The exception is thrown from iReport plugin. Reassigning to plugin owner. Please evaluate it. Thank you.
This also happens to me in netbeans 7.4 under java 7. It seems to be caused by document preview which puts the document in a closed state. a workaround - after previewing (which saves the report successfully) just close and reopen the document before making any additional changes (so you can save it). how to replicate: 1. load a report 4. switch to preview 5. switch to design 6. move an element 7. save report (JrxmlEditorSupport exception) It seems that preview mode is somehow causing the document to be marked as closed and its losing its document reference hence JrxmlEditorSupport:saveDocument is returning null for getDocument() (line 267). it does this even if the document doesn't need to be (and isn't) saved automatically on preview. I haven't yet been able to trace how the document is getting closed on preview.
