The root cause of this issue is the improper computation of the `accountBalance` expression role in the accounts model. Its value depends on another model (`filteredBalancesModel`) and by the time the expression role gets computed the proper `balance ` is not ready in the `filteredBalancesModel`.
This is a quick fix, but maybe the real fix should be restructuring the adapter and the model dependencies. I'd look out for any `ModelUtils` usage and replace it with a declarative approach if possible.
