Version:           2.2.4 (using KDE 4.2.4)
OS:                Linux
Installed from:    Fedora RPMs

I am starting up an old project after almost 2 years of inactivity.  We used Umbrello on this project.

The old Umbrello was able to read in an .xmi file and define class attributes, lets call them -> Min Green Interval, Max Green Interval, and Yellow Interval to types declared in a stand alone Ada95 class (System_Types).  For example, one system type, System_Types.Seconds is defined as "subtype Seconds is float range 0.0 .. 120.0".  On the class model diagram, the class attribute looks like "+Min_Green_Interval : System_Types.Seconds".  

This was good.  

When reading the same .xmi file, the Umbrello UML Modeller Version 2.2.4 Using KDE 4.2.4 gives the message “an object with the name new_class already exists in the package Logical View.  Please enter a new name”.    The command history window shows “rename objects” occurring.  The attributes Min_Green_Interval, Max_Green_Interval, and Yellow_Interval now are of new_class_13, new_class_14, and new_class_15 types.  

Overall, 28 new classes are created (new_class_1 .. new_class_28).  On the class diagram I am using there happens to be 14 attributes defined of System_Type.something.  

That is wrong.

It appears that System_Types.Seconds (or any other type defined in system_types) is ignored.  The only exception I can find is when System Types is used in a method.  The interface class, clock, has a method called Current_Time.  This procedure returns Time_Of_Day of type System_Types.Time.  It is correct on the new diagram.
