Zen DataCombo ListBox ClassQuery not displaying all columns

Hello,

1)

I am trying to have a ZEN datacombo to display list of Namespaces column using a Class Query.

<dataCombo id="NamespaceId" queryClass="%SYS.Namespace" queryName="List" showQuery="true" />
This Classquery works fine in <tablepane> and also from terminal.

But the datacombo is not displaying the "Namespace" column but only the last two columns. I have tried property displaycolumn="1". But this is not working.

Thanks in advance.

Regards,

Jimmy Christian.
