Despite choosing operator "is contained in the a (comma separated) list" it's impossible to imput a comma in the columns if the type is numeric in BRMS web decision table editor

Issue

• In a decision table I have a condition field which is of type "int". Is it possible to configure the field operator as "one of" and put values separated with comma? for example: 1,2,3,4
• In Web Guided Decision Table Editor, I set 'is contained in the a (comma separated) list' as "Operator:". But in case of int field, there is input restriction so I cannot enter comma in a cell. Even if I copy&paste comma separated list to the cell, it will turn into '0'.
