FF 18 problem?

[pzs1]

And I can confirm that this is happening with my application as well, and that the workaround Holger does not help.

Try to write

try{}catch(e){} 

line directly into ext class, after the following lines:

callOverrideParent = function () { // line 36 in ext-all-dev.js (4.1.1)
callParent: function(args) { // line 5885
callParent: function(args) { // line 6179 

It helped me.

The reason it's not reproducible is because it happens during some JIT compiling, so it's not really something we can "fix", since the symptom happens almost at random. The reason the try/catch works is because methods with try catch blocks don't get compiled.

The FF bug is here: https://bugzilla.mozilla.org/show_bug.cgi?id=818023

Thx... It helped me too...

The Try/catch temporary patch works for us as well.

Who needs to release a fix for the core issue? Mozilla or Sencha?

Ideally Mozilla.

Take a look at the Bugzilla report evant mentioned. It looks like Mozilla are still debating whether or not to include a fix in 18.0.1 dependent on 'user feedback'. Anyone who's keen to see this fixed quickly might want to voice their support to Mozilla.

Thx for these workarounds...but what if I use the compressed product version? We use ext-all-dev.js of course only for development...

We are also starting to get the problem reported to us. Seems like the auto update in Firefox can take a few days to happen.

Is there any chance of a temporary fix for the compressed files, maybe some global place the try catch can be added?

I'd asked for further information about integration state of the patch in the next releases. Unfortunately, the current patch has raised a regression test last night and therefor an automatic pull of the patch.

I give you a quote about the current Mozilla issue 818023:

The change has since been backed out for test regressions (it will be in today's Nightly, but not after that, once the backout merges in later today), however you can test a build with it at:

Win32:http://ftp.mozilla.org/pub/mozilla.org/firefox/tinderbox-builds/mozilla-central-win32/1357912691/firefox-21.0a1.en-US.win32.zip

OSX:http://ftp.mozilla.org/pub/mozilla.org/firefox/tinderbox-builds/mozilla-central-macosx64/1357912691/firefox-21.0a1.en-US.mac.dmg

Linux32:http://ftp.mozilla.org/pub/mozilla.org/firefox/tinderbox-builds/mozilla-central-linux/1357912691/firefox-21.0a1.en-US.linux-i686.tar.bz2

Linux64:http://ftp.mozilla.org/pub/mozilla.o...x86_64.tar.bz2

They will track this for the next release if possible. This means the fix for 21 would be applied for 18, 19 and 20.

Create and run the following php code:

<?php

$fn_in = "ext-all.js";
$fn_out ="ext-all2.js"; 

$f = file_get_contents($fn_in);

$f = str_replace('d=function(){var i=d.caller.caller;r', 'd=function(){try{}catch(e){};var i=d.caller.caller;r', $f);
$f = str_replace('callParent:function(d){var e;r', 'callParent:function(d){var e;try{}catch(e){};r', $f);
$f = str_replace('callParent:function(e){var g,d', 'callParent:function(e){try{}catch(e){};var g,d', $f);

file_put_contents($fn_out, $f);

print "DONE";

You can also implement it like this

Ext.onReady(function(){

   if (Ext.firefoxVersion >= 18) {
      var noArgs = [];
      Ext.override(Ext.Base, {
      callParent : function(args) {
         var method, superMethod = (method = this.callParent.caller) && (method.$previous || ((method = method.$owner ?
method :
method.caller) && method.$owner.superclass[method.$name]));

         // Workarround for Firefox 18. I don't know why this works, but it does. Perhaps functions wich have
         // a try-catch block are handled differently
         try {
         } catch (e) {
         }

         return superMethod.apply(this, args || noArgs);
      }
     });
  }
});

This way you don't need to change the ExtJs Files...
