Hi, Currently we are in the process of implementing the correlation support for for BPMN process instances.
This correlation request will resume the execution of a particular process instance based on the provided variable values. Correlation request can be accessed by using following json request ( XML also supported ) POST https://localhost:9443/bpmn/runtime/recieve { "processDefinitionKey":"oneTaskProcess", "activityId": "messageintermediatecatchevent3", "messageName":"startMessage", "signalName":"signalName", "action":"messageEventReceived", "messageName":"startMessage", "variables": [ { "name" : "myVariable", "value" : 1234, "operation" : "equals", "type" : "long" } ], "correlationVariables": [ { "name" : "myVariable", "value" : 1234, "type" : "long" } ], "processInstanceVariables": [ { "name" : "processVariable", "value" : "some string", "operation" : "equals", "type" : "string" } ] } This json request consists following parameters. *processDefinitionKey/processDefinitionId/messageName* (compulsory) Either one relevant property out of three should be specified in the request. *activityId *(optional) This property is required when there are more than one receivers waiting for the same message/signal in different execution flows. In the above process flow, all three or two of the execution flows might be waiting for the same message. *action *(compulsory) actions can be either messageEventRecieved/signalEventRecieved/signal. *signalName* (optional) If we have any signal related actions, then *signalName* has to be specified. *variables* (optional) This holds the task specific local variables that can be used to query and filter the relevant process instances. *processInstanceVariables* (optional) All the instance variables except correlation variables can be mentioned here. *correlationVariables* (compulsory) All the correlation variables should be mentioned here. By default it performs the equal operation of that variables. *variables* and *processInstanceVariables *can be used to speed up the querying process and the correlation variables should be unique across the process instances. Any suggestions/ideas are welcome. Regards, Firzhan
