Sometimes on server log, FullAjaxExceptionHandler produce this log :
FullAjaxExceptionHandler: An exception occurred during rendering JSF ajax response. Error page '/errorpages/500.xhtml' CANNOT be shown as response is already committed. Consider increasing 'javax.faces.FACELETS_BUFFER_SIZE' if it really needs to be handled.
javax.faces.FacesException: Cannot find component for subexpression "bodies" from component with id "invoiceEditorFormPaPr12:tabViewMain" in full expression "@form:tabViewMain:bodies" referenced from "invoiceEditorFormPaPr12:tabViewMain:j_idt1751".
Obviusly this my develop error, but if not show error page is difficult to find. I increased buffer size, log disappear but error page not show.
What wrong for show error page?
In other ajax errors, error page is shown correctly
