<p><font size="4">Hi everybody! <br>
<br>
I'm struggling with the forEach construct. We already had a Drools Flow <br>
running using Drools 5.0. <br>
Now we would like to port it to Drools Flow 5.1.1. <br>
<br>
It seems that there is a problem with the ForEach Construct in combination <br>
with the XOR Gateway (the same <br>
seems to be true for the OR Gateway): <br>
<br>
Even if i set both constrains of the gateway to "eval( true )" i got an <br>
runtime Error like (full Stacktrace at the end of my post): <br>
Caused by: java.lang.IllegalArgumentException: XOR split could not find at <br>
least one valid outgoing connection for split Art des Arbeitsanstosses <br>
pruefen <br>
<br>
I can even reproduce this behaviour when building a small workflow from <br>
scratch. <br>
Had anyone else such an error? Does anyone know a workaround for this? <br>
You can reproduce this with the attached Flows.</font><br>

Any help is really appreciated! <br>
Regards, <br>
Dirk Hermanns <br>
<br>
P.S.: If i try to build such an Flow using the new bpmn Notation, i get an <br>
error when building the package in Guvnor: Workitem Node xxx has no <br>
incoming connection. <br>
So this doesn't seem to help :(. Has anyone got the forEach (or Multiple <br>
Instances) feature with Drools 5.1.1 working? <br>
