[Zope] A TinyTable problem

13 Jun 2001

      I'm having some trouble with a TinyTablePlus logging routine.  I have 
a nearly identical setup on another Zope instance but for some reason 
I can't get this one to work.

The TinyTable is in a subtable called 'log' along with a DTML method 
called 'usercnt'

I put the following in the standard_html_header:

   <dtml-let usercnt="_.getattr(log,'usercnt')">
   	<dtml-call usercnt>
   </dtml-let>

The usercnt method does a few different things but I've narrowed the 
problem down to these couple of lines:

   <dtml-unless logtable2>
	<dtml-call expr="REQUEST.set('logtable2','users')">
   </dtml-unless>
   <dtml-with log>
   	<dtml-call 
expr="_.getitem(logtable2).setRow(name=username_forlog,count='1')">
   </dtml-with>

The TinyTable is successfully updated but I always get an error page 
with the following traceback:

So, any ideas what's wrong?
