How to get workflow instance Id

[Ivano Carrara, geändert vor 12 Jahren.]

Hi all,

Using Liferay's workflow framework, I'm building a portlet that create an asset and start the workflow process to approve it.
In some circumstances I need to assign this process to a certain portal's user.

So, after I call the WorkflowHandlerRegistryUtil.startWorkflowInstance() method, I need to use the WorkflowTaskManagerUtil.assignWorkflowTaskToUser() method to assign the task to a certain UserId.

The problem is that I'm not able to find the WorkflowTaskId to assign ....

Please, there is someone that can help me to find the WorkflowTaskId of the just started process?

Thank you in advance!

Ivano C.

HI.
Use following service to get workflowInstanceId

WorkflowInstanceLink workflowInstanceLink= WorkflowInstanceLinkLocalServiceUtil.getWorkflowInstanceLink(companyId, groupId,AssetClassName, AssetEntryClassPk);
long workflowInstanceId= workflowInstanceLink.getWorkflowInstanceId();

This May help you.

HI ivano,
I think so you are forgetting to pass workflowContext object in that method and that one is important .
and also i would like to suggest you that use workflow definition to assign the task .

Hi Mahendra ,

In the class EditWorkflowAction.java of Liferay, in the method assignTask they pass the null value as workflowContext parameter, the same I'm doing.

In fact in the workflowInstanceLink object there isn't the workflowContext field, so I can't get it...

And ... I don't understand what you are suggesting me... to use the workflow definition to assign the task ... Please could you help me to understand?

Thak you in advance!

Hi Ivano,
I thought that you are applying workflow on custom assets thats way I suggest you use workflow defination to assign task from one user two other user.
i am using workflow defination to assing task,accepting the task,rejecting the task etc and its simple .xml file.
In that you have to generate one .xml (Workflow defination) file and have to apply on your assets.in this xml you can define task as per the roles then liferay will manage to assign it.
Regards,
Mahendra.

Hi Mahendra Mahakle

I found this forum after a long search. I hope this can give actually what i want. I am using remote jbpm workflow in my custom portlet. used the drools guvnor for the workflow design. I can pass the form parameters to the workflow successfully by using the workflowContext object. Now coming to my problem. After the workflow started i can't find the instance id in the workflowwebinstance table all other details are there but this return parameters are empty there. so that i can't find any workflow task in the Task assigned to my roles section and i am getting an exception because of this,
