Hi,
I am experiencing the following date format problem in APEX. (Look that APEX says me to use the same date I am inputting)

This happens in the Cloud and apex.oracle.com (Version 23.1).
To reproduce the problem:
- Create an app with the following Globalization Attributes.

2. Create an Date Picker item (with NO format mask) and a button to submit the page
3. In the Security Attributes > Initialization PL/SQL Code, type the following code:
BEGIN
EXECUTE IMMEDIATE 'alter session set nls_date_format = ''YYYY-MON-DD'' ';
END;

4. Select any date and click the button in the page and the error message is shown.
