NPE in parameter conversion after rule redirect: String to Long?
----------------------------------------------------------------
Key: JBSEAM-3836
URL: https://jira.jboss.org/jira/browse/JBSEAM-3836
Project: Seam
Issue Type: Bug
Affects Versions: 2.1.0.SP1
Reporter: Francisco Jose Peredo Noguez
I am getting this WARNING in my logs:
WARN org.jboss.seam.navigation.Param - could not create converter for:
categoriaBienCveCategoria
(The full stacktrace is available in the referenced forum thread)
This happens when I hit a navigation rule like this:
<rule if-outcome="persisted" if="#{not empty
categoriaBienCveCategoriaFor}">
<end-conversation/>
<redirect view-id="#{categoriaBienFrom}">
<param name="categoriaBienCveCategoria"
value="#{categoriaBienCveCategoriaFor}"/>
<param name="categoriaBienFrom"
value="/Crud/CategoriaBien/CategoriaBienList.xhtml"/>
</redirect>
</rule>
As a side effect the categoriaBienCveCategoria is not set with the value in
#{categoriaBienCveCategoriaFor}, and that makes my validation rule useless.
But I found a weird workaround, if I change:
<param name="categoriaBienCveCategoria"
value="#{categoriaBienCveCategoriaFor}"/>
to
<param name="categoriaBienCveCategoria"
value="#{categoriaBienCveCategoriaFor+0}"/>
Everything works fine (and the WARN dissapears) I think this is a bug in the way Seam
2.1.0SP1 is dealing with conversions, I think that maybe seam is failing to converte
categoriaBienCveCategoriaFor from String to Long, to match the setter of
categoriaBienCveCategoria.

Francisco Jose Peredo Noguez commented on JBSEAM-3836:
------------------------------------------------------
I wonder... isn't Seam trying to be too smart for its own sake? Why does it try to
guess the type of an EL expression like "#{categoriaBienCveCategoriaFor}? Why not
just wait until it needs to evaluate it, and the ask for then ask for type of the
resulting value?
