    copied!<p><strong>Completely edited:</strong> Maybe I was mixing problems and misinterpreted. After simplifying my code the question simplifies to: How can I prevent the <code>&lt;p:commandButton&gt;</code> from executing it's action method on page refresh (like when you hit F5 inside browser window)?</p> <p>JSF Code: </p> <pre><code> &lt;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"&gt; &lt;h:body&gt; &lt;h:form&gt; &lt;h:outputText value="#{bugBean.number}" /&gt; &lt;h:outputText value="#{bugBean.isComplete()}" /&gt; &lt;p:commandButton id="entryCommand" value="add" action="#{bugBean.increase()}" update="@form" oncomplete="#{bugBean.complete()}"/&gt; &lt;/h:form&gt; &lt;/h:body&gt; &lt;/html&gt; </code></pre> <p>backing bean code: </p> <pre><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; } } </code></pre> <p><strong>Update:</strong> Even if I remove the <code>oncomplete</code> stuff like this an click the <code>&lt;p:commandButton&gt;</code> just once, the counter goes up on every page refresh.</p> <pre><code>&lt;h:form&gt; &lt;h:outputText value="#{bugBean.number}" /&gt; &lt;p:commandButton id="entryCommand" value="add" action="#{bugBean.increase()}" update="@form"/&gt; &lt;/h:form&gt; </code></pre>
