Ran across another Forms Publisher bug in 7.5 during testing. If you have nested containers, and you attempt to set the label (item.setLabel()) on the child replicants, the command fails and drops you out of the function. Then you can't save the DCR. This all works fine in 7.3.2. They really effed up Forms Publisher in this version. I have to wonder if they do any amount of thorough testing when they release a new version.
