javascript - 'length' is null or not an object -

-

button click, executes method, takes long (> 1 min time), populates grid within update panel. asyncpostbacktimeout="600" set, should plenty of time.

do locally , short , long duration works fine.

when deployed iis 7 short duration, don't experience trouble @ all.

however, longer ones give me following error:

edit: error on browser javascript console

message: 'length' null or not object line: 2 char: 18021 code: 0

edit: deployed on test server therefore below link not work straight off bat.

uri: http://epic/scriptresource.axd?d=3tx7t6ewzexoeemuaa1e9w3jsjacoprdefijbekiyjsg8amewhqtpedv31v-r-fkisdfa9pg2hupavqozf_hy7_e2fwgzwu07o7n-3j58ttvujekcpgxwmmo-sjpxo4c0&t=ffffffffbd2983fc

i don't know length coming from, other javascript have this:

<script type="text/javascript" language="javascript">   function cancelclick() {         alert('changes have not been saved');     }      function startprocedure() {          document.getelementbyid("<%=lblexecute.clientid%>").innertext = "procedure executing";    }  </script>

you miss " @ end of = "procedure executing;!
