Of cource I fix this bug in may application using [txt setStringValue: [arr description]], but I thing, crashing object on invalid input is not good.

I just tested and both of these lines work perfectly:

[txt setStringValue: [arr description]];
[txt setObjectValue: arr];

I will decline this bug report. What is strange is that GNUstep is not able to report properly what is going wrong. When trying to show an alert panel with the doesNotRecognizeSelector: message the text cell falls over as the arguments cannot be handled as text. This leads to a very strange output. But this is an unrelated issue:

Array2TxtFld.app/Array2TxtFld: Uncaught exception NSGenericException, reason: Glyph generation was triggered for a layout manager while the text storage it was attached to had unprocessed editing. This is not allowed. Glyph generation may be triggered only at points where calls to -beginEditing and -endEditing are balanced.

I'm not sure if we should follow OpenStep here. The method setStringValue: is clearly defined to take an NSString parameter. Putting anything else in there is wrong.

If you want to get this specific string displayed, why don't you use description on the array or set the array as the object value via setObjectValue:? If GNUstep has a problem with any of these two ways to do it, I am willing to fix that. But adding the requested feature doesn't look like a good idea.

Sorry I forgot to write a version of GNUstep.
There it is:

Tue 10 Jul 2007 09:13:37 AM UTC, original submission:

I have an OpenStep application ported to GNUstep. During port I found a bug in setStringValue: method of NSTextField.

id arr = [[NSArray alloc] initWithObjects: @"a", @"b", nil];
id txt = [[NSTextField alloc] initWithFrame: NSMakeRect(5, 37, 200, 28)];

[txt setStringValue: arr];

This crash on NSException, but in OpenStep it shows "(a, b)" string in NSTextField. I have attached some example.
