[regression] Changes on the macro parameters are not persisted outside the
macro call
-------------------------------------------------------------------------------------
Key: VELOCITY-681
URL: https://issues.apache.org/jira/browse/VELOCITY-681
Project: Velocity
Issue Type: Bug
Components: Engine
Affects Versions: 1.6.1
Reporter: Sergiu Dumitriu
Priority: Critical
Fix For: 1.6.2, 1.7
The fix for VELOCITY-615 was too radical, since it completely disables #setting
new values to the formal arguments. A minimalistic example that used to work up
until 1.6 is:
{noformat}
#macro(myMacro $result)
#set($result = 'some value')
#end
#myMacro($x)
$x
{/noformat}
which prints $x (as an undefined variable).
