Kevin,

In the HookPostGetData() of mmRole you allow for an override by the user to an array of discription columns when you compose the dataview sort:

if (!mmString.Empty(this.DescriptionField))
{
dv.Sort = this.DescriptionField;
}
else if (this.DescriptionFields != null && this.DescriptionFields.Length > 0)
...

In the constructor of mmRoleRules you don't do this but simply assume that the user will stick with the single string value:

mmRole oRole = (mmRole)hostObject;
this.AddRequiredField(oRole.DescriptionField);

This might be fairly trivial for the experienced but wouldn't it be better to maintain consistent usage between these two related objects?

Thanks,
Max...
