Problems with the upgrade process about angular2-indexeddb HOT 3 CLOSED

@GAlexMES,

You are trying to run two async operations in parallel and ending up with that error.
In order to correct your code you will have to run the second open in the then function of the first open call.

this.database.openDatabase(3, 
    (evt) => {
        console.log("version 3");
        this.database.openDatabase(2, ...)
    }(error) => {
      console.log(error);
    }
)

Okay, I tried it. It works, when I already have a version 3 database in my browser.
But when I have a version 0, 1 or 2 it failes, when I try to open it in an older version. So in your example "version 3" would be printed to the console and then I got an error.

Thanks for your help.

I resolved it with just opening it once with the current version and then doing a switch on the evt.oldVersion.

  this.database.openDatabase(3, (evt) => {
      switch (evt.oldVersion) {
        case 0: this.version0(evt);
        case 1: this.version1(evt);
        case 2: this.version2(evt);
        case 3: this.version3(evt);
      }

It is a bit dirty but It works for now.
