Detail grid Expand button got messed up when set columnTemplate :comment render

[Soumya]

Master Grid with Detail grid and columnTemplate on Master Grid destroys Expand button .

When i inspect the arrow element this is what i see <td class="pq-grid-cell pq-cell-select ui-state-highlight" pq-col-indx="0" tabindex="0">[object Object]</td>

I am suppose to see <div class="ui-icon ui-icon-triangle-1-e"></div> in the place of [object Object].

This started happening once i set the columnTemplate: { render: commentRender }, in Master Grid Object.

Please see the attached screen shot for more in detail.

What is the source code in your commentRender.

Either you don't override the default render of detail column.

or

return null when dataIndx == 'pq_detail' inside render callback.

That worked thank you very much. Was so simple may be i should have figured out myself .
