Nested jQuery $.when
javascript, jquery, jquery-deferred
Solution
You never actually return the promise objects created by `a2()` and `a4()` from the callback; this effectively returns `null`, which apparently counts as a completion for `$.when` purposes:

Problem
Essentially I am tring to write this: ``` var async1 = $.when( a1() ).then(function(){ a2() }); var async2 = $.when( a3() ).then(function(){ a4() }); $.when(async1, async2).then(function(){ console.log("complete"); }); ``` But at the moment when a1 and a3 have executed the function considers itself resolved. I put together the same example in a fiddle: http://jsfiddle.net/Z7fzR/
