>
> On installation wizard, multiple clicks on the "Next" button can cause
> skipping of steps. The timing of the 2nd click decides if that click will be
> processed again or not. The following JIRAs had the same issue:
> AMBARI-7195
> AMBARI-7315
> The fix for the above issues helps to resolve most part of the problem. But
> if the user happened to click again at the point when the last callback
> function has just completed (and thus, has made the "Next" button clickable
> again) but the next step has not yet completed its rendering, then the 2nd
> click gets processed again. The "current step" was already updated in the
> code to point to the next step, from the 1st click. So when this 2nd click
> calls the "next" function in the router, the subsequent step of the "current
> step" gets set as the current step. As a result we skip steps.
