Max,

I've changed the code in the mmRoleRules constructor to the following:

public mmRoleRules(ImmBusinessRuleHost hostObject) : base(hostObject)
{
	mmRole oRole = (mmRole)hostObject;
	if (!mmString.Empty(oRole.DescriptionField))
	{
		this.AddRequiredField(oRole.DescriptionField);
	}
	else
	{
		if (oRole.DescriptionFields != null && oRole.DescriptionFields.Length > 0)
		{
			foreach (string DescField in oRole.DescriptionFields)
			{
				this.AddRequiredField(DescField);
			}
		}
	}
}

Thanks,
