Elektron api exception need more info

@James.Shen

From the top of stack-trace, it seems to be a problem when calling FieldEntry::getReal(). To get more information, you may need try/catch statement, it will print out more information of the actual problem. Below is the method AppClient::decode() that I call fe.getReal() for Integer field and it will raise an exception.

void AppClient::decode( const FieldList& fl )
{
	try{
		while ( fl.forth() )
		{
			const FieldEntry& fe = fl.getEntry();

			cout << "Fid: " << fe.getFieldId() << " Name: " << fe.getName() << " DataType: " << DataType( fe.getLoad().getDataType() ) << " Value: ";

			if ( fe.getCode() == Data::BlankEnum )
				cout << " blank" << endl;
			else
				switch ( fe.getLoadType() )
			{
				case DataType::FieldListEnum :
					cout << ",  contains FieldList." << endl;
					decode( fe.getFieldList() );
					break;
				case DataType::MapEnum :
					cout << ",  contains map." << endl;
					decode( fe.getMap() );
					break;
				case DataType::RefreshMsgEnum :
					cout << ",  contains refresh message." << endl;
					decode( fe.getRefreshMsg() );
					break;
				case DataType::UpdateMsgEnum :
					cout << ",  contains update message." << endl;
					decode( fe.getUpdateMsg() );
					break;
				case DataType::RealEnum :
					cout << fe.getReal().getAsDouble() << endl;
					break;
				case DataType::DateEnum :
					cout << (UInt64)fe.getDate().getDay() << " / " << (UInt64)fe.getDate().getMonth() << " / " << (UInt64)fe.getDate().getYear() << endl;
					break;
				case DataType::TimeEnum :
					cout << (UInt64)fe.getTime().getHour() << ":" << (UInt64)fe.getTime().getMinute() << ":" << (UInt64)fe.getTime().getSecond() << ":" << (UInt64)fe.getTime().getMillisecond() << endl;
					break;
				case DataType::IntEnum :
					// This will raise an exception
					// 	cout << fe.getInt() << endl;
					cout << fe.getReal() << endl;
					break;
				case DataType::UIntEnum :
					cout << fe.getUInt() << endl;
					break;
				case DataType::AsciiEnum :
					cout << fe.getAscii() << endl;
					break;
				case DataType::ErrorEnum :
					cout << fe.getError().getErrorCode() << "( " << fe.getError().getErrorCodeAsString() << " )" << endl;
					break;
				case DataType::EnumEnum :
					cout << fe.getEnum() << endl;
					break;
				default :
					cout << endl;
					break;
			}
		}
	}
	catch (OmmException & e)
	{
		cout << e << endl;
	}
}

From the above code, it produces the following output that contains more details of the exception. In this case, the problem is "Attempt to getReal() while actual entry data type is Int".

Hope this helps.
