Dtml-tree and manage_delObjects funny behavior Hi, I use dtml-tree to show a hierarchy of folders containing exclusively instances of, say,MyZClass. The user can use the tree structure to add and update MyZclass instances, which properties are set by acquisition. A funny thing happens when I try do delete an instance: the folder containing the instance "looses" the id showed on the tree (its path become something like 127.0.0.1/Cities//) and the actual object that I would like to delete is not destroyed at all! The codes are: The tree: <dtml-var standard_html_header> <dtml-tree Cities branches=objectValues sort=id> <img src="<dtml-var SCRIPT_NAME>/<dtml-var icon>"> <dtml-if "meta_type=='Folder'"> <dtml-var id> <a href="<dtml-var tree-item-url>/frmAdd"><+></a> -->adds instances of MyZclass in the folder <dtml-else> <a href="<dtml-var tree-item-url>"><dtml-var title></a> <a href="<dtml-var tree-item-url>/frmDelete"><-></a> -->deletes the current MyZclass instance </dtml-if> </dtml-tree> <dtml-var standard_html_footer> The "destroy" method (metDestroy): <dtml-call "manage_delObjects(['id'])"> <dtml-var id> ------->shows the desired id (the Zclass instance id) that method is called by a another method which asks for confirmation from the user (frmDelete): <dtml-var standard_html_header> <FORM action="metDestroy"> Are you sure?<br> "<dtml-var summary>"<br> -->only shows the object summary property <input type=submit value=" Remove? "> </form> <dtml-var standard_html_footer> When that strange behavior started, I wrote some code to show the actual "id" being used in <dtml-call "manage_delObjects(['id'])">, and it was the MyZclass instance id, so there is no problem with ids (I think!). I used this method as both a MyZclass method and as a method in my main folder (Cities). The behavior was the same... I had to delete the folder where I tried to delete the instance so that the tree could "remember" the real folder structure (that was not affected!) The folder structure is Cities City1 Category1 MyZclass1 MyZclass2 MyZclass3 ... Category2 MyZclass4 MyZclass5 MyZclass6 ... Category3 ... City2 ... City3 ... ... One more thing: how can I refresh the tree after deleting or adding an object? I mean, how can I redirect from the Add/Delete forms to the tree form and refresh the tree? Thanks in advance, Rogerio
