EAccessViolation error when trying to LogOn

[Pavel Rodionov]

Hi, i'm using doa in such way:
i have MainApp which load packages(bpl) #testPack.bpl...and in this package EAccessViolation error occurs, i've detected that it take place in following block:

try {
           connection->LogOn();

    }
    catch (const EOracleError& e) {
        throw ConnectionException("OracleDataAccessor::connect()",
            e.Message.c_str()+std::string("...")+IntToStr(e.ErrorCode).c_str());
    }
    catch (const Exception& e) {
        throw ConnectionException("OracleDataAccessor::connect()",
            e.Message.c_str());
    }

error is catching in second block with message:
"Access Violation at address bla-bla-bla in module doa40c6.bpl"
