the codes I used for synchronous call is just set async: false, but it stopped working as it used to.
at async: false for Ext.Ajax.request ({...}), asynchronous call is undertaken. how should
I get synchronous call back ?



Ext.Ajax.request ({
url: url2use,
params: {},
method: 'GET',
async: false,
scope: this,
success: function (result, request) {
var jsonData = Ext.util.JSON.decode(result.responseText);
failure: function ( result, request) {'Ajax Request Error', 'Failed to get information on SNP<br/>and use default setting instead' , 5);
callback: function( result, request ){
