Cetin, I tried with Private DataSession and it worked, but using Private DataSession I went into other problems, so I tried in anoher way :
Before I call the second form I set the rowsource properties of the combos to '', then I set them to the proper Rowsource after the line of code in which I call the form (the form is Modal)
Thank you for your advice
Alessio
