>>Hi everybody,

Yes, it does tableupdate.

>(we can answer Yes or No, it would make no difference). Do you know why GetNextModified() function reports a change here while new status code is already saved?

It reports the combo's field as modified. However, even if I answer NO on the question to Save, the change is already saved. In other words, this question should not appear, since the data are indeed saved. I have the same behavior in another simpler form. I interactively change the combobox value, then press the Cancel button that does tablerevert() and then again the question is asked: do you want to save? There is nothing to save.

I may play with different value instead of this. If I remove combo's displayvalue, there would be nothing to save.
If it's not broken, fix it until it is.
