what is this? I dont see docs for OnWebUISend anywhere. If you are just trying
to handle a chrome.send call, create a handler class and use
RegisterMessageCallback

[Scott Franklin, 2011/06/29 23:47:08]

It's defined in content/browser/webui/webui.h. I pulled this from
sync_internals_ui, which looks like it handles a single message manually before
passing the rest off to another class.

Creating a handler does indeed appear to be the correct way of doing this.
