Problem is simple:

when i trying to add g modifier to regexp

i getting this error message at element
Item preprocessing step #2 failed: cannot perform regular expression match on value "47590;3172;0" of type "string": pattern does not match

regexp: /(\d+)/g
String: "47590;3172;0"

When i delete "g modifier", regexp working fine.
