Hi Jiri,
Here is the sample process that I created using Web Designer whihc allows multiple incoming connection to Script tasks, but when I deploy it, it doesn't work and this process can't even be opened in Eclipse designer. I have tried with converging gateway and it is loading the process into knowledge base.
