Issue
Numbers with leading zeros calculate incorrectly.

For example, in the Macromedia Firefly FxGrid component, when a user enters a number with a leading zero(s), an incorrect number is posted to the field. If a user enters 011 in a numeric field, then clicks on a different row to post the change, the value put into the field is 9.

Reason
In ActionScript, numbers with leading zeros are interpreted as octal numbers. The octal number system is a positional notation number system. Just as the decimal system uses powers of 10 and the binary system uses powers of 2, the octal system uses power of 8 to determine the value of a number's position.

Solution
The Flash developer should check for a leading zero in numeric entries and convert or trim as appropriate.
