[jboss-user] [JBoss Seam] - Re: Method expressions being mistaken for value
Ahh, I found the problem. Look at the following code from SeamExpressionEvaluator:
@Override
| public Object evaluate(VariableResolver resolver) throws ELException
| {
| try {
| try {
| if (me==null && ve==null) {
| initMethodExpression();
| }
| if (me!=null && ve==null) {
| return me.invoke(createELContext(resolver, mapper),
new Object[0]);
| }
| } catch (javax.el.ELException e) {
| if (ve==null) {
| initValueExpression();
| }
| if (ve!=null) {
| return ve.getValue(createELContext(resolver,
mapper));
| }
| }
| throw new ELException();
| } catch (javax.el.ELException e) {
| throw new ELException(e);
| }
| }
My problem was that Bean.method was throwing an exception, which was being wrapped by an
ELException by JBoss EL and then filtering up out of me.invoke, causing Seam to then try
to evaluate it as a value expression (instead of propagating out the exception, like it
should be doing). Not sure the best solution here...
