Bug 121084 [jar packager] Next and Finish buttons are disabled if project is selected by keyboard
Next button is not enabled if keyboard is use to select file. How to reproduce : 1. in a Java project, in Package Explorer make JRE System Library the current item 2. From keyboard select alt-f,o (export wizard) 3. On select pane, press Enter 4. On second pane, (the Finish and Next buttons are disabled), select a project using arrow key and space to select projet. --> Finish and Next buttons are still disabled... Workaround : - Use mouse to select project in second pane.
