EXTRA RELEVANT SYSTEM CONFIGURATION :
The error appeared after performing update.

A DESCRIPTION OF THE PROBLEM :
An attempt to select any "sub package" dislayed
in the "Objects" frame, throws Exception.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1.Click on "Browsing" Tab
2.Select Any Package from the Left most
"Packages" frame
3.Select (Single or double click) any sub
package from the "Object" frame

EXPECTED VERSUS ACTUAL BEHAVIOR :
The "sub package" displayed in the "Objects"
frome is wrong as its not a Object. So on
selecting of any of these sub packages, whould
expand the package and display the Objects in
the selected package.

Or

sub packages should not be displayed int he
Objects frame.
