I’m having a strange display issue when trying to update a tablerow  
using RJS.

This is the code in the RJS template:

page.replace\_html “item\_#{@item.id}”, :partial =\> ‘item\_display’

So the existing

 has an id like item\_1. When the update actions  
completes, it renders this template and effectively replaces the tr with  
item\_display which as a tr of its own. The issue is, the new row doesn’t  
span the width of the table.

Has anyone encountered this before?

Thanks.

Most/all browsers don’t have any support for DOM manipulation of tables.  
Not sure why, its a real pity. You’ll need to come up with a hack for  
it. I think the [ajaxscaffold.com](http://ajaxscaffold.com) solution includes some code that works  
with table dom manipulation.

Make sure you enclose your TRs in a TBODY tag.

Zack,

That does help for not getting the IE error, but still when updating a  
row by replacing it with a partial, doesn’t render it correctly.

Thanks.
