When passing literals other than strings to macro calls, setting new values the
formal parameters does not propagate the changes outside the local scope
--------------------------------------------------------------------------------------------------------------------------------------------------------
Key: VELOCITY-683
URL: https://issues.apache.org/jira/browse/VELOCITY-683
Project: Velocity
Issue Type: Bug
Components: Engine
Affects Versions: 1.6.1, 1.6, 1.5
Reporter: Sergiu Dumitriu
Priority: Minor
With this macro definition:
#macro(setValueToEmpty $value)
#set($value = '')
#end
While the following works well:
#set($value = 'abc')
#setValueToEmpty('abc') => $value == ''
this fails:
#set($value = 'abc')
#setValueToEmpty(3) => $value == 'abc'
This is caused by the fact that in
org.apache.velocity.context.ProxyVMContext#addVMProxyArg if the parameter is a
constant (which somehow doesn't include strings), then a local variable is
created with the node's value as its value. For string literals, the actual
node is placed in the proxy map, which allows setting a new value for it.
