When remove :
CASE WHEN w.object = "firms" THEN "Firma" WHEN w.object = "persons" THEN "Osoba" END as object, CASE WHEN w.object = "firms" THEN f.firmname WHEN w.object = "persons" THEN CONCAT(p.lastname, " ", p.firstname) END as objectname,

Query is ok

After upgrade form 4.2.1 > 4.2.2 i have error durign response .

====

finaly i change all CASE to separate select:
->select("CASE
WHEN w.object = "firms" THEN "Firma"
WHEN w.object = "persons" THEN "Osoba"
END as object", false)
->select("CASE
WHEN w.object = "firms" THEN f.firmname
WHEN w.object = "persons" THEN CONCAT(p.lastname, " ", p.firstname)
END as objectname", false);

and work ok
