Error Theming Layer using data source with feature joins

[CivilEng]

The error is raised when individual distribution is requested.

MgFeatureAggregateOptions aggregateOptions = new MgFeatureAggregateOptions();
aggregateOptions.AddFeatureProperty(UFunctions.GetParameter(this.args, "PROPERTYNAME"));
aggregateOptions.SelectDistinct(true);

// this line raises the exception
dataReader = featureService.SelectAggregate(resId, layer.GetFeatureClassName(), aggregateOptions);

Error: Index is out of range.

I am attaching mgp file and access database in order to replicate the error. the mgp contains the flexible(fusion) and basic layout. Both layouts invoke to thememain.aspx (It's the same that comes with the dotnetviewersample).

I have tested for manage and unmanage data source, just as SHP, SDF, and SQL2008 providers.
