    text
    copied!<p>I've a <code>&lt;p:selectOneMenu&gt;</code> with <code>String</code> entries and a <code>valueChangeListener</code> on it.</p> <p>View:</p> <pre><code>&lt;p:selectOneMenu value="#{myLdapEntry.oneMenuselectedValue}" effect="fade" style="font-size:12px;" valueChangeListener="#{myLdapEntry.menuValueChanged}"&gt; &lt;f:selectItem itemLabel="" itemValue=""/&gt; &lt;f:selectItems value="#{treeBean.objclasslist}" var="objclass" itemLabel="#{objclass}" itemValue="#{objclass}" /&gt; &lt;p:column&gt; #{o} #{objclass} &lt;/p:column&gt; &lt;f:ajax event="change" render=":form:objclassAttrsValstab" /&gt; &lt;/p:selectOneMenu&gt; </code></pre> <p>Model:</p> <pre><code>List&lt;String&gt; objectClassList = new ArrayList&lt;String&gt;(); public void menuValueChanged(ValueChangeEvent vce) { String newValue = vce.getNewValue().toString(); objectClassList.add(newValue); System.out.println(objectClassList); } </code></pre> <p>I would like to remember every previously seledted item in the <code>objectClassList</code>. But the problem is that it always contains only the last selected item and not the items before that. I've even tried with a <code>Vector</code> instead of a <code>List</code>, but still have the same result. </p> <p>I think that the <code>valueChangeListener</code> method creates a new bean instance each time so that the <code>objectClassList</code> is reinitialized each time. </p> <p>Is this true? How is this caused and how can I solve it?</p>
