[Pharo-users] a 'doesNotUnderstand' message that I do not understand...

Hi all, Exploring the system browser (Pharo 2.0), I see that there exists a class called TextEditorDialogWindow; as this name sounds interesting to me, I want to test one, and I see that there is only one method in the category 'create': this method is called newTextEditorMorph. So, I send the message newTextEditorMorph to the class TextEditorDialogWindow, daring a: TextEditorDialogWindow newTextEditorMorph At the 'Do It', I get this error message: 'TextEditorDialogWindow class(Object) doesNotUnderstand: #newTextEditorMorph' That's what I don't understand: If the class has a method called this way, why does it not understand the corresponding message? What did I miss? Alain
