This is a bug of amrita 1.8.0 and I fixed it. The next release will be
OK with this code.

And amrita V2.0 provides a new feature called 'Amulet'. With Amulet,
you can do the same thing keeping clean seperation of model and view.

----------------------------------------------------------
require 'amrita/template'
include Amrita

t = TemplateText.new <<END
<table>
  <tr id=row class="odd">
    <td><a id="lang">dummy data</a></td>
  </tr>
  <tr id=row2 class="even">
    <td><a id="lang">dummy data</a></td>
  </tr>
</table>
END

t.define_amulet(:row, :row2)

links = [
  t[:row][{:lang=>a(:href=>'http://www.ruby-lang.org'){"ruby"} }],
  t[:row2][{:lang=>a(:href=>'http://www.python.org')   {"python"} }],
  t[:row][{:lang=>a(:href=>'http://www.perl.org')     {"perl"}}],
]

t.expand(STDOUT, :row=>links)
----------------------------------------------------------

This code makes same result and you can adjust the color or any
appearance of each row touching only the template without running
or modifying the code.

I wrote some pages to amrita-Wiki from this thread. 

   http://www.walrus-ruby.org/aswiki/aswiki.cgi?c=v;p=EvenOddRow
   http://www.walrus-ruby.org/aswiki/aswiki.cgi?c=v;p=Amulet

For detail of Amulet, see them.

Thank you for a useful question.
