5:40 a.m.
1. I'm using the Seam2 beta with JBoss 4.2 and I am having a problem with the
following expression.
Expression
| <h:commandButton id="select" value="Select"
action="#{organizationEditor.select}"
| class="primary"
| rendered="#{not empty partyFinderClient and
partyFinderClient.supportsSelect}"/>
|
When the expression is evaluated it throws an IllegalAccessException (see bottom). The
class is anonymous, the method is public and also overrides an abstract method. Is there
a reason that i cannot access methods on an anonymous class using EL?
2. Where can I get the source for jboss-el.jar? This lib is distributed with the source
for JBoss 4.2 and Seam 2. I can't seem to find it among the JBoss projects.
Thanks
Richard
