[richfaces-issues] [JBoss JIRA] Resolved: (RF-2323) Mouse over input in dropDownMenu causes NS_ERROR_XPC_JS_THREW_STRING in Firefox

Mouse over input in dropDownMenu causes NS_ERROR_XPC_JS_THREW_STRING in Firefox ------------------------------------------------------------------------------- Key: RF-2323 URL: http://jira.jboss.com/jira/browse/RF-2323 Project: RichFaces Issue Type: Bug Affects Versions: 3.1.4 Environment: Firefox 2.0.0.12, MyFaces 1.1.5 / Tomahawk 1.1.6, Facelet Reporter: Paul Iov Assigned To: Pavel Yaschenko Fix For: 3.2.1 Attachments: screenshot.jpg In 3.1.4GA NS_ERROR_XPC_JS_THREW_STRING is thrown 3 times after mouse entered the input's rectangle and then 3 times on mouse out. After this menue becomes not hidden even if mouse pointer leaves the menue rectangle. Normal "behaviour" is then restored again on any successfull mouseover event of menue. Another side effect is that if this happens inside of shown menuGroup (see screenshot ), this group becomes hidden, but the focus remains by focused input (if some was focused) and the keyboard events are still sent to it. Henady has proposed how to fix it for contextMenu in menu.js ( http://www.jboss.com/index.html?module=bb&op=viewtopic&t=130502 ), but this doesn't solve the problem with dropDownMenu completely (after this the exception is thrown 2 times and not 6 as before).
