Action bean not being called - ajax

Question

I have problem using JSF 2.0. The command button doesn't call the bean, I have already read the balusc answer commandButton/commandLink/ajax action/listener method not invoked or input value not updated but I don't think I'm encountering those cases,
this is the code I'm using:
<ui:composition xmlns="http://www.w3.org/1999/xhtml"
xmlns:ui="http://java.sun.com/jsf/facelets"
xmlns:f="http://java.sun.com/jsf/core"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:p="http://primefaces.org/ui"
xmlns:c="http://java.sun.com/jstl/core">
....
<ui:repeat var="skill" value="#{skillsView.skills}">
<h:form>
<h:commandButton value="#{skill}"
action="#{skillsController.removeSkillFromPublication}" ajax="true">
<f:param name="theskill" value="#{skill}" />
</h:commandButton>
</h:form>
</ui:repeat>
</ui:composition>
UPDATE 1 :
this my controller
#Controller
#Scope(value = WebApplicationContext.SCOPE_REQUEST)
public class SkillsController extends BController {
private static final Logger logger = LoggerFactory
.getLogger(SkillsController.class);
public void removeSkillFromPublication() {
logger.info("Deleting : " + getParameter("theskill"));
publicationService.removeSkillFromPublication(publicationDetailView
.getPublicationFullView().getId(), getParameter("theskill"));
skillsView.setSkills(publicationService
.getSkillsFromPublication(publicationDetailView
.getPublicationFullView().getId()));
}
}
i don't get the the logger neither the task is executed , i already tested with actionlistner with controller with actionevent and this doesent work
UPDATE 2 :
It's working with changing the SCOPE of the skillsView To WebApplicationContext.SCOPE_SESSION , anybody know why ?!!
#Controller
#Scope(value = WebApplicationContext.SCOPE_SESSION)
public class SkillsView {
List<String> skills;
private String currentSkill;
public List<String> getSkills() {
return skills;
}
public void setSkills(List<String> skills) {
this.skills = skills;
}
public String getCurrentSkill() {
return currentSkill;
}
public void setCurrentSkill(String currentSkill) {
this.currentSkill = currentSkill;
}

The h:commandButton attribute action requires you to return a String
Taken from the jsf-toolbox:
action
The action attribute accepts a method-binding expression for a backing bean action method to invoke when this component is activated by the user. An action method must be a public method with no parameters that returns a String. The returned string represents the logical outcome of the action (eg. "success", "failure", etc. ) and is used by the JavaServer Faces MVC framework to determine which view to display next.
[bolding by me]
Instead use the actionListener property:
<h:commandButton actionListener="${skillsController.removeSkillFromPublication()}" ajax="true">
<f:param name="theskill" value="#{skill}" />
</h:commandButton>
Keep in mind you will have to change the method-signature to have an ActionEvent as parameter:
public void removeSkillFromPublication(ActionEvent e) {
//...
See the toolbox:
actionListener
The actionListener attribute accepts a method-binding expression for a backing bean action listener method that will be notified when this component is activated by the user. An action listener method must be a public method with an ActionEvent parameter and a void return type.
Alternatively you could have your removeSkillFromPublication() return a String. But that seems to be the wrong approach here.
