We are using JasperSoft 5.5 and are building reports using the "Table component". Ideally, we would like the report to run with some columns initially hidden. This works fine. However, if I try to "Show" a hidden column nothing happens and I see the error message: "Uncaught TypeError: Cannot read property 'config' of undefined" This is the error in Chrome. In Firefox I see "jive.elements[args.columnUuid].config.parentId is undefined" The only way I can seem to get the Show/Hide functionality to work is if a select "Show All". I can then hide and show columns while I have the report open. But if I rerun the report the same error happens again. It appears to be an error in the follow file: jasperserver-pro/reportresource/reportresource?resource=net/sf/jasperreports/components/headertoolbar/resources/require/jive.interactive.column.js on line 425. Has anybody else experienced this issue? Thanks, Greg
