Have you done more tests on this? Who is raising the exception, the text field, the control or the cell? Or will I have to do these tests myself?
In [NSCell-setStringValue:] we have this code:
if (aString == nil)
@"Attempt to use nil as string value");
Did this get triggered in your case? And if not, why not? If you are interested in Mac compatibility you could run your code with the option --GNU-Debug=MacOSXCompatibility
I was running without that flag... so is it expected that GNUstep behaves slightly different? IN case, I'm fine, else I will prepare a testcase as you request. It won't be difficult. IN the meanwhile I fixed the application where this was happening.
