App no longer reliable after Firefox 25.0.1 forced update
Hi Sencha community,
Has anyone also experienced some problems after the forced update?
Is there a way to override and make ext 4 behave as if the browser were Firefox 21, for example?
I would be happy to give some more info if necessary.
Sounds like a missing require somewhere, but some class somewhere is requiring it and sometimes loads first, hence your race condition.
"c is not a constructor" is generally caused by a class that could not be found at instantiation time, in my experience.
Are you using new, or Ext.create to instantiate btw?
The latter would tell you more...
