How do I check a text for holding a date value?
isNumber is handy for numbers. Is there anything like that?

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.
