normally when a method is not found I copy it from the class to the empty copy so slowly it gets automagically filled up. This is fun you see the result of your actions live. So normally I should not have the problem you describe. In fact the first thing I tried was to inspect the object and it worked wonderfully .

Now may be Morph is more vicious

Well for the objective C bridge

I used ProtoObject as the super class of the ObjectiveCObject and supplied doesNotUnderstand: to forward messages to the Objective-C plugin for dispatching Obj-c messages.

In attempting to work with instances of ObjectiveCObject I found I had to implement about 20 support methods so that you could inspect, explore, or recompile. Otherwise tapping inspect sends to you la-la land... Maybe there is a useful clue somewhere in there.

Hi

I wanted to see what is used in Morph so I did the following

Define a subclass of ProtoObject and redefnied DNU as follow

doesNotUnderstand: aMessage

| sel category | sel := aMessage selector. Transcript show: 'Does not understand ', aMessage selector printString ; cr. category := (Morph organization categoryOfElement: sel). self class compile: (Morph sourceCodeAt: sel) classified: category. ^ aMessage sentTo: self.

It works if I copy from Object but not from Morph does any of you have an idea.

Hello Stef, i designed own little thingy to intercept any message sent to an object, including #DNU. See, if it can be useful for you. As an example there is a subclass (CVMsgHandlingProxy) which i'm using to write an inline code to handle messages right in place where i creating a proxy: superReceiver "lambda, when reducing , sends #perform:withArguments: , and we doing trick by evaluating perform..inSuperClass" ^ CVMsgHandlingProxy onMessage: [:msg | msg selector == #perform:withArguments: ifTrue: [ self receiver perform: msg arguments first withArguments: msg arguments second inSuperclass: self receiver class superclass ] ifFalse: [ self receiver perform: msg selector withArguments: msg arguments ] ] what is cool in this method: suppose you have a code like following: proxy := (someObject asSuperReceiver). and later you sending a messages to it: proxy foo. Now, the trick is, that in the end, a message #foo will be sent to original 'someObject' , but using its superclass (same semantics, as you using super foo). What is cool in CVMsgHandlingProxy, that you don't need to declare a separate class each time you need to have different proxy behavior.. you just write: makeProxyFor: object ^ CVMsgHandlingProxy onMessage: [:msg | msg sentTo: object ] 2009/2/27 Stéphane Ducasse <stephane.ducasse@inria.fr>:

I have to think :) Right now it freezes hard :)
