Hello, Today I have to deal with a new problem. I have a table with a connection to a db , the same as in the main report. The dataset contain the right query (if I try to read fields them work properly), but when I put into the table textfield the fields that I read from the dataset the table, in the preview, disappear. If i also try to print the field in a separate TextField into details space it works. I've already tried to change dataset and I've checked if all parameters required are into the dataSet.Query is correct, it's been tested into pgAdmin. I'm using jaspersoft studio and postgresSql. Need help asap. Thnx
