form rerendering and A4J
Hi All,
I have some a form that contains <a4j:commandButton> tags that reRender the form. After the first reRender, the commandButtons cease to work. I have created a simple page and backing bean that show the problem I'm having.
I'm using Facelets, Seam and EJB3

<head><title>Feedback Test</title></head>
<body>
<h:form id='formSend'>
<s:div id='divFeedback'>
<s:fragment rendered='#{not testAction.initialized and not testAction.sent}'>
<p>Step 1: Hit Initialize</p>
<a4j:commandButton id='cmdInit' action='#{testAction.init}' reRender='divFeedback' value='Initialize'/>
</s:fragment>
<s:fragment rendered='#{testAction.initialized}'>
<p>Step 2: Hit Send</p>
<a4j:commandButton id='cmdSend' action='#{testAction.send}' reRender='divFeedback' value='Send'/>
</s:fragment>
<s:fragment rendered='#{testAction.sent}'>
<p>Step 3: Done</p>
<p>If you can see this, then this page is working correctly.</p>
<a4j:commandButton id='cmdClear' action='#{testAction.clear}' reRender='divFeedback' value='Start Over'/>
</s:fragment>
</s:div>
</h:form>
</body>
</html>
Backing Bean:
package com.mc.test;
import org.jboss.seam.annotations.Name;
import org.jboss.seam.annotations.Logger;
import org.jboss.seam.annotations.Scope;
import org.jboss.seam.log.Log;
import org.jboss.seam.ScopeType;
@Name("testAction")
@Scope(ScopeType.CONVERSATION)
public class TestAction {
@Logger
Log log;
private String state;
public TestAction() { }
public void init() {
log.debug("Do init()");
this.state = "initialized";
}
public void send() {
log.debug("Do send()");
this.state = "sent";
}
public void clear() {
log.debug("Do clear()");
this.state = null;
}
public Boolean getInitialized() { return "initialized".equals(this.state);}
public Boolean getSent() { return "sent".equals(this.state);}
}
Upon clicking the Initialize button, the testAction.init action is invoked, and the form re-renders Step 2, as it should. However, then clicking Send does not invoke the testAction.send action.
I found that if I change the scope of the backing bean to Session, the form re-renders correctly, but that is not an option for our production site.
Any help would be greatly appreciated,
thanks,
Al
