How can i Achieve backward flow

himabindu_v — Thu, 26 Jul 2018 13:08:12 GMT

For ex:User Task is consider as level1 and level2 , if level1 is approved then it goes to level2.if level2 is rejected i have to forward user task to level 1.How can i achieve this scenario, could you please let me know.

It sounds like you need an exclusive gateway after level1. The level1 task should set a variable of approved/rejected. The outgoing sequence flows of the exclusive gateway can have conditions of approved, which should go to level2, or rejected, which should go back to level1.

Yes i need exclusive gateway if you had any examples on this requirement could you please let me know

Actually my intention was the level1 task approved, which should go to level 2. when level2 task rejected it will again go back to level1 task. that is the scenario, if you had any solution on this scenario could you please let me know.

you can refer this example act activiti source code Activiti/ExclusiveGatewayTest.testDecisionFunctionality.bpmn20.xml at 6.x · Activiti/Activiti · GitHub if you are uisng activiti. Just import this xml file using activiti-processes-> import process from your activiti 6 designer.

i am implementing the above scenario using Spring frame work with activiti. if you had any solution for this scenario,could you please let me know.

Below scenario i want to achieve using Spring framework with Activiti, Any one did the same scenario like this could you please share your examples to me.

Do you mean you're using the full activiti 6 app in tomcat like in http://www.baeldung.com/activiti-kickstart-and-rest-apps ? Or perhaps you're using v5 and the Activiti explorer (in which case the book Activiti in Action is probably the best reference)?

Or are you embedding activiti in a spring boot app like in Getting started with Activiti and Spring Boot ?

If you're embedding activiti then you'll need to add your own UI. If you're using the v6 app or the v5 explorer app then you should have a task-processing UI available and you'd just need to import your process.

i am embedding activiti in a spring frame work, i am created BPMN file like below file.I am uploading the Bpmn file for this scenario. level1 approved successfully and level2 rejected the task, then task again will go to level1 it is not happened thorugh Spring with activiti.

What you describe in words and what you've shown in your diagram do not match as far as I can seen. From your description I would expect something like this:

Perhaps you need to review your diagram?

Re: How can i Achieve backward flow

himabindu_v — Fri, 27 Jul 2018 09:34:32 GMT

i am sorry, am explained clearly to you.

1.level1 manager approves it shoulld go to level2 manager, if level1 manager rejects then the task should be complete.

2.if level2 manager approves then the task should complete, if level2 manager rejects then the task again redirect to level1 manager.

i hope you are able to understanding my problem.

Re: How can i Achieve backward flow

ryandawson — Fri, 27 Jul 2018 09:50:50 GMT

Ok it does look like your diagram should do that. So your problem is "level1 approved successfully and level2 rejected the task, then task again will go to level1 it is not happened thorugh Spring with activiti"

So level1 is working as you would expect and using the outcome to decide the next step but level2 is not? What conditions do you have set on the outgoing sequence flows and what variable are you using for the condition in the xml of your process definition? I'd recommend looking at Getting started with Activiti and Spring Boot and how that example sets the "telephoneInterviewOutcome variable as the exclusive gateway uses it to route the execution"

himabindu_v — Fri, 27 Jul 2018 10:16:09 GMT

yes level1 is working fine what i am expected, level2 is also working fine when level2 is approved the task.

My problem is level2 is rejects it should go to level1 manger, for this problem what can i do.

I already read this blog (Getting started with Activiti and Spring Boot ).

In this blog they are showed only in forward way not backward way.

Thank you.

It doesn't really matter whether it is going forward or backward. The question is whether the value of the variable that is being checked in the sequence flow matches the condition. Anything you could share of the xml and java would help.

What is the condition you are checking for both the outgoing transactions of second exclusivegateway (i.e after the Accountant Approval). If you could share the .bpmn file it will give clear idea of what you are missing.

Your diagram seems to be fine, what you are missing here is are you setting the variable properly and the condition check on outgoing sequence flow.

Thank you Ryan Dawson, for giving suggestions to me. I am added one variable for flow for backward and forward.Now it's working fine.
