No, there isn't as far as I know. Checking isNumber is rather easy because you can decide it by looking at a single character. A format like date you have to parse.

The scenario I'm looking at is making sure a value in a Seaside control has been entered correctly.

You can try to parse the date | date | [ date := DateAndTime fromString: aMightBeADate ] on: Error do: [ :err | ]. After that your date test is isNil. Either you get the parsed date or it is nil if it couldn't parse a date. Norbert

Oops, missed a line :-( | amIaDate | amIaDate := '30 Feb 2010'.
