[Zope] Difficult question related to creating instances of objects...

[zope-mailinglist]

create a dtml-method in a zclass

lets call it: returnParadigms

the content should be:

<dtml-var expr="objectIds('paradigm')">

now create the property in the zclass
select selection as type and select the function as value

now the user should be able to select id's from the list
