You have to specify the entity class for selectMany.
See <s:convertEnitity /> docs.
Where do you do that?
The docs says for s:convertEntity "Assigns an entity converter to the current component. This is primarily useful for
radio button and dropdown controls."
As well, ConvertEntity doesn't know anything about converting to a list, which is what I need in this case.
You used to have to, but you don't anymore. There is an example using a selectMany in the ui example (n.b. it doesn't matter if its checkboxes or a list - they are the same in JSF). Does a dropdown list work?
I looked at the UI example, and fair-enough it works. However, it works for a List implementation. The conversion error I encountered was when I had a Set implementation (see above).
So the quick fix was to change my implementation to List. Is this really necessary?
Can you add a jira issue, I'll take a look.
