In UniDAC 2.7 I'm having a problem adding data toa virtual table in design time. After this procedure I can't compile anymore. The error message is: Project XXX raised exception class EclassNotFound with message 'Class TintegerField not found'

We cannot reproduce the problem. Please specify your version of Delphi or C++Builder.

I'm using BDS 2007 and with UNidac 2.5 version I had the same problem. Reproduce its simple: create fields in design time and add data in design time too. When I try to compile, it's not possible cause the error.

Have you added "DB" in your uses clause?

There is a known problem with VirtualTable. If you create fields at design-time, and then add data, fields are dropped from the *.pas file. You should recreate fields after you add data to avoid the problem.

Yes, I did it. But the error persists.

Please check that your *.pas file contains the declaration for TIntegerField objects (inside declaration of the form class).

Yes the fields are declared.

Please specify whether the error occurs during compilation or when you run the application (press Ctrl+F9 and see if an error will occur).

We could not reproduce the problem. Please send to unidac*devart*com a complete small sample that demonstrates the problem.
