flowable-cmmn-moddle

Flowable moddle extensions for CMMN 1.1. This package provides Flowable-specific extensions for cmmn-moddle, enabling support for Flowable's custom CMMN elements and attributes in cmmn-js based applications.

Installation

npm install flowable-cmmn-moddle

Usage

With cmmn-js

import CmmnModeler from 'cmmn-js/lib/Modeler';
import flowableDescriptor from 'flowable-cmmn-moddle/resources/flowable';

const modeler = new CmmnModeler({
  container: '#canvas',
  moddleExtensions: {
    flowable: flowableDescriptor
  }
});

With cmmn-js Properties Panel

import CmmnModeler from 'cmmn-js/lib/Modeler';
import propertiesPanelModule from 'cmmn-js-properties-panel-flowable';
import propertiesProviderModule from 'cmmn-js-properties-panel-flowable/lib/provider/flowable';
import flowableDescriptor from 'flowable-cmmn-moddle/resources/flowable';

const modeler = new CmmnModeler({
  container: '#canvas',
  propertiesPanel: {
    parent: '#properties-panel'
  },
  additionalModules: [
    propertiesPanelModule,
    propertiesProviderModule
  ],
  moddleExtensions: {
    flowable: flowableDescriptor
  }
});

Example CMMN XML with Flowable extensions:

<?xml version="1.0" encoding="UTF-8"?>
<definitions xmlns="http://www.omg.org/spec/CMMN/20151109/MODEL"
             xmlns:flowable="http://flowable.org/cmmn"
             targetNamespace="http://flowable.org/cmmn">
  <case id="myCase" flowable:initiatorVariableName="initiator">
    <casePlanModel id="casePlanModel" flowable:formKey="startForm">
      <planItem id="humanTaskPlan" definitionRef="humanTask"/>
      <humanTask id="humanTask" 
                 flowable:assignee="${initiator}"
                 flowable:candidateGroups="managers"
                 flowable:formKey="taskForm"/>
    </casePlanModel>
