Re: DOM element not found issue - Ajax response
Hi, Are you blocking the UI during AJAX requests? I have seen similar weird things happening because: 1- One AJAX request (R1) is executing. 2- UI is not blocked. User click on on something. A second AJAX (R2) request is queue: as far as I understand AJAX request are queued by channel (please, Martin, correct me if I'm telling something wrong). 3- R1 completes and does some DOM replacements. 4- R1 is sent and after server response tries to do something on DOM but R1 already replaced that element. Try blocking the UI. On Fri, Apr 4, 2014 at 7:22 AM, Rakesh A iamrakes...@rediffmail.com wrote: Hi, In my case, the DOM element is not part of iframe/modal window, its in the current page itself.

You are correct, Ernesto ! :) By default all Ajax calls use the same channel name (0) and type (queue). You can control this by using custom AjaxChannel - AjaxRequestAttributes#setChannel(). 3- R1 completes and does some DOM replacements. 4- R1 is sent and after server response tries to do something on DOM but R1 already replaced that element.

FormComponentPanel.validate() API Doc question
Dear forum, I've written a FormComponentPanel in which one can select a date range and during validation I want to check that start date is not in the past or that end date is before start date. I have decided to do these checks by overriding FormComponentPanel.validate(). The FormComponentPanel.validate() API Documentation ends with *This method should only be used if the form component needs to be fully validated outside the form process.* What exactly does *validate a component outside the form process* mean? English is not my first language so maybe that's why I don't get it. All explanations will be much appreciated. Thanks in advance, Lucas -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/FormComponentPanel-validate-API-Doc-question-tp4665262.html Sent from the Users forum 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: FormComponentPanel.validate() API Doc question
Hi Lucas, #validate() is called by the Form when it processes a request. Usually you don't call this method by yourself - that's all. Overriding #validate() is OK. Note that a FormComponentPanel can have validators too, so it might be simpler to just add one for your date checks.

autocomplete + ajaxformcomponentupdate - mouseselection not working after error
Hi wicketusers,
I have an autocomplete textfield with an
AjaxFormComponentUpdatingBehavior attached for the 'change' event.
After an error on the input the update is handled in the onError
method -- ( some pseudocode )
autocompletefield.add(new AjaxFormComponentUpdatingBehavior(change) {
.
protected void onError(AjaxRequestTarget target,
RuntimeException re) {
autocompletefield.add(new
AttributeModifier(CLASS_ATTRIBUTE, AUTOCOMPLETE_INVALID_CLASS));
target.add(autocompletefield);
}
Here is the autocompletefield replaced by an updated version with a
new class attribute.
The problem is that a mouseselection of a listitem in the dropdown is
not selected. A mouseselection just closes the autocomplete window.
Selection with the keyboard works just fine.
Any suggestions how to tackle this problem?
Thanks in advance,
Haiko van der Schaaf

Hi,
Try to debug it.
Open wicket-autocomplete.js in the browser dev tools and see what happens.

Wicket CDI 1.1
Hi All I am in the process of moving my application to JavaEE7 and CDI 1.1. Things are going well all except for some CDI values. I have an @Stateless Session bean used for my DAO which I then Inject into various classes. The issue I have is that some of the classes don't get the reference Injected properly and give a NPE. With wicket CDI I was able to call CdiContainer.get().getNonContextualManager().inject(this); to Inject the reference properly. I know CDI 1.1 is different but I can't work out how to Inject the Component with Wicket CDI 1.1? Here is the code in my WicketApplication init(): new CdiConfiguration().setPropagation(NONE).configure(this); Thanks David
