Re: Tree component not functions correctly

[Alex Harui]

Can you provide a sequence of steps to reproduce the problem? (click on “foo”, 
open “bar”, “close “bar”, …)

Thanks,

Subject: Tree component not functions correctly

Hi,

Before trying to fix tree in my project I checked the example in tourdeflex 
modules. I would like to learn if anyone has checked that example because I 
couldn't make it work.

It fails after some and open/close clicks. Some of the menu items disappear. I 
want to make it work before focusing on my own implementation.

Here is the code :
