#199 Problem with TOvcTcComboBox in Delphi 2010

[SpazioInformatico]

I’m working with Delphi 2010 and I’ve got a problem with the Orpheus’ Component TOvcTcComboBox.
In my project there is an OvcDbTable with some columns. One of this is hooked to a component TOvcTcComboBox.
I populate theOvcDbTable at the creation of the form and at the same time, I populate the combo from the code with a procedure.
When I open this project, i get an error of Access Violation.
I can’t understand what is the problem.
The version of this component is the last one (4.08).
