How to integrate TinyMCE in Streamline?

Question

I try to integrate the Tinymce wysiwyg-editor into my adminpage whitch i create with streamlined framework.

I wan to reset all textareas with this line:

<%= tinymce_tag('comment[body]', 'Your comment goes here ...') %>

but where i can find in streamline part to make this available?

Can i edit that in this file? -> ROOT_PATH/streamlined/sport.ui.rb there i have:

module SportAdditions

end Sport.class_eval { include SportAdditions }

Streamlined.ui_for(Sport) do user_columns :name, :history edit_columns :name, :history { } # here i wana replace the default textarea with tinymce_tag('...', '...') is that possible?

end
