linzhixing commented on CMIS-573:
---------------------------------
In the above code, as a code test, CmisExtensionElement is only retrieved from
the repository and backed.
If possible, I would have customize it to retrieve user-defined parameters from
a client side JSP, rewrite or create a new CmisExtensionElement and set it back
to the document.
So, I still need the bi-direction, that is to say, getting and setting
CmisExtensionElement of the same document.

>would be able to send them back and forth.
You are saying it is impossible?
I would want to do the things like Alfresco does in its aspect update via CMIS.
My main purpose of all of this is updating custom properties which cannnot be
provided CMIS method like name, ACL, etc. CmisExtensionElement is considered to
be a hook. Could you tell me a suitable way?
Regarding using 0.6.0. is not an inevitable restriction, just because the
repository has been developed by 0.6.0.
If upgrading the version makes CmisExtensionElement issue better, it would take
priority.
