The raw document type doesn't support headers, thus the missing method.

What I wonder is how you end up calling a module in the document type "raw" (JDocumentRaw). That sounds more like a bug in the extension to me. JDocumentRaw certainly isn't meant to produce HTML pages (containing modules and all).

You suggested code likely would work in that it doesn't create a fatal error anymore. However I don't think it's the best idea as it looks more like a workaround for messy coding in another place.

Thanks for your reply.

I'm using AJAX call to refresh a module.
In javascript I use the following:

function moduleRefreshSendAjax (moduleName, moduleId, modulePosition, num){
var data = {
"option": "com_ajax",
"module": moduleName,
"method": "refresh",
"moduleid": moduleId,
"position": modulePosition,
"format": "raw"
};

    jQuery.ajax({
        type: "POST",
        data: data,
        success: function (res) {
            jQuery('.news-' + moduleId).html(res);
        },
        error: function (res) {
            console.log("ERROR: " + res.responseText);
        }
    });
};

And in the server side I use the following method:
public static function refreshAjax() {

$position = $_POST['position'];
$moduleId = $_POST['moduleid'];
$modules =& JModuleHelper::getModules($position);
foreach ($modules as $module) {
if ($module->id == $moduleId) {
return JModuleHelper::renderModule($module);
}
}
}

Is there other good solution to return module HTML from ajax call?

Thanks in advanced

Ah I see. hat should be a valid usecase indeed. Can you make a PR with your suggested changes?
