ExecutionService.setVariable() Question

yongtao Oct 1, 2010 3:04 PM

Hi,

We are using jBPM 4.3. We start the process execution by

ExecutionService.startProcessInstanceByKey(key, variables);

Half way through the workflow we want to modify one of the variables, say X, so that the remaining steps will pickup the new value. We tried:

ExecutionService.setVariable(executionId, "X", "new value");

That didn't work. In the remaining steps of the workflow we still see the old value of X.

What did we do wrong? Any advice?

Thanks!

Yongtao

Hi Yongtao,

Did you re-get the process instance by using executionService.findProcessInstanceById()? The process instance won't synchronize data from database automaticly, Once we modify the process instance, as variable or signaling, we need re-get process instance.

Hope this may be help.

Cheers.

Thanks HuiSheng,

Yes I did re-get the process instance. It did not help.

However, I found a workaround. Instead of calling

ExecutionService.setVariable(executionId, "X", "new value");

I pass a map of variables (and their new values) to the TaskService.completeTask() call. This works just fine for me since I only need those new values in the subsequent steps.

Thanks.
