Hi Javi,

I have also the missing method "font_size" problem. I exactly used the 
Sourceforge treemap database and the coding from the tutorial.
Plugin installation for acts_as_tree and acts_as_treemap worked.

I'm on Ruby 1.8.6 and Rails 2.0.2.

The trace gives a beginner like me no indication what's wrong:

undefined method `font_size' for #<SourceforgeNode:0x35da8c4>
...
C:/ruby/lib/ruby/gems/1.8/gems/activerecord-2.0.2/lib/active_record/attribute_methods.rb:205:in

`html_treemap'
app/views/sourceforge_map/index.html.erb:1:in 
`_run_erb_47app47views47sourceforge_map47index46html46erb'

Could you give me an advice how you found the related spot ?

Regards

Peter
