-----Original Message----- From: vanroose wim [mailto:vanroose@ruca.ua.ac.be] I    have   an   ExternalMethod  Article that  may only be called once. But I want to use the returnvalue, a string,   in two places.   Use of namespace doesnot solve the problem  <!--#with  "_.namespace(story_id=Article)"--> <!--#var story_id--> <!--#var story_id--> <!--#/with--> The function is still called Twice   Instead, use the namespace to assign the result of the function to 'story_id', <!--#with "_.namespace(story_id=Article())"-->  <!--#var story_id--> <!--#var story_id--> <!--#/with--> This way, you only call the function once (in the namespace call) and assign its result to story_id.  Thus, when you #var story_id it's just displaying a string and not calling a method.
