Zope                : 2.4.4 beta
CMFoption        : 1.1        

hi,

i create some CMFextFile ( id= test.doc , title = test.doc , content = winword document) from CMFOptions product, but when i want to edit it by webdav protocol, my file is in read only.
I tried some solution given on the web but with no success.
I notice that in the webdav management console, my object doesn't appear as locked whereas a file object open by webdav protocol appears  as locked.
Other thing , in my zope log :
        For a CMFExtfile , LOCK header is present but......
        For a File LOCK header is present and it's good.

Somebody can give me a solution.

thanks a lot.
