Problem when load bpmn file with custom moddle extension


#1

Hi all.
I’ve a custom moddle extension like this:

bpmnModeler = new BpmnJS({
                container: '#canvas',
                keyboard: {
                    bindTo: window
                },
                moddleExtensions: {
                    ab: {
                        'name': 'Sample moddle extensions',
                        'uri': 'http://abansoft.ir/bpmn/ab',
                        'prefix': 'ab',
                        'xml': {
                            'tagAlias': 'lowerCase'
                        },
                        'types': [
                            {
                                'name': 'Variable',
                                'extends': [
                                    'bpmn:Task',
                                    'bpmn:UserTask',
                                    'bpmn:ServiceTask'
                                ],
                                'properties': [
                                    {
                                        'name': 'VarItem',
                                        'isAttr': false,
                                        'type': 'VariableItem'
                                    }
                                ]
                            },
                            {
                                'name': 'VariableItem',
                                'extends': [],
                                'properties': [
                                    {
                                        'name': 'VarName',
                                        'isAttr': true,
                                        'type': 'String'
                                    }
                                ]
                            }
                        ]
                    }
                }
            });

and also I’ve a saved bpmn file like this:
