Well, I think that this is just a workaround, but not a bugfix ;) Assume that ulines property is used to define the set of possible values for a multiple selection property. In this case one would expect to get a ustring vaule back. And as Maik already mentioned, it is even possible to use something like [1, 2, 3,4] as the possible values of the multiple selection . OK, this case does not work very well with older version of Zope too, but I think that this shows the general problem: Currently (including older Zope versions), there absolutely no type conversion for multiple selections. My idea of a proper fix is to add a method to the PropertyManager which returns the type of the first element of the list of the allowed values. As a very trivial and not very elegant approach (sorry, I don't much time at present;): def type_as_string(self, selectValues): if type(selectValues) == type(''): return 'string' elif type(selectValues) == type(u''): return 'ustring' elif type(selectValues) == type(0): return 'int' elif .... With this method available, the multiple selection part of OFS/dtml/properties.dtml could be changed from: <select name="<dtml-var id>:utf8:list" multiple size="<dtml-var "_.min(7, _.len(_[select_variable]))">"> to: <select name="<dtml-var id>:utf8:list:<dtml-var "type_as_string(selectValues)">" multiple size="<dtml-var "_.min(7, _.len(_[select_variable]))">"> _______________________________________________ Zope-Dev maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope )
