I have a bare-bones example of what looks like a bug, but I’m not sure:
I have a simple application controller with two properties, one computed (outValue) and one not (inValue), with outValue dependent on inValue. Both are displayed on screen in edit boxes. If I modify inValue, the display of outValue updates as expected. However, if I so much as touch the outValue edit box (I just have to set focus to it), the link is broken, and changes to inValue no longer trigger the code that updates outValue.
I can make it work by changing the function declaration for the computed property from
outValue: function(key, value)
With that change, it works fine. Unfortunately, unless I actually reference key or value from within the function, the minifier in ember-app-kit strips out the arguments, and I’m back where I started.
Bug? The problem occurs in the latest beta as well as 1.3.1.
