When the action selection page (associate as email, reference mail or internal note) displayed there are already two notices in the log:
[2016-06-13 13:52:07] app.NOTICE: E_NOTICE: Undefined index: unknown_contacts {"code":8,"message":"Undefined index: unknown_contacts","file":"/var/https/eventum.xxx.hu/var/cache/74052b47bde4d161151a14effecd4fa1986eeaed_0.file.associate.tpl.html.php","line":144} {"url":"/associate.php?cat=associate&item%5B%5D=19479&issue=existing&issue_id=7813&page_size=50&hide_associated=on","ip":"78.92.241.115","http_method":"GET","server":"eventum.xxx.hu","referrer":"https://eventum.xxx.hu/emails.php","file":"/var/https/eventum.xxx.hu/var/cache/74052b47bde4d161151a14effecd4fa1986eeaed_0.file.associate.tpl.html.php","line":144,"class":null,"function":"block_170527151575d3451188fd1_29983974","memory_usage":"1.75 MB","memory_peak_usage":"1.75 MB","version":"3.1.2","usr_id":"3"}

If one of the first two options, email or reference email is selected and continue is clicked there is a warning that some parameter is not passed and then the error:
[2016-06-13 13:55:15] app.WARNING: E_WARNING: array_values() expects parameter 1 to be array, null given {"code":2,"message":"array_values() expects parameter 1 to be array, null given","file":"/var/https/eventum.xxx.hu/src/Db/Adapter/PdoAdapter.php","line":171} {"url":"/associate.php","ip":"78.92.241.115","http_method":"POST","server":"eventum.xxx.hu","referrer":"https://eventum.xxx.hu/associate.php?cat=associate&item%5B%5D=19479&issue=existing&issue_id=7813&page_size=50&hide_associated=on","file":null,"line":null,"class":null,"function":"array_values","memory_usage":"1.5 MB","memory_peak_usage":"1.5 MB","version":"3.1.2","usr_id":"3"}

If the third option, internal note is selected then the foreach loop complains about its input and the page is not closed but reloaded but without the issue number passed this time:
