Ian (Dunlop) has been looking at such a method. It is not in Taverna 2.0. The current inability in going back from a "URI" form of the reference to a T2Reference and so to the data, is the main reason why intermediate results did not make it into the Taverna 2.0 release. Aside: The "URI" string will change so that the values are unique, it has a more usual form, and is resolvable. > Also, my workflow execution driver calls this method at the end of a > workflow execution, which is a method in a *ResultListener* > implementation, to show me the results: [snip] > I get an exception: > net.sf.taverna.t2.reference.DaoException: Key > t2:list//testNamespace?test44/false/2 not found in store > and I am not sure why the data has not been registered during execution? I don't know. If the data has been registered, and it must(?) have been to get the T2Reference, then you should be able to render the T2Reference. If you are doing this in Taverna Workbench, can you check that in the results perspective, you are able to browse the results and see the value for that "URI"? > thanks for the help, > -Paolo Alan > ------------------------------------------------------------------------------ > _______________________________________________ > taverna-hackers mailing list > [email protected] > https://lists.sourceforge.net/lists/listinfo/taverna-hackers > Developers Guide: http://www.mygrid.org.uk/usermanual1.7/dev_guide.html > FAQ: http://www.mygrid.org.uk/wiki/Mygrid/TavernaFaq ------------------------------------------------------------------------------ _______________________________________________ taverna-hackers mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/taverna-hackers Developers Guide: http://www.mygrid.org.uk/usermanual1.7/dev_guide.html FAQ: http://www.mygrid.org.uk/wiki/Mygrid/TavernaFaq
