WebForms error with maxOccurs > 1

[mark_smithson]

According to the docs in the wiki, when a schema element has maxOccurs > 1, the web form will render a repeater for the element.

This works fine for a simple type such as xs:normalizedString, but does not work when the element type is restricted by an enumeration. When you try and render the form, you get this error.

Is this a bug, or is it intentional and I am missing something?

[arielb]

can you provide the schema you used to produce this issue?  it looks like a bug.

To follow-up on Ariel's post, what would be preferable is if you could (a)  open a support case, so that we can immediately look into and potentially offer up a patch or (b) open a bug at http://issues.alfresco.com and attach your XSD.

Thanks!
