Hilla Lit Binder: bind to map

Is it possible to bind a HashMap to the client-sided binder? In Flow I can use own logic when binding a component to a field, but is also possible in Hilla binder?

The point of Hilla is that you should define DTO object in your @BrowserCallable. This will eliminate need for HashMap.

I am still the specification phase of my data structure and I am not sure where should define properties that are depending on the type of the content of the bean.

I think I need to go for all in one:

public class WStep {

    public enum WStepType {
        PROMPT, CONDITION, TOOL
    }

   private WStepType type;

   // all attributes for all types
   private String text; 
   private String toolName;
   private Object toolConfig;
[...]
}

instead of creating a hierarchy, becausen then I would need to switch the binder for the same bean.

public class WStep {
    public enum WStepType {
        PROMPT, CONDITION, TOOL
    }
   private WStepType type;
}
public class WPromptStep extends WStep {
   private String text;
}
public class WToolStep extends WStep {
   private String toolName;
   private Object toolConfig;
}

I thought I could save the attributes in a map instead of creating multiple classes and binders.

While typing I thought of extracting the config of the class, so I still need to switch binders, but only on the attributes that differs between each types…

public class WStep { // binder 1

    public enum WStepType {
        PROMPT, CONDITION, TOOL
    }

    private String type;
    private WStepConfig config; // binder depending on type
}
