Removed some unecessary interceptor work. Fixed content filtering to default to the pivot translation if there is no translation for a required language. Fixed content filtering when switching back to ALL LANGUAGES. git-svn-id: https://svn.alfresco.com/repos/alfresco-enterprise/alfresco/HEAD/root@5802 c4b6b30b-aa2e-2d43-bbcb-ca4b014f7261

/**
|
|
* Multilingual support implementation.
|
|
* <p>
|
|
* The basic structure supported is that of a hidden container of type
|
|
* <b>cm:mlContainer</b> containing one or more secondary children of
|
|
* type <b>cm:mlDocument</b>. One of these will have a matching locale
|
|
* and is referred to as the <i>pivot translation</i>. It is also possible
|
|
* to have several transient <b>cm:emptyTranslation</b> instances that
|
|
* live and die with the container until they get their own content.
|
|
* <p>
|
|
* It is not possible to guarantee that there is always a pivot translation
|
|
* available in the set of sibling translations. The strategy is to hide
|
|
* all translations when there isn't a pivot translation available. A
|
|
* background task should be cleaning up the empty or invalid <b>cm:mlContainer</b>
|
|
* instances.
