本实验在《Task Flow使用指南之三:以Dialog方式显示Task Flow》基础之上,获取Task Flow返回值。
1. 选中TaskFlow Call Activity,设置Return参数
2. 双击TaskFlow Call Activity,打开TaskFlow定义,在空白点击一下,设置Return参数
3. 修改departmentList页面中调用TaskFlow的按钮代码,增加returnListener
(1)页面代码
<af:commandButton text="To Employees" id="cb1" action="toEmployees" useWindow="true"
windowEmbedStyle="inlineDocument" windowWidth="600" windowHeight="320"
returnListener="#{myBackingBean.employeesTaskFlow2ReturnListener}">
<af:setPropertyListener from="#{bindings.DepartmentId}" to="#{pageFlowScope.deptId}" type="action"/>
</af:commandButton>
(2)Managed Bean代码
public void employeesTaskFlow2ReturnListener(ReturnEvent returnEvent) {
System.out.println("$$$$$$$$$$$$$$$$$ return Value: " + returnEvent.getReturnValue());
Map
4. 修改employeeList页面中返回按钮的代码,增加setPropertyListener
<af:commandButton text="to Return" id="cb1" action="toReturn">
<af:setPropertyListener from="#{bindings.EmployeeId.inputValue}" to="#{pageFlowScope.empId}" type="action"/>
</af:commandButton>
5. 运行
Console日志中会输出:
$$$$$$$$$$$$$$$$$ return Value: null
$$$$$$$$$$$$$$$$$ return Values: empId : 136
