My guess is that you have a sort attribute on your dtml-in, which would touch everything in the sequence up front. > Second hard ?.....

I've tried about 5 different approaches to no avail :( I'm not sure how (or why) you would wrap a class around an instance. In order to override methods on an instance by instance basis, you would most probably need to create a object proxy wrapper that override __getattr__ so that it can fire off the right methods. If these methods are accessed TTW, then you could just use __bobo_traverse__ for this too. Maybe restate the problem in a different way. /---------------------------------------------------\ Casey Duncan, Sr. Web Developer National Legal Aid and Defender Association [EMAIL PROTECTED] \---------------------------------------------------/ _______________________________________________ Zope-Dev maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope )
