Hi Andreas,
I tryed in ArgoUML V0.24, and the current subversion version, but I can not
reproduce this problem.
Can you tell me exactly what you did step by step, or attach a small project
that shows the issue?
Regards,
Michiel

Subject: [argouml-dev] Exception adding "in State" / Activity Diagram
Hi,
if you add a State in the "in State" list of the ObjectFlowState,
an Exception is thrown:
Exception in thread "AWT-EventQueue-0" java.lang.ClassCastException:
org.omg.uml.behavioralelements.statemachines.SimpleState$Impl cannot be
cast to java.lang.Comparable
at java.util.Arrays.mergeSort(Arrays.java:1144)
at java.util.Arrays.sort(Arrays.java:1079)
at java.util.Collections.sort(Collections.java:117)
at org.argouml.util.SortedListModel.addAll(SortedListModel.java:153)
at
org.argouml.uml.ui.UMLAddDialog.constructListModel(UMLAddDialog.java:298)
[...]
The problem is that SortedListModel uses Collection.sort to sort the
elements of a collection. The collection contains elements of type
SimpleState$Impl, which in turn does not implement "Comparable".
How could this be fixed?
org.omg.uml.behavioralelements.statemachines.SimpleState is a generated
class, so how could this class implement another interface (Comparable)?
My workaround is to comment "Collection.sort" in SortedListModel, but this
is no solution.
Andreas
