I can add a table to a report through the wizard with no problems. When I try to add a column to an existing table (at the end.. at the beginning etc)nothing happens (even not an error message shows up) but I see the below error in the logfile. I've installed Jaspersoft Studio 5.2.0 with jdk-7U40, I also tried it with jre-7U40 to no avail. Jaspersoft Studio is installed on a 2008R2 Datacenter server and the workspace is located on a network share. Is this a bug?
I can run the report though and its compiled ok.
