Issue seems related to ACTIVITI-355 where the historic process instance query now supports “includeProcessVariables”, but the normal process instance query API (/api/enterprise/process-instances/query) does not, whereas it does support the parameter in the corresponding engine API call (/api/query/process-instances). The customer has no way to display a list of process variables when running Enterprise REST call /api/enterprise/process-instances/query
Steps to reproduce
- Login to activiti-admin, select the Instances tab and locate a running process instance, which contains at least 1 process instance variable. Copy the process instance id. e.g. 2506. NOTE: If you can´t locate a running instance with a process variable, you would have to start any process and could add a process variable via activiti-admin
- Open POSTMAN (or any RESTful client) and fire below calls:
- Enterprise API call get list of process-instances -> /api/enterprise/process-instances/query
(a) Without specifying the “includeProcessVariables” parameter in request body, empty variables bracket will be returned.
Request
POST http://localhost:8080/activiti-app/api/enterprise/process-instances/query { "processInstanceId":"2506" }
Response
{
"size": 1,
"total": 1,
"start": 0,
"data": [
{
"id": "2506",
"name": "myprocess",
"businessKey": null,
"processDefinitionId": "testProcesWorkspace:1:4",
"tenantId": "tenant_1",
"started": "2018-06-26T14:26:56.632+0000",
"ended": null,
"startedBy": {
"id": 1,
"firstName": null,
"lastName": "Administrator",
"email": "admin@app.activiti.com"
},
"processDefinitionName": "testProcesWorkspace",
"processDefinitionDescription": null,
"processDefinitionKey": "testProcesWorkspace",
"processDefinitionCategory": "http://www.activiti.org/processdef",
"processDefinitionVersion": 1,
"processDefinitionDeploymentId": "1",
"graphicalNotationDefined": true,
"startFormDefined": false,
"suspended": false,
"variables": [ ]
}
(b) If attempting to specify “includeProcessVariables” parameter in the request body, it results in an error "JSON parse error: Unrecognized field \"includeProcessVariables\""
Request
POST http://localhost:8080/activiti-app/api/enterprise/process-instances/query { "processInstanceId":"2506", "includeProcessVariables":"true" }
Response
{
"message": "JSON parse error: Unrecognized field \"includeProcessVariables\" (class com.activiti.model.runtime.dto.ProcessInstanceQueryRepresentation), not marked as ignorable; nested exception is com.fasterxml.jackson.databind.exc.UnrecognizedPropertyException: Unrecognized field \"includeProcessVariables\" (class com.activiti.model.runtime.dto.ProcessInstanceQueryRepresentation), not marked as ignorable (8 known properties: \"size\", \"start\", \"processDefinitionId\", \"sort\", \"page\", \"state\", \"processInstanceId\", \"appDefinitionId\"])\n at [Source: (PushbackInputStream); line: 3, column: 32] (through reference chain: com.activiti.model.runtime.dto.ProcessInstanceQueryRepresentation[\"includeProcessVariables\"])",
"messageKey": "GENERAL.ERROR.BAD-REQUEST"
}
c) however, running the equivalent Engine API call allows querying for process-instances with the "includeProcessVariables" parameter in the request body and returns instances including their variables.
Request
POST http://localhost:8080/activiti-app/api/query/process-instances { "processInstanceId":"2506", "includeProcessVariables":"true" }
Response
{
"size": 1,
"total": 1,
"start": 0,
"data": [
{
"id": "2506",
"name": "myprocess",
"businessKey": null,
"processDefinitionId": "testProcesWorkspace:1:4",
"tenantId": "tenant_1",
"started": "2018-06-26T14:26:56.632+0000",
"ended": null,
"startedBy": {
"id": 1,
"firstName": null,
"lastName": "Administrator",
"email": "admin@app.activiti.com"
},
"processDefinitionName": "testProcesWorkspace",
"processDefinitionDescription": null,
"processDefinitionKey": "testProcesWorkspace",
"processDefinitionCategory": "http://www.activiti.org/processdef",
"processDefinitionVersion": 1,
"processDefinitionDeploymentId": "1",
"graphicalNotationDefined": true,
"startFormDefined": false,
"suspended": false,
"variables": [
{
"name": "initiator",
"type": "string",
"value": "1"
},
{
"name": "contractNodeEntry",
"type": "string",
"value": "test"
}
]
}
Expected Behavior
Variables are listed in the response similar to a historic query 'api/enterprise/historic-process-instances/query' using the "includeProcessVariables" parameter set to "true" in the query request body.
Actual Behavior
Process Variables are never listed in the 'api/enterprise/process-instances/query' call response and the "includeProcessVariables" parameter is an unrecognized field.
