Subject [jira] [Commented] (CMIS-530) update cmis:name property of a previously uploaded file "appears" to fail with CmisObjectNotFoundException" but actually does the rename
Date Wed, 09 May 2012 20:53:50 GMT


Florian Müller commented on CMIS-530:

A file system is not really a content management system and the FileShare repository has to
do some quirks to implement CMIS.

The only unique id of a document on a file system is its paths. If you rename or move a document,
you also change its id.
The {{updateProperties()}} method that you are using, tries to reload the object after the
update. Since the id of the document changed, it cannot find it anymore and throws an exception.

That's not what you would expect from a real content management system, but it still CMIS

If you want to avoid this exception, use the other {{updateProperties()}} method that has
a {{refresh}} parameter.

ASSUMING, this might be the root cause.  I don't know enough about Chemistry, but what is
more odd:
> 1) the file on the file system DOES get renamed correctly
> 2) the execution path getting there however involves this 
> {code} 
> org.apache.chemistry.opencmis.commons.exceptions.CmisObjectNotFoundException: Object
not found!
> {code}
