Hi, I have a problem with the tree tag. I want to show in the page a hierarchy with codes of a database. I've read in this page: http://www.zope.org/Members/anthony/tree-coding-tricks an example of how to do it but it doesn't work in my case. In the example Anthony creates this SQL method: SELECT objectid, objectname FROM myobjects WHERE <dtml-sqltest parentid type=int> and this is the code of the DTML Method: <dtml-let objectid="0"> <dtml-tree id=objectid branches_expr="child_lookup(parentid=objectid)"> <b><dtml-var objectname></b> <dtml-var objectid> </dtml-tree> </dtml-let> I have created an SQL method like in the example called lrecursos (which works properly), and this is my DTML Method: <dtml-let objectid="'0'"> <dtml-tree id=objectid branches_expr="lrecusos(codigo_recurso=objectid)"> <b><dtml-var codigo_recurso></b> </dtml-tree> </dtml-let> The problem is that it does not show the tree properly, it only shows the tree properly at the begining, when I want to expand the tree it shows in the next levels of the tree the elements that are at the highest level. What can I do? I think that the problem is that objectid does not change. bye, bye ...
