Hi,
I have found any subjects on this so..
I want to apply a text filter to leaves of a tree. All the branches
that do not have leaves after this filter must be hidden (for this i
apply another filter that tests the number of children each branch
still have).
It works as long as all the branches still have at least one item
displayed otherwise as soon as i try to expand/collapse a branch, this
error is generated:
TypeError: Error #1010: A term is undefined and has no properties.

Have u got any idea to avoid this error ? any help would be appreciated.
