http://issues.apache.org/bugzilla/show_bug.cgi?id=29347 Nested property expansion shouldn't occur but does ------- Additional Comments From [EMAIL PROTECTED] 2004-06-03 10:32 ------- Well, the whole reason for not having nested property expansion is that the parser does not do recursive nesting of brakets, which means that it cannot detect that you are in a nested situation. It it were able to detect the case, then I am almost certain we would allow nested expansion instead forbid it. Looking at your example, you have: ${${a}.${b}} the syntax for a property is: <prop> --> '${' <name>'}' and <name> --> [^}]* which means the above gets interpreted as: '${' "${a" '}' '.' '${' "b" '}' '}' - property "${a" does not exist so it is printed out textually - property "b" does exists, hence it is expanded If we change this to understand recursion, we may as well do nested expansions. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
