I'm really getting confused because I'm pretty new to this whole topic. I'm currently developing a project using spring webflow. In my webinterface a user has to type in a username that is than stored in a bean.
The Form:
<fieldset>
<legend>User Details</legend>
<h:outputText value="Please enter the Name for your Broker: " />
<h:inputText id="brokerName" value="#{brokerBean.brokerName}"/>
<h:outputText value="Please enter the password for your Broker: " />
<h:inputSecret id="password" value="#{brokerBean.password}"/>
</fieldset>
<p:commandButton value="Register Broker" action="register" ajax="false"/>
The according bean:
public class HumanBrokerBean implements Serializable{
/** The Constant serialVersionUID. */
private static final long serialVersionUID = 1L;
/** The broker name. */
private String brokerName;
/** The password. */
private String password;
private double cashPosition = 0;
... getters & setters...
After typing in the username the user is forwarded to the next page where his current cashPosition should be displayed and updated every 5 seconds, because the value might have changed (managed that with PrimeFaces poll). This is working so far.
When the user has typed in his username and some other values he presses a button and a transition of the according flow is fired.
<view-state id="view">
<transition on="register" to="mainpage">
<evaluate expression="brokerBean.checkCredentials(flowRequestContext)" />
<evaluate expression="connectionBean.connect(brokerBean.brokerName, brokerBean.password, brokerBean)" />
</transition>
</view-state>
And the method of the ConnectionBean:
public boolean connect(String username, String password, HumanBrokerBean brokerBean){
ConnectionService connection = new ConnectionService();
//if there have been problems while establishing the connection
if(!connection.connect(username, password, this.serverConnection, byPass, brokerBean)){
return false;
}
//if connection was established
return true;
}
To update the values of the bean, I forwarded the bean object to some other class
public class ConnectionService {
public boolean connect (String username, String password, String serverURL,
boolean bypass, HumanBrokerBean brokerBean){ ....
}
}
When i try to outprint the variable-values of the bean object with
System.out.println("Brokername :"+brokerBean.getBrokerName())
I'm getting the correct results. When I now try to update the cashPosition with
brokerBean.setCashPosition();
The correct result is not displayed in my webinterface poll-section. The initial value of zero is returned always.
As mentioned above, I implemented the polling function with primefaces-poll, which uses AJAX.
<h:form>
<h:outputText id="txt_cash" value="#{brokerBean.cashPosition}" />
<p:poll interval="3" update="txt_cash" />
</h:form>
And the AJAX response I always get... returns always 0.0, which is the initial value of the cashPosition of each Broker...
<?xml version='1.0' encoding='UTF-8'?>
<partial-response><changes><update id="j_idt16:txt_cash"><![CDATA[<span id="j_idt16:txt_cash">0.0</span>]]></update><update id="javax.faces.ViewState"><![CDATA[e1s2]]></update></changes><extension primefacesCallbackParam="validationFailed">{"validationFailed":false}</extension></partial-response>
For me that means, that there are two different instances of my BrokerBean but I'm not sure why. I think I will have to use some annotation in my bean, but I'm not sure which one.
What would I need to do to make this scenario run?
