bpl_1
//----------------------------------------------
   calls method located in bpl_2
//----------------------------------------------

bpl_2
//--------------------------------------------------------------------------
------------
TMyDataSet *a_MyDataSet = dynamic_cast<TMyDataSet *>(DataSource->DataSet);
this gives a NULL.
//--------------------------------------------------------------------------
--------------

But if i cast
TMyBaseDataSet *a_TMyBaseDataSet = dynamic_cast<TMyBaseDataSet
*>(DataSource->DataSet);
it works OK.

TMyBaseDataSet and TMyDataSet
implemented in the  bpl_2

The RegisterClass in both bpl does not give an effect. It works the same
way.
the main executable compiled with runtime packages.
