WebView in a modal window

[Konidaris Christos]

Hi,

I have a simple window with a WebView and an NSButton that I want to display as 
a modal window. The window is loaded from a NIB using MyCompanyAlertController, 
that also acts as the WebView's delegate (set in the NIB).

When run as a sheet in my main window (using method showAlertInSheet: below) 
the webView loads its contents and calls its didFinishLoadForFrame: delegate 
method as expected. I cannot make it work when I am trying to display the 
window as an NSApp modal window with method showAlertModal: below. What is that 
I am missing? I am using Xcode 7.1 on OS X 10.11.1 and deployment target is set 
to 10.9.

Thanks for any help,

- Christos Konidaris
