[Zope] Peculiar effects with SQL tree

[Stephen Harrison]

I have a dtml-tree which is getting its tree data from an sql method:

<dtml-let oid="0">
 <dtml-tree id='oid' 
branches_expr="sqlSelect_treeParent(parent_id=oid)">
  <B><dtml-var name></B> <dtml-var oid>
 </dtml-tree>
</dtml-let>

However, with only a small amount of data in the tree table this is 
behaving in a very strange way, where clicking on expand/collapse 
links will have random effects, either doing nothing 
expanding/collapsing a random part of the tree or, occasionall, 
doing what it should do.

Is this a problem anyone else has come across?

Cheers,
Stephen
