[JBoss Seam] - ClassCastException with generated entities
by anewton
I used seamgen to generate entities from my legacy schema. My EAR was deploying fine before I added these generated classes, now I get a ClassCastException (stack trace and log messages are below). I assume this is caused by some data type not being mapped by hibernate correctly. But I can't figure out where to start looking. Any help would be appreciated.
This is Seam 2.0.0.GA running on JBoss AS 4.2.2.

[JBoss Seam] - Disabling @PerNestedConversation
by wschwendt
I'd be very interested in being able to disable a @PerNestedConversation setting.
In particular, I'd be interested in disabling @PerNestedConversation for component "org.jboss.seam.pageflow.pageflow" (motivation is to use nested conversations for subflows).
Unfortunately, Seam's annotation type @PerNestedConversation is defined with the annotation type @java.lang.annotation.Inherited.
Therefore, it isn't possible to define a subclass of "org.jboss.seam.pageflow.pageflow" in order to override org.jboss.seam.pageflow.pageflow", but WITHOUT the @PerNestedConversation behavior.
Because @PerNestedConversation is defined with @Inherited, every subclass of a Seam component annotated with @PerNestedConversation inherits the @PerNestedConversation behavior, no matter whether the subclass itself is annotated with @PerNestedConversation or not.
Therefore it would be nice if an attribute could be added to @PerNestedConversation to disable the @PerNestedConversation behavior, such as in the following example:
| @Name"org.jboss.seam.pageflow.pageflow"
| @PerNestedConversation(disable=true) // disables @PerNestedConversation setting inherited from superclass org.jboss.seam.pageflow.Pageflow
| @Install(dependencies="org.jboss.seam.bpm.jbpm", precedence=FRAMEWORK, classDependencies="javax.faces.context.FacesContext")
|
| public class OverridingPageflowComponent extends org.jboss.seam.pageflow.Pageflow
| {...
| }
|
Any chances such a mechanismn to disable @PerNestedConversation could be added to Seam?
