There seems to be an error where only the first of the filtered grupes is used.

In FilteredMemberPickerDataType.cs the filter seems to be applied, but it only use the first value.

 
 
//- Add the filters
 
 
if (filters.Length == 1)
{
sb.Append(
 
"(cmsMember2MemberGroup.MemberGroup = " + filters[0] + ")");
}
 
 
else if (filters.Length > 1)
{
 
 
foreach (string s in filters)
{
sb.Append(
 
"(cmsMember2MemberGroup.MemberGroup = " + filters[0] + ") OR ");
}
 
 
//- Remove the trailing OR
sb.Remove(sb.Length - 3, 3);
}

suggest filters[0] in the foreach loop is changed to s. or something like this

//- Add the filters
 
 
if (filters.Length > 0)
{
 
 
foreach (string s in filters)
sb.Append(
 
"(cmsMember2MemberGroup.MemberGroup = " + s + ") OR ");
 
 
//- Remove the trailing OR
sb.Remove(sb.Length - 3, 3);
}

Cheers,
