We changed the template of the page, and afterwards the calendar popup started to appear away from the button.
The component configuration is: <t:inputCalendar value="#{ConsultaDiarioForm.dataInicio}" renderPopupButtonAsImage="true" renderAsPopup="true" popupWeekString="Semana" size="10" popupTodayString="Hoje é" id="dataInicio" popupDateFormat="dd/MM/yyyy" alt="Digite a data inicial para pesquisar" title="Digite a data inicial para pesquisar"> </t:inputCalendar> The imagens of the before/After Before: https://picasaweb.google.com/lh/photo/H9ML-JtAIzj-5mXeunEM7SyftixIMAaR_uGG46TnU-0?feat=directlink After: https://picasaweb.google.com/lh/photo/-S1izZxddwHVR0EVg362TiyftixIMAaR_uGG46TnU-0?feat=directlink I would like to highlight that when using firebug, it shows in the div tag that wraps the calendar a fixed posiition by top and left style attributes. We dont know however where this is set. Any ideas?
