Mike,

Just noticed an error in your syntax:

<ww:bean name="'webwork.action.ActionContext'" id="actionContext">
    <ww:if test="principal != null">
        Principal <ww:property value="principal"/> is logged in
    </ww:if>
</ww:bean>

That if should be:


<ww:if test="principal">
   Principal <ww:property value="principal" /> is logged in
</ww:if>

The WW EL is *really* confusing when it comes to null tests IMO. test="principal" means "principal != null" and test="!principal" means "principal == null".

Your example probably works because "null" is meaningless in the WW EL so "principal != null" probably evaluates to true just like "principal".

I haven't been following the list too closely for WW2 - is this something that could be cleared up for the next version? To me, I'd make a lot more sense if test="foo" was a boolean test and "null" had meaning.

Cheers,
--Bill
