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

{
	Object[] keyValue = null;
	OneKeySelection( Object[] keyValue )

		return keyValue;
	}
	public Object[] getMin( )

		return keyValue;
	}
	public boolean isSelected( Object[] obj )
	{
		if ( CompareUtil.compare( keyValue, obj ) == 0 )
			return true;
		else
			return false;
	}
