为什么升级后 bpl 会出现 Error Loading a resource string？

Question

We have a bpl that has some resource (.rc) files which has strings in it. It is defined via STRINGTABLE and loaded via a LoadStr() call. The project was in version 10.1 Berlin. We upgraded to the latest 11.1 Alexandria and now the call returns NULL . So to test I added the line at the main

extern "C" int _libmain(unsigned long reason)
{
  String str = LoadStr(231); **// Works**
  return 1;
}

but the existing code below does not work.

**.h**
PACKAGE String __fastcall GetValueSetDesc(int ACount);

**.cpp**
String __fastcall GetValueSetDesc(int ACount)
{
  String ValueDesc = LoadStr(ACount); **// Does not work, retuns NULL**
  return ValueDesc;
}

I tried creating the project from scratch (and adding files to it). Any one has experienced this issue or know what to try?

The problem was with DevExpress components. The call was from a DevExpress change event. A call from a non DevExpress component worked fine. The way I solved this is to re-create the cbproj from scratch and add the files, settings etc (in the exe, the bpl seems fine). Man, DevExpress gave me a lot of grief this time around when we upgraded!
