</div>

for this text\_area:  
\<%= text\_area( “user”, “tasks”, :cols=\>30, :rows=\>10) %\>

default value would be to set  
@user.tasks = text\_fields[:user\_tasks]  
in your controller.

hope this is what you were looking for.

well, you can do that like i posted before.  
only thing you have to add is maybe an ajax-call to reload that  
textarea.  
once you figured how to put default values into that text-area, and  
how to replace\_html with ajax, this should be no problem. try it.
