Hi Joe, I created a simple workflow with EvaluateXPath and managed to repro the issue. Here is the snapshot of the screen. This is on Windows with 0.7.0 snapshot. There is no issue on 0.6.1 on Windows and 0.7.0 on Linux.
We can't roll back to 0.6.1 as we have a dependency on a feature in 0.7.0 Thanks, Keith [cid:36ee5712-5a4f-45cb-847e-3a9234eb4887] ________________________________________ From: Keith Lim <[email protected]> Sent: Wednesday, June 08, 2016 10:28 AM To: [email protected] Subject: Re: Failure when running a workflow created from a template from another NiFi version. Hi Joe, Interesting... I didn't find anything in the nifi-app.log, however, I found these logged in the nifi.user.log. 2016-06-08 10:18:22,089 INFO [NiFi Web Server-20] org.apache.nifi.web.filter.RequestLogger Attempting request for (anonymous) PUT http://nifi.dev.azure.ds-iq.corp:10000/nifi-api/controller/process-groups/658947de-a030-3832-95a6-1f4d2b346131 (source ip: 10.200.0.31) 2016-06-08 10:18:22,089 INFO [NiFi Web Server-20] o.a.n.w.a.c.IllegalStateExceptionMapper java.lang.IllegalStateException: EvaluateXPath[id=6c73cffa-0d34-3b25-94d4-14d115b8b62b] is not in a valid state.

This is the message box I got when I tried to run my workflow: Node azudevmgmt01.ds-iq.corp:10001 is unable to fulfill this request due to: EvaluateXPath[id=6c73cffa-0d34-3b25-94d4-14d115b8b62b] is not in a valid state Thanks, Keith ________________________________________ From: Joe Witt <[email protected]> Sent: Wednesday, June 08, 2016 10:02 AM To: [email protected] Subject: Re: Failure when running a workflow created from a template from another NiFi version. Keith, Can you collect more information on this from the nifi-app.log? Not in valid state should be associated with some exceptions and such that ideally will be in the logs.
