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

[LATZE Carolin]

Hi all,

I know, that this might be a dumb question, but I'm lost and I don't find any solution by myself. I wrote my own plugin, which should write something into a textarea if the user selects something in a dropdown list. Without Ajax, no problem, but I can't find out how to do it with Ajax. Here are the details:

In cartoclient.tpl I defined the dropdown menu and the textarea:

<select name="col" onchange="javascript:CartoWeb.trigger('refsel.submit','formItemSelected()');">
{html_options values=$col_values output=$col_output selected=$col}
</select><br />
Selection:<br /><textarea type="text" name="selection" cols="30" rows="10" >{$current_selection}</textarea><br />


Then I defined a new plugin called refsel, which implements ajaxable. The implementing methods:

    /*
     * Ajaxable methods
     */
     public function ajaxHandleAction($actionName,PluginEnabler $pluginEnabler){
         switch($actionName){
             case refsel.submit:
                 $pluginsDirectives->disableCoreplugins();
                 $pluginsDirectives->enablePlugin('refsel');
             break;
         }
     }
     
     public function ajaxGetPluginResponse(AjaxPluginResponse $ajaxPluginResponse){
         $ajaxPluginResponse->addVariable('sel','HelloWorld');
     }

In refsel.ajax.js I defined:

AjaxPlugins.refsel = {
    handleResponse: function(pluginOutput){
        $('selection').current_selection=pluginOutput.variables.sel;
    }
};
 
/*
 * Plugin Actions
 */
 AjaxPlugins.refsel.Actions = {};
 AjaxPlugins.refsel.Actions.submit = {
     buildPostRequest: function(argObject){
         return AjaxHandler.buildPostRequest();
     },
     buildGetRequest: function(argObject){
         return '';
     },
     onBeforeAjaxCall: function(argObject){
    },
    onAfterAjaxCall: function(argObject){
    }
 }

I know, there has to be something wrong with handleResponse, since I get

Error: AjaxHandler.actionRequest(): received response is malformed!

when I try to use the plugin. I tried several different versions of handleResponse, but I can't find out how to do it the right way.

Is there somebody, who can help me with this little (but annoying) problem? I would be very grateful :-)

Thanks in Advance!
