Methods +readable/writableTypes

[Germán Arias]

Hi,

Some weeks ago I tried to solve a problem with native Open/Save panels at 
WinUXTheme. These panels don't have "accessory view", so the user can't select 
other type of document. Then I tried use the methods +writableTypes and 
+readableTypes in NSDocument. However, these methods not always return the 
corresponding types. I tested WinUXTheme (my local copy) with Ink, Gorm and 
Gemas. Ink works perfectly. Gorm only show the types at Open panels, but in 
Save panels +writableTypes return an empty array. In Gemas both methods, 
+readableTypes and +writableTypes, return an empty array. I tested this on my 
GNU/Linux machine, and I can confirm that these methods sometimes return an 
empty array. Even when readable/writable types are clearly declared at 
info.plist. Is this the expected behavior?

Regards.
Germán.
