confirm on trunk 20091003031247 on Mac OS X 10.6 with Andy's sample. Silverlight 3 for Mac OS X doesn't support inline edit of IME. When I commit IME strings, first byte will be lost. Also, backspace key doesn't work when Japanese IME is turned on. I add Nakano-san to CC.

Thank you, Kato-san. Steven, is there any idea of the cause?

> Steven, is there any idea of the cause? Not off the top of my head. The fact that IME doesn't work on FF 3.0.1, which doesn't have my patch for bug 357670, indicates that patch isn't at fault. Kinda looks like the Silverlight 3 developers have only just started testing IME with Silverlight 3 on Firefox :-(

> The fact that IME doesn't work on FF 3.0.1 I'm assuming this from the contents of comment #0, and that the "3.0.10" in the summary is a typo.

Steve, Have we had a chance to look at this issue? Do we know whether Flash made some kind of fix between Firefox 3.0.1 and 3.0.10? They were also broken between these releases. Thanks

Even in Safari, Silverlight 3 uses "input window" IME, not "inline IME". Even "input window" IME doesn't work in Firefox 3.0 and above. But it's broken in different ways before and after my patch for bug 357670 (which landed in Firefox 3.0.2). I'd hoped that my patch for bug 508898 might fix (or work around) this bug -- it doesn't. It will probably take me some time to debug this. Andy, I may find that I need more information about how Silverlight's IME support works internally. If so I'll ask here.

Steven, Can you tell us if there has been any special casing for Flash in the 3.0.10 release? Thanks

(In reply to comment #12) > Can you tell us if there has been any special casing for Flash in > the 3.0.10 release? Not explicitly. But I had to do some serious hacking to make things work properly in Flash -- which at the time (and until Silverlight 3 came out) was the only plugin that claimed to support CJK IME on OS X. See particularly bug 357670 comment #54. You should read carefully through my patch for bug 357670, and at least skim all the comments in that bug. I still haven't had a chance to get to this bug. I'm hoping for later this week.

Andy, is there any way to download earlier versions of Silverlight than version 3? I'd like to be able to test with Silverlight 2, but all I have are copies of different Silverlight 2 betas.

After *much* digging around, I've managed to find the following links to versions 2 and 3 of the "Silverlight Developer Runtime": "Silverlight 2 Developer Runtime" http://go.microsoft.com/fwlink/?LinkID=119973 "Silverlight 3 Developer Runtime" http://go.microsoft.com/fwlink/?LinkID=150227 I assume these will be adequate for my purposes. I couldn't find anything equivalent for Silverlight 1 ... but I hope that's too old to be relevant. You know, it's *really* annoying when a software publisher hides its older versions.

For all previous versions of Silverlight. http://go.microsoft.com/fwlink/?LinkID=92598 This link is actually found in http://www.microsoft.com/silverlight/resources/technical-resources/ but we need to work on SEO.

Thanks! The first link is exactly what I need. And yes, you guys do need to make this information easier to find :-)

Andy, your testcase appears to require Silverlight 3. If I understand correctly, Silverlight 2 didn't support CJK IME on OS X. But I'd still like to be able to test with a simple text box that works with both Silverlight 2 and Silverlight 3.

Try this sample http://silverlight.services.live.com/invoke/99030/ControlsDemo/iframe.html works with 2 or 3.

I'm having terrible trouble running either Firefox or Safari in gdb while a Silverlight plugin is loaded (in either Silverlight Developer 2 or Silverlight 3). The app tends to freeze up after hitting a single breakpoint. I'm testing on OS X 10.5.8. I've never seen this before. Certainly never with any plugin. Any idea what's going on, Andy? I notice that the IMETextBox.dll which comes with your testcase is a DOS/Windows executable (it starts with 'MZ'). Does this mean Silverlight "apps" run in some kind of interpreter, and could this be the source of the trouble?

'file' returns the following on it:

This is the way all Silveright applications are built. The applications include "managed" assemblies that are loaded by the control. The assemblies are platform agnostic. I'm going to try to get a dev on this thread to help you with your debugging issue.

(In reply to comment #22) Thanks. I imagine Silverlight apps use bytecode, something like Java apps. (Following up comment #20) Now I've seen the same problem on OS X 10.6.2. I've also seen the browser (with Silverlight running) freeze in gdb without setting (or hitting) any breakpoints at all. Needless to say, I'm probably not going to be able to help you unless we can find a way around this.

Gotcha! This bug is entirely Silverlight's fault. I've been banging my head against this for some time. Among other things I actually figured out how to hook Text Services Manager calls (like DeactivateTSMDocument()), and how to log a stack trace on each call (more on this in a later comment). I also added logging to Firefox's [ChildView processPluginKeyEvent:] (in ChildView.mm), which shows that Firefox is sending the correct keystroke information to Silverlight. But I forgot to try something really obvious -- set Firefox to use Safari's user agent string, and see what happens. Just now I did this ... and it makes the problem go away! Clearly Silverlight is using a different code path in Firefox, and clearly it's doing something wrong there.

I'm gonna reopen this and kick it to TE, then, since it's pretty important that Silverlight not be broken in Firefox.

Here's how to set Firefox to use Safari's user agent string: 1) Enter about:config in the Location bar. If prompted, click on the "I'll be careful, I promise!" button. 2) Right-click somewhere in the settings display (below the Filter box), and choose New : String. 3) Enter general.useragent.override as the preference name. 4) Enter the following (without line breaks) as the string value: Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10_5_8; en-us) AppleWebKit/531.21.8 (KHTML, like Gecko) Version/4.0.4 Safari/531.21.10 Here's a page that (among other things) displays your browser's current user agent string: http://www.gemal.dk/browserspy/basic.html

Here's a debugging patch that 1) hooks and logs the following Text Services Manager calls ActivateTSMDocument() DeactivateTSMDocument() DeleteTSMDocument() NewTSMDocument() TSMGetActiveDocument() 2) logs a stack trace on each of the above calls 3) logs the sending of keystrokes to plugins. Numbers 1 and 2 are substantial innovations -- if I say so myself :-) I don't believe #1 has ever been documented before -- in fact I wasn't at first sure it even was possible. And though #2 has been documented in principle (at http://www.cocoadev.com/index.pl?StackTraces, not by Apple), there's a potentially crippling "catch 22" that I had to learn to work around (the Symbolication framework can take a minute to initialize when used with Firefox). Here's a tryserver build made with my patch: https://build.mozilla.org/tryserver-builds/smichaud@pobox.com-bugzilla520312-debug/bugzilla520312-debug-macosx.dmg With my patch (and tryserver build), you can see a couple of the things Silverlight does differently when it thinks its running in Firefox or Safari: Only in "Firefox-mode" does Silverlight call TSMGetActiveDocument() and DeactivateTSMDocument() (from BitmapSource_SetSource in Contents/MacOS/agcore) when processing text input while doing IME. From #3 above, you can also see that Firefox sends exactly the same keystrokes to Silverlight in "Firefox-mode" and "Safari-mode".

INCOMPLETE due to lack of activity since the end of 2009. If someone is willing to investigate the issues raised in this bug to determine whether they still exist, *and* work with the site in question to fix any existing issues, please feel free to re-open and assign to yourself. Sorry for the bugspam; filter on "NO MORE PRE-2010 TE BUGS" to remove.
