Empty page names in breadcrumbs on multi-lingual websites [5.2.2-B1]

The breadcrumbs allows to navigation easily up the website page hierarchy. Typical breadcrumbs look like this:

Home > Top Page Name > Sub Page Name

This works like a charm on website with single language, but on website with multiple languages page names might turn out empty because implementation issues of "\kNavigationBar::getCategoryParentPath" method. Here is what's wrong:

• shared cache is used for all language, but only page name on current language is stored in it
• there is no fallback to page translation on primary language in case if page isn't translated on current language
• if user opens website on non-primary language on which page name isn't translated AND cache is missing, then this empty page name is saved into cache

Solution

In the "\kNavigationBar::getCategoryParentPath" method:

1. use "\kMultiLanguageHelper::getLanguages" to iterate over all enabled languages and query translations of used categories on all languages
2. include language serial in cache key, to auto-reset cache when language is added/removed or primary language is changed
3. set category text for a given language into category text from primary language, when category text on given language is missing
