Sascha Homeier resolved CMIS-1074.
----------------------------------
Resolution: Cannot Reproduce
Weird, today I can no more reproduce that issue
> getContentStream returns null for renditions if link cache is cold
> ------------------------------------------------------------------
>
> Key: CMIS-1074
> URL: https://issues.apache.org/jira/browse/CMIS-1074
> Project: Chemistry
> Issue Type: Bug
> Components: opencmis-client
> Affects Versions: OpenCMIS 1.0.0
> Reporter: Sascha Homeier
> Priority: Minor
>
> A direct request for a rendition stream returns null:
> {code}
> ContentStream contentStream = cmisSession.getContentStream(objectId,
> originalId, null, null);
> // contentStream is null here
> {code}
> Used binding: AtomPub
> I am not sure if I understand the AtomPub binding with its links well enough
> but for me it seems the link cache is cold and the client wants to heat it up
> by getting the main document. This is done by getting the object by id with
> rendition filter "cmis:none". I guess this rendition filter is the reason
> there is no "alternate" link found in link cache which could be used to
> actually request the content stream.
> If you heat up the cache manually by getting the main document including
> renditions first it works:
> {code}
> OperationContext opCtx =
> OperationContextUtils.createMinimumOperationContext();
> opCtx.setRenditionFilterString("*");
> ObjectId objectId = cmisSession.createObjectId(coid);
> Document document = (Document) cmisSession.getObject(objectId, opCtx);
> ContentStream contentStream = cmisSession.getContentStream(objectId,
> originalId, null, null);
> {code}
> Also getting the contentStream via document object works:
> {code}
> OperationContext opCtx =
> OperationContextUtils.createMinimumOperationContext();
> opCtx.setRenditionFilterString("*");
> ObjectId objectId = cmisSession.createObjectId(coid);
> Document document = (Document) cmisSession.getObject(objectId, opCtx);
> ContentStream contentStream = document.getContentStream(originalId);
> {code}
