How to call another process ?

[danielbreitner]

Hi Activiti - Folks


I am just starting with your wonderful engine and I am wondering how I can call another process without doing it programmatically ?

Is there a way to do this ?

best regards,

:?:  :?:  :?:  by modelling it?

[danielbreitner]

Yes of course.

But how do I model it ?

There is no such thing as "call another process".
Ans using a subprocess doesn´t seem to work.

Ans using a subprocess doesn´t seem to work.

Why not?

Ok,maybe I should have posted an example:

process A is calling process B, process B is calling process C and process D is also calling process C.
So we have a diagram like this:


A -> B -> C
       D ->

The processes need to be callable by REST, so that they can be triggered from outside.

The only thing that came to my mind was to create 4 independent processes and to let one call another.
But this was something that I couldn´t do in activiti designer

Why couldn't you do this with the Activiti Designer?
You can use a call activity, right?

Best regards,

Forgive me, for I am a noob

Is "call activity" the element that lets me call another process?

If so, how do I specify the process to call?
if would have expected a field to select one of the activiti files for example, but all i can do is to enter a value into "Calles Element" … what do I have to enter here ?

Maybe you should read the docs a little, and maybe even buy the activiti in action book by tijs rademaker… It's all in there

Ok, here is the answer (for those people who might have as little knowledge as I have):

Add a "Call activity" node and add in Section "Main config" for Called Element the ID of the process you are about to call.
This is case sensitive.
