Editor / opener update error on save action

[Fxp]

When saving, editor try to update opener document which in Bluenet case is the main application (search window) but in trunk is the opener window :

• undefined if user type geonetwork url in a browser
• the opener window if the catalogue is opened from another webpage

The update could trigger JS errors if the opener is not the geonetwork expected page and does not release the screen.

Error in metadata-editor.js :

if(opener){divToRestore=opener.document.getElementById(f)

Should we check that opener contains 'main.home' in url ?
