I have a table that lists domain names, with a form next to it to add  
new domains.

I have AJAXified this so that new domains are immediately added as table  
rows. This works fine in Firefox 1.5/Win, but not in IE6/Win. Domains  
are added into the database, but the HTML table is not updated unless  
you reload the page.

Some googling tells me there are issues with e.g. link\_to\_remote  
updating tables in IE (I tried updating a div and that worked fine), so  
I’m simply asking if anyone knows of a decent solution, other than going  
non-AJAX, dropping IE support or using something other than a table.

Also, has anyone written code to get validations with link\_to\_remote? So  
if someone attempts to add a non-valid domain, you would get some sort  
of readable error message.

Some of my code:

View:

\<%= form\_remote\_tag(  
:url =\> { :action =\> ‘create’ },  
:update =\> “items”,  
:position =\> :bottom,  
:complete =\> ‘focus\_field()’) %\>

Controller:

def create  
@domain = Domain.new(params[:domain])  
if @domain.save  
render(:partial =\> ‘domain’, :object =\> @domain, :layout =\> false)  
else  
#FIXME: No decent error handling yet - try adding duplicate  
domains  
render :action =\> ‘new’  
end  
end

where “items” is a table and the domain partial a table row.

I’ve written an article on this subject, which you can find at

Please let me know if you find anything uncomplete, unclear or missing,
