Primefaces tabview: set the active index on tab change
- by Virgi
I've got a tab view that contains two tab.
When I switch from tab 1 to tab 2, I'm calling some code that executes a validation and updates some values. Depending on the result of this validation, I would like to stay on tab 1, or go to tab 2, and refresh the tabs' content.
My tabview:
<h:form id="form">
<p:tabView id="tabview" activeIndex="#{ctrl.idx}" dynamic="true" cache="false">
<p:ajax event="tabChange" listener="#{ctrl.doStuff}" update=":form:tabview"/>
<p:tab title="Tab 1" id="t1">
<h:panelGrid columns="1" cellpadding="10">
<h:outputText value="#{ctrl.s1}"/>
</h:panelGrid>
</p:tab>
<p:tab title="Tab 2" id="t2">
<h:panelGrid columns="1" cellpadding="10">
<h:outputText value="#{ctrl.s2}"/>
</h:panelGrid>
</p:tab>
</p:tabView>
</h:form>
My test code that simly changes the values:
public void doStuff() {
s1 = String.valueOf(Math.random());
s2 = String.valueOf(Math.random());
}
I thought that changing the active tab index in my method would be enough, like that:
public void doStuff() {
// ...
idx = 0;
}
On tabChange event, the method is called but the tabview components goes to the clicked tab, ignoring the idx new value.
I thought adding an update attribute to p:ajax would render the whole tabview but only the tabs and/or the tabs' content is re rendered.
And weirdest of all, if I change update=":form:tabview" to update=":form" or update="@form", I only receive the tab's content in the ajax response - the component disappears from the page!
My bean is viewscoped, I'm using Primefaces 3.5, JSF 2.1 and Tomcat 7.
Any idea? Thanks.
