MySQL Bugs: #12551: Error at the ConnectionString

Bug #12551	Error at the ConnectionString - Property
Submitted:	12 Aug 2005 14:36	Modified:	30 Aug 2005 6:22
Reporter:	Stefan Krejci
Status:	Closed
Category:	Connector/Net	Severity:	S2 (Serious)
Version:	MySQL 5	OS:	Microsoft Windows (Win2000)

Description:
At Delphi 2005 Prof: 

File --> New --> Windows Forms --> dragging "MySqlConnection" on Form --> Property
"ConnectionString" contains "Der Objektverweis wurde nicht auf eine Objektinstanz
festgelegt." [German version of Delphi2005]
There's no possibility to set ConnectionString to a real connection string as proposed in
some examples. 

When not using the MySqlConnection as Component but only at the source code, as e.g.:

var   msc : MySqlConnection;
  msc:=MySqlConnection.Create('...')

then the error doesn't occur!

How to repeat:
The error occurs every time using the MySqlConnection - Class

I was able to reproduce the bug on Delphi 8. Probably it is Deplhi 2005.
Property "ConnectionString" contains "Object reference not set to an instance of an
object."
I tested on Microsoft Visual C# .NET - there is same result.

.Net c# 2003 - Windows Server 2003 as well, same steps as above.
