Missing getContent() Function?

On our site, we have installed a fairly popular plugin called Essential Grid. We had been using Essential Grid on our site for a while before installing CK Editor. After installing CK Editor, we started having problems with the back-end admin part of Essential Grid.

I contacted the developers of Essential Grid and they were very helpful in tracking down the issue. This is the response that I received from the plugin developers:

So we installed it on our dev system and can confirm now that the hook that they do to overwrite tinyMCE is missing some functionality.

The function getContent() is not available and producing this error. Unfortunately they do not deliver any comparable function to this. I can modify this on your server so that the version you are using will work, but all editors inside of essential grid will most likely not work properly then. Other than that, you could ask the support from the plugin for an equivalent for getContent() and if it is not existing, if they are willing to add it to their library.

As a temporary fix, we’ve modified our essential grid plugin to not call getContent() which, as mentioned above, breaks Essential Grid’s editors. The other downside to this is that we need to manually make this change every time Essential Grid is updated.

So it would be nice to have this solved within the CK Editor plugin so that everything can work in harmony. Is there any way that a fix can be applied to CK Editor for this?

Thanks for the help.
