Hello,  
I am using jQuery for all ajax stuff and recently got following error:

ActionView::TemplateError (private method `gsub’ called for #\<Array:  
0x2425ae8\>) on line #1 of…

and the code where it happens:

$("#notice\_ajax").before(’

\<%= escape\_javascript  
(flash.delete(:notice)) %\>
’).remove();

when I remove ‘escape\_javascript’ then everything works fine.

It seems that ‘gsub’ thinks that its argument (flash.delete(:notice))  
is an array…??

Any suggestion??

Thanks,

Check to make sure that the argument contains what it’s supposed to.

No it is a string. As in my initial post if I remove escape\_javascript  
then the code works fine.
