Bug 182296 Crosstab - non-numeric measures
Feature request. Looking at the 2.2.M6 release, it seems that measures (the fields that can be in the matrix part of the output) need to be numeric. I looked at the spec documents and it seems there is no requirement for non-numeric measures

					query.addResultSetExpression( measure.getName( ),

				}
				ColumnMeta meta = new ColumnMeta( measure.getName( ) );
				
				
				meta.setDataType( DataType.DOUBLE_TYPE );
				resultMetaList.add( meta );
