this field "odlukakomentar" in database longtext type. solution ? thanks

according the docs (linking 5.0),

longtext [character set charset_name] [collate collation_name]

a text column maximum length of 4,294,967,295 or 4gb (2^32 − 1) characters. effective maximum length less if value contains multibyte characters. effective maximum length of longtext columns depends on configured maximum packet size in client/server protocol , available memory. each longtext value stored using 4-byte length prefix indicates number of bytes in value.

you might want check configuration of database driver, actual length (i doubt come close 4g bytes). if service-builder component (because you're mentioning liferay), might want google "liferay service builder model hints" , give service builder better hint of expected column sizes.
