Hello, thanks for using Ionic. Would you mind posting a repo we could use to reproduce this issue?

I have similar problem! We have a two level navigation.
If we navigate to /main/configure, this means first ion-nav is loading man and second ion-nav is loading configure page. The problem is, if we navigate only to main, we will in the constructor load the default Page which is Dashboard.
So this would be /main/dashboard

The problem is if we load directly /main/configure the construcor first will load Dashboard and then the framework as wanted loads ConfigurePage.

So for me is not clear if this is a lazy loading and IonicPage bug or there is something we don't know. There is no now to check in construcor which is the requested page or url. Or if it exists, itbis not documented!
