I have seen others post about this problem and have run into it also but with help was able to work thru, except now. I am using the following code to create a child of a contentnode, add a field, assign a value. When executed, the code says the field is created but really it's not.
I basically coped the second code from another part of my app that works fine. The print of dataitem.zip displays correctly but the print of the content doesn't show the field as being added. What else could be done?
