Florian Müller commented on CMIS-872:
-------------------------------------

That is a limitation of the AtomPub binding. It's not possible to get the 
change log token from the change log feed. See spec section 3.10.2.

OpenCMIS has a proprietary way of transporting the chnage log token. It 
recoginizes a changeLogToken tag in the feed like this: 
{{<chemistry:changeLogToken 
xmlns:chemistry="http://chemistry.apache.org/";>someToken</chemistry:changeLogToken>}}

OpenCMIS based servers send this automatically. 

> ChangeEvents.getLatestChangeLogToken returns null in Atompub binding

>                 URL: https://issues.apache.org/jira/browse/CMIS-872
>             Project: Chemistry
>          Issue Type: Bug
>          Components: opencmis-client
>    Affects Versions: OpenCMIS 0.12.0
>         Environment: Windows 64 bits, JDK 1.7 update 60
>            Reporter: Vincent Tang
>              Labels: getContentChanges
>
> Our test code is like
>         ChangeEvents changeEvents = 
> session.getContentChanges(latestChangeLogToken, false, 25;
>         
>         String newlatestChangeLogToken = 
> changeEvents.getLatestChangeLogToken();
>         assertNotNull(newlatestChangeLogToken);
> But ChangeEvents.getLatestChangeLogToken returns null. I looked at the 
> response feed. I cannot figure out which part is missing. Can you tell from 
> which field OpenCMIS Client API reads the latestChangeLogToken in the feed?
