[Radiant] Problem with tag.locals

[Adam Salter]

Keith,

This didn't work.

I'm going to work around it by doing:
<r:anothertag id='1' />
<r:yetanothertag id='1' />

for the moment... but it's not going to work in the long run... is  
there a way to force/pass or create your own variables?

e.g
tag "mytag" do |tag|
    if tag.attr["id"]
      tag.locals.gallery = Gallery.find_by_id tag.attr["id"]
    tag.expand { "id" => "1"}
end

...or...

tag "mytag" do |tag|
    if tag.attr["id"]
      tag.locals.my_gallery = Gallery.find_by_id tag.attr["id"]
    tag.expand
end

...or...

tag "mytag" do |tag|
    if tag.attr["id"]
      tag.globals.gallery = Gallery.find_by_id tag.attr["id"]
    tag.expand
end

Thanks in advance,
-Adam
