Playing devil's advocate here: so what's the point/benefit of preventing a call to setEnabled() if one can override isEnabled and "modify the hierarchy" beyind Wicket's back anyway?
I personally prefer explicit calls to setEnabled() from onRender() than subclassing because it allows me to know upfront exactly where its value is being changed (plus you don't have to recalculate the value if it hasn't been changed).

Just override isEnabled. That's why it's not final. Eelco On 3/15/06, David Leangen <[EMAIL PROTECTED]> wrote:This approach used to work for me under 1.1, but no longer in 1.2. I have a BookmarkablePageLink that I want to disable when its target is a subclass of a given page. I used to do something like this: protected void onRender( final MarkupStream markupStream ) { setEnabled( ! m_parentClass.isAssignableFrom( getPage().getClass() ) ); super.onRender( markupStream ); } But this now throws an exception: wicket.WicketRuntimeException: Cannot modify component hierarchy during render phase at wicket.Page.checkHierarchyChange(Page.java:1001) at wicket.Page.componentStateChanging(Page.java:934) at wicket.Component.addStateChange(Component.java:2118) at wicket.Component.setEnabled(Component.java:1732) ... How should I go about creating the same effect? Where should I set the link's enabled value based on the above criterion? Thanks!
