Error opening checkout when using Purchase as a Fragment instead of an Activity

[ohsnapitscolin]

Hey all,

I filed an issue in the React Native demo repo as well, but essentially I'm trying to create a Purchase Fragment using the example code here. The problem is the app crashes with the following error when trying to open checkout:

E/DevLauncher: DevLauncher tries to handle uncaught exception.

It looks like in the Fragment demo code, we use the childFragmentManager instead of the supportFragmentManager that's used in this activity-based demo (which I believe is necessary, since we're creating a PurchaseFragment, not a PurchaseActivity).

val factory = TMPurchaseFragmentFactory(
    tmPurchaseNavigationListener = PurchaseNavigationListener {
        childFragmentManager.popBackStack()
    }
).apply {
    childFragmentManager.fragmentFactory = this
}

The problem seems to be the following lines in com.ticketmaster.purchase.internal.ui.ticket.PurchaseFragment$setupNavigationObserver$1 (which I when I dug into them look something like this):

PurchaseFragment var3 = this.this$0;
int var5 = false;
FragmentFactory var6 = var3.requireActivity().getSupportFragmentManager().getFragmentFactory();
TMPurchaseFragmentFactory fragmentFactory = var6 instanceof TMPurchaseFragmentFactory ? (TMPurchaseFragmentFactory)var6 : null;
if (fragmentFactory == null) {
   throw new TMFragmentFactoryNotFound("Please use TMPurchaseFragmentFactory");
}

In this case the requireActivity().getSupportFragmentManager().getFragmentFactory() is not a TMPurchaseFragmentFactory, because the factory was set on the childFragmentManager instead.

Is it possible to support the Fragment use case? Or do I need to use a separate activity entirely? Is is possible to pull the childrenFragmentManager from the PurchaseFragment in the code above?

@ohsnapitscolin i found a solution for this, i explicitly set the parents fragment factory along with the child fragment. https://github.com/ticketmaster/ReactNative-TicketmasterDemoIntegration/pull/10

Closing this since there's a discussion happening on the issue mentioned above.
