This issue is a duplicate of http://issues.apache.org/jira/browse/VELOCITY-71
I'm resolving this one to give preference to the earlier report.
> Use of Velocimacro forward reference and/or recursion causes error messages
> ---------------------------------------------------------------------------
>
> Key: VELOCITY-108
> URL: http://issues.apache.org/jira/browse/VELOCITY-108
> Project: Velocity
> Type: Bug
> Components: Source
> Versions: 1.3-rc1
> Environment: Operating System: All
> Platform: All
> Reporter: Daniel Rall
> Fix For: 1.5
> Attachments: TestVelocity.java
>
> I've confirmed that both forward referenced and recursed Velocimacros cause
> error messages in 1.3-rc1 and 1.3.1-rc2 (I assume the intervening versions are
> affected as well). I have not (yet) tested 1.4-dev.
> The error message currently spouted by
> org.apache.velocity.runtime.directive.VelocimacroProxy does not differentiate
> between forward referencing and recursion (it is a very similar problem), and
> is
> not representitive of the problem. It goes as follows:
> 2002-10-14 16:03:49,562 - VM #linkIf: error : too few arguments to macro.
> Wanted 3 got 0
> This issue can be reproduced through either of the following setups:
> a) Use the #linkIf macro in your VM_global_library.vm, then define it later on
> in the file.
> b) Define a #linkIf macro which calls itself recursively.
> The expected behavior is that Velocity will either provide a more accurate
> description of what it wants from the user, or allow forward referencing and
> recursion without error messages. If not already in use, perhaps a multi-pass
> approach to dealing with Velocimacro libraries should be put in place to
> implement this.
