Hi,
I'm trying to implement a pretty simple menu structure that supposed to update
the menu tree when a given link is clicked and also update the content of the
page. I've got it working but only for the first click...
First time I click on one of the given links the tree expands to show the sub
menu and the content div (main_content) updates to display the name of the link
that the user has selected. Problem is when I then click on another link
nothing happens. If I refresh the page then I can click on another link again.
Any ideas as to what I'm doing wrong?
Also for the EventListeners is there a neater way of working out which link has
been clicked rather than adding in all the elements to the EventListener
annotation? It's not really a sustainable solution once the menu structure gets
bigger. Ideally I'd want to pass through a parameter link you do with a regular
listener (e.g. the parameters definition on a DirectLink) but I can't see where
I could define this.
Relevant parts of html, page and java files are attached. I'm using the 4.1.1
snapshot on Tomcat 5.0.1.9 with Firefox.
Thanks,
Dom
