Andrea Del Bene created WICKET-4577:
---------------------------------------
Summary: Page version not incremented modifying page components
hierarchy
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
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.
