[udig-devel] [jira] Created: (UDIG-1763) Navigation "Back" & "Forward" d

["Frank Gasdorf (JIRA)" <jira@xxxxxxxxxxxx>]

Navigation "Back" & "Forward" do not work with Zoom In and Scroll Commands
--------------------------------------------------------------------------

                 Key: UDIG-1763
                 URL: http://jira.codehaus.org/browse/UDIG-1763
             Project: uDIG
          Issue Type: Bug
          Components: application, tools and editing
    Affects Versions: UDIG 1.2.1, UDIG 1.2.0, UDIG 1.2.RC3, UDIG 1.2.RC2
            Reporter: Frank Gasdorf
            Priority: Critical


Szenario:
1.a Scroll with Mouse-Wheel 
1.b One click on "Zoom In" Command in Toolbar 

-> "Back" Action in Toolbar got enabled

2. Click on "Back" Navigation Action a ClassCastException is thrown with the following Stracktrace:

{noformat} 
java.lang.ClassCastException: net.refractions.udig.tools.internal.InvalidateCommand cannot be cast to net.refractions.udig.project.command.UndoableCommand
	at net.refractions.udig.project.internal.command.navigation.NavComposite.rollback(NavComposite.java:113)
	at net.refractions.udig.project.command.CommandManager$Executor.undo(CommandManager.java:537)
	at net.refractions.udig.project.command.CommandManager$Executor.run(CommandManager.java:328)
	at net.refractions.udig.project.command.CommandManager$Executor.run(CommandManager.java:311)
	at org.eclipse.core.internal.jobs.Worker.run(Worker.java:55)
{noformat} 

Within the UpdateThread class is a explicit cast from InvalidateCommand (and holds a TransformDrawCommand) to UndoableCommand.

Also checked with the 1.1.1 Release ->  same behavior
