[midPoint] Re. Referring to resource variable inside expression.

[Deepak Natarajan]

Hi Ivan -

Thanks - I tried with $c:input and it worked.

It's a bit weird since in an object template (which I use for
post-creation assignments etc),  doing it like this worked :

<mapping>
    <source>
        <name>varname</name>
        <path>varpath</path>
    </source>
    <expression>
        <script>
            <code>
                    tokenize(varname...)
            </code>
        </script>
    </expression>

seems to work, but this fails when I try something similar in a resource
configuration...thought it is quite possible my varpath had an error in
it...(i used $account/attributes/ri:var)

but using 'input' works, thanks!
