-

this question can considered extension of how show error message in liferay portal?

working on ext plugin in liferay 6.1 , customizing updatelookandfeelaction, putting error message sessionmessages.add(request,"custom-error-msg"); seems portlet lifecycle cleans session in portalrequestprocessor.java(line 186) deleting session message well. normal your settings saved successfull rendered how can stop further execution in custom updatelookandfeelaction , render error message on /html/portlet/portlet_css/view.jsp

i have added <liferay-ui:error key="custom-error-msg" message="custom.error.msg" /> in view.jsp

i think read somewhere have create hook , customize end.jsp. right approach? suggestions , directions appreciated.

i had override look_and_feel.js following:

var savehandler = function(event, id, obj) {                     var ajaxresponsemsg = instance._portletmsgresponse;                     var ajaxresponsehtml = '<div id="lfr-portlet-css-response"></div>';                     var message = '';                     var messageclass = '';                     var type = 'success';                     ***var customerrormessage = obj.response;***                      ***if (obj.statustext.tolowercase() == 'ok' && obj.response != '') {                         type = 'customerror';                     }***                     if (obj.statustext.tolowercase() != 'ok') {                         type = 'error';                     }                     if (type == 'success') {                         message = liferay.language.get('your-request-processed-successfully');                         messageclass = 'portlet-msg-success';                     }                     ***else if(type == 'customerror') {                         message = customerrormessage;                         /*message = liferay.language.get('custom.error.msg');*/                         messageclass = 'portlet-msg-error';                     }***                     else {                         message = liferay.language.get('your-settings-could-not-be-saved');                         messageclass = 'portlet-msg-error';                     }
