SqlDeveloper 18.3 xmltype issue ORA-22275: invalid LOB locator specified

Hi,

There might be still an issue when displaying xmltype is SqlDeveloper 18.3:

For example, execute the following query:

select xmlforest(first_name, last_name, email)

  from employees;

and then double click in a cell of data grid.

Sometimes it shows data in xml format, and sometimes it

displays ORA-22275: invalid LOB locator specified.

Best regards,

Boris
