对于bpmn属性面板的servive任务下的委托条目的更改未在UI上更新

我正在尝试修改“服务任务”类型下“常规”选项卡的“详细信息”部分 .

What I want ?

我试图实现这一点，当用户选择实现类型作为JavaClass我显示委托字段的下拉列表而不是文本框，除了JavaClass之外的任何其他选择它应该是文本框 .

后来我想将动态数据加载到下拉列表中 .

What I tried ?

我尝试了以下两种方法

1：编辑文件camunda\parts\implementation\Delegate.js再取一个存储entryFactory.selectBox的var，并在type == class上返回module.exports中新创建的选择框，否则返回默认文本框 .

module.exports = function(element, bpmnFactory, options) {

  var getImplementationType = options.getImplementationType,
      getBusinessObject     = options.getBusinessObject;

  var delegateEntrySelect = entryFactory.selectBox({
    id: 'delegate',
     label: 'Value',
    selectOptions: [
      {value:"one",name:"one"},{value:"two",name:"two"}
    ],
    modelProperty: 'delegate',
    emptyParameter: false,

    get: function(element, node) {
      var bo = getBusinessObject(element);
      var type = getImplementationType(element);
      var attr = getAttribute(type);
      var label = getDelegationLabel(type);
      return {
        delegate: bo.get(attr),
        delegationLabel: label
      };
    },

    set: function(element, values, node) {
      var bo = getBusinessObject(element);
      var prop = {};
      prop[attr] = values.delegate || '';
      return cmdHelper.updateBusinessObject(element, bo, prop);
    },

    validate: function(element, values, node) {
      return isDelegate(getImplementationType(element)) && !values.delegate ? { delegate: 'Must provide a value' } : {};
    }
  });   

  var delegateEntry = entryFactory.textField({
    id: 'delegate',
    label: 'Value',
    dataValueLabel: 'delegationLabel',
    modelProperty: 'delegate',

    get: function(element, node) {
      var bo = getBusinessObject(element);
      var type = getImplementationType(element);
      var attr = getAttribute(type);
      var label = getDelegationLabel(type);
      return {
        delegate: bo.get(attr),
        delegationLabel: label
      };
    },

    set: function(element, values, node) {
      var bo = getBusinessObject(element);
      var type = getImplementationType(element);
      var attr = getAttribute(type);
      var prop = {};
      prop[attr] = values.delegate || '';
      return cmdHelper.updateBusinessObject(element, bo, prop);
    },

    validate: function(element, values, node) {
      return isDelegate(getImplementationType(element)) && !values.delegate ? { delegate: 'Must provide a value' } : {};
    }
  });

  var eleTOReturn = (getImplementationType(element) && getImplementationType(element) == "class") ? delegateEntrySelect : delegateEntry
  console.log("returning ele",eleTOReturn)
  return [ eleTOReturn ];
};

我得到的输出是：

2：传递了selectBox和默认文本框但是通过条件区分它们，例如：selectBox（！isDelegate（getImplementationType（element））||（isDelegate（getImplementationType（element））&& type！==“class”））

b：textBox（！isDelegate（getImplementationType（element））||（isDelegate（getImplementationType（element））&& type ===“class”））

在这两种情况下，JS代码执行良好，并且在camunda\parts\serviceTaskDelegateProps.js第60行内的group.entries变量下可以看到相同但它们不会在UI上反映出来 .

Delegate.js代码如下

module.exports = function(element, bpmnFactory, options) {

var getImplementationType = options.getImplementationType,
  getBusinessObject     = options.getBusinessObject;

var delegateEntrySelect = entryFactory.selectBox({
id: 'delegate',
 label: 'Value',
selectOptions: [
  {value:"one",name:"one"},{value:"two",name:"two"}
],
modelProperty: 'delegate',
emptyParameter: false,

get: function(element, node) {
  var bo = getBusinessObject(element);
  var type = getImplementationType(element);
  var attr = getAttribute(type);
  var label = getDelegationLabel(type);
  return {
    delegate: bo.get(attr),
    delegationLabel: label
  };
},

set: function(element, values, node) {
  var bo = getBusinessObject(element);
  var prop = {};
  prop[attr] = values.delegate || '';
  return cmdHelper.updateBusinessObject(element, bo, prop);
},

validate: function(element, values, node) {
  return isDelegate(getImplementationType(element)) && !values.delegate ? { delegate: 'Must provide a value' } : {};
},

disabled: function(element, node) {
  var type = getImplementationType(element);
  console.log("SELECT DISABLE",(!isDelegate(getImplementationType(element)) || (isDelegate(getImplementationType(element)) && type !== "class")))
  return (!isDelegate(getImplementationType(element)) || (isDelegate(getImplementationType(element)) && type !== "class"));
}
});   

var delegateEntry = entryFactory.textField({
id: 'delegate',
label: 'Value',
dataValueLabel: 'delegationLabel',
modelProperty: 'delegate',

get: function(element, node) {
  var bo = getBusinessObject(element);
  var type = getImplementationType(element);
  var attr = getAttribute(type);
  var label = getDelegationLabel(type);
  return {
    delegate: bo.get(attr),
    delegationLabel: label
  };
},

set: function(element, values, node) {
  var bo = getBusinessObject(element);
  var type = getImplementationType(element);
  var attr = getAttribute(type);
  var prop = {};
  prop[attr] = values.delegate || '';
  return cmdHelper.updateBusinessObject(element, bo, prop);
},

validate: function(element, values, node) {
  return isDelegate(getImplementationType(element)) && !values.delegate ? { delegate: 'Must provide a value' } : {};
},

disabled: function(element, node) {
  var type = getImplementationType(element);
  console.log("TEXT DISABLE",(!isDelegate(getImplementationType(element)) || (isDelegate(getImplementationType(element)) && type === "class")))
  return (!isDelegate(getImplementationType(element)) || (isDelegate(getImplementationType(element)) && type === "class")); 
}  
});

 return [ delegateEntrySelect, delegateEntry ];
};

我得到的输出是

有人可以帮帮我吗

谢谢
