/*
  因為 picker 是統一的需求, 為了統一控管, 改為 service + schemaApi, 同時也可以大幅縮端程式碼
  目前測試時有一個 issue 尚待處理, 原定義在 picker 內的 label 會因改為 service + schemaApi 而不顯示, 影響排版
  
  這樣的寫法可以執行, 但無法 update picker.name 傳參數會有問題
  {
	"type": "service",
	"schemaApi": "get:/pages/zen_picker_basm601.json"
  },

  以下的寫法測試仍有問題(不會報錯, 但 picker 未顯示)
  {
	"type": "service",
	"schemaApi": {
		"method": "post",
		"url": "http://127.0.0.1:5050/xapi/v2/zenWizard/zen_get_picker/3/",
		"data": {
			"para01": "basm61",
			"para02": "para05",
			"para03": "lg"
		},
		"dataType": "form"
	}
  },
						
  CALL zen_get_picker('basm601', 'para05');
