Thanks for answer Helen,

But, I want to change all component IBX to IBO, but when I open the Form,
with contained IBX Component, the error appears, and the form isn't create,
and I don't now how to change the component...

The only method is I create a new Form? with new component IBO?

Thanks for All,

Fellipe H.
