Re: treemaps

First thing, stop saying "treemaps" and instead read your error
messages.. the error message is indicating that you are calling a method
entitled "font_size" on an object that doesn't support it. If you trace
your call stack you will find the culprit and tackle it from there. As
for acts_as_treemap, check the docs that shipped with the plugin.

You were right, I have found this method and several other methos that
call this one. Finnally I have been able to fix it and show the treemap.

Thanks for your comments

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>

`html_treemap'

`_run_erb_47app47views47sourceforge_map47index46html46erb'

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

Regards

Peter
