Modeler Source Code

qbeukes

Hi,

Is the Activiti Modeler open source as well? I understand it's built on the open source component of Signavio's modeler, but having looked around I can't seem to find it's source code.

There is much improvements needed to make it more practical.

thanks,

Yes, the Modeler is MIT licences.

You can find the source code here: http://code.google.com/p/signavio-core-components/

That one is for the activiti modeler or signavio?
what about this link http://docs.codehaus.org/display/ACT/Developers+Guide#DevelopersGuide-Buildingthedistribution ?

Hi,

It's the same. The Signavio Modeler is the Activiti Modeler.
The link you refer to is for the other Activiti components.

Best regards,

Thanks
but, can i download everything from here http://svn.codehaus.org/activiti/projects/designer/trunk/ ?
after that how do i have to proceed?
Is this the release 5.7 (just saw a post with videos and it looks great)?

ronald_van_kuij

that is the designer, not the modeler

elstefen

ok.
so, stupid question: what's the difference?
this is the designer: http://bpmn20inaction.blogspot.com/2011/07/activiti-eclipse-designer-570-release.html
but the modeler is about what? i found this link: http://www.activiti.org/components.html and seems that the modeler is to model BPMN, which is the same as the designer.
or did i miss something?

ronald_van_kuij

Sure, just like pen and paper can be used to draw bpmn, or even charcoal and a rock 😉

Read the first alinea of each chapter in the docs about the modeler and the designer and you know the basic differences. Read more of those chapterd and you will be enlightened.

Thanks.
so the modeler lets to draw a full BPMN2.0 process, but it cannot be executed.
the designer lets only to use the grammar supported by the engine (no pools, no message flow and other things are missed).

Bascially, a process modeled inside the modeler could not be executed by the activiti engine. instead, modeling with designer should place me in a "safe" area for the execution.

am i right?

ronald_van_kuij

Correct. The designer will get even better than it already is during te coming months as will the engine. It might be that they (engine and designer) not go in parallel 100% of the time, so it might be the engine supports something the designer does not, but it wil soon after.
