Changing model property source
How about implementing a ContentProvider? This is a common way to read information from an external system and display them as content.

Another common approach is to have a scheduled job that reads your external system and creates content in Episerver. This way the content will still be available even if the connection to your external system fails.

I'm trying to change model property data source. By default it is obtained from EPI tables by DefaultContentProvider class and with this approach we got some efficiency problems.
I found two possible solutions (none of them worked so far):
1. In EditorDescriptor fetch data from external source and pass it through metadata. Hack dojo widgets to handle data from metadata. Ommit parameters that come to _setValueAttr (method that handles input change) and set there values from metadata. This failed because I'm blocking user inputs by this.
2. Replace DefaultContentProvider with custom one created by me. This provider would have logic to hadle custom properties. This failed because I cannot replace DefaultContentProvider.
There are also some AOP technics but really I don't want to hack EPI so much.
Any thoughts how this can be done?
