Description

Accessing data via CurrentRow of dynamic list (CurrentRowAccess)

Diagnostic description

Accessing properties or methods via CurrentRow of a dynamic list triggers a database object read per row. Use CurrentData instead, which works with already-fetched row data.

The diagnostic only fires for form tables displaying a dynamic list (type TableForm.DynamicList). Tables over tabular sections, value trees and other form data do not touch the database when accessing CurrentRow — no diagnostic is reported there.

Examples

Incorrect

Value = List.CurrentRow.Name;
List.CurrentRow.Write();

Correct

Value = List.CurrentData.Name;
