  1. POSpring Flow: Pass object back and forth from between Main WebFlow and Subflow
    text
    copied!<p>I am calling a subflow from a main flow. I have been able to pass an object <code>ShareHolderProfile</code> to the SubFlow from the MainFlow. However, I am not sure if this same object is not being passed back to the MainFlow or I am not properly accessing it in my JSP. Here is how I am doing it. </p> <h1>MainFlow.xml</h1> <pre><code>&lt;?xml version="1.0" encoding="UTF-8"?&gt; &lt;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" start-state="retriveAccount"&gt; &lt;var name="acctProfile" class="com.abc.xyz.account.ShareHolderProfile"/&gt; &lt;view-state id="retriveAccount" view="AccountView"&gt; &lt;transition on="Success" to="createAccountSubFlow"/&gt; &lt;/view-state&gt; &lt;subflow-state id="createAccountSubFlow" subflow="createAccountSubFlow"&gt; &lt;input name="acctProfile" value="acctProfile"/&gt; &lt;transition on="finish" to="showAlternateRoute"/&gt; &lt;/subflow-state&gt; &lt;view-state id="showAlternateRoute" view="showAlternateView" model="acctProfile"&gt; &lt;on-entry&gt; &lt;evaluate someExpression result="viewScope.SomeValue"/&gt; &lt;/on-entry&gt; &lt;transition on="viewAction" to="accountDetails"/&gt; &lt;/view-state&gt; </code></pre> <h1>SubFlow.xml</h1> <pre><code>&lt;?xml version="1.0" encoding="UTF-8"?&gt; &lt;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" start-state="showAccount"&gt; &lt;input name="acctProfile" /&gt; &lt;view-state id="showAccount" view="randomView" model="acctProfile"&gt; &lt;on-entry&gt; &lt;evaluate expression="SomExpression"/&gt; &lt;/on-entry&gt; &lt;transition on="SomeEvent" to="NextState"/&gt; &lt;/view-state&gt; &lt;view-state id="NextState" view="SomeRandomView" model="acctProfile"&gt; &lt;on-entry&gt; &lt;evaluate expression="controller.Method(acctProfile)" result="viewScope.profileForm"/&gt; &lt;/on-entry&gt; &lt;transition on="viewResult" to="finish"/&gt; &lt;/view-state&gt; &lt;end-state id="finish" /&gt; </code></pre> <p>Now, for the most part, the flows in the applications works fine. However, the problem is that I have been trying to access some attributes (Member variable) from acctProfile in one of my jsp . Something like - acctProfile.FirstName</p> <p>However, I am not able to do this. Is the acctProfile object not being passes from the subFlow to Mainflow or am I using it incorrectly in the JSP. Please advise. </p> <p>Thanks in advance</p>
