Question

I would like to be able to perform some logic in the table.modifiedField method which compares the previous value of a field to the new value. How do I get to the previous value?

Answer 1

The record buffer as it was before any modifications is available through the this.orig() method.

public void modifiedField(fieldId _fieldId) {     super(_fieldId);     info(strfmt('Field number %1 changed from %2 to %3',_fieldId,this.orig().(_fieldId),this.(_fieldId))); }
