maybe someone will give me idea how can i overcome this problem.

i have TDataSetActions and TMyDataSet  implemented in one package.(package1)

the other modules use this package for design purpose.
meaning, i develop forms with my TDataSetActions and TMyDataSet

the TDataSetActions use TMyDataSet descendant inside package1,
when user fires event for dataset, i need to cast a DataSet to TMyDataSet

TMyDataSet *a_MyDataSet = dynamic_cast<TMyDataSet *>(DataSource->DataSet)

and it this gives a NULL.
thus DataSet->ClassName() ==  "TMyDataSet"


some ideas will be appreciated.
please help.
