    Resolution: Cannot Reproduce Bug


I successfully registered a onheadermousedown and onheadermouseup listener with the metamer test application, and the listener was executed without error.

This issue report does not contain enough information to isolate the error.

Feel free to re-open the issue, with a Short, Self Contained, Correct (Runnable), Example demonstrating the problem, and we'll be more than happy to take a deeper look into it.

> On rich:tab we use the attribute "onheadermousedown" which call a javascript function defined by a4j:jsFunction. When we switch tab, we got the following error:
