Support for BeforeShowNextStep?

[Luis-Arpasi]

Hi,

I have the scenario where i need to show a modal window before show the last step because the element for last step is in the modal window. When i try to show the window modal in onNext i got an error because the element was not found.

any solution to handle this?

Yeah, that's a pretty common use case. I'll try and get to it sometime this weekend.

Hey Luis, does your onNext callback load the contents of your modal through AJAX? "BeforeShowNextStep" is basically what "onNext" does. Just trying to figure out what your situation is.

Any updates on this?

I want "Create a Class" to be pointed at the Input box on the modal.... but since they come up together they end up like this.

Or somekind of timeout before displaying next..... Might fix this.

This seems like a bug... I was able to fix it by hoisting

if (doCallbacks) {
  if (direction > 0) {
    doShowFollowingStep = utils.invokeEventCallbacks('next', origStep.onNext);
  }
  else {
    doShowFollowingStep = utils.invokeEventCallbacks('prev', origStep.onPrev);
  }
}

Out of the changeStepCb closure (L1623) and into the parent changeStep function. The logic in the current version means onNext isn't called until the next steps target can be resolved. Changing the scope gives any onNext functions the opportunity to set up the DOM before trying to attach to the next target.

Can submit a pull request if this seems like an appropriate fix.
