[ http://jira.jboss.com/jira/browse/RF-899?page=comments#action_12418725 ] Marine Wacheux commented on RF-899: ----------------------------------- Hi, I have the problem with "a4j:commandButton" component in RichFaces 3.1.5 : it renders sometimes two attributes "class". It's a blocking problem, as HTML isn't correctly formatted, and so can't be converted to PDF, for example : org.xml.sax.SAXParseException: Attribute "class" was already specified for element "input". Here is source code : <a4j:commandButton id="btnAjouter" value=" " title="#{msgG.Ajouter}" disabled="#{suiviMedicalHospitForm.modifOuCreationEnCours}" action="#{suiviMedicalHospitController.ajouter}" ajaxSingle="true" reRender="panelListeSuiviMedical,panelCreationOuModif" styleClass="BTN_AJOUTER" style="float:left;"/> And HTML generated : <input class="BTN_AJOUTER" id="body:formSuiviMedical:tableSuiviMedical:btnAjouter" name="body:formSuiviMedical:tableSuiviMedical:btnAjouter" onclick="A4J.AJAX.Submit('_viewRoot','body:formSuiviMedical',event,{'parameters':{'body:formSuiviMedical:tableSuiviMedical:btnAjouter':'body:formSuiviMedical:tableSuiviMedical:btnAjouter'} ,'actionUrl':'/gcm-web-patients/faces/jsp/operatoire/SuiviMedicalHospit.jsp?javax.portlet.faces.DirectLink=true'} );return false;" value=" " class="BTN_AJOUTER" style="float:left;" title="Ajouter" type="button" /> Is there a workaround for this ?
