How do I construct a method of an object, so that whenever that method is called, the current namespace is passed with it? I.e.: class myclass: [...] def myfunc(self, context): if context['sequence-index'] == 10: raise 'sequence-index is %s' % \ context['sequence-index'] called from DTML, like so: <dtml-in "objectValues('Spam')"> <dtml-var myfunc> </dtml-in> will raise an exception if sequence-index is 10 or more? Specifically, the reason I want this function is that I feel using <dtml-if sequence-even> <tr bgcolor="<dtml-var color_sequence_even>"> <dtml-else> <tr bgcolor="<dtml-var color_sequence_odd>"> </dtml-if> is a bit tedious (and ugly!) in the long run.. If this isn't implemented, where would the right place to implement it be? -Morten
