Which does exactly the same as the let tag does in the above statement, ie a lookup in the namespace and then calling it if it is a method. Example: This kind of hoopjumping is exactly why in Zope 2.3 you now can use the method 'getId()', which will hide the confusion for you. From Zope 2.3 onwards, *always* use getId(): or: -- Martijn Pieters | Software Engineer mailto:[EMAIL PROTECTED] | Digital Creations http://www.digicool.com/ | Creators of Zope http://www.zope.org/ - ___ Zope maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope-dev )

Due to Zope's acquisition magic, it is difficult to compare method's to one another: the "same" method compare different, if accessed on different access paths. Thus, you want to work with strings only. The problem is: DTML does not let you test for types.
