I ask for your support to fix an error. Insert a table for my report, when I try to modify it Jaspersoft crashes, I can't change column sizes, font, or anything. I restarted about 10 times Jaspersoft, installed the latest version (6.17) but the same thing happened. I run my Query in pgadmin (postgresql) and it does the query in seconds, it presents no problems. In addition, I have created the report several times and the same thing happens to me. I don't know what else to do, I hope you can help me.
