NPE in Visitor Validation migrating from 2.0.14 to 2.1.6

If I attempt to use an empty message node in my visitor validator
configuration, I get a NullPointerException from
TextParseUtil.translateVariables (line 155) because "expression" (the
default message if message key is null) is null.

 

I can sort of work around the issue by adding a default message, but
then that string is prepending (according to guide and as witnessed) to
the validation error string.  I do not want this string appended.

 

Does anyone have any suggestions?

 

<field name="userBean">

            <field-validator type="visitor">

                        <message key=" "></message>

            </field-validator>

</field>

 

BTW, other forms such as "<message key=""></message>", "<message/>", and
"<message></message>" all produce the same problem.

 

Thanks,

Derrick

This was fixed in xwork trunk(yesterday). I can't find the ticket now :)
