The problem occurs in this situation:
- When rendering a preview and for this preview a subtree query is performed, the preview fails.
Sorry, that this probably not the info you can use for testing. The problem came for us in a customized code part - so we even not sure if a testcase can be performed on a standard eZ Intallation.
So e.g. this szenario should fail:
- You have an article, the article displays objects from it's subtree (e.g. a list of "subarticles")
- The preview should now fail for such an article, bec. the subtree query fails
but not sure if you can mirror this scenario.
