Onco,
For the error with the identifier please have a look at this forum question: https://forum.mendix.com/link/questions/20022
The other issue has to do with the import of the pdfmergerutility class. In the latest version for Mendix 6 the import should read:
import org.apache.pdfbox.multipdf.PDFMergerUtility
Hope this helps in fixing your issue.
