Mixin Order

[Geoffrey Wiseman <ge...@gmail.com>]

Is there a way to control the order of mixins?  I've declared them in a
particular order, and it looks like Tapestry's applying them in reverse
order -- I could reverse the order of declaration, but I was just wondering
whether or not there's any guarantees here, or if I'm essentially relying on
something I shouldn't be ...

Hi Geof, the only ordering tapestry does is to ensure that mixins with  
"@MixinAfter" are applied correctly.
Otherwise, I the order is basically a crapshoot.  I had always assumed  
that mixins would be applied in the order specified, but from a recent  
perusal of mixin-related code, I've found that's not so.  But there  
are difficulties with this because the mixins to apply can come from  
multiple sources: the t:mixins element in the template, the @Mixins  
annotation on a @Component instance, or the @Mixin annotation within a  
component class ("implementation mixins").  So the question for  
ordering becomes how to properly order the disparate sources of  
mixins.  For example, you could order as:
   template (in order specified), @Mixins annotation (in order  
specified in the annotation), @Mixin classes (in order specified  
within the component class).
Or maybe:
   @Mixins, template, @Mixin

Or... :)

Please open a jira for proper ordering of mixins; I'll be interested  
to see opinions on what is the "right" mixin ordering.
