IOS: multiple modal dialog bug

Hi,

4.0.2 - NSAngular - only on IOS.

I have a flow that require open multiple modal dialog...and I want that the "Done" button on the second Modal Dialog will done the flow and close all modal dialog and send the data for the "page" that opened the modals...something like this:

first Modal Dialog:

public next() {
    const options = {
        viewContainerRef: params.vcRef,
        fullscreen: true
    }
    this._modalService.showModal(SecondModalDialogComponent, options).then(result => {
        this.params.closeCallback(result);
    });
}

second Modal Dialog:

public submit(answer: string) {
    this.params.closeCallback(answer);
}

In Android it works like charm, but in IOS it leaves a blank screen and crash the app...
For workaround I did a double "submit" - every modal close it self and return the data...

Thanks! :)

Confirming that the described scenario is not working as expected on iOS. Tested with latest and next (4.0.0.-2018-05-04-01) and the issue is fully reproducible on iOS.

Steps to reproduce:

• Use this test application
• Open the first modal and then the second modal and tap submit

Result: on iOS, a blank screen shows up instead of the main page

@NickIliev Still lot of issues with modal navigation in the latest next version, it is going to be addressed in the next release - along with other router issues in queue?

@manojdcoder if you have a specific issue that is not a known bug and is not logged please open a new issue and describe it in details so we could test the scenario on our side. We are constantly triaging and prioritizing the issues that are planned for the upcoming releases - you could see the ones that are marked with the upcoming milestone label

@NickIliev Thank you for looking into this. Basically I'm stuck with the same issue you mentioned above. With 6.1 invoking closeCallback from second modal works but when I do routerExtensions.back() again to go back to my previous (non-modal) page it throws exception.

With latest @next version, it doesn't throw any exception and automatically closes the main page after modal is closed.

As I don't see any milestone assigned to this ticket, I wanted to check with you if this is going to addressed along with other router issues those are already in progress.
