Problem with IE9 and CKEditor in Vaadin windows

[GoogleCodeExporter]

Hi,

We have a little issue with CKEditor and IE9 when CKEditor is opened inside a 
Vaadin Window.

When we open the window several times (around 20) it stops working in IE9.

This is due to the fact that IE imposes a max number of 32 css files and 
CKEditor tries to add the new CSS files each time we open it.

What steps will reproduce the problem?
1. Opening the CKEditor in IE9 multiple times inside a modal Window

What is the expected output? What do you see instead?
Blank editor

Thanks a lot,

Thomas

We're not sure how to fix this. Perhaps you can also post in the vaadin forums 
to see if there are solutions to this sort of issue.  

I recall special code to load the library JS once, but not sure why the number 
of CSS files would increase over time.  I mean, you'd figure it might request a 
CSS file with an HTTP GET, but it seems odd that repeated requests for it would 
increase the number of CSS files and not just replace the contents or even get 
an HTTP status 304 indicating the file hasn't changed.  You might check your 
web server access log and see what the responses are for the CSS file requests.

No response or follow-up on the problem, which sounds like an old IE9 issue 
(upgrade to IE11 is recommended for security reasons alone) and not an issue 
with this project.  It's also possible it's a CKEditor issue, but it sounds 
like IE and trying to open lots of editors.  For now, we'll close this as not 
going to be fixed, but if more information comes in that suggests a way to 
resolve this, we'll be happy to re-open it.
