@Out and @Datamodel combination error

supernovasoftware.com Apr 11, 2007 11:33 PM

I had the following in a SFSB that worked until I upgraded to Seam 1.2.1.

 @Out(scope = ScopeType.CONVERSATION, required = false)
 @DataModel(value="dosRecordPend", scope=ScopeType.UNSPECIFIED)
 private List<Map> dosRecordPend;

This was obviously an error on my part, but caused an runtime exception.

java.lang.ClassCastException: java.util.ArrayList cannot be cast to javax.faces.model.DataModel

Is there any reason to use @Out and @Datamodel in combination? If not, should this not throw and deployment error such as when you do not use

scope=ScopeType.UNSPECIFIED or scope=ScopeType.Page

with @Datamodel?

It doesn't make sense to use @Out and @DataModel together (you are outjecting two objects to the same variable). Perhaps Seam should have a warning if you try to do this?
