Date: Fri Dec 26 18:31:05 2008 New Revision: 729583 URL: http://svn.apache.org/viewvc?rev=729583&view=rev Log: Improved UEL implementation. FlexibleMapAccessor.java uses the UEL library instead of the home-grown parser. This commit includes the JUEL library taken from CVS - not the 2.1.0 zip file download. It includes the author's modifications to support auto-vivify.
