Error when creating new project cloned from another

The solution was to create the new project without cloning, and then use the Sync Project System feature.



Go into Setup|System Configuration|Sync Project System Options, and sync the project: http://screencast.com/t/X4aCnt1iZ



This should take care of custom fields and choice lists, but folder structure and data are project specific and not included - just as with the "Project to Copy from" feature.



If you need to, you can copy folder structure from project to project (or from tab to tab) by right-clicking on the existing folder structure, select Copy Folder Structure.
