Hi, I've got <dtml-tree> which branches_expr calls a method which returns a list of mappings. e.g. : [ { 'name' : 'jerome', 'age' : 72 }, { 'name' : 'albert', 'age': 2}, ... ] now in the body of the tree tag, I want to access each mapping, i.e. push it onto the current namespace. I've tried to add the "mapping" keyword, which works fine for <dtml-in>, but with no luck. I wanted to use the _.namespace() method, but I can't access the tree's "pseudo-sequence-item". is there a solution ? if no, then could the 'mapping' keyword be added to the tree tag and let it work like for dtml-in ? (I've looked at the code but I really don't know how to do) Any help appreciated Thanks in advance Jerome Alet
