Does this problem occur only in design-time? If so, please describe in details what you do and what is the behavior of the DataAdapter designer. Include MySQLDirect .NET version in your message.

I don't know about lz, but in my situation:

I have the MySQL server explorer open.
Step 1: I drag a table from the server explorer onto the form. This creates a MySQLConnection and MySQLDataAdapter component, and a "SELECT * FROM " query.

Step 2: Right click on MySQLDataAdapter component and select "Configure Data Adpater..."

Step 3: Go to Command Generator tab and click generate commands. An error will occur that states:

The following exception has occured:

ArgumentNullException: Value cannot be null.
Parameter name: oldValue

In my situation, this only occurs in design time. I am using:
Visual Studio .NET 2003 7.1.3088
.NET Framework 1.1.4322 sp1
CoreLab.MySql 2.80.7.0

Hope this helps.

One more thing... This behavior was not occuring with the trial version. It was after I installed the mysqlnet280pro.msi that this started occuring.

Thanks, Andy
