Description James Clancey 2011-12-23 15:54:06 UTC
When you bind something that has 2 similar properties. You get the following error.

		[Export ("save")]
		bool Save ();

		[Export ("save:")]
		bool Save (NSError error);

The type `Parse.PFFile' already contains a definition for `selSave'

`btouch` SelectorField method does not create unique name with the selector ends with a ':' character.

The btouch fix can be easy (e.g. add a '_' to selectors ending with ':') but it requires to update all the non-generated code in monomac.dll and monotouch.dll (64 errors) to use the new selector names. OTOH it should have no impact outside the assemblies since the static fields are all private.

An alternative would be to build a selector name cache... but that will only slow down the tool without any real gain (now or later).
