Completely edited:
Maybe I was mixing problems and misinterpreted. After simplifying my code the question simplifies to: How can I prevent the <p:commandButton> from executing it's action method on page refresh (like when you hit F5 inside browser window)?
JSF Code:
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:f="http://java.sun.com/jsf/core"
xmlns:ui="http://java.sun.com/jsf/facelets"
xmlns:p="http://primefaces.org/ui">
<h:body>
<h:form>
<h:outputText value="#{bugBean.number}" />
<h:outputText value="#{bugBean.isComplete()}" />
<p:commandButton id="entryCommand" value="add"
action="#{bugBean.increase()}" update="@form" oncomplete="#{bugBean.complete()}"/>
</h:form>
</h:body>
</html>
backing bean code:
package huhu.main.managebean;
import java.io.Serializable;
import javax.enterprise.context.SessionScoped;
import javax.inject.Named;
@Named
@SessionScoped
public class BugBean implements Serializable {
private static final long serialVersionUID = 1L;
private int number;
private boolean isComplete = false;
public void increase(){
number++;
}
public void complete(){
isComplete = true;
}
public int getNumber() {
return number;
}
public void setNumber(int number) {
this.number = number;
}
public boolean isComplete() {
return isComplete;
}
public void setComplete(boolean isComplete) {
this.isComplete = isComplete;
}
}
Update:
Even if I remove the oncomplete stuff like this an click the <p:commandButton> just once, the counter goes up on every page refresh.
<h:form>
<h:outputText value="#{bugBean.number}" />
<p:commandButton id="entryCommand" value="add"
action="#{bugBean.increase()}" update="@form"/>
</h:form>
