<h:panelGrid id="panelMyButton">
      <a4j:commandButton value="myButton" action="#{myBean.execute()}" reRender="panelMyButton" ajaxSingle="true" />
</h:panelGrid>
...

@Name("myBean")
@Scope(ScopeType.SESSION)
@Synchronized(timeout=99999999)
public class EditReclamationAction implements Serializable{   
    ...
    public void init(){
       ...
    }
    public void execute(){

    }
    ...
}

<page view-id="myView.xhtml">
    ...
    <action execute="#{myBean.init()}" />
</page>

Problem

Even if the action in <a4j:commandButton> is in ajax, the tag in pages.xml run the function init(). That’s how work in Seam.

Solution

Change the way to execute function and the scope type of the bean.

• In the bean, modify @Scope(ScopeType.SESSION) by @Scope(ScopeType.PAGE) to let possibility to initialize for each page loading
• In the bean, add “@Create” upper init(), that means for Seam run this function for each page loading
• Delete the tag <action> in pages.xml

like this :

 
...
<h:panelGrid id="panelMyButton">
      <a4j:commandButton value="myButton" action="#{myBean.execute()}" reRender="panelMyButton" ajaxSingle="true" />
</h:panelGrid>
...

@Name("myBean")
@Scope(ScopeType.PAGE)
@Synchronized(timeout=99999999)
public class EditReclamationAction implements Serializable{   
    ...
    @Create
    public void init(){
       ...
    }
    public void execute(){

    }
    ...
}

<page view-id="myView.xhtml">
    ...

</page>
