PanelTabbedPane and Backing Bean issue

Question

I have a page with 2 components: a "save" button and a tabbedPane with serverSideTabSwitch set to "true".
The tabbedpane contains 2 tabs and in each tab there is an inputfield whose value is linked to a backing bean.
If the user enters a value in the input field of the first tab, then clicks the second tab, enters a value in the input field of the second tab and then clicks the "save" button, only the value entered in the last chosen tab is set in the backing bean (and thus saved)
Is there a solution for this problem , so that the information in all tabs is set in the backing bean (and also validated) ?
A snippet of my JSP:
<h:form>
<h:commandButton action="#{testtabBean.save}" value="Save" />
</h:form>
<t:panelTabbedPane serverSideTabSwitch="true" >
<t:panelTab id="tab1" label="Tab1">
<h:inputText value="#{testtabBean.text1}"></h:inputText>
</t:panelTab>
<t:panelTab id="tab2" label="Tab2">
<h:inputText value="#{testtabBean.text2}"></h:inputText>
</t:panelTab>
</t:panelTabbedPane>
My backing bean:
public class TestTabBean {
private String text1;
private String text2;
public String getText1() {
return text1;
public void setText1(String text1) {
this.text1 = text1;
public String getText2() {
return text2;
public void setText2(String text2) {
this.text2 = text2;
public String save() {
return null;
}
