You'll find two different methods to load tree content while opening its nodes, with examples. I personally suggest you the second one (Alternative Tree2 Lazy Loading Method...by jtmille3). Cosma 2006/6/5, Todd Patrick <[EMAIL PROTECTED]>:
I looked in the mailing list archive, there are a lot of discussions, but there are no examples. The closest discussion is listed below between Sean and Stefan back on Nov 22, 2005. Honestly, I haven't found one example. I'd appreciate any thoughts or pointers, whatever at this point. Thanks, --Todd "Please post your MyFaces questions to the user list. There are lots of people who can help you with this issue there. sean ---------- Forwarded message ---------- From: Stefan Vargocko <[EMAIL PROTECTED]> Date: Nov 22, 2005 3:28 AM Subject: Changing content of the tree2 To: [EMAIL PROTECTED] Hi Sean, I am using tree2. I am very satisfied with it, it's very nice and allows a lot of control. But I have one problem. I want to change content of the tree when some node is expanded. In general, I want to load children for node which should be expanded (so there is a click on a "+"). Is there any possibility to do this? Thank You for help.
