Hi, I have a tree node filtering function: ################# root = context.pres_docs_core_files obs = root.objectValues() for ob in obs: if ob.getId() == 'examples' : obs.remove(ob) return obs ################## When I am testing this PyScript it does its work pretty quickly. But when I call it from the dtml-tree tag, it just takes forever to render the tree. It does render it but it takes of the order of 20-25 seconds to do it. Any ideas why?? Also if any one can tell me a better way of implementing the above function (I have no idea how to use a lambda style function or a list mapping function in Python) that would be great...
