a question about inclusive gateway
I have defined process as followed，
According to the process variable, it can be chosen either via a or b to entry. Only when the both are completed, it will leave the DD node to EE node.
But error pop up while doing the process validation,
Use the inclusive gateway as the Gateway, as per below picture
It can be used as split or merge, due to only all the branches completed then it can leave DD to EE, so we need to chose inclusive gateway, but I have no idea why it get error, please advise.
