Taskflow return listener
In called taskflow you can have backing bean which does some operation and say it puts some value in pageflowscope in the child taskflow using below code
HashMap map = new HashMap();
map.put("userId", userRow.getAttribute("ApplUserId"));
map.put("userName", fullName);
AdfFacesContext.getCurrentInstance().getPageFlowScope().put("userDetail", map);
Define a simple return activity in child taskflow, nothing special here
Now in parent taskflow’s jspx/jsff page button/event which calls child taskflow add a returnlistener
The method code looks like
public void onTaskFlowReturn(ReturnEvent returnEvent) {
bhcLogger.entering("UserRoleMaintain.class", "onTaskFlowReturn");
HashMap userDetail = (HashMap)returnEvent.getReturnParameters().get("userDetail");
}
Where in the child’s taskflow attributes are captured in returnEvent object.
