Andrea Del Bene commented on WICKET-4577:
-----------------------------------------
Is there any way to know if the current request has been triggered by a
ILinkListener or by a IFormSubmittingComponent? I mean, it would be nice if we
were able to not freeze page id if user has explicitly clicked on a link or on
a button.
This would solve both WICKET-4286 and the problem with back button. IMHO since
page versioning's main goal is to support back button, it would make perfect
sense if we create a new page version when user interacts with page (i.e. when
she clicks on a link or on a submit button) .

> Key: WICKET-4577
> URL: https://issues.apache.org/jira/browse/WICKET-4577
> Project: Wicket
> Issue Type: Bug
> Affects Versions: 1.5.6
> Reporter: Andrea Del Bene
> Attachments: LifeCycleStages.zip
>
>
> Starting from version 1.5.6 I started to notice a strange behavior with page
> versions management. Let's consider a simple page that displays alternatively
> two labels each time is rendered:
> public HomePage(){
> firstLabel = new Label("label", "First label");
> secondLabel = new Label("label", "Second label");
>
> add(firstLabel);
> add(new Link("reload"){
> @Override
> public void onClick() {
> }
> });
>
> }
>
> @Override
> protected void onBeforeRender() {
> super.onBeforeRender();
> if(contains(firstLabel, true))
> replace(secondLabel);
> else
> replace(firstLabel);
>
> }
> Until Wicket 1.5.5 the page id is incremented each time I reload the page,
> and this is the expected behavior. But with Wicket 1.5.6 this doesn't happen
> anymore and the version id remains unchanged when I reload the page. This
> breaks back button support and I doesn't seem correct since we should obtain
> a new page version when we change page components hierarchy.
> Quickstart attached.
