[Zope] tree tag woes continue :S

2000-08-19 Thread Chris Withers 

Okay, my aim here is to effectively have batching with trees.

Why? well because a tree with over a thousand items at the root is
pretty hefty to download to a browser, not to mentioned pretty
antisocial to navigate and use.

My idea, as you may have seen from recent posts, was to do a dtml-in
over the first set of children so I could do the batching there, and
then do a dtml-tree for each one of them to get the tree as before.

Is this a good or a bad idea?
Is having lots of dtml-tree's on the same page acceptable or not?

okay, assuming it it a good idea, the tree to be replaced is:

  dtml-tree branches="postingValues"   
...show stuff here...
  /dtml-tree   

I'm currently trying:

  dtml-in postingValues
dtml-with "_.getitem('sequence-item',0)"
dtml-tree branches="postingValues"   
  ...do stuff here...
/dtml-tree   
/dtml-with
  /dtml-in

but this appears to just render the original tree once for each child.

Any ideas how I should be doing this?

cheers,

Chris

My latest attempt is:

  dtml-in postingValues
dtml-var id-dtml-var titleBR
dtml-tree sequence-item branches="postingValues"   
dtml-var id-dtml-var titleBR
/dtml-tree   
  /dtml-in

which gives me the following weird error:

Error Type: AttributeError
Error Value: 'tuple' object has no attribute 'append'

any ideas?
