Description Max Sauer 2005-09-14 13:43:03 UTC 
When moving two larger components selected at once and exceeding JFrame's
border, following two exceptions may pop up:

java.lang.IllegalArgumentException: An explored context (jScrollPane1
[JScrollPane]) must be within the root context (Form NewJFrame7).
	at org.openide.explorer.ExplorerManager.checkUnderRoot(ExplorerManager.java:488)
	at org.openide.explorer.ExplorerManager.access$300(ExplorerManager.java:52)
	at
org.openide.explorer.ExplorerManager$1SetExploredContextAndSelection.run(ExplorerManager.java:333)
	at org.openide.util.Mutex.readAccess(Mutex.java:261)
...
or

java.lang.IllegalArgumentException: A node selection cannot contain nodes
(jTree3 [JTree]) not underneath the root (Form NewJFrame).
	at org.openide.explorer.ExplorerManager.checkUnderRoot(ExplorerManager.java:488)
	at org.openide.explorer.ExplorerManager.access$300(ExplorerManager.java:52)
	at
org.openide.explorer.ExplorerManager$1AtomicSetSelectedNodes.checkArgumentIsValid(ExplorerManager.java:194)
	at
org.openide.explorer.ExplorerManager$1AtomicSetSelectedNodes.run(ExplorerManager.java:246)
...
(stack traces attached)

Steps to reproduce:
---------------------
1) Create a JFrame Form
2) Add two JTrees, align them together (I have also tried two larger JTextPanes)
3) Select both
4) Move them partially or whole outside of JFrame's border

Comment 2 Milan Kubec 2005-09-14 16:26:21 UTC 
Raising priority, very easily achievable exception and lost layout - those
components are moved to Other Components node (they are not visible in the form).
Comment 3 Jan Stola 2005-09-14 17:22:12 UTC 
The components are moved to Other components because they were dropped there.
The exception is harmless, but I am fixing it preferentially because it
has been identified as high priority issue :-/.
Comment 4 Max Sauer 2005-09-15 09:54:08 UTC 
The exceptions have been fixed well, thanks. (Verified in 200509141800)
But the behaviour of moving one component differ from behaviur of moving two --
I filed issue 64409 against it (P4).
