Hi, I have a ZClass based product with a property sheet which has a multiple selection property called "groups", listing the group or groups a person belongs to. I'd like to be able to access this property as a list, so that I can create expressions like the following: <dtml-if expr="'Some group' in groups"> ... </dtml-if> However, in this expression, groups is treated as a string, so I get an error saying that the left hand side of the 'in' expression must be a character, not a string. I can work around the problem by iterating over groups with dtml-in and creating a new list, something like this: <dtml-let grouplist="[]"> <dtml-in groups> <dtml-call "grouplist.append(_['sequence-item'])"> </dtml-in> <dtml-if "'Some group' in grouplist"> ... </dtml-if> </dtml-let> Can anyone see a better way of doing this? If dtml-in can see the property as a list, why can't the 'in' operator? Cheers, Alex.
