HtmlCommandLink ActionListener throwing Exception
I'm trying to dynamically building a list of links whereas each of them
has an ActionListener.
The code is like this:
while(...) {
HtmlCommandLink link = new HtmlCommandLink();
link.setValue("link text");
link.addActionListener(new PropertyPageListener());
panel.getChildren().add(link);
}
(PropertyPageListener is implementing the ActionListener interface)
The code is generating the links but when I click on one of them an
exception is thrown (see bottom of the mail).
Any idea what's going wrong?
Is is correct to call the method addActionListener with an anonymous object?

i thought i could use the method addActionListener... but
setActionListener isn't working either.
it seems as if the error is not dependent of the actionListener but
thrown if an HtmlOutputLink is clicked itself.... i just described the
problem in another mail...

setActionListener takes a MethodBinding which references an
ActionListener, and not an ActionListener directly. Create a custom
MethodBinding pointing to your PropertyPageListener.
I think I made an example of doing this as an attachment to
