Hi, I have an error 'ORA-06536: In bind variable bound to an OUT position' when validating a FOEX form.

This validation is of type 'Function Returnig Boolean', the error occurs if there is in the validation anonymous block an assignment to a page item (same for an application item) see my example in : App ID: 384 Page:1003.
Thanks.
Note: 1- This error does not appear in an APEX form. 2- The validation does not execute if the validation level is page.
