Really? Great to here :-)

OK, "ivar KVC" is not supported, only method KVC. So we should add 
that, seems to be important.

Currently WOKeyPathAssociation has an optimized and caching version of 
KVC which is much faster than the generic KVC API (eg avoids the 
creation of intermediate number objects when you bind an "int" to an 
"int").

It should be trivial to use the KVC implementation provided by 
gstep-base by doing such a category (probably mirrors what gstep-web is 
doing):
---snip---
@implementation WOKeyPathAssociation(UseFoundationKVC)
- (void)setValue:(id)_value inComponent:(WOComponent *)_component {
  [_component takeValue:_value forKeyPath:self->keyPath];
}
- (id)valueInComponent:(WOComponent *)_component {
  return [_component valueForKeyPath:self->keyPath];
}

...
- (int)intValueInComponent:(WOComponent *)_component {
  return [[self valueInComponent:_component] intValue];
}
... etc
@end
---snap---

Hm. I might add this as an compatibility option to SOPE, no big deal, 
stay tuned ;-)

It will be a significantly slower, but is going to provide all the KVC 
features available in gstep-base.
