[Gambas-user] DataControl and "No current Connection" Error

[Mathias Ebermann]

Thanks, Benoit.

But the database connection IS open, that's why I am confused.

DataSource reads the table, and DataBrowser shows the data in the columns I set in properties. So, the connection seems to be
not the problem.
The only things that don't work are the DataControls. They always produce this "No current Connection".

Or am I completely wrong??
I open the database connection in the PUBLIC SUB Form_Open(), first thing. That's the earliest point I can imagine. I also
tried printing out several events, and always the "connected to database" was the first one, everything else came later.

Regards Mathias
