error in extended search in modal windows

[darkdragon]

scenario:

• table begining with _ (_ImportAmounts)
• the table allows for importing excel files
• there is one field (string) which is set-up as Select which uses a lookup table; the lookup is set as modal dialog.

worked perfectly inANM2019
after conversion to ANM2021, I get this error Cannot perform runtime binding on a null reference, after trying to search in the modal (modal never shows)

renamed the table to remove the "_" prefix and now it's OK
