> Key: VELOCITY-926
> URL: https://issues.apache.org/jira/browse/VELOCITY-926
> Project: Velocity
> Issue Type: Bug
> Components: Engine
> Affects Versions: 2.0, 2.1
> Reporter: Claude Brisson
> Assignee: Claude Brisson
> Priority: Major
> Fix For: 2.2
>
>
> Consider the following example:
> {code}
> #macro( test $foo $bar )
> $foo $bar
> #end
> #set($foo = 'foo')
> #set($bar = 'bar')
> #test( $bar, $foo )
> {code}
> The expected result would be "{{bar foo}}", but since 2.0 we get the incorrect result "{{bar bar}}", as if the first inner {{$foo}} macro argument was overwritting the second argument evaluation.
