Workflow gets struck at XOR gate. I am just comparing between 2 integer variable

Workflow gets struck at XOR gate. I am just comparing between 2 integer variables as a condition. I am really unable to find the reason for it. Log shows the following error message.
016-04-11 10:12:29,099 [Appian Work Item - 18994 - ProcessExec01 : UnattendedJavaActivityRequest] ERROR com.appiancorp.util.BundleUtils - Cannot retrieve the value for key "address.processDesigner.displayName" from the bundle.
Any one please help.

I still think this is a bug as I'm pretty sure it breaches the BPMN specification. Still, the workaround of merging the flows using a script task works just fine.

Sarat, Open expression editor of XOR gate and check whether your condition is within double quote"". If yes, then It becomes string and this will not work for integer.

No double quotes... I am checking between 2 integer variables if pv!one_Integer=pv!two_Integer

Is there more than one input to the XOR node? If so and it is in a loop it will hang us the second time around. If that is the problem use an empty script task to consolidate inputs before the XOR.

Yes. There are 2 inputs to XOR. And it is failing in second time of loop. But i did nto understand the "empty script task" solution that you proposed?

take the two separate input lines and make them inputs to a script task, then just one line from script task to XOR.

Wow! It worked. Simple solution but powerful. I didn't know about this weird behavior of XOR. Thank you so much Robins.

When a looped flow enters an OR or an XOR gateway, the gateway pauses after the first instance token passes through – until all other incoming flows arrive.
