I have developed tons of reports, usint iReport 3.7.4, with no problems. Now, without changing any settings, I suddenly get "Document has no pages" and I am certain the data exists. I'm using a jdbc connection to Mysql, which has been working for nearly a year, with no problems. I know the sql works, because I can execute it from a Mysql prompt and also from within phpMYAdmin. Also, when I "test" the jdbc connection, it works fine. Also, if I run the compiled report outside of iReport, using the same jdbc connection, it works fine. One other problem that cropped up at the same time is, the heartbeat connection is failing. I disabled the heatbeat plugin to eliminate that message. However, I installed both 3.7.5 and 4.0.0 of iReport and I still get this failure as well as the "Document has no pages". I really need some ideas on this! Thanks in advance.
