axaptapedia: Validate field values on form
Источник: http://www.axaptapedia.com/Validate_...values_on_form
============== Summary: Validating a field on a form A nifty trick for comparing the "old" value against the "new" value using "obj.orig()" when validating a field on a form. Example: Change the behavior of the "Customer Group" on "CustTable" form. Overwrite the method "validate" on the field "CustGroup" on the data source on "CustTable" form. Original method: X++: public boolean validate() { boolean ret; ret = super(); return ret; } X++: public boolean validate() { boolean ret; ; if(custTable.orig().CustGroup == '30') // Non changeable group. { info('You cannot change this Customer group'); ret = false; } else { ret = super(); } return ret; } Источник: http://www.axaptapedia.com/Validate_...values_on_form
