In some forms some element names disappear.
I have a form named “fm_sv_control” containing 20 fields and 4 labels/buttons. Fields are named duplabi01, duplabi02 aso, the labels are named sv_control_label and sv_control_txt and the buttons names are sv_control_ok and sv_control_canc.
All field names are visible, while all label/button names are not visible in the elements list. I tried to change them, make a new form, but nothing happens.
However, if I rename the labels and the buttons control_label, control_canc (without the “sv_”), these elements reappear in the elements list.
Anyone could tell me why this behaviour?
