Hi I have a variable `x' , type is `instance' -record-, was created with something like http://host/page?x.attr1:record=Value1 I want to add a new attribute `attr2', in Zope something similar with:<dtml-call "REQUEST.set('var',Expresion)"> OR (python ) x.attr2=VALUE2 but the assign operator `=' is not allowed in Python expresion, so I can not call <dtml-call "x.attr2=VALUE2"> So I try: <dtml-call "x.__dict__.update({'attr2':'attrValue'})"> (the expresion in Python is (VERY) correct) When I try to save the DTML-METHOD , (NOT at the EXECUTION time), I get the error: ####### ... ... File /usr/lib/zope/lib/python/DocumentTemplate/DT_Util.py, line 357, in name_param (Info: ({'': '"x.__dict__.update({\'attr\':\'attrValue\'})"'}, 'call', 1, 'name')) File /usr/lib/zope/lib/python/DocumentTemplate/VSEval.py, line 175, in __init__ (Object: x.__dict__.update({'attr':'attrValue'})) TypeError: illegal name used in expression ... ##### I have take a look at VSEval.py, and looks like I can not use names that are starting with `_' and are not in ('_', '_vars', '_getattr') How can I add a new attribute to a variable? I can do this with an external method, but maybe exist other way... Thanks!
