Webservices query issue: InvalidNodeRefException

[rludvig]

I am using the Alfresco web services client (from the SVN) to execute a query on an Alfresco Open Source (release 1.0) and get this exception (regardless of the query):

org.alfresco.service.cmr.repository.InvalidNodeRefException: Node does not exist: workspace://SpacesStore/53fa857e-66bd-11da-87cf-990918e1d71a

I checked and the specified node is indeed absent from the mysql Node table. OTOH, the exact same client and query work fine on another Alfresco instance (release 1.1.2).

Does this mean that the web service client is not compatible with an older version of Alfresco, or is the repository on the 1.0 instance corrupted ??

I believe that there was a signficant change to the way content web-services work from 1.0 to 1.1 - so they are not backward compatible. The change was important enough that we felt that it was needed even if it broke compatability - which is why we made the change as early as possible.

Applogies if this causes you problems.

Thanks,

Kevin

I understand, but is there a point from which on you will commit to keep the wsdl and xsd definitions compatible, in order to avoid a similar situation in the future ?? I see there are quite a few areas of research in the web service section (most notably ws-security and cql), and am therefore cautious to invest effort in any development surrounding the ws interface.

[kevinr]

Indeed I agree! We hope that the only major change was this one - other than that it should just be new methods and new services and fixes to broken ones.

Thanks,

Kevin

I just upgraded from 1.0 to 1.1.2 using the instructions (in the sticky thread) and the same exception occurrs. Are there any other instructions for the upgrade operation or is this a problem with lucene's indexes that cannot be fixed with an upgrade ??
