Cannot add Package Installer Element

[machadoug]

I installed EasyCreator 0.0.10 and it is great, however I Cannot add Package Installer Element.

Firebug gives me the following Javascript Error:

Code:

$("element_name") is null
elementName = $('element_name').value
addelement.js (line 13)

I've manage to create those files and include manually in the manifest file, however I have to manually add to the manifest file every time that I need to edit the component.


Thanks in advance.
