OGNL expression problem

Hello,

I am encountering problems using OGNL expressions of the following form:

<binding name="some" expression="selectedValue == previousValue"/>

the first time this binding is invoked it executes OK, but the second time
it throws an exception, stating something about an invalid OGNL expression,
pointing at some "Eq" token. It seems "Eq" is an OGNL-internal
representation of the parsed "==" token.

I also tried the form

<binding name="some" expression="[selectedValue == previousValue]"/>

but that didnt help either.

Hints?

BTW, is there a way to avoid having to deploy ejb.jar with every tapestry
application? I just cant see why I have to do that with an application that
has nothing to do with EJBs - into a plain servlet engine. This is just
wrong IMO.
