I have created a BIRT report with input parameter. But when I run the report in Pentaho, I get the input field label as "NULL".

I checked the BIRT report sample and I notice that the input field label is getting the value from <text-property name="displayName">My Label</text-property>. But I'm not able to find where to create the "displayName" in the BIRT report designer. Can anyone provides a guideline where can I create the label name in BIRT report designer. At the moment I add in the label by modifying the XML source.

Thanks.
