Cross frame problems

[Stig Runar Vangen]

I'm using CkEditor in a GWT integration. This worked well until I just tried to update to the latest version 4.2 from version 4.0.1. I tracked this problem down to the isArray method in the tools.js file. The instanceof method works if you receive data from the same frame as where you are using the editor. When you send an object to an another frame, the instanceof Array method will no longer work. More details on this problem, and how to solve it is described here:

​http://perfectionkills.com/instanceof-considered-harmful-or-how-to-write-a-robust-isarray/

In short, this seems to be the best way to detect if an object is an array:

function isArray(o) {

return Object.prototype.toString.call(o) === '[object Array]';

}

I should also probably mention that GWT always loads all code through an iframe, which makes the current editor incompatible with a GWT environment.

This issue also occurs in some of our products and is currently a blocking issue for upgrading to CKEditor 4.2. Can you please prioritize this issue for an upcoming release?

@stigrv, thanks for the suggestion. It should not be a big deal to change this, in fact.
