How to add activiti elements 2 bpmn.xml generated by modeler

radhe_rajput

Hi,
I am looking for the way to create activiti specific bpmn2.0.xml using activiti-modeler only. I am able to customize the attributes of the task as per activiti to the activiti-modeler, I have achieved it by modifing properties of stencils of activiti2.0.json file. But when modeler generates the BPMN.xml, it do not include activiti specific extension elements. Is there any way to achieve this.

Thanks in advance.

Hi,

Did you look at the BPMN 2.0 generator logic in the Activiti Modeler?
The best place to ask this is in the Signavio core components project.

Hello,
Finally I am able to do it, Somebody who have such requirement can following way.
Step 1.Modify the <MODELER-WEB-APP>\editor\stencilsets\extensions\bpmn2.0activiti\bpmn2.0activiti.json json file and add/remove activiti specific attributes.

This step make your attributes get visible on attributes pallete and start getting reflected to your-process.signavio.xml file.

Now to make your attributes getting reflected to your-process.bpmn20.xml. Following steps need to be performed.

Step 2.Modify the source code of the corresponding FactoryClass and invoke explicitly setter methods of such attributes you have added.
e.g. For executing any service task in activiti you want excute java type task which needs class name for execution.
for added new class variable to de.hpi.bpmn2_0.model.activity.type.ServiceTask class and explicitly invoke service task into
de.hpi.bpmn2_0.factory.node.TaskFactory class.
ServiceTask task = new ServiceTask();
task.setId(shape.getResourceId());
task.setName(shape.getProperty("name"));
task.setClass(…)…;

Hoping this small explanation may help somebody.

Thanks,
Radhe

Hi,

I'm trying to do the same, I added a new attribute in the pallete. Now I want to have it in my bpmn.xml file.

I have now a new field called "Formular" with the id "form". I only want it for the userTask type.

I modified the UserTask class

and the TaskFactory class

@Property(name = "tasktype", value = "User")<br> public UserTask createUserTask(GenericShape shape) {<br>&nbsp; UserTask task = new UserTask();<br><br>&nbsp; task.setId(shape.getResourceId());<br>&nbsp; task.setName(shape.getProperty("name"));<br><br>&nbsp; /* Set implementation property */<br>&nbsp; String implementation = shape.getProperty("implementation");<br>&nbsp; if (implementation != null) {<br>&nbsp;&nbsp; task.setImplementation(UserTaskImplementation<br>&nbsp;&nbsp;&nbsp;&nbsp; .fromValue(implementation));<br>&nbsp; }<br>&nbsp; <br>&nbsp; /*Set form property*/<br>&nbsp; String form = shape.getProperty("form");<br>&nbsp; if(form != null){<br>&nbsp;&nbsp; task.setForm(form);<br>&nbsp; }<br><br>&nbsp; /* Set ActivityResources */<br>&nbsp; String resourcesProperty = shape.getProperty("resources");<br>&nbsp; if (resourcesProperty != null) {<br>&nbsp;&nbsp; this.setActivityResources(task, resourcesProperty);<br>&nbsp; }<br><br>&nbsp; return task;<br> }<br>

But there is nothing when I look on the output file. Any idea to solve the problem? Thanks
