Continuously update value bug in 10.13


Steve Mills
 

Since we finally were able to move up to 10.13 (printing company, historically slow to change), I've noticed that text fields in views and in cell-based table views now exit editing as soon as any character is entered. Setting a symbolic breakpoint on resignFirstResponder I found that the bindings setting "Continuously update value" is causing this. Has this been fixed in 10.14?

Here's the stack down to where it matters.

#1 0x00007fff4dd1fc9f in -[NSWindow _realMakeFirstResponder:] ()

IIRC, there is another method that you can check, with something like didEndEditing something like that.

I remember having to go through several on iOS to find what I wanted.

I stopped on that breakpoint as well, and it doesn't help other than point out that it is indeed a bug. Changing the bound value should not cause editing to end. I just want to know if it's been fixed since 10.13.
