Hello,
I have the same issue which is discussed in the following link:
http://apache-wicket.1842946.n4.nabble.com/WicketRuntimeException-component-not-found-on-page-td3055902.html
I made a quickstart to reproduce it. Any idea on how to workaround
this behavior?
I'm using wicket 1.4.12, wiquery 1.1.2, and wiquery-plugin for tooltip
(other-plugins-1.1.jar).
Thanks,
Takeo Hosomi
Step1.
Use following source code to reproduce the problem.

Step2.
When clicking the paging navigator, quickly move the mouse to the
table region. Then sometimes following error messages are shown:
