Bernd Eckenfels resolved VFS-558.
---------------------------------
Resolution: Fixed
Fix Version/s: 2.1
Assignee: Bernd Eckenfels
I just added a test case, but it does only produce the problem when ON_CALL is
used. Because otherwise the getType() on the source will not re-check the
renamed file and uses the correct type.
BTW: a lot of the test cases fail with ON_CALL (mostly because they use
assertSame() to verify exepcted results. We will have to change that and then
think about running the provider tests with all strategies. Maybe even with a
NullFilesCache.)
Anyway, I fixed the rename in trunk, can you try? (and really consider not
using ON_CALL :)

> I am getting the following exception in my code:
> java.lang.UnsupportedOperationException

> org.apache.commons.vfs2.cache.OnCallRefreshFileObject.moveTo(OnCallRefreshFileObject.java:184)
> ...
> I guess it is caused by the fact that children field is set to
> EMPTY_FTP_FILE_MAP at the moment onChildrenChanged() is invoked.
> I also do not like line 1866 in AbstractFileObject.java. To me it looks like
> it might be the real cause of the problem:
> FileObjectUtils.getAbstractFileObject(destFile).handleCreate(getType());
> Must it not be destFile.getType()?
> But even if I am right about AbstractFileObject.java:1866,
> FtpFileObject.onChildrenChanged() must be corrected as well.
