"This type of node cannot have more than one incoming connection!" beginner question

[ingmarhaasdijk]

Hello JBoss Community,

For a course that I follow on my University I have to create a simple model that works in the jbpm console/KIE workbench. The model is used to enter simple information about a manuscript and using boolean data to see where the model has to go. I followed these movies to see how it could be done, but now I receive several of the same errors when I try to build & deploy the project. Enclosed you find a screenshot of the model en the errors that are given. The errors are:

unable to parse xml : Exception class java.lang.IllegalArgumentException : This type of node cannot have more than one incoming connection!

Does somebody know how I can fix these errors and get my model working? Remember that I am very new to using this software and I wasn't really capable of finding good tutorial material.

Kind regards,

Ingmar Haasdijk

The End node would not allowed more than one connection. Use converging gateways for more than one connection

EDIT:

I removed the redirection to the step 'Review manuscript' and the errors were gone and the build was successful.

But I do need the model to redirect to that step, so can anyone tell me how I can do that?

/EDIT

Thanks for your reply! I removed the multiple connections, created end nodes for all and tried it, but with the same errors (2 this time).

Then I connected the end nodes with gateways, but this again gave me 3 errors. See the screenshots below.

What am I doing wrong?

The 'Review manuscript' node cannot have more than one incoming connection. You change the connection from 'Verzamel Reviewers' to 'Review manuscript' , ie, you should give the connection from 'Verzamel Reviewers'   to the converging gateway.

If you have more than connection to a node, you should use converging gateway and the connection from  the converging gateway to the node.

HTH

That did the trick, thank you!
