Question

Reg Error : Two or more nodes are in a loop and will not be started.

Hi All,

I am trying to save and publish my process model, but it throws the following error,

This process model could not be published due to the following errors. Please correct them before continuing.

  • Two or more nodes are in a loop and will not be started.

Reason behind this error:

  • I have configured my interface as start form so that I can use that process model in site.
  • And I have one sub process, if we receive the output button value as "Back" from sub process, then it should again show the start form, so I have connected sub process  node again to start form node by using gateway.

So instead of doing this, can you please suggest me the correct way to sort this issue.

Thanks in advance.

    A start node can't have any incoming process flow; a start form can't be re-executed under any circumstances.  If you need to loop back to a certain interface, it will need to be added to a User Input Task, which you can loop back to as many times as you'd like.

    You can use the same interface in a start form as well as in a user input task.

    For what it's worth: i personally almost never use the "configure process model as site page" feature.  It's just not very flexible and not very useful for me.  I strongly prefer allowing a user to click into a process model if they want to, providing a "start process link" setup in a site page interface (which usually has other things on it as well).  Thus I almost never configure a process model with a start form, preferring instead to chain the user directly to the first User Input Task in the process model, which works seamlessly (and assuming you set things up correctly, again provides quite a bit more flexibility).
