joomla #__associations table

[Rogerl]

I expired that joomla 2.5 supports menu item association, which enables it to change the language without necessarily being redirected to the front-page.I would like to generate a list containing all associated menu items of the current menu item. For example: I have three articles about the wheel, each in a different language, but about the same subject, associated with each other and clicking through the language switcher always delivers me the right page.The #__associations table in the database of joomla stores records consisting only of an id, a context and an md5 hash value, representing all the associations. How is this hash generated?Greeting philipp
