@Paulo : please provide detailed steps on how to reproduce the behaviour you see, and additionally a test ODB file Setting to NEEDINFO until the requested information is provided.
Have tried this: Listbox in a tablecontrol, based on a query like SELECT NAME, ID FROM TABLE Set the bound field to '2', which is a wrong value. Saved the form, opened it for input. No value is shown, but also no crash. Couldn't confirm without any more information.
No feedback after 4 months whereas there wasn't even a description. Paulo: Don't hesitate to reopen this tracker one if you respond Alex's comment.
