Hello Christophe and thank you very much for your reply. This issue does sound like my problem. However, this may go back to my other problem listed. ( And forgive me if I ask a question that could have been easily tested, but I am actually home on vacation without all my code, but remain quite intrigued by this problem ). With both these code snippets, I had been trying to test update and versioning. When my checkin() failed on update, I allowed the program to still try to iterate through the versions, simply to see if I would get results. Seeing as update failed and there were no other versions, it makes sense that the link you sent is that problem. This leaves a couple questions for me. - Since my checkin() is failing, do I have any real way to test the getObject by version? If I do a modify object, update() and save(), can I test versioning without actually doing the checkin()? - If I use the versionIterator to iterate through versions in the future, should verifying that Version.getName() is not jcr:rootVersion be the best way to take care of the problem you linked to me? - According to the JCR spec (8.2.5), the InvalidItemStateException is thrown if the versionalbe node has unsaved changes pending, which clearly I am doing on the line before the checkin(). Do you have any input on this?
