FastReport error di Delphi XE2

The FastReport Designer cannot find classes and the IDE wants to remove 
FastReport Components from forms.

Pernah saya menjumpai teman yang menggunakan Delphi XE2 Fast Report sebagai reportnya mempunyai error sebagai berikut

This error causes by GroupDescendentsWith(TfrxReport, TControl); code.
This code hides TfrxReport from FierMonkey and for some reason 
"FindClass" function can't find for TfrxReport class when you're loading 
report(only in IDE).
If you can't load report or get similar error with "Couldn't find 
TfrxReport" message
