How to validate an integer array

[Chetan Pandey]

Hi All:

 

In my form I have 

 

Int [] roleIds = null.

 

This is used as the Underlying Datatype of a multiple-select Drop-down.

 

Everything works fine but I am not sure how to validate?

 

The following that I tried did not work:

 

<field property="roleIds" depends="validwhen">

             <arg0 key="lms.role"/>

              <var>

      <var-name>test</var-name>

      <var-value> (*this* != 0)</var-value>

    </var>

   </field>
