Variables in a sub process

walterjs — Thu, 07 Jul 2011 08:23:33 GMT

I have a simple approval sub process that can have multiple instances created at a time. I want to use the result of the approval in the parent process. As soon as anybody rejects, all other instances are destroyed and the process is rejected. Basically it needs 100% approval by everybody. This all

embedded subprocesses share the same variable context as the parent process instance, wo why do you need to set them explicitely?

If I do not do this, the parent process knows nothing about the "decision" variable.

I get an "Unknown variable used in expression" exception.

embedded subprocesses share the same variable context as the parent process instance, wo why do you need to set them explicitely?

So, if this is true, I should never get the above exception and I also have to worry about concurrency when I have a multi-instance sub-process as the last sub-process to set the variable will overwrite any previous value and different sub-processes would constantly be overwriting each other's values.

That will depend on how you configure your multi instance (sequential will try to reuse the execution).

If you can put it in a unit test, I can better understand what you are trying to do.

Ah, ok. I understand your previous post now. The sub-process is not running sequentially, so therefore it will not use the parent execution.

My question really was just if there was a way to output variables from an embedded sub-process like with a call activity so that I didn't have to add the service task to set the variable. If not, I will make do with the service task.

I will submit a unit test today hopefully.

Thanks

Hi I am unable to return a variable from the subprocess to its parent process .I am using a call activity to sequentially call a process and on rejection inside the subprocess i want to terminate the main processs
