may I have a last question? 
consider the following code:
function f () {
someGrid = new dhtmlXGridObject('someGridContainer');
// additional someGrid settings...
someGrid.loadXML("url", function () {
console.log('inside loadXML');
});
console.log('after loadXML');
}
Function f() is called and loadXML() function is being executed inside it... May we leave function f() during the execution of loadXML() ?
