I found a difference between Delphi's SetPropValue function with its counterpart in FPC. In Delphi, this function is case insensitive, while in fpc it is case sensitive.
Am I correct?

The property name comparison (ending up in GetPropInfo(TypeInfo: PTypeInfo; const PropName: string),
rtl/objpas/typinfo.pp line 571) is done case-insensitive, unless there is a bug somewhere.
Can you provide code snippet illustrating the difference?

I studied a little deeper and the problem is (according to FPC 2.2.2 manual) that SetPropValue doesn't work because Variants are not implemented yet.
The solution was easy, I used SetStrProp instead of SetPropValue. In my program all published properties were strings.
Can you confirm if it is implemented in newer versions?

Hmm..I thought that variants were supported long time ago but my memory is bad.
Are you sure about that ?

I think it's more probable that the documentation wasn't updated then that Variants aren't supported.
