Kaleo middle state

[Rajmund Bocsi, modificado hace 11 años.]

Hello,

I try to create a simple workflow with Kaleo Forms for Java (in the Liferay Developer Studio). I use Liferay 6.1 EE GA2.

Here's the image:

and the xml:

When I try to upload the xml to the liferay, the portal says: "An error occured in the workflow engine" with no further explanations in the console log. However, If I remove the reject1 and reject2 state nodes, the uploads is successful. I read somewhere, that kaleo no longer support multiple termination states, but it seems kaleo no longer supports more than two states (initial and termination) either. Is that true?

I face the same problem.How to slove this problem?

[Rajmund Bocsi, modificado hace 10 años.]

I don't. We decided to doing the project without workflow engine. Sorry.

Hi,

The terminal state of the workflow should be the last state in the xml. Otherwise the parsing will fail.
