conversion support for selectManyCheckbox?

[hstang]

Just wondering if there's any support for conversion for selectManyCheckbox. Currently my code looks something like this

 <h:selectManyCheckbox value="#{someHome.instance.ofTypeSet}">
 <s:selectItems value="#{someList.resultList}"
 var="result"
 label="#{result.labelName}"
 noSelectionLabel="Please select"
 hideNoSelectionLabel="true"/>
 </h:selectManyCheckbox>

ofTypeSet looks something like

private Set<Some_Entity> s = new HashSet<Some_Entity>();

By there seems to be some conversion errors even if I added s:convertEntity to it.

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?

OK...

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.
