null-values cannot be set in macros
-----------------------------------
Key: VELOCITY-594
URL:
https://issues.apache.org/jira/browse/VELOCITY-594 Project: Velocity
Issue Type: Bug
Affects Versions: 1.5
Environment: Windows XP SP2
Reporter: jukefox
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 <i>directive.set.null.allowed</i> must be set to <i>true</i>.
Scenario 1 (correct behaviour outside macro):
<pre>
#set ($test = "test")
$test
#set ($test = $null)
$test
</pre>
yields to the output:
<pre>
test
$NULL
</pre>
Scenario 2 (erroneous behaviour using macro):
<pre>
#macro (test)
#set ($test = "test")
$test
#set ($test = $null)
$test
#end
#test()
</pre>
yields to the output:
<pre>
test
test
</pre>
and the varibale test has not been resetted to null which is the error.
