Customizing the Activiti Modeler

Hi all,I'm trying to customize the Activiti modeler by inserting some custom properties in the nodes. For example, I'm trying to add the activiti:class property to a ServiceTask.I've successuflly added the property in the bpmn2.0.json file and now it's displayed in the palette, however the property

No idea ?
Do you have any clue where could I find some help ?(unfortunately I could not find any oryx designer forum). We are interested to try Activiti but we would need to produce a demo for a customer of us with at least a minimal customization of the editor…….

There are only a few people who have worked with the Modeler codebase. The issue you want to solve is something we currently are also looking into, but not yet found an adequate solution. So any input on your findings could help us bring exactly thing like the 'activiti:class' in the Modeler, in a next release!

I have an idea. Use Json representation stored in singnavio.xml

I change manually for experiment file editor/stencilsets/bpmn2.0/bpmn2.0.json on deployed modeler, so no patch file provided yet. Search this lines

So, new properties stored in <json-representation> in file .signavio.xml
Then build jar from attached sources (depends on activiti-cycle.jar and signavio-core-components.jar).

I want to extend method mentioned before, because activiti-cycle and using his "developer friendly xml" are really pain…

Re: Customizing the Activiti Modeler

al_lv — Fri, 29 Apr 2011 11:24:53 GMT

So, new properties stored in <json-representation> in file .signavio.xml

Where is this file .signavio.xml? I cann't find it.

I also work on the customising of Activit-Modeller.
Do you have maybe more exaples like this? It is very helpfull!
I would appreciate any advice.

Thanks

Best regards

Alexej

Re: Customizing the Activiti Modeler

dryabkov — Fri, 29 Apr 2011 17:10:13 GMT

Where is this file .signavio.xml? I cann't find it.

Modeler saves diagram into two files, <Diagram title>.bpmn20.xml and <Diagram title>.signavio.xml

I'll publish soon my experiment on github, about 2-3 days.

Current problem:

My changes in editor /data/stencilsets/extensions/bpmn2.0activiti/bpmn2.0activiti.json are invisible. If I place the same in editor/data/stencilsets/bpmn2.0/bpmn2.0.json they work.

Re: Customizing the Activiti Modeler

al_lv — Mon, 30 May 2011 12:43:56 GMT

@ dryabkov:
great work!

I am abel now to add new properties to tasks. But after convert there are elements that activiti cannt read:

ns6:type=
<ns8:serviceTask
<ns8:extensionElements>

Do you know how can I define an activiti namespace or delete this "ns8:" by serviceTask and extensionElements?

Thanks a lot!

Alexej

Re: Customizing the Activiti Modeler

dryabkov — Mon, 30 May 2011 20:33:19 GMT

My files contain "ns8:", "ns6:" etc but with correct "xmlns:ns8=…" at parent or grandparents. I use ant to deploy them successfully.
May be classes used for serialization should force namespace with @XmlRootElement(name="formProperty",namespace="http://activiti.org/bpmn")

See http://dryabkov.github.com/activiti-modeler-experiment/

Start point is /activiti/build.xml:

run >ant war tomcat-start
open http://localhost:8080/signaviocore/
save diagram
stop tomcat with ctrl+c
run >ant package convert
see target/models

PS: It does not work in google chrome

Re: Customizing the Activiti Modeler

al_lv — Fri, 03 Jun 2011 12:10:20 GMT

Thanks.

I tried it.
It stopts by downloading of tomcat.
This is the error:
BUILD FAILED
D:\WorkflowEngine\Modeller\dryabkov-activiti-modeler-experiment-b1ff890\activiti
\build.xml:61: org.codehaus.cargo.container.ContainerException: Failed to downlo

The URL is not reachable via Browser also.

How can I fix it? May be simply define a tomcat path in build.xml?

Re: Customizing the Activiti Modeler

dryabkov — Fri, 03 Jun 2011 16:56:33 GMT

This url is stated in /activiti/build.xml. Choose appropriate one from http://tomcat.apache.org/download-60.cgi
It's possible to try download distribution package manually to ${java.io.tmpdir}/cargo/installs.

nice.
It work perfectly now.
thank you.

I can now deploy a converted model from target/models, but it doesn't recognize it as a process.
So that it doesn't eappear in probe/processes.

Have you a same problem?

Hello dryabkov,

I'm trying to deploy activiti-modeler (original 5.6 distribution, not experimental) war file in Liferay CMS. When deploying the app I get the same Path error ( java.lang.IllegalStateException: Path does not point to a directory). How did you get off with this problem?

Thank you so much in advance.

Bye,
Giuseppe.

Re: Customizing the Activiti Modeler

giusdiluca — Thu, 23 Jun 2011 14:23:42 GMT

Hi,

I've fixed all my previous problems. I'm customizing Actviti Modeler to have the properties I need for each shape. Analyzing the bpmn2.0 json file, I noted that there are many different types for each object (stencil) property (i.e. "text", "choice", "string", "complex", "boolean", "color", "integer", "DiagramLink"). So now I would like to define a type "table" to have a so called, let me use the term, "table editor" (we already have in Activiti-Signavio a Text Editor and a Complex Type Editor). Is this implementation possible? It is not important, to me, to mantain the compatibility with BPMN2.0 standard. I just want to have a customized workflow designer web editor.

Thanks to all in advance.

Probe is of no special interest to me. Only engine and modeler are suitable for me. I can't test this case.
