[jira] [Resolved] (JENA-54) TDB dynamic datasets causes property paths not to work.

     [ https://issues.apache.org/jira/browse/JENA-54?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Andy Seaborne resolved JENA-54.
-------------------------------

    Resolution: Fixed

Fixed in SF SVN for TDB.

The fix is to switch to a special dataset for dynamic dataset queries, not query rewriting. See class in TDB : DynamicDatasets.

Switching back to query rewriting would be ideal: need to pass a alternative default graph to QueryEngineMain, which might have other implications.

The current "special dataset" will work on any data storage layer.

> TDB dynamic datasets causes property paths not to work.  They do work with union default graph.
> Appears to be that the combination of quad rewrite, dynamic datasets and property paths menas the evaluation is not across the dynamic default graph.
