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

[Ivan Noris]

Hi Deepak,

just a blind shot - try to use implicit variable named "input" (it is
mapped to the "source" of the inbound expression, in your case, ri:orgdesc).

See an example (adapted from my customer's resource) written in Groovy
(not XPath):

<attribute>
    <ref>ri:orgUnitHierarchy</ref>
    <displayName>Organizational Hierarchy</displayName>
    <access>read</access>
    <inbound>
    <expression>
        <script>
            <code>
String[] tmpHierarchyList = *input* ? *input*?.split('\\.') : []
tmpHierarchyListNew = []

<!-- some processing skipped here . . . -->

return tmpHierarchyListNew.join(':')
</code>
        </script>
    </expression>
      <target>
    <path>$user/extension/mycustomer:ouPath</path>
      </target>
    </inbound>
</attribute>

I do not use XPath in expressions unless absolutely necessary because
the debugging is quite _challenging_ ;) and it's lot easier to debug
Groovy statements.

Regards,
Ivan
