jukefox updated VELOCITY-594:
-----------------------------
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):
{code:title=Bar.java|borderStyle=solid}
#set ($test = "test")
$test
#set ($test = $null)
$test
{code}
yields to the output:
{code|borderStyle=solid}
test
$NULL
{code}
Scenario 2 (erroneous behaviour using macro):
{code|borderStyle=solid}
#macro (test)
#set ($test = "test")
$test
#set ($test = $null)
$test
#end
#test()
{code}
yields to the output:
{code|borderStyle=solid}
test
test
{code}
and the varibale test has not been resetted to null which is the error.
