Developing custom component based on HtmlPopup

[innflow-guenther]

Hello,

I want to develop a component based on HtmlPopup. As a 
starter I just copied&pasted the HtmlPopup component code 
in my own component (later on I will try with just 
extending HtmlPopup if that is possible). But I receive 
"expected custom component class in package 
org.apache.myfaces.custom. Seems I have to implement an 
own ResourceHandler, is that right? Can you give me some 
hints how I can do that?

Thanks
René
