Grails Plugin Uploadr does not get rendered after Ajax call

Question

I've got the following problem, I am using Grails in my application. I like to edit an entry called 'task', so a Foundation 5 Reveal pops out and is showing my form. This Reveal is a template and is being rendered after a click on the edit button of the task, I call my controller with Ajax and put the new data in my Reveal div.

The problem is, that the new data is containing my Uploadr plugin tag and it does not get rendered, it makes sense, but how do I solve this?

<uploadr:add name="myFirstUploadr" path="res/img/aufgaben" 
allowedExtensions="gif,png,jpg,jpeg"/>

and I am getting following Stacktrace:

Answer 1

Solution for this is simple, adding the require tag for the Uploadr Plugin to the partial View, not the main layout, so javascript and dependencies can be resolved even on Ajax-Call.

<r:require modules="uploadr"/>

<uploadr:add name="editTaskUploadr" path="${imagePath}" 
                 allowedExtensions="gif,png,jpg,jpeg">

<r:layoutResources/>
<r:layoutResources/>

Has done it, simplified.
