User list reading problem.

Hello Mikko,
after solving case "AssociationLN access rights mismatch." in GXDLMSDirector 9.0.2302.108 (thank You very much!), reading of user list results in window with conversion error.
In my oppinion the sent data are OK.
To avoid block transfer I resized user list to one item {100, {'u','s','r','\0'}}.

This is the log from Director:

The System.InvalidCastException in english is "Object type System.String cannot be converted to type System.Byte[]".

Thank You.
