This is a bug that combines Hierarchy, Versioned and LeftAndMain admins and CMSSiteTreeFilters.
This bug can be reproduced by having a large site tree with enough deleted pages in it so it doesn't
pre load all the children pages when initially opening an admin. Filter by either 'All pages including deleted'
or 'Deleted pages'. For CMS users it will look like deleted pages are gone.
The solution involves a couple of smaller fixes in both CMS and framework modules.
1) Ensure that 'numHistoricalChildren' are used instead of 'numChildren' when dealing with deleted pages
2) LeftAndMain::currentPage() deletes all the 'marking' cache previously built up by Hierarchy::markPartialTree()
3) Use Versioned::get_included_deleted() instead of raw DB queries against the DataObject tables when calculating parents in CMSSiteTreeFilter
1. Add missing _super calls.
2. Make UI widget destroys more consistent to avoid exceptions.
Selectable would throw an exception in the GridField.js if destroy
called from onunmatch - at that stage jQuery UI would have had called
the destroy already. Add a guard, and change to onremove, which triggers
before the element is removed from DOM.
3. DOM traversal fails after the element is removed from DOM.
Onunmatch triggers after the removal of the element from the DOM, which
makes DOM traversal fail. Use onremove instead, which triggers while the
element is still in DOM.
While the check for `$classname` was done in the first conditional, it was left out of the other two, leading to potential issues when an invalid ID was given, instead of the expected `false`.
The WYSIWYG by default creates invalid HTML5. Creating a table and running it through W3C validator returns the following error: The border attribute on the table element is obsolete. Use CSS instead.
Broke because the <form> tag was returned, while
the client logic was expecting the whole <div> including the <form>.
Fixed to display the button bar at the bottom,
and tested with validation errors as well as switching from/to
the panel via ajax.
See https://github.com/haml/haml/issues/269. Seems that OS X Mavericks causes this to occur, even when system default is set to utf-8.
Force encoding in admin scss as well
The files are uploaded to transifex.com now, which means we needed
to consolidate the file names (= locales). Since Transifex doesn't allow
arbitrary JavaScript structures, we're using an intermediary JSON
format which gets transformed into the JS used by the framework.
See b59f3858af for generator logic.
