I am creating a site by copy.
All parameters are copied to the new configuration, except title and URL (of course), but also binary parameters.
In my project, I have binary site parameters defined like this:
<param id="my-site-logo" type="binary" multiple="false"> <label>Logo</label> <description>Logo</description> <category>Ma catégorie</category> <group>Présentation</group> <validation> <mandatory/> </validation> <order>20</order> </param>
