Bug #28437 Query Builder missing tinytext columns

Description:
The Query Builder of the MySQL Connector/NET Tools for Visual Studio .NET 2005 is missing columns. It shows all columns of a table until it reaches a column declared as tinytext (might also appear with other declarations, I didn't test it). All columns, the one declared as tinytext and the following, are sort of hidden. They are available so far, but not shown in the Query Builder.

This one is critical, because it causes the assistent to create an incomplete typed dataset. No properties are generated for the "hidden" columns. 

How to repeat:
Create a table with several columns. One of them (somewhere in the middle or at the beginning of the table, not at the end) should be declared as "tinytext". Now create a typed dataset within Visual Studio .NET 2005 and add a table adapter. Use the Query Builder to create a query and add the new table to the assistent.

You should see that the tinytext column and all other columns following this one are missing/hidden.
