asp.net - Update panel, end request handler, no error object? -


all,

when upgraded asp.net 2.0 asp.net 3.5 , in custom end request handler, args.get_error() returns null (i traced way function sys$webforms$pagerequestmanager$_endpostback(error, response), error object null there too). happens on production server, on development machine works, error object. both win 7 machines, iis 7.5.

fyi: on server, log error, , clear via ctx.server.clearerror(); set asyncpostbackerrormessage on script manager.

**update: setting allowcustomerrorsredirect="false" on scriptmanager explicitly resolves issue. **

found on msdn little explanation:

https://msdn.microsoft.com/en-us/library/system.web.ui.scriptmanager.allowcustomerrorsredirect(v=vs.110).aspx

remarks

the asyncpostbackerror event raised when there page error during asynchronous postbacks. how errors on server sent client depends on allowcustomerrorsredirect property, asyncpostbackerrormessage property, , custom errors section of web.config file.

here's client script code handling ajax errors:

                    mgr.add_beginrequest(function(sender, args) {                         postbackelem = args.get_postbackelement();                         if (typeof(postbackelem) === 'undefined')                             return;                          targetpnl = self.gettargetpnl(mgr, postbackelem);                         $(targetpnl).addclass('updateprogress-started', duration);                     }); //beginrequest                      mgr.add_endrequest(function(sender, args) {                         if (typeof(postbackelem) === 'undefined')                             return;                          $(targetpnl).removeclass('updateprogress-started', duration);                          if (args.get_error() != undefined){                             var msg;                             if (args.get_response().get_statuscode() == '200') {                                 msg = args.get_error().message.replace("sys.webforms.pagerequestmanagerservererrorexception: ", "");                             }                             else {                                 msg = 'an unspecified error occurred.'; // error occurred somewhere other server page                             }                             args.set_errorhandled(true); // show error in our custom panel                            $(self._errtext).text(msg);                            $(self._errpanel).show();                         }                     }); //endrequest

by setting allowcustomerrorsredirect="false" on scriptmanager explicitly resolves issue.

serialization - Convert Any type in scala to Array[Byte] and back -

i have following question: i have variable value in program declared value. i want convert value byte array.. how can serialize byte array , back? found examples related other types such double or int, not any. this should need. it's pretty similar how 1 in java. import java.io.{bytearrayinputstream, bytearrayoutputstream, objectinputstream, objectoutputstream} object serialization extends app { def serialise(value: any): array[byte] = { val stream: bytearrayoutputstream = new bytearrayoutputstream() val oos = new objectoutputstream(stream) oos.writeobject(value) oos.close stream.tobytearray } def deserialise(bytes: array[byte]): = { val ois = new objectinputstream(new bytearrayinputstream(bytes)) val value = ois.readobject ois.close value } println(deserialise(serialise("my test"))) println(deserialise(serialise(list(1)))) println(deserialise(serialise(map(1 -> 2)))) println(deserialise(seri
