Angular teams lose track of errors in complex forms
Angular frontend developers building large, nested forms can struggle to find and present validation errors, especially when invalid fields are inside tabs, dynamic arrays, or custom controls. The cited workarounds include recursively walking control trees, manually checking tabs, and adding awkward template hacks. The reports are from 2016–2018, so whether the pain remains widespread needs validation before building.

I'd expect a lot of people working with complex forms are creating workarounds for this like we had to, effectively creating methods that recursively traverse the tree of controls looking at each control's errors objects manually in order to create an aggregate object
But in my case, the tabs are actually "dynamic", in the sense it's placed within a FormArray of unknown length, and there can even be tabs of tabs, or FormArray of FormArray. So at the end, it's just one massive form where I need to have a "summary" of all errors
