Issue with a text variable with multiple values set using REST

marco_altieri — Sun, 29 Apr 2018 18:09:01 GMT

I am using the following rest call to start a new processOST /api/enterprise/process-instancescurl 'http://localhost:9080/activiti-app/api/enterprise/process-instances' -H 'Authorization: Basic YWRtaW46cGFzc3dvcmQ=' -H 'Content-Type: application/json' -H 'Accept: application/json' --data-binary $'

I think Assignees will hold the user(s) to whom the task was assigned to. In your case, the task was with the group which I think was the reason for it being null.

What type is "assignees": ["2018", "2013"] ? defined in your process variables?

I can see that is marked as serializable.. but you probably want to define it as an String[] or a list of strings.

Hi Mauricio,

the type of the variable assignees was "text".

It works well if I pass only one value. It doesn't work only when I pass an array.

Thanks

Marco

Serialized data is not returned by this API involving forms! If you set the property rest.variables.allow.serializable=true, you can use the core engine API and get the link to the variable in response. eg:

Request

curl 'http://localhost:8080/activiti-app/api/runtime/process-instances?tenantId=tenant_1' -H 'Authorization: Basic YWRtaW5AYXBwLmFjdGl2aXRpLmNvbTphZG1pbg==' -H 'Content-Type: application/json' -H 'Accept: application/json' --data-binary $'{"variables": [{ "name": "assignees", "value": ["2018", "2013"]}],"processDefinitionId":"serialize:2:132549", "returnVariables":true}' --compressed

Response

{"id":"132616","url":"http://localhost:8080/activiti-app/api/runtime/process-instances/132616","businessKey":null,"suspended":false,"ended":false,"processDefinitionId":"serialize:2:132549","processDefinitionUrl":"http://localhost:8080/activiti-app/api/repository/process-definitions/serialize:2:132549","processDefinitionKey":"serialize","activityId":"sid-11AC2671-8E15-45AF-9103-E6EC6D7F6865","variables":[{"name":"initiator","type":"string","value":"1","scope":"local"},{"name":"assignees","type":"serializable","value":null,"valueUrl":"http://localhost:8080/activiti-app/api/runtime/process-instances/132616/variables/assignees/data","scope":"local"}],"tenantId":"tenant_1","name":null,"completed":false}‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍
