java - Restrict report parameter to a certain length -


in birt report created report parameter entering "year" value. want restrict 4 digits on input field. how can that? user should type 4 digit in field. configuration or script available achieve this?

you can't restrict length of textbox-entered value in birt.

you could set parameter display type list box , specify available values year, either static list of values entered in edit parameter dialog or dynamic set of values retrieved dataset.
