Problem with ajax request in Internet Explorer 11 ------------------------------------------------- Key: RF-13602 URL: https://issues.jboss.org/browse/RF-13602 Project: RichFaces Issue Type: Feature Request Security Level: Public(Everyone can see) Components: base functionality Affects Versions: 4.0.0.Final Environment: Windows 2008, JBoss AS 7.x Reporter: Walter Maidub Assignee: Juraj Húska Labels: ie11, waiting_on_user I have a form with a FileUploader component (disabled) and a rich: select and this one is populated with 3 options, when one of them is selected in the managed bean a boolean variable is set to "true" and the FileUploader panel is updated to enable it. {code} <rich:select id="tipoArchivo" value="#{Bean.tipoArchivo}" required="true" listWidth="320px" styleClass="rf-select-large-width"> <f:selectItems value="#{Bean.Catalogo}" /> <a4j:ajax event="selectitem" execute="@this" render="upload,seccionCarga" listener="#{Bean.activarPanelCarga}" /> </rich:select> <h:panelGrid columns="1"> <h:panelGroup id="seccionCarga"> <rich:panel bodyClass="info" titleStyleClass="rf-p-hdr" > <f:facet name="header"> <h:outputText value="Detalle del archivo Cargado" /> </f:facet> <h:panelGrid columns="2" columnClasses="columnOnCenter,columnOnCenter"> <h:panelGroup style="text-align:center;display:block;width:550px;height:35px"> <div align="center"> <rich:fileUpload id="upload" styleClass="top" . . . {code} The problem is that the FileUploader remains disabled, it is as if the panel had not been updated. Generally <a4j:ajax event="selectitem"> requests fail, this only in IE 11.0.4 (KB2925418) Currently there is a filter to ensure compatibility with IE 8. When the page is loaded in developer tools (F12) the IE8 compatibility option is set correctly. The configuration of the environment is: Richfaces 4.0.0. IE11 JSF2 Eclipse Kepler Is there any way to correct the problems with these ajax requests?
