I would suggest downloading the latest version of the Excel Exporter module from the Marketplace. You may also need to upgrade the Mx Model Reflection model as well.
Good luck!
The OutputDocument variable cannot be assigned a value because it is declared final, which means it cannot be changed once assigned. You probably need to remove the final keyword before declaring the OutputDocument variable to be able to change its value in your code.
I got a warning when import the Excel Expoter module. the below files will be replaced with the new one
C:\Users\miyaqian\Mendix\Inclination_Test-main\userlib\joda-time-2.10.10.jar
C:\Users\miyaqian\Mendix\Inclination_Test-main\userlib\joda-time-2.10.10.jar.XLSReport.RequiredLib
after I continue, there's an error in below box
