Question

when().then() pattern in the following situation:

$.when(setServerValue("true"))
    .then(function(){
        console.log('done setting new value');
        performSomeOperation();
    })
    .fail(function(){
        alert('server value not set!');
    });

var setServerValue = function(newValue){
    return $.post('http://myURL',{key:newValue});
};

The problem here is that the ‘then’ or ‘fail’ operations are never called using a $.post() operation. I’ve successfully used this approach with $.get() operations, and if I understand the API docs correctly (apparently not), this should also work for $.post operations.

Can anybody help me with this? Thanks!

The problem is that setServerValue is not defined as function when you call it. Move your definition of setServerValue above the $.when call.
