Clicking "Finish" with LinkMode set to LinkMode.ALL did not check the onAdvance() methods of the intermediate steps
 removed debug output
When removing wizard steps and adding new wizard steps again, the old ProgressBarItems are reused. However, the ID of new step may be different than the one of the old step. When clicking on a step, an obsolete ID is then sent back to the server and the navigation fails. The fix is to update the ID from the variables.
