Hello Nhomar Hernández,

Sorry for any inconvenience, this is a real bug.

It has been fixed today.

Would you please update your code?

However, it can only occur when you do not provide password while creating new entry.

Password is not shown, as its encrypted.

Thank you for reporting.

You may close this thread.

Hello,
I've encountered this problem too, where could I find the code up to date ? In openobject website download section, the module is dated of the 15th of april, 2009.
thank you
