Here is my pleasant surprise of the day.
In the past, when a databinding expression failed, it used to be just that: a failure. Anvil wouldn’t tell you what failed or why. I sometimes didn’t even use databinding because it was difficult to debug.
Now there are nice diagnostics telling you which databinding of which control failed.
And you can even click on it and the form appears.
And the control is selected.
And the focus is on the databinding.
