When you try to import an example in KIE Workbench, select custom repository type option and enter invalid URL, an error dialog is shown. If you close this dialog, you will get to the Project tab of Import Example dialog where you will see Fetching Repository... text. This might be confusing since no fetching is happening after the error. The dialog should stay at Repository tab, highlight the repository URL field with red color and say that repository cannot be cloned.
