The average of the karma doesn't show right away. I always try to clean the cache and cookies of the browser, I also login and log out several times, etc..and nothing, it always show the last vote instead of the average. Only, if I run again the project in eclipse again it updates the average (number of stars). For example, if the post already had 2 votes, and then, another user votes 5, the stars become 5 instead of 4 stars. Do you know what is happening?
