Yes. You can't use a set with a selectXXX according to the JSF spec (only
array or list).

Hi,
Thanks, I have seen the JIRA Bug. But why does the UI example works with the
tag s:convertEntity/???

It uses facelets not jsp (use facelets unless you can't for some reason)

I'm sure Christian can explain this better than me but my (poor) understanding
is that:
* If you get a persistent object twice from the same EntityManager, then it
takes care of returning the same object. Thus, the default equals and hashcode
work.
* Equals and hashcode are *hard* to get
I've tried the entity-query to be running sucessful.
So it seem that it is caused by the type. The converter seems to have the
problem of judge the type of the object. What should I do to make it run?

I don't want to use the entity-query because of the limitation of it.

Oh, I see. The @DataModel outjected the List as DataModel, so the
entityConverter can't judge the type. Should I add an issue for s:convertEntity
DataModel not supported?

Reply to the post :
s:convertEntity doesn't need to know about DataModels, and s:selectItems, which
does need to, does know about them.
What version of Seam? Add a message component to the h:selectOneMenu and see
why it's not submitting.

I thought I'm misunderstanding it. It isn't caused by datamodel. I use the @Out
error again. I'm confused.

Thanks. I make it into long-running conversation and it runs.

Why is the conversation approach recommended.
I thought entites do require overwriting equals() anyway because it is used in
many other locations as well.

Exactly that was my point.
I was refering to the wiki page:

that spans the both the select list creation and the submission of the form.

I would strongly recommend to implement a proper
I have been very surprised when I replace Set with List.Now all works
correctly.
It is any glitch
