Updating JSF components via Seam remoting...

[bkyrlach]

I have a stateful session bean with a method annotated with @WebRemote that returns a string which is being used to dynamically update a h:selectOneListbox. However, because the options didn't exist when the page was initially rendered (passed through the facelets view resolver), when I attempt to submit the form, the page fails validation.

Is there a way to update the servers knowledge of the rendered view to contain the newly created options?

No, because the component tree is kept in a serialized form in the page.

Well, in that case, would it be possible for me to pass the serialized form to my @WebRemote method, deserialize it, update the object graph, and reserialize it, and update the page with the new version of the serialized form?

Also, if I changed

<context-param>
<param-name>javax.faces.STATE_SAVING_METHOD</param-name>
<param-value>client</param-value>
</context-param>

to save state on the server, would that give me a way to do what I want? It seems as if this should be possible somehow. One of the greatest uses for AJAX is to update form fields with dynamicall retreived information. I really like the way that Seam integrates with AJAX so nicely, it'd be great if I could get this to work.

Thanks for all your help.

I don't think either of these things would work, no.
