WOKeyPathAssociation.m:937: A backsync raises the exception when there is no accessor

[Sergey Golovin-2]

Hi!

There is a chunk of code:
-------------------------------------------------------------------b
 // we do not check the return value, because a set is allowed to
fail
 // (in SOPE ;-) [if there is no accessor, a backsync is just
ignored]
#if 1
     _setValue(self, _value, _component);
#else
 if (!_setValue(self, _value, _component)) {
   [self logWithFormat:@"could not set value %@ component %@",
         _value, _component];
 }
#endif
-------------------------------------------------------------------e

It doesn't work with gnustep (i believe (according to the comment) it
is assumed lF) and raises exception when i want to step in a project:
-------------------------------------------------------------------b
Application Server caught exception:

\"<null>\"; url = \"skyrix://SERVER0/\"; }>"; NSUnknownUserInfoKey =
object; }
-------------------------------------------------------------------e

I'm not along having to deal with the problem:

http://mail.opengroupware.org/pipermail/gnustep-port/2007-November/000116.html

I managed to see the project with the following test case:
-------------------------------------------------------------------b
 // we do not check the return value, because a set is allowed to
fail
 // (in SOPE ;-) [if there is no accessor, a backsync is just
ignored]
#if 1
 NS_DURING {
   _setValue(self, _value, _component);
 }
 NS_HANDLER {
   [self logWithFormat:@"could not set value %@ component %@",
         _value, _component];
 }
 NS_ENDHANDLER;
#else
 if (!_setValue(self, _value, _component)) {
   [self logWithFormat:@"could not set value %@ component %@",
         _value, _component];
 }
#endif
-------------------------------------------------------------------e

Should i go to the bugzilla with that? (Or i'm wrong?)

Ah,

I forgot. When you debug exceptions, always include the GDB backtrace  
(break -raise, bt).

In the specific case we would probably need to add a -
handleQueryForUnboundKey: method.

Its a good idea to document the issue in Bugzilla. (and use that entry  
to attach patches etc)

Thanks,
