SQL Developer Data Modeler

Hi,

I'm getting the following error when trying to generate a report from my reporting repository:

In the log file, I can see these lines:

2016-02-13 10:17:12,995 [Thread-287] ERROR ReportsGenerationDialog - Generating report from Reporting Schema exception - ORA-29282: ID de arquivo inválido

ORA-06512: em "SYS.UTL_FILE", line 878

ORA-06512: em "REPOS.PKG_OSDM_UTILS", line 5634

ORA-01403: dados não encontrados

ORA-06512: em line 1

This happens either way if I put a directory object or a normal directory in the Directory Path.

Am I doing something wrong?

Here is a screenshot from the reports dialog:

Thanks
