[Zope] using a dictionary returned from an external method
I have some DTML that needs to call an external method that returns a dictionary. I don't have any problem referencing the resulting dictionary by doing something like dtml-var externalMethod()['key1'] dtml-var externalMethod()['key2'] . . . However, I need to do this for several keys, and I don't want to call externalMethod several times. Is there a way to assign the method result to another variable, or is it possible that DTML is smart enough not to do the call multiple times? Or is there some other approach that I am not even thinking of? Any suggestions will be greatly appreciated.
