Greetings Everyone -
It is my pleasure to announce the availability of Ext JS 4.2.0 Beta 2! The bits can be found here:
We have started a minor reorganization of our CDN structure to cleanly separate products and their beta releases.
The CDN location for this beta build is as follows:
We will be copying older versions in to this structure (and maintaining their old locations) in the coming days.
On to more interesting topics.
Tree / TreeGrid
In this beta we have completed our performance improvements of the grid-family for the 4.2 release with the Tree and TreeGrid.
For starters, the new buffferedrenderer plugin now works with Tree and TreeGrid! By minimizing the DOM footprint, a tree can now contain a much larger number of nodes. Beyond this, tree expand and collapse processing has been optimized. Event bubbling in tree nodes has also been optimized to avoid firing events "up the tree" in situations where there are no listeners present.
All of this should allow trees to remain responsive even with large data sets.
We have added the ability for a controller to handle events fired by stores or other controllers. The selection syntax to select from non-components is much more limited than a full ComponentQuery. For example, in your controller you can now do this:
Enjoy and let us know what needs squashing!
component: // same as "this.control"
