Possible Bug Found While Invoking groupBy Method on ListGrid

[lextra]

Hello,

I think we found a bug while invoking the groupBy method on a ListGrid:

final DataSource dataSource = DataSource.get(DATA_SOURCE);
final ListGrid listGrid = new ListGrid();
listGrid.setWidth100();
listGrid.setHeight100();
listGrid.setDataSource(dataSource);
listGrid.setAutoFetchData(Boolean.FALSE);
listGrid.groupBy("I_ID");
layout.addMember(listGrid);

If you add that in a onModuleLoad, the following Javascript error appears through window.alert (and nothing else, I mean no panel at all):

com.google.gwt.core.client.JavaScriptException: (TypeError) @com.google.gwt.core.client.impl.Impl::apply(Ljava/lang/Object;Ljava/lang/Object;Ljava/lang/Object;)([JavaScript object(46), JavaScript object(146), JavaScript object(149)]): this.fields is undefined

Do you have an idea where does this come from? We're using the p20141130 of SmartGWT 4.1 Power.

Cheers,

We're not seeing this effect with sample DataSources, so we suspect the DataSource you are providing is flawed in some way.

Actually, our dataSource.ds.xml is quite simple (it uses the default connection):

<?xml version="1.0"?>
<DataSource ID="dataSource" dataFormat="iscServer" serverType="sql" tableName="T_FEES_MIL_EXECU"> 
	<fields>
		<field name="T_DT" type="date" canEdit="false" />
		<field name="I_ID" type="integer" canEdit="false" />
		<field name="R_ID" type="integer" canEdit="false" />
		<field name="INTERNAL_ORDER_ID" type="text" canEdit="false" />
		<field name="ISIN" type="text" canEdit="false" />
	</fields>
</DataSource>

And if we remove the groupBy method, it works well.

The same datasource and groupby functionality works in SmartClient Version: v8.3p_2014-07-12/PowerEdition Deployment (built 2014-07-12)

This has been fixed for builds dated December 4 and later - alternatively, calling setGroupByField() instead of groupBy() should work in your case (which is before draw).

Thanks! We're going to try this tomorrow and we'll make you feedback.

It seems to work well. Thanks a lot for your reactivity!
