Replace IteratorExpenseNote with NewExcelExport. You are trying to set the IteratorExpenseNote end of the association to IteratorExpenseNote, but you need to set this end to NewExcelExport.
Hey thanks Thorsten.
I changed what you said
My error is gone but when testing I still have problems on my Java call. Any idea? I looks like I have no items. When debugging I have items in my ExpenseNoteList.
Once again, thanks!!
Can someone explain me what Thorsten means with “Create a dedicated input object that refers to your row objects instead of associating the row objects to the ExcelExport object. “ please? I tried so many things. I also tried this one https://forum.mendix.com/link/questions/105004.
Normally my config for Excel is correct. I still have issues with the Input object in my Java action…
