I'm trying to use dtml-tree to create a selective menu of objects based on whether or not the object has an "add_to_menu" property. I've pretty much figured out that I need a wrapper around objectValues that will filter out the objects that don't have the "add_to_menu" property. This wrapper would be called with dtml-tree's "branches" attribute. I'm trying to do this wrapper in a DTML method and I've gotten all the way to where I have to return a list of "actual objects", so says the DTML Quick Reference.
Is there someone who could 'splain to me how to build a list of objects in DTMLese?
Here's what I have so far (obviously not working):
<dtml-call "REQUEST.set('ret', '')"> <dtml-in "objectValues()" sort=id> <dtml-if "_.has_key('add_to_menu')"> <dtml-call "REQUEST.set('ret', ret + ' ' + _['sequence-item'])"> </dtml-if> </dtml-in> <dtml-return "_.string.split(ret)"> That's perfect.
Almost surely, your problem results from the fact that "dtml-tree" does not expect "branches" to be a DTML method and does not pass a namespace to it. I do not know, how you can avoid this (other than changing the "dtml-tree" code. Dieter
