Task State to filter WorkflowInstanceQuery

dave984

In my activity bmpn i have some states such as "Start Process", "Review", "Second Review" and so on…
When i start the Workflow in Share i can navigate it through all states.
Now, how can i retrieve the current state in my custom webscript?
Here some code:

WorkflowInstanceQuery workflowInstanceQuery = new WorkflowInstanceQuery();
   
// get filter param values
Map<QName, Object> filters = new HashMap<QName, Object>(9);
if (req.getParameter(PARAM_TASK_STATE) != null){
     filters.put(??????????, req.getParameter(PARAM_TASK_STATE));
}
workflowInstanceQuery.setCustomProps(filters);
workflows.addAll(workflowService.getWorkflows(workflowInstanceQuery));
‍‍‍‍‍‍‍‍‍‍‍

For example for the Review and Approve basic Alfresco's workflow the state i'm trying to retrieve are "Start Review", "In Review", "Approved", "Rejected"…
Someone have an idea?!

Param values added to customProps map will be parse as activiti global variable.
So if you had added PARAM_TASK_STATE into process instances global variable in you workflow,you can query using customProps

I have received message from Kaynezhang !

This is his solution , and my problem has resolve .

The brief process is like below:
1.Whenever state changing task such as "Start Review", "In Review", "Approved", "Rejected" is executed,persiste process variables (for example PROCESS_STATE) into database.

execution.setVariable("PROCESS_STATE",state);

2.Get workflow instances according to the state(global variables)

WorkflowInstanceQuery workflowInstanceQuery = new WorkflowInstanceQuery();

Map<QName, Object> customProps = new HashMap<QName, Object>(9);

workflowInstanceQuery.setCustomProps(customProps);

workflowService.getWorkflows(workflowInstanceQuery);
