Re: cvs commit: jakarta-commons/jexl/xdocs/reference syntax.xml
Hi Dion, Just one question: How is it possible to support at the same time variables in ant-style and the syntax to access properties (http://jakarta.apache.org/commons/jexl/reference/examples.html#Example%20Expressions)? How do I make the difference between a variable named x.y and a variable x with a getter getY() ?? I had a problem with this in Maven plugins. I had a bug because I used a dotted variable name. Is there a difference between variables names and properties names ?

Just one question: How is it possible to support at the same time variables in ant-style and the syntax to access properties Properties will get precedence. ok. How do I make the difference between a variable named x.y and a variable x with a getter getY() ?? There is none. The property will win. ok it's logic. I had a problem with this in Maven plugins. I had a bug because I used a dotted variable name. Is there a difference between variables names and properties names ? No The problem you had was with the empty function and dotted variables.
