Syncronize across translations
==============================
Faceted navigation is a multilingual package and all the faceted settings are
keept in the canonical portal object. All you need to do to syncronize across
translations is to subtype all translations as faceted navigable. For this
a syncronize action was added within object_buttons menu items.

Set up
------

    >>> portal = layer['portal']
    >>> request = layer['request']
    >>> sandbox = portal['sandbox']
    >>> sandbox.setLanguage('en')

Add some translations

    >>> _ = sandbox.addTranslation('fr')
    >>> _ = sandbox.addTranslation('ro')

Subtype canonical as faceted navigable

    >>> from zope.component import getMultiAdapter

    >>> subtyper = getMultiAdapter((sandbox, request), name=u'faceted_subtyper')
    >>> subtyper.enable()

Let's cleanup default criteria to avoid surprises

    >>> from eea.facetednavigation.interfaces import ICriteria
    >>> cids = ICriteria(sandbox).keys()
    >>> for cid in cids:
    ...     ICriteria(sandbox).delete(cid)
    >>> ICriteria(sandbox).keys()
    []

Let's add some configuration

    >>> handler = sandbox.unrestrictedTraverse('@@faceted_configure')
    >>> _ = handler(addPropertiesWidget_button='Add',
    ...   wtype='text', wposition='left', title='Text widget',
    ...   index='Title', default='water')

Now let's try to get faceted navigation configuration from french

    >>> fr = sandbox.getTranslation('fr')
    >>> fr.unrestrictedTraverse('@@facetednavigation_view', 'Ops, AttributeError')
    'Ops, AttributeError'

Syncronize
----------

    >>> sync = sandbox.unrestrictedTraverse('@@faceted_sync_translations')
    >>> _ = sync()

Let's check again the french translation

    >>> fr_view = fr.unrestrictedTraverse('@@facetednavigation_view')
    >>> [widget for widget in fr_view.get_widgets()]
    [<eea.facetednavigation.widgets.text.widget.Widget object at...>]

What about the romanian one?

    >>> ro = sandbox.getTranslation('ro')
    >>> ro_view = ro.unrestrictedTraverse('@@facetednavigation_view')
    >>> [widget for widget in ro_view.get_widgets()]
    [<eea.facetednavigation.widgets.text.widget.Widget object at...>]

Ok, what if I edit or add a widget elsewhere than the canonical?

    >>> ro_handler = ro.unrestrictedTraverse('@@faceted_configure')
    >>> _ = ro_handler(addPropertiesWidget_button='Add',
    ...   wtype='select', wposition='right', title='Select widget',
    ...   index='portal_type', default='Folder')
    >>> [widget for widget in ro_view.get_widgets()]
    [<eea.facetednavigation.widgets.text.widget.Widget object at...>, <eea.facetednavigation.widgets.select.widget.Widget object at...>]

Let's check if the changes are available for the other languages

    >>> [widget for widget in fr_view.get_widgets()]
    [<eea.facetednavigation.widgets.text.widget.Widget object at...>, <eea.facetednavigation.widgets.select.widget.Widget object at...>]

    >>> en_view = sandbox.unrestrictedTraverse('@@facetednavigation_view')
    >>> [widget for widget in en_view.get_widgets()]
    [<eea.facetednavigation.widgets.text.widget.Widget object at...>, <eea.facetednavigation.widgets.select.widget.Widget object at...>]
