[jboss-user] [JBoss Seam] - Re: Could not instantiate Seam component error

[hstang]

If you provide a no-args constructor, the exception dealing with instantiation will be gone.  This is the only way Seam can construct your seam components properly.  Yes, as you suggested, use the @Create to initialize other important properties pertaining to the class.  The annotated method is called once Seam has fully initialize the component.

As for @DataModel, this will outject the annotated property to the scope of the owning component.  In your case, the conversation.

And for @DataModelSelection, this will inject the selected model object, if it's successfully look up in the contexts.  You have to ensure that the conversation is long-running, just long enough though, so that @DataModelSelection object can be successfully be retrieved through the @DataModel property.
