The following function is used to set the XML id and record id on a CDF component in the OnBeforeSerialize XML code. This can prevent getting NULL object errors when trying to set the CDF record id on complex screens in the OnAfterDeserialize code area. The code is setup to be included in a package titled "utils", change the package name on the declaration line to add it to any other package.
