Hi there, I've posted about this before but didn't get a satisfactory answer yet. I'm using an external method with a DTML Document, and inside that external method I want to look at the properties of the DTML Document. I keep having problems with it so I reduced the problem to the following. I have this external method: def getPropertyIds(self): return self.propertyIds() Inside a DTML Document I have this: <!--#var standard_html_header--> <p><!--#var "getPropertyIds()"--></p> <p><!--#var "propertyIds()"--></p> <!--#var standard_html_footer--> I would expect these two to give the same list of property ids, but instead the external method returns the list of properties in the *folder*, not in the document (like <!--#var "propertyIds()"--> does). Am I doing something wrong, or is this a bug? A related question: is there a way to check if a property id (acquired from the folder *or* defined locally in the DTML Document) exists or not (and get at its contents), from within an external method? hasProperty is not working well either... Regards, Martijn
