When paying a Customer Invoice and information is not entered, iDempiere gives 2 error messages, where as one would be more than sufficient!
iDempiere should only show the error giving valid information to the user. In the attached screen dump, it should only give the error message in the bottom!
this seems to be a problem when more than one error exist!
not reproducible with actual version - payment window is showing several error valid messages, but the "not unique ID" is not being shown.
