[jQuery] (treeview) Need help with Treeview pre-1.4.1 and jquery.treeview.edit

Hello,
at first I can say that Treeview is a great jQuery plugin!
I use the plugin a lot and have some questions now.
I found a newer Version "pre-1.4.1" here:
http://view.jquery.com/trunk/plugins/treeview/jquery.treeview.js
Demo: http://view.jquery.com/trunk/plugins/treeview/demo/
Is this version still in development?
Very interesting in this version is the possibility to add and remove
a node. These features was added in the file jquery.treeview.edit.js:
http://view.jquery.com/trunk/plugins/treeview/jquery.treeview.edit.js
There are still some bugs here, e.g.:
- go to the test-page: http://view.jquery.com/trunk/plugins/treeview/demo/edit.html
- first, delete "File 4"
- then, delete "File 3.1"
- now, the icon in front of "Folder 3
closed at start
" is not
correct
The good news: I found the bug, here is the new working code for
"jquery.treeview.edit.js", please replace the old code:
if
parent.is
":not
:has
