Thanks so much for the response. Unfortunately, it didn't add the 'selected' attribute to the select option.
I tried the following as well, since you had a good point about value types and making sure they were strings... return [(c <http://c.id/>.name, c.name) for c in all_categories] And then, categories = colander.SchemaNode( colander.Set(), widget=deform.widget.SelectWidget( values=categories, multiple=True, default='Category 3', ), validator=colander.Length(min=1), ) I then made sure to update the appstruct similarly with str() so that I end up with this in it: 'categories': [{'id': '5', 'name': 'Industrial Products'}] This didn't add the 'selected' attribute for the select option either. Strange, right?
