This release fixes a number of small bugs in both QuickUI and the QuickUI Catalog.
The most significant change is in the Control constructor. QuickUI previously went through a lot of trouble to subclass jQuery. This code involved patching up a class when an attempt was made to instantiate it so that the result would be acceptable to jQuery. Specifically, the resulting patched-up class could be instantiated without requiring the “new” keyword. This code was quite complex and brittle, and was eventually broken by a change to the CoffeeScript 1.5 compiler. The CoffeeScript folks graciously backed out that change in CoffeeScript 1.6 so that QuickUI could continue to function.
Meanwhile, a workaround had already begun to drastically simplify the Control constructor — in exchange for dropping the ability to instantiate a control class’ constructor without the “new” keyword. As it turns out, QuickUI controls are typically instantiated via the framework itself, either declaratively through Control JSON or imperatively by invoking Control.create(). Only the framework needed to directly instantiate a control class, and so the framework source was updated to always make use of the “new” keyword.
In general, despite this constructor change deep in the framework, QuickUI developers should generally observe no changes in framework behavior.
The QuickUI Catalog has a few small bug fixes, but the version number has been bumped to 0.9.4.0 to keep in sync with the new version number for QuickUI 0.9.4.
