I tried creating a zclass that had a property sheet with a selection type,
which i had reference a property of a given name. I then went to the
root folder in zope and created that property as a lines type. When
i created an instance of my zclass though, it said "no value for given_name".
To fix this i changed the OFS/properties.dtml file to use the same syntax
as the properties.dtml in z2.1:
<select name="<dtml-var id>">
It used to use hasProperty and getProperty methods. I'm not entirely sure
why they were used, or what they are suppose to do differently, but it
doesn't seem to work.
