[Cartoweb-users] How to assign value to a textarea out of ajaxableplugin

[Oliver Christen]

Hi

first it would be interesting to know what the real error is.
if you have set the variable profile=development in your client.ini, when an 
error happen you should have the message "an error occured, clic ok to 
display the message" or something like that. The error returned will then be 
displayed at the bottom of the page or so.

Another thing, to update an element of the page by javascript, you need to 
add an "id" to your element, the value is usualy the same as the "name"
$('selection') means "get the element whose id is 'selection'.

And for textara, you cant use .value to set the value. You must use 
.innerHTML

regards
Oliver
