El Exception in Seam V2 cr2:

@Name("searchQueryView")
class SearchQueryView{
 private LabelSystems labelSystems;

 public LabelSystems getLabelSystems(){
 return labelSystems;
 }

 public void test(){
 ......
 }
}

when I first entry page 'selectQueryView.xhtml' ,no Exceptin occur,
then, if the link :

<h:commandLink value="test" action="#{searchQueryView.test}"><f aram value="#{sv.autoId}" name="deleteAutoId"/></h:commandLink>

was click, following exception occur

javax.el.PropertyNotFoundException: /main/resourceQueryView/selectQueryView.xhtml @42,32 value="#{searchQueryView.labelSystems.name}": Target Unreachable, 'labelSystems' returned null on 'org.javassist.tmp.java.lang.Object_$$_javassist_6'

my env is:
jboss 4.2.1 + seam V2 cr2

So getLabelSystems() returns null - make it so it doesn't.

So getLabelSystems() returns null - make it so it doesn't.

According to el rule, returnType of 'searchQueryView.labelSystems.name' should be parsed at class level ;the value of el should be eval at instance level, and if the return value of 'searchQueryView.labelSystems' is null, the parser should be stopped and return default value.

spec section?

spec section?

But it work well in seam V1.2.1

You said, according to EL rules.... - so I need to know which section of the EL spec refers to that rule as its not one I'm familiar with. Seam 1.2.1 doesn't implement or specify the behaviour of EL
