Force Decimal Regex

Question

I'm looking for a regex or a way to format the NumberValidator so that only decimal places are allowed.

The domain="real" allows you to put integer values, but I need to force the user to but in 2.0 if they want an integer.

This is because they pass through a Castor mapping file, it complains if it gets an integer when it expects a decimal.

I dont want to restrict the number of decimal places, just insist that there must be a point, and a number after it.

Any help would be much appreciated.

I don't know Flex, but if I undrestand correctly, you're probably looking for something like /^-?\d+\.\d+$/. Or /^-?\d*\.\d+$/ if .1 is valid.
