Hi,
I am trying to create a BPMN file using fluent API and had hit an issue. This is pretty similar to the invoice approval example in github
The issue seems to be that we cannot connectTo to an elementId that we can already connected in a previous moveToLastGateway.
I had created the similar model via the Camunda Modeler and it works fine.
This is the code I am trying to build
BpmnModelInstance modelInstance = Bpmn.createExecutableProcess("invoiceApproval")
.name("Invoice Approval Process")
.startEvent()
.name("Invoice Created")
.userTask()
.id("accountantReview")
.name("Accountant Review")
.camundaAssignee("accountant")
.userTask()
.name("Approver Level 1 Approval")
.camundaAssignee("approvalLevel1")
.exclusiveGateway()
.id("approve1")
.name("Approval 1")
.gatewayDirection(GatewayDirection.Diverging)
.condition("Approved", "#{approved}")
.userTask()
.name("Approver Level 2 Approval")
.camundaCandidateGroups("approvalLevel2")
.exclusiveGateway()
.id("approve2")
.name("Approval 2")
.gatewayDirection(GatewayDirection.Diverging)
.condition("Approved", "#{approved}")
.endEvent()
.name("Invoice Fully Approved")
.moveToLastGateway()
.condition("Return", "#{not approved}")
.connectTo("accountantReview")
.moveToLastGateway()
.condition("Return", "#{not approved}")
.connectTo("accountantReview")
.done();
The exception is:
