Changed Assigned User from @User_306070 to @anonymous Hello,The bug still exists on version 5.6.0 of Jaspersoft Studio (installed with the 64b installer). I have attached 4 pictures with the 4 steps described above and it's reproducible.I am using Windows 7 Enterprise 64-bit, build 7601, Java 1.7.0_u45_x64, Java 1.7.0_67_x64, Java 1.8.0_31_x64. Reproducible also with the 32 bit versions of Java (the ones mentioned above are the ones I used to check it).It's reproducible even if the query is empty in the beginning, with SQL, EJBQL, etc. query languages.
