Hi,

I have an ultratree in FreeForm view style and each node has a columnset.

I have a hierarchy of several nodes, each being a child of the other. If i try to do a CollapseAll on a parent

node, it shows the plus sign for each node to indicate that it has been collapsed, but it doesn't hide the

child nodes (see fig1). If I then try to expand one of those nodes,  it sometimes crashes the treeview. 

Other times it expands as it fig2, but if I select one of these nodes, it crashes with :

************** Exception Text **************
System.ArgumentException: Item has already been added. Key in dictionary: 'Comparitor Not Set = Regular Expression Not Set'  Key being added: 'Comparitor Not Set = Regular Expression Not Set'

Also, doing ExpandAll more than once on a node sometimes expands it twice messing up the treeview, and sometimes gives the crash above.
