Bug 23447 Java super-class name does not carry on to dialogue box [code manipulation]
From WSAD Customer: When creating a new Java Class, when an incomplete super-classname is entered in the dialogue box and then the Browse button is clicked, nothing that appears in the Choose a type field. Ideally, it should have the incomplete name typed in the previous super-class field. How to recreate : In the Java perspective, - File -> New ->Class - In the resulting dialogue box, type "JPan" in the 'Superclass' field. Now click on Browse. - Ideally, the dialogue box that just opened up should already have JPan written in it and hence the list of selectable classes would be shortened.
