问题
I'm facing a strange problem here. In my page i have two outputPanel. Inside the first, there is a schedule exhibiting my events queried from the database. Inside the other one, there is a datatable exhibiting the same events just as another means of visualization. Furthermore, there is a selectOneRadio that alternates between the two outputPanels. The problem is: When the page loads, the default outputPanel (the one containing the schedule) (SCREEN 1) is loaded perfectly. But when i alternate the selectOneRadio to the outputPanel containing the datatable and then turn back (SCREEN 2), the outputPanel doesn't load. And the console of the browser shows the following message when i click anywhere on the page:
Uncaught TypeError: Cannot read property 'top' of undefined primefaces.js.xhtml:1
Uncaught TypeError: Cannot read property 'left' of undefined primefaces.js.xhtml:16
Here is the xhtml page:

// Realizando a lógica de painéis

exibirComoTabela = !exibirComoCalendario;
if (eventos == null) {
try {
// Consultar os eventos para exibir no DataTable

} catch (Exception e) {
}
}
}
}
public void onEventSelect(ScheduleEntrySelectEvent entrySelectEvent) {
try {

} catch (Exception e) {

}
public void onDataInicioAlterada(DateSelectEvent e) {
}
public void onDataTerminoAlterada(DateSelectEvent e) {
}
public void onDataSelecionada(DateSelectEvent e) {

} catch (Exception e) {

}

Try to replace <p:selectOneRadio & p:ajax with <h:selectOneRadio & f:ajax
I'm not a maven user , do double check that you really using only 3.4.2 and take a look at this thread... [PF 3.1 Snapshot] Dialog + OverlayPanel + SelectOneMenu JS E
