Hello Javier,
Thank you for this great extension which works as describe (from admin panel).
However when it comes to use this extension from an HTML interface there is an issue.
In the following file: /app/code/community/Jvs/FileAttribute/etc/config.xml I tried to move the whole following block from adminhtml to global node:
<jvs_fileattribute>
jvs_fileattribute/observer
updateElementTypes
</jvs_fileattribute>
that you can find in the block </adminhtml_catalog_product_edit_element_types> but it does not work...
Can you tell what I need to do to make it used at Global level?
Best regards,
Joel
