remoteFunction call is not working grails

Question

I am trying to call a function once a selection is made in the drop down menu. Here is my code for the drop down menu in my list.gsp for the 'Code' domain class:

<td><g:select name="data" from="${codeInstance.datas.language}" 
          onchange="${remoteFunction(action: 'translationById')}"/> 
</td>

And here is the function I am trying to call. This is in my CodeController:

def translationById = {
        println "Fine"
        //println params;
    }

I am just trying to print out "Fine" so I know that the function was called, but "Fine" never gets printed. Why is the function not getting called?

Answer 1

Instead of using a closure, use a method, like:

def translationById() {
        println "Fine"
        //println params;
}

Also, use some browser debugger like firebug or similar to see if error message is being displayed.

What happens if you put an alert inside the onchange event instead of a remoteFunction? If the alert is displayed, then I think your problem is with the prototype library. Add the prototype library to your header. Like <g:javascript library="prototype" />.
