In the On Block Error action one can either continue flow, in which case one can chose a continuation option from a dropdown or throw an error. If one chooses to throw an error, one can chose to run a subflow. In the subflow case, where does execution continue after the subflow? End of block? In the subflow can one chose a Go To Label that is in the main block?.

You can run a sub-flow regardless of whether you choose to throw an error or continue the flow. If you set the block to throw an error, it will do just that - it will throw an error, which means the flow will stop (unless your block is within another block that can handle the error).

If you want the flow to continue after calling the sub-flow, you should just make it run the sub-flow and then continue the flow run.

Hi @Agnius
please clarify. If I continue the flow, there is no option in the dropdown to run a subflow. It seems the only way to do that is to throw an error. If I throw an error and go to a subflow, where does the subflow return execution to? End of Block?

Again, if you set it to throw an error, it will stop the entire flow. It will not end up anywhere outside the block. It will stop completely. If you have it call a sub-flow, the sub-flow will be called, but once it returns from the sub-flow to the block, it will stop the flow.

Here's a sample of a block that is set to continue the flow run after calling a sub-flow:

I'm not sure why you would think you cannot call a sub-flow when you set your block to continue the flow.

Hi @Agnius
I didnt realize that I could add a rule to Log to a file if I was continuing the flow. I thought I could only add a rule if I through an error. So now I understand. Thank you
