Revision: 160
http://virtualcommons.svn.sourceforge.net/virtualcommons/?rev=160&view=rev
Author: kjonas
Date: 2009-06-12 23:08:38 +0000 (Fri, 12 Jun 2009)
Log Message:
-----------
ForecastComponent.mxml now contains methods save() and load().
These methods are common to all four "styles".
ForecastComponent.mxml also contains value-checking, which only occurs on styles 0 and 2, the two styles that allow data entry.
Style 0 checks for number validity, range, and sum (in columns).
Style 2 checks for number validity and range only.
Error messages are generated and accessible through the public variable errorMessage, but they are not displayed.
