what i can do in onbeforerender to make the component 1's bind get called (in my case, the behavior contributes js and css to <head>)?

Re: When is AbstractBehavior#bind not called?
Posted by Igor Vaynberg <ig...@gmail.com>.
the first link is a bookmarkable link, it recreates the page instance.
bind is only called when the behavior is *added* to the component.
link 2 is not a bookmarkable link, it doesnt recreate the page
instance so the behavior is not added because a page instance where
the behavior has already been added is used, thus no bind call

When is AbstractBehavior#bind not called?
Posted by David Chang <da...@yahoo.com>.
I have a top page which has two panel-based components.
Component 1 implements AbstractBehavior's bind method.
Component 2 has a wicket Link pointing to a child page.
When I am at the top page, refresh always gets #bind called.
When I click the Link in Component 2, the bind method in Component 1 does not get called.
Can anybody tell why this happened?
I am quite puzzled. I am kind of new in wicket. I am using wicket 1.4.8 on tomcat.
Regards.

Re: Empty List Default Message
Posted by Pedro Santos <pe...@gmail.com>.
Hi, just an idea:
class EmptyMessage extends Label{
EmptyMessage(Model listModel, String message){
super(new AbstractReadyOnlyModel(){
getObject(){
listModel.getObject().size()==0?message:null;
}
});
}
}
