Before, I had this in my RJS template:

```
page['order'].replace_html :partial => 'order'

```

When I use assert\_select\_rjs as follows:

```
assert_select_rjs :replace_html, 'order'

```

I get the error:

```
No RJS statement that replaces or inserts HTML content.

```

But when I change the RJS template to this:

```
page.replace_html 'order', :partial => 'order'

```

Then assert\_select\_rjs works fine. What gives?

Thanks,  
Eric

You need something like (from memory)  
assert\_select\_rjs :chained\_replace\_html, ‘order’

See the API docs for assert\_select\_rjs. Seem to remember there’s a bit  
about chained replace (but not much).

I see… I saw that chained replace thing too, was wondering what it was  
for… now I knows. Thanks.
