[Pharo-users] Gtoolkit and fast trees

Hi, I would like to understand the differences between tree and fastTree. I've got different behavior between tree and fastTree, the second failing with a subscript out of bounds. It happens when I expand the root node and select one of the children. .... it seems that the rootNode cannot find the children... (see below a screenshot). What is more strange is that using the same dataset sometimes it works as expected and sometimes not... I could not reproduce it in a short script (yet). Any pointer is welcome Thanks.
