A PageDAO.getInfos request can be heavy. for example if several contents are in the page, each one will test all of its workflow action.

When a page is displayed but not focused, if the user directly select a zone inside :

• the tool get focused so it asks for page infos to send a bus event
• the zone is selected so it asks for page infos to send an other bus event

Currently both request are done and finally a single bus event is sent.
We can enhance this by not sending the first request at all
