Why isn't _ available in the tree tag?

The workaround is to wrap it in a <dtml-let posting = "_.getitem('sequence-item',0)">

But now I'm confused.

Surely

<dtml-in postingValues> <dtml-let posting="_.getitem('sequence-item',0)"> <dtml-tree posting branches="postingValues"> <dtml-var id><BR> </dtml-tree> </dtml-let> </dtml-in>

should produce the same results as:

<dtml-tree branches="postingValues"> <dtml-var id><BR> </dtml-tree>

It doesn't :(

A guess (I never quite understood this either) Isn't the difference : - first example the 'postingValues' in the context of your 'posting' object and - the second the 'postingValues' in the context of the default objectlist - presumably objectValues

Why am I doing this you may ask? Well, I want to do batching at the top level and, AFAIK, dtml-in doesn't support this :(

any ideas?

if so, you might want to wrap the postingValues as well in a <dtml-let postings="postingValues"> just guessing Rik
