[eros]

my problem is... the input name="simulationAnalyzeId" is always null..
please assist me...
thanks

1st flow

<?xml version="1.0" encoding="UTF-8"?>
<flow xmlns="http://www.springframework.org/schema/webflow"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="http://www.springframework.org/schema/webflow
        http://www.springframework.org/schema/webflow/spring-webflow-2.0.xsd">

	<view-state id="enterSimulation" view="view-simulation" model="simulationView" >
		<transition on="rosenka-flow" to="rosenkaSanshutsu" ></transition>		
		<transition on="modoru" to="shuryo" />
	</view-state>
	
	<end-state id="shuryo" view="externalRedirect:/view-menu" />
	
	<end-state id="rosenkaSanshutsu" view="externalRedirect:/simulation/rosenka-flow" />
	
</flow>

2nd flow

<?xml version="1.0" encoding="UTF-8"?>
<flow xmlns="http://www.springframework.org/schema/webflow"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="http://www.springframework.org/schema/webflow
        http://www.springframework.org/schema/webflow/spring-webflow-2.0.xsd">
	
	<input name="simulationAnalyzeId" required="true" />

	<on-start>
		<evaluate expression="simulationService.createRosenkaView(simulationAnalyzeId)"
					result="flowScope.rosenkaView">
		</evaluate>
	</on-start>

	<view-state id="enterRosenka" view="view-rosenka">
		<transition on="modoru" to="shuryo">
		</transition>
	</view-state>

	<end-state id="shuryo" view="externalRedirect:/simulation/simulation-flow" />
</flow>

javascript

<input type = "hidden" value = '${flowExecutionUrl}'  id = "_flowExecutionUrl"  name = "_flowExecutionUrl"></input>

location.href = $("#_flowExecutionUrl").val() + '&_eventId=rosenka-flow&simulationAnalyzeId=' + Id;

[eros]

i found the solution..

<end-state id="rosenkaSanshutsu" view="externalRedirect:/simulation/rosenka-flow?simulationAnalyzeId=${requestParameters.simul ationAnalyzeId}">
</end-state>
