1312688 - Cannot type some special characters in input text fields in Flash/Flex content with various keyboards (Polish, French)

Status: RESOLVED DUPLICATE of bug 1293505

(Core Graveyard :: Plug-ins, defect)

Description

[wezu84]

User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/54.0.2840.71 Safari/537.36

Steps to reproduce:

1. Upgrade to the latest version of Firefox or install a clean version of Firefox 49 (49.0.1 or 49.0.2) - 32bit or 64bit.
2. Tested on Windows 7, 8.1, 10.
3. Run any Adobe Flash/Flex based website/content on browser.


Actual results:

The problem is that you cannot type any polish characters (ąćęłńóśźż) in any inputs/text boxes in Flash/Flex content.
The problem appears only in the latest versions of Firefox (49.0.1 or 49.0.2) in all adobe flash player plugin versions: 19, 20, 21, 22, 23.


Expected results:

There is a solution but works only temporarily on Firefox 49 (49.0.1 or 49.0.2).
After upgrade/install to the latest version of Firefox we have to click "Refresh Firefox" button in the browser or Firefox website. 
Then typing polish characters works in Flash/Flex content.
But when we close the browser and reopen Firefox it again stopped working typing polish characters.
We have to again click "Refresh Firefox" button again.
However everything works fine (you can type any polish characters) and that problem does not exist in earlier versions of Firefox (47 or 48) in all of adobe flash player plugin versions: 19, 20, 21, 22, 23.

Firefox is doing the same with special characters in French (but only with altGr) like @.
Tested on windows 8, 10.

Could you provide a website or a testcase with input in Flash object?

You can test on : http://www.ardisialabs.com/demo/

Yes this is exactly the same problem.

Comment 5

[yannick.liepold]

By setting the 'dom.ipc.plugins.asyncdrawing.enabled' to false in about:config it works well on our side.

Comment 6

[wezu84]

Yes it works. Thanks a lot!

I have reported another bug with different solution:
https://bugzilla.mozilla.org/show_bug.cgi?id=1312902

Comment 9

[Jim Mathies [:jimm]]

Makoto, can you help diagnose this? My understanding is that polish input should work fine both in windowed and windowess mode. Possibly there's a bug here with text input handling?

Comment 10

[Makoto Kato [:m_kato]]

If this issue is on windowed mode too, I think that we need investigation with Adobe side.  And on windows less mode, it may be our event handling.

Nakano-san, I don't have EU keyboard (I should buy it :-)), so could you investigate or confirm?

Comment 11

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

Yep, I'll try later but EU keyboards are not so special. JIS keyboard have all keys which EU keyboard have (JIS keyboard is the keyboard which have most keys in the world). JIS keyboard doesn't have only Brazilian ABNT keyboard's C1 key (a key at right of left Shift), C2 key (separator key on Numpad, Mac JIS keyboard has it, though), Korean IME keys (Mac JIS keyboard's Kana and Eisu keys are them, though).

Comment 12

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

I assume that the report is, AltGr + foo doesn't work.

However, I don't see any problem with Firefox 49.0.2/Nightly, Flash Player 23.0.0.185 on Win10.

Hmm, that sounds very odd. Do you install some add-ons? If some add-ons consumes some keyboard events before plugin only when AltGr is active, it's possible to reproduce, but I don't have any idea what kind of add-on wants to do for what purpose...

When you do "refresh", Firefox will restart automatically, then, only on the restarted Firefox, it works, but after restarting Firefox manually, it won't work, right?

Then, do you nothing other than testing it? (If so, I don't have any idea...)

Comment 14

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

And I have another question, when you press and release AltGr in Flash Player, does menubar of Firefox become active (like left Alt key)?

Comment 15

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

And AltGr key is same as left Ctrl + left Alt. So, what happens when you use them instead of AltGr?

No I don't install any add-ons. I install only pure Firefox and flash player plugin.
And yes when I click "refresh", Firefox will restart automatically, then, only on the restarted Firefox, it works, but after restarting Firefox manually, it won't work".

The effect is the same. Polish chars won't work.

Comment 18

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

Thank you for the information, but I still don't have any idea what happens on your environment. The native key message handler won't depend on profile. So, I guess that it must be that the key events are consumed by somebody depending on profile...

If you don't mind to use Nightly, could you post a log file with Nighty build? (Nightly has a lot of improvements of native key message handling and can log the behavior.)
https://nightly.mozilla.org/

You need to set env before launching Nightly:
MOZ_LOG=NativeKeyWidgets:4,KeyboardLayoutWidgets:4
MOZ_LOG_FILE=<path to log file, e.g., c:\users\<user name>\fx.log>

Then, all key messages are logged. So, don't type anything your private info, such as password, and please don't use keyboard shortcut keys like Ctrl+V, such log is just a noise. Use context menu instead to open a test page. Then, you can attach the log file to this bug from above form (if you post a log file, nobody can remove it forever, so, be careful about the logged information).

Comment 19

[Loic]

I can't reproduce the issue (from comment #3, when typing @ in the input field) in FF50+ with asyncdrawing enabled.
Fix range:

Fixed by bug 1293505.

The reporter should download Beta and test again.

Comment 20

[Loic]

wezu84, can you download Beta and confirm it's fixed on your side:
https://www.mozilla.org/fr/firefox/beta/all/

Try with both situations "dom.ipc.plugins.asyncdrawing.enabled = true/false" (restart between both).

Hey Masayuki, did you test in 49.0.2 with 'dom.ipc.plugins.asyncdrawing.enabled' set to true? the .2 point release disabled that and I think this bug might be related to async drawing.

https://wiki.mozilla.org/Plugins/Async_Drawing_Triage#Testing

You can also test on nightly which has async drawing enabled by default.

Yes, but I cannot reproduce this bug.

And this test page has each type of input field of flash player:
http://emk.name/test/swftxt.html

I can input "ą" in all forms except swf4's forms.
