Status: RESOLVED INVALID

(Core :: DOM: UI Events & Focus Handling, defect)

Description

[Masayuki Nakano [:masayuki] (he/him)(JST, +0900)]

We cannot use dispatchEvent in Javascript(see testcase).
I think that it is regression of bug 296704.
It blocks bug 259454.

See this testcase.
focus is set to first anchor, press enter.
If the javascript code is successed, you can show the alert dialog that text is
"success". But if the code is failed, you can see this message in Javascript
console.

Error: uncaught exception: [Exception... "Component returned failure code:
0x80070057 (NS_ERROR_ILLEGAL_VALUE) [nsIDOMEventTarget.dispatchEvent]" nsresult:
"0x80070057 (NS_ERROR_ILLEGAL_VALUE)"

20050621 build doesn't have this problem. but my build that is from CVS is
failed this.

This bug is blocks bug 259454 that is very important bug for CJK users. Please
hurry up to fix this regression!

Specs say that you can't dispatch an event already being dispatched.

Comment 5

[Masayuki Nakano [:masayuki] (he/him)(JST, +0900)]

Then, if I want to fire the event, should I just do what?
See bug 259454, I want to fire the keypress event in anchor element when user
press key in find toolbar.

MailTab and restoreTab doesn't work properly and leaves this error message even in 9.0.3 version. How can it be solved?
