I get a nullpointerexception when i move the select box back to the item that
is noSelectionLabel. When I select a valid entry inside the drop down, it
works OK. But when we go back to resetting it by selecting the
noSelectionLabel, it pops the following error.
Is this a bug?

Just override the hashcode and equals on the id of the entity. and when you
submit the form you will need to catch the entity id. which you will get .
those few errors you got are the exact errors we were banging our head against.

all the best team!
All I would ask is keeping the document (reference manual + api) updated with
new features. since I'm just learning Seam and developing a personal project in
it for now. Forums are very nice help as well.

I would suggest go ahead and open the source code. Look into the resources
folder and you will see a file called numberguess.drl . Examine that and then
look at the source code.
Contents are
package org.jboss.seam.example.numberguess
import org.jboss.seam.drools.Decision
global Decision
oh Mr. Bean i forgot to say the above stuff was the
seam(distribution)/examples/drools/ . I learned the functionality from that
example, which is pretty good. Personally i'm not using drools for now. Dont
want to get tangled into alot of new stuff.

Correct me if i am wrong. Isn't the functionality requested the same as seam
generate-entities ? or maybe i misunderstood it. data model
