Hi Chris, There are problems with the actor tree in Kepler. I updated to the svn head and do not see any actors, or the provenance recorder. I then updated to revision 19343, as suggested by Derik in a recent email, and the actors are there, but no provenance recorder... What revision are you using?
Do you see a green button with a "P" in the toolbar? If so, provenance is enabled and will write to an HSQL database in .kepler/provenance/. --dan Chris Weed wrote: > I am trying to run the provenance recorder as described here: > https://kepler-project.org/developers/interest-groups/provenance-interest-group/provenance-recorder-instructions > > When I drop the provenance recorder into the workflow desktop I get > the following: > > com.microstar.xml.XmlException: Cannot create entity without a class > name. in [external stream] at line 2 and column 29 > at ptolemy.moml.MoMLParser._checkForNull(MoMLParser.java:3784) > at ptolemy.moml.MoMLParser._createEntity(MoMLParser.java:3965) > at ptolemy.moml.MoMLParser.startElement(MoMLParser.java:2486) > at com.microstar.xml.XmlParser.parseElement(XmlParser.java:921) > at com.microstar.xml.XmlParser.parseContent(XmlParser.java:1104) > at com.microstar.xml.XmlParser.parseElement(XmlParser.java:924) > at com.microstar.xml.XmlParser.parseContent(XmlParser.java:1104) > at com.microstar.xml.XmlParser.parseElement(XmlParser.java:924) > at com.microstar.xml.XmlParser.parseDocument(XmlParser.java:481) > at com.microstar.xml.XmlParser.doParse(XmlParser.java:159) > at com.microstar.xml.XmlParser.parse(XmlParser.java:132) > at ptolemy.moml.MoMLParser.parse(MoMLParser.java:1395) > at ptolemy.moml.MoMLParser.parse(MoMLParser.java:1368) > at ptolemy.moml.MoMLParser.parse(MoMLParser.java:1523) > at ptolemy.moml.MoMLChangeRequest._execute(MoMLChangeRequest.java:270) > at ptolemy.kernel.util.ChangeRequest.execute(ChangeRequest.java:170) > at ptolemy.kernel.util.NamedObj.executeChangeRequests(NamedObj.java:699) > at ptolemy.kernel.util.NamedObj.requestChange(NamedObj.java:1686) > at ptolemy.actor.CompositeActor.requestChange(CompositeActor.java:1351) > at > ptolemy.vergil.basic.EditorDropTarget$DTListener.drop(EditorDropTarget.java:448) > at java.awt.dnd.DropTarget.drop(DropTarget.java:430) > at > sun.awt.dnd.SunDropTargetContextPeer.processDropMessage(SunDropTargetContextPeer.java:500) > at > sun.awt.dnd.SunDropTargetContextPeer.access$800(SunDropTargetContextPeer.java:53) > at > sun.awt.dnd.SunDropTargetContextPeer$EventDispatcher.dispatchDropEvent(SunDropTargetContextPeer.java:812) > at > sun.awt.dnd.SunDropTargetContextPeer$EventDispatcher.dispatchEvent(SunDropTargetContextPeer.java:736) > at sun.awt.dnd.SunDropTargetEvent.dispatch(SunDropTargetEvent.java:29) > at java.awt.Component.dispatchEventImpl(Component.java:3926) > at java.awt.Container.dispatchEventImpl(Container.java:2068) > at java.awt.Component.dispatchEvent(Component.java:3903) > at > java.awt.LightweightDispatcher.retargetMouseEvent(Container.java:4256) > at > java.awt.LightweightDispatcher.processDropTargetEvent(Container.java:4007) > at java.awt.LightweightDispatcher.dispatchEvent(Container.java:3861) > at java.awt.Container.dispatchEventImpl(Container.java:2054) > at java.awt.Window.dispatchEventImpl(Window.java:1801) > at java.awt.Component.dispatchEvent(Component.java:3903) > at java.awt.EventQueue.dispatchEvent(EventQueue.java:463) > at > java.awt.EventDispatchThread.pumpOneEventForHierarchy(EventDispatchThread.java:269) > at > java.awt.EventDispatchThread.pumpEventsForHierarchy(EventDispatchThread.java:190) > at java.awt.EventDispatchThread.pumpEvents(EventDispatchThread.java:184) > at java.awt.EventDispatchThread.pumpEvents(EventDispatchThread.java:176) > at java.awt.EventDispatchThread.run(EventDispatchThread.java:110) > > Chris > _______________________________________________ > Kepler-users mailing list > Kepler-users at kepler-project.org > http://mercury.nceas.ucsb.edu/kepler/mailman/listinfo/kepler-users >
