xpages - Modify edit box data display type error message -

i have edit box in xpage , i've set data display type number. have error message component can display error if insert other char not number. message:

this field not valid integer

so question is- there way modify message can display whatever want in message? or shouldn't bother , achieve functionality in other way?

the message handled in-built number converter, need add own converter change message , handle conversion between number required business logic , string required browser.
