Hi, I'm writing a web service client in Java and trying to add e.g. function: mail_domain_add(...) What should be a type of params? When I use mail_domain_get I get HashMap as return and everything is fine. When I try to use HashMap or LinkedHashMap as type of params everything looks fine as well. I get the mail_domain_id but all params (server_id, domain, active) are not set. As a result I add new mail domain but params values are empty.
