I used RJS extensively in my last web app with no problem.

I’m just beginning a new one and having a very odd problem.

The called method, get\_names, retrieves some values from the database,  
then ends:

render :layout =\> false

the get\_names.rjs file is rendered into Javascript, but then is just  
dumped as Javascript (text) into the browser:

e.g:

try {  
Element.update(“this\_panel”, “”);  
new Insertion.Bottom( … );  
} catch (e) { alert(‘RJS error:\n\n’

Any ideas?

Thanks!

Does the link\_to\_remote by any chance have an :update =\> ‘this\_panel’ in  
it ? That would take the reuslt of the Ajax call and update the div.  
I often make this mistake if I start with an update and replace it with  
RJS.

Alan–no it’s just this:

```
		<%= form_remote_tag :url => { :controller => "name", :action => 

```

“get\_name”} %\>  
Enter your name:  
\<%= text\_field “name\_input”,“name”, :size =\> 20 %\>  
\<%= end\_form\_tag %\>

Can you paste your .rjs file? Like Alan I have seen this before when  
setting :update but since you are not doing that the problem may be in  
the rjs.

Also, did you remember to add the javascript tags to the layout ?

One other problem might be content type. If you copy the code from the  
rjs into the action and use render :update instead, does it work there ?
