Problem with validWhen while using map backed beans.

           Summary: Problem with validWhen while using map backed beans.
           Product: Struts
           Version: Nightly Build
          Platform: Other
        OS/Version: Other
            Status: NEW
          Severity: Normal
          Priority: Other
         Component: Validator Framework

Version of struts: nightly build as of 25-may-2004

I am getting a stack trace when using property names which populate map 
backed beans along with the "validwhen" validation rule.

Here is the JSP snippet:
<html-el:text property="value(partyCd)"
              size="10" 
              maxlength="10"/>
<html-el:text property="value(requirementRoleCd)"
              size="10" 
              maxlength="10"/>

Here is the code which current WORKS with the deprecated "requiredif" validation 
rule:
<field property="value(partyCd)" depends="requiredif">
  <arg key="partyCd.label" position="0"/>
  <var>
    <var-name>field[0]</var-name>
    <var-value>value(requirementRoleCd)</var-value>
  </var>
  <var>
    <var-name>fieldTest[0]</var-name>
    <var-value>NOTNULL</var-value>
  </var>
</field>

Here is the code which fails when using "validwhen" :
<field property="value(partyCd)" depends="validwhen">
    <arg key="partyCd.label" position="0" />
    <var>
        <var-name>test</var-name>
        <var-value>((value(requirementRoleCd) == null) or (*this* != 
null))</var-value>
    </var>
</field>

The stacktrace (partial) :
