How to read content of old versions?

jtorres — Fri, 01 Dec 2006 08:22:34 GMT

Hi people:I've seen how to recover the version history and how to revert to a previous version, but how can I recover the content of the previous versions to see it before I revert the node?Thanks.

Still no solution found :-(. The history nodes has an UUID, however they can't be recovered as a normal node, so I can't read the content. The only operation allowed is revertVersion, but before doing a revert operation is really needed to be able to read the content of every version.

Hi,

The reference found in the version history is a reference to the forzen state for that version.

This reference can be used like any other reference to a node and thus can be passed to the content service to retrieve the content of that node at that version.

Cheers,
Roy

I've 2 references information:

- frozenNodeId: it's the UUID of the original content, if I try to get content of this UUID I obtain the content of the actual version.
- node-uuid: this one is different, but if I try to get the content of this one produces a data not found error.

What is the reference I need to use and how it has to be used?

Thanks for your help Roy :wink:
