> 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.
