[TIMOB-1972] click event inside tableview click event causes exception

Adding a click event inside another click event causes an exception.

I have just found this bug in the latest build, 1.4.2 / 30.09.2010. The 1.4.2 CI build released 21.09.2010 did not have this issue.

To see the issue in action, replace Resources/examples/animation.js in the KitchenSink with the following code:

http://gist.github.com/605647">Resources/examples/animation.js

Here is the error output:
