How to get the content of a specified revision using the slide api?

Hi all,

 

I currently have the problem to access the content of a node using a
specified revision. If I simply do the following:

 

token.begin();

NodeRevisionDescriptors nrds =
token.getContentHelper().retrieve(slideToken, "/files/test.xml");

NodeRevisionDescriptor nrd =
token.getContentHelper().retrieve(slideToken, nrds, new
NodeRevisionNumber("1.7"));

token.rollback();

 

I'll get the following Exception:

 

org.apache.slide.content.RevisionDescriptorNotFoundException: No
revision descriptor found on object /1150222013006.1348

If I want to enumerate all existing revisions via:

 

Enumeration ern = nrds.enumerateRevisionNumbers();


while( ern.hasMoreElements() ) {

      NodeRevisionNumber nrn = (NodeRevisionNumber) ern.nextElement();

      System.out.println( "Revision: " + nrn.toString());

}

 

 

I'll get the following output:

 

Revision: 0.0

Revision: 1.0

 

 

However, if I use the Webdav-ClientAPI or tools like DAVExplorer, all
node revisions are present and the Revision called 1.7 is available too!

 

Is there anybody who can help me?

 

 

Many thanks in advance.
