Retrieving the submit button value
Hi, i'm trying to migrate my application wicket 1.4 to 6.13 and my earlier code has this code snippet to get the button value. frm.getRootForm().findSubmittingButton().getInputName(); but this is not possible with 6.13. is there a way to get the submit buttons value for comparison.

Re: Retrieving the submit button value
Thanks martin. It fixed the compilation issues for me. should try out deploying the artifact. -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/Retrieving-the-submit-button-value-tp4664137p4664139.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

Hi,
Create a panel that has a child an image (the busy indicator).
Add a timer behavior to this panel and check whether the slow operation is
done and replace the image with another component that renders the new
data:
public void onTimer(AjaxRequestTarget target) {
Data newData = getNewData();
if (newData != null)
{
NewComponent c = new Component(image.getId(), newData);
image.replaceWith(c);
target.add(c);
}
else {
// target.appendJavaScript(still waiting ...);

Thanks Martin!
This pattern seems very similar to
https://gist.github.com/jonnywray/594468 and
https://gist.github.com/jonnywray/636875
which I have seen referenced in some posts here.
While trying these, I am finding in FutureUpdateBehavior, onTimer(), the
line if(future.isDone()) is null most times (not all).
I am not quite sure why this would be.
When it is null, the constructor value passed through is not null, but is
null within onTimer.
Any ideas on this?

Re: AjaxLazyLoadPanel loading asynchronously
Because it is transient:
https://gist.github.com/jonnywray/636875#file-futureupdatebehavior-java-L19
After deserialization it will be null.

Accessing WebApplication from the service layer
Hey,
I've just been sketching out an entity locking mechanism (below) to prevent
users from editing entities which another user is already in the process of
editing. It works fine but the problem is that placing this in my
WebApplication class means that I need to make MyApplication.get() call from
within my service layer and this seems a tad messy. Is this a Wicket
cardinal sin or am I just stressing over nothing?
Cheers,
Chambre

Re: Accessing WebApplication from the service layer
Hi,
Extract the locking managing code in a service.
Then use Spring/CDI/Guice/... to manage the service dependencies for you.

Re: Accessing WebApplication from the service layer
Well, you can either store it as application metadata or make your locking service implementation a singleton (managed by your dependency injection framework of choice). Either way, you abstract away the exact storage location of your locks behind the facade of your EntityLockingService.

Re: Accessing WebApplication from the service layer
Yes however I also store the id of the session that owns the lock in a map so that I can easily flush locks when a user session expires. This would mean that EntityLockService would need access to the current WebSession which also seems messy...

Re: AjaxLazyLoadPanel loading asynchronously
Hi, When your page gets serialized (which can happen between requests), transient fields (like the future field) are set to null. When your behavior is triggered and the page is deserialized, the field is null.
