Velocity 1.5 raises errors for templates that ran in 1.4.
---------------------------------------------------------
Key: VELOCITY-528
URL: https://issues.apache.org/jira/browse/VELOCITY-528
Project: Velocity
Issue Type: Bug
Affects Versions: 1.5
Environment: Windows XP SP2, JDK 1.5
Reporter: Michael Giroux
Migrated from Velocity 1.4 to 1.5. I have several templates that ran in 1.4
and now fail in 1.5. I raised this in the mailing list and Nathan Bubna asked
me to file a bug.
This is probably an error in my template, but 1.4 allowed it to execute without
complaints. I might have been lucky that nothing bad happened.
Existing templates contain the following.
public $method.returnType $method.name(
#foreach($param in $parameters)
...
#end
The intent here is to emit a java method signature for a method named
$method.name . This works in 1.4.
In Velocity 1.5, an error is thrown indicating that the #foreach is unexpected.
Velocity 1.5 is expecting a method parameter becuase the variable name is
terminated by an open paren.
I fixed the problem by adding curly braces to the template as follows:
public $method.returnType ${method.name}(
#foreach($param in $parameters)
...
#end
This is probably a bug in 1.4, and poor coding practice in my template, but
given the fact that it did work and now doesn't, there should be some mention
of this "improvement" in the 1.5 release notes.
