Hi, i am getting the below error after i migrated from gwt 2.6.1 to gwt 2.8.1.
am trying to pass an "LinkedHashMap<String, Object> " object thats causing the trouble. I am getting this issue only during post request. Linkedhashmap is working perfectly with get request. Any help is highly appreciated. Let me know if you need additional info to help me.
