Hi Isomorphic,

please take a look at this test case.

            lg.fetchData();

            addItem(lg);

    }
}

Display field of "testField" should be "information".

You configured the displayField to be "test2Field" but you named the field "testField2".

Hi Isomorphic,

sorry, my fault. Now you should be able to see the problem. This could be related to 12.0p Join generation change between March version and current nightly

If the problem is simply that you are seeing the field test2Field not populated because of a change in join generation, then please just watch the other thread.

If there is a separate problem where the field is populated but is not appearing when configured as a displayField, let us know on this thread.

Hi Isomorphic,

this is a separate problem, but that fix could also fix this problem, but maybe not! Because with March version of smartGWT this works fine.

If you want to see this problem:

• Please take a "BuiltInDS.java" from post #1 and "animals.ds.xml" from #3 post.
• Display field of ListGridField "testField" should be "information" and not "diet".

Best regards

Hi Isomorphic,

I can confirm that this fix 12.0p Join generation change between March version and current nightly has been fix this problem as well.
