Form attribute handler which has been configured in 14.1 for the form has stopped working after the upgrade to version 14.2.
There are no errors on screen and no errors in the log.
This is probably due to the usage of jQuery library.
Statements like $(...)will not work.
jQuery is not available in the form context. It is not imported anymore.
Use 'angular.element' instead of the '$'.This will use the angular library that contains a version of the jQuery library.
