DIRECT 新技术 Extjs扩展实现资本币制上拉存取值 Ext.ux.BaseDataComboBox

// 修改 值 对象文件 添加别名字段  currCodeAlias  
private String currCodeAlias  ;
//有XML配置需要的 修改对应的XML  添加属性 currCodeAlias  其值由SQL获取 根据的是
currCode的值  如下所示：
         <property name="currCodeAlias"
			formula="(select '(' || cc.CURR_CODE || ')' || cc.CURR_NAME from EPLATFORM.T_CURR_CODE cc where cc.CURR_CODE = CURR_CODE  )"
			type="string">
        </property>
//保存的时候 

onSave : function(){
   //企业信息 资本币制
		var  currCodeAlias =   this.mainForm.getForm().findField("currCodeAlias").getValue();
		var currCode = currCodeAlias.substring(1,4);
		this.mainForm.getForm().findField('currCode').setValue(currCode);
}

//后台代码--- 通过资本币制序号 查找 设显示名给资本币制别人 以显示到列表框
