[jbossseam-issues] [JBoss JIRA] Commented: (JBSEAM-1753) Problems mixing a4j:support, @In and component binding
5:25 p.m.
[ http://jira.jboss.com/jira/browse/JBSEAM-1753?page=comments#action_12370790 ]
Alexander Smirnov commented on JBSEAM-1753:
-------------------------------------------
Possible workaround :
- restore conversation-scope beans before RESTORE_VIEW phase, in the custom JSF
StateManager. Ajax4Jsf have own StateManager, with a hook for save/restore any custom
objects in addition to the view state.
Problems mixing a4j:support, @In and component binding
------------------------------------------------------
Key: JBSEAM-1753
URL: http://jira.jboss.com/jira/browse/JBSEAM-1753
Project: JBoss Seam
Issue Type: Bug
Affects Versions: 2.0.0.BETA1
Environment: ajax4jsf 1.1.1, JBoss Seam 1.2.1, Facelets 1.1.11, MyFaces 1.1.6
nightly from 20070614, Tomcat 5.5.23
Reporter: Daniel Wiell
Assigned To: Alexander Smirnov
Here is a simple example that shows how to reproduce this:
<?xml version='1.0' encoding='UTF-8'?>
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:f="http://java.sun.com/jsf/core"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:a4j="https://ajax4jsf.dev.java.net/ajax">
<head><title>Seam + ajax4jsf + binding</title></head>
<body>
<h:form>
Input:
<h:inputText binding="#{testController.input}"
value="#{testController.value}">
<a4j:support event="onkeyup" reRender="repeater"/>
</h:inputText>
<br/>
Repeat:
<h:outputText id="repeater"
value="#{testController.value}"/>
</h:form>
</body>
</html>
import org.jboss.seam.annotations.In;
import org.jboss.seam.annotations.Name;
import org.jboss.seam.core.FacesMessages;
import javax.faces.component.UIInput;
@Name("testController")
public class TestController {
@In
FacesMessages facesMessages;
private UIInput input;
private String value;
public UIInput getInput() { return input; }
public void setInput(UIInput input) { this.input = input; }
public String getValue() { return value; }
public void setValue(String value) { this.value = value; }
}
When entering something in the inputField, the following is thrown:

Everything works fine if: the @In annotation is removed or the component binding is
removed
