Description

There is an issue with the new supported feature of assigning null-values to velocity variables. The following scenarios illustrate the error. The configuration parameter "directive.set.null.allowed" must be set to "true".

Scenario 1 (correct behaviour outside macro):

#set ($test = "test")
$test
#set ($test = $null)
$test

yields to the output:

test
$test

Scenario 2 (erroneous behaviour using macro):

#macro (test)
#set ($test = "test")
$test
#set ($test = $null)
$test
#end

#test()

yields to the output:

test
test

and the varibale test has not been resetted to null which is the error.
