Summary: Moved LzTrack from legals to 4.0
New Features:
Bugs Fixed: LPP-4271
Technical Reviewer: ben
QA Reviewer: (pending)
Doc Reviewer: (pending)
Documentation:
Release Notes:
Details:
The current 4.0 version of /services/LzTrack.lzs is the original merge of
LzTrack.js and LzTrack.as. There was a fix to help mouse click that didn't make
it to 4.0 (r5190). I ported LzTrack to the new class system (r5298) and this is
the version I'm submitting for review. This brings this file up to the latest
legals version.
I wouldn't worry too much about reviewing the code as it has already been
reviewed by Tucker. The important thing is that it greatly improves mouse click
behavior in components.
Tests:
combobox: components_sampler in dhtml/swf
list: list_example in dhtml/swf
