How to dynamically set a value on a combo

It can happen that you have to set a value on a combo-box dynamically, and maybe even if the combo has never been opened (thus the store never loaded all the values). To correctly set a value and make the combo show the relative description you have to load the store and use the callback function to set the value:

myCombo.store.load(\{ callback:
    function()\{
        myCombo.setValue(myValue);
    \}
\});

Watch out if you have to do the same process inside a loop: The store.load is an asynchronous method and the response might get back after many loop cycles! To correctly set a value inside a loop you have to create a scoped function like this:

for(var i = 0; i < 100; i++)\{

...

(function(i)\{
    // Same code as above but inside the scoped function
    myCombo.store.load(\{ callback:
        function()\{
            myCombo.setValue(myValue[i]); //This i is
        \}
    \});
\})(i); //This is the i of the cycle

...

\}

This way the i will not change
