Claude Brisson resolved VELOCITY-944.
-------------------------------------
Fix Version/s: 2.4.1
Resolution: Fixed
I understand why I could not reproduce it: it only happens when the topmost
template is directly evaluated, not loaded via a resource loader.
It is now fixed.
> Macros in string literals are not resolved when local_scope is enabled

> Key: VELOCITY-944
> URL: https://issues.apache.org/jira/browse/VELOCITY-944
> Project: Velocity
> Issue Type: Bug
> Components: Engine
> Affects Versions: 2.0, 2.1, 2.2, 2.3
> Reporter: Jakub Isakow
> Assignee: Claude Brisson
> Priority: Critical
> Fix For: 2.4.1

> Attachments: VelocityTest.java, pom.xml

> When local scope is enabled with
> {noformat}
> velocimacro.inline.local_scope=true
> {noformat}
> a template that is using a macro in string literal is not working correctly.
> Example template:
> {code}
> #macro( m $v )
> <span>$v</span>
> #end
> #set($v = "#m('bar')")
> $v
> #m( 'foo' )
> {code}
> Actual result:
> {code}
> #m('bar')
> <span>foo</span>
> {code}
> Expected result:
> {code}
> <span>bar</span>
> <span>foo</span>
> {code}
> The example template is working correctly for velocity 1.7.
> After debugging a bit I think the problem might be caused by creating a new
> Template instance in
> [org.apache.velocity.runtime.parser.node.ASTStringLiteral#init|https://github.com/apache/velocity-engine/blob/2.3/velocity-engine-core/src/main/java/org/apache/velocity/runtime/parser/node/ASTStringLiteral.java#L145-L149].
> Because of that, when macro is being resolved, there is no macro instance
> available in local scope (template instance) and it is rendered as string.
> Locally I was able to make it work by using {{this.template}} when
> {{context.getCurrentResource()}} returns {{null}}.
