I think you want a significant key, perhaps something like
session.unusuallyObtusePropertyKey
in your rules.
if you add this key to D2Ws significant keys, it should always recalculate and you can return something different each call if you like.
ya?

So, somehow, pass the key that returns a value to displayNameForProperty.
Now I don't know what the property key is ahead of time. This comes from data in the session.
It works like a charm to fill in the list, but it is the displayNameForProperty that is confusing me.

100: propertyKey = 'metricA' => displayNameForProperty = "PropertyKey.metricA" [ERDLocalizedAssignment]
Why does that require a custom rule?

Implement your own D2WModel the way you like but make sure you can actually add remove rules to your model. Perhaps you need to define your own methods similar to "addMyRule" or "removeMyRule" etc.
Override application's didFinishLaunching() method and add following code.
@Override public void didFinishLaunching() { super.didFinishLaunching(); D2WModel.setDefaultModel(MyD2WModel.singleton()); }
From this point and onwards I hope you'll be able to use your dynamic rules in d2w components as well. Even if you add rules to by adding / removing rules in your code anywhere using MyD2WModel.singleton().addMyRule(...) will affect the behaviour of d2w components.

I could see how this works. Creating my own on the fly rule model could solve the problem.
But like you said... where?
Have to be session specific.

Start with creating your own D2WModel class since it has methods to update Rules.
public class MyD2WModel extends D2WModel { public MyD2WModel(NSArray<Rule> rules) { super(rules); } public void addMyRule(Rule newRule) { super.addRule(newRule); } }
You can override other methods as needed.
I would suggest implement a singleton pattern for MyD2WModel, and use that whenever you want to infer keys. Whenever you need to access D2WContext with your rules, do something like this:
D2WContext d2wContext = new D2WContext(session); d2wContext._setModel(MyD2WModel.singleton());
Just hack around and see where you need to place it to make it accessible in your templates. May be some guru out there can point out the exact place to hack ;)
Have fun coding!

If that is possible I could create the a rule for each dynamic key.
Do not post admin requests to the list. They will be ignored.
