There are couple of mistakes in your code. This should help you (Please compare it side by side to get the idea of what was wrong in your code). Note: you have not defined setAnswerButton (or at least not mentioned it in the question, so please do make sure it is implemented)

You can do it with:

If you use param['objective'] = 'multi:prob' instead of param['objective'] = 'multi:softmax', the result of the classifier is a of probabilities for each class.

1. Creating a ViewModel instance and using the WindowManager interface is not against MVVM. You should be fine with that.

2. I am not familiar with the Caliburn Micro Framework. But what about this:

   • Hold the artikelliste as a property in ViewModel2.
   • Hold an instance of ViewModel2 as a property in ViewModel1. You pass that instance when invoking the WindowManager.ShowWindow method.
   • Then, when the artikelliste has been filled, you can invoke an event on ViewModel2, for example ArtikelListeUpdated. ViewModel1 listens to that event and reacts to it if necessary. You even don't need the event in case you don't have to react to it immediately.

Edit: Example for the last step:

When using | you should wrap that group in parentheses.

You should update both Invoice and Amount declarations...

It helps to break down the problem into steps.

In the code below, I've done this in 3 steps:

1. Extract all of the features into an array
2. Remove any duplicate features
3. Filter the features so that we're only left with the common ones.

In the code below, I've only included the first 2 rooms from your data. You should be able to click Run code snippet to see the result.

Three of your elements have incorrect permission names. There are no Android SDK permissions that begin with android.permissions (note the s on the end). So, for example, you need to change android.permissions.ACCESS_FINE_LOCATION to android.permission.ACCESS_FINE_LOCATION. You cannot request a runtime permission if the element is missing or invalid.
