Bob Harner commented on TAP5-1777:
----------------------------------
Upon further investigation, this bug appears to be caused by old JavaScript
from Tapestry 5.2.x, left in the browser cache after upgrading to Tapestry
5.3.x. Clearing the browser cache (or pressing Control-F5 in Windows, or
Command-Shift-R on a Mac) seems to resolve it in the cases that I and some
others have seen.
If any one sees this bug after clearing or bypassing the browser cache, please
comment. Otherwise we'll probably close this issue after updating the release
documentation.
