Description Alexander Simon 2011-06-23 06:44:32 UTC 
File object has method "getMIMEType()". This method called at mime resolving time. But file system does not delegate mime resolving to file object in two cases.

First: MIMESupport.CachedFileObject does not call "getMIMEType()" for delegated file object.

Second: DefaultDataObject.fixCookieSet() use first 2048 bytes of file object for implicit "text" mime resolving. This implicit mime resolving should be moved at mime resolving time or called just before editing file object.

This is requirements of remote file system.
Comment 1 Jaroslav Tulach 2011-06-23 09:24:11 UTC 
I've reported the FileUtil.getMIMEType problem as bug 199642 (at the same moment you reported this one). Let's track the problem there and let use this bug for the fixCookieSet problem.
Comment 2 Jaroslav Tulach 2011-06-27 09:34:03 UTC 
As far as I can tell, the fixCookieSet is called only when you select the DefaultDataObject - e.g. it is not called while the DDO is being displayed.

Does this still remain a problem? If so, please reopen.

.. and WONTFIX ?
Comment 6 Alexander Simon 2012-05-14 07:03:34 UTC 
Second problem still exists.
Method DefaultDataObject.fixCookieSet() is called when node is shown in favorites tree.
