I even got the source code for http://www.wicket-library.com/wicket-examples/signin/?wicket:bookmarkablePage=:org.apache.wicket.examples.signin.SignInand when I run this in my environment I have the same issue I have with my code. Once I get a validation error onSubmit is never called even after the input error is fixed. This works fine when running at www.wicket-library.com. What should I do in the onError method to correct this situation? Sorry to be so lame and thanks for your help.
Re: how to clear validation error
I got the code for wicket 1.4.5 and stepped through to see what is causing the problem. Form.anyFormComponentError checks all the components on the form to see if 1) input is required and 2) is an error message exists for the component. It appears to me that once a message is set that it is never reset. I don't see how this could be working for others and not working for me. Any ideas? Is there some setup or configuration I'm missing that causes error messages to be cleared?

Re: how to clear validation error
The messages are kept in WebSession and WebSession has cleanupFeedbackMessages() but this is never called. Got it. The session I created had a empty cleanupFeedbackMessages() method.
