"java.lang.NullPointerException" when using ExecuteMemoryTable?

[PenaManso]

Hello.

I am getting the above error when running the my app in the emulator.
Code compiles OK but when I use the related command button it crashes.
I am trying to get data from a table and create a CSV file from it using DBUtils.
Any idea of what might causing this?

Code is attached.
Log is as follows:
** Activity (main) Pause, UserClosed = false **
** Activity (activitysistema) Create, isFirst = true **
** Activity (activitysistema) Resume **
ExecuteMemoryTable: SELECT * FROM documentos_device WHERE TIPODOCUMENTO = 'CFA' ORDER BY DATACRIACAO,SERIEDOCUMENTO,NUMERODOCUMENTO,NUMEROLINHA

Thank you for your help.

SaveCSV fails because of a null value.

SaveCSV fails because of a null value.

Thanks Erel!
Indeed I had one empty field for some records.
I thought it could have NULL but it seems it is not so.

Wrongly blamed the ExecuteMemoryTable and in the end the issue was regarding SaveCSV.

I filled the empty one and it works just fine.

Thanks again for your quick answer.
