BSL252 - ThisObject assign

← All rules

Summary

ThisObject assign

Identifiers

Field Value
Rule code BSL252
Compatible alias ThisObjectAssign
Severity ERROR
Without configuration Yes
BSLLS JSON, ON mode without overrides Yes
Registry flag implemented Yes
Tags correctness, suspicious

The implemented flag describes the registry; it does not certify verified BSLLS parity.

Behavior

  • The public identifier BSL252 and alias ThisObjectAssign are stable.
  • The rule reports the cases documented on this page.
  • Suppressions and project configuration are applied before publication.
  • The rule requires neither an external analyzer nor network access.

Configuration and suppression

BSL### is the primary stable identifier. The compatible alias is accepted in select, ignore, and compatible block suppression comments.

[tool.onec-hbk-bsl]
select = ["BSL252"]
ignore = ["ThisObjectAssign"]

All three suppression families support both a current line and a range. When an opening comment follows code, it affects only that line. Use any one form:

  • noqa:
Value = "example";  // noqa: BSL252
  • bsl-disable:
Value = "example";  // bsl-disable: BSL252
  • compatible BSLLS form:
Value = "example";  // BSLLS:ThisObjectAssign-off

When the same opening comment is on a line by itself, it starts a range. Close it with the matching marker from the same family:

// noqa: BSL252
// code without this diagnostic
// noqa-enable: BSL252

// bsl-disable: BSL252
// code without this diagnostic
// bsl-enable: BSL252

// BSLLS:ThisObjectAssign-off
// code without this diagnostic
// BSLLS:ThisObjectAssign-on

To disable the rule until the end of the file, omit the closing noqa-enable, bsl-enable, or BSLLS:…-on marker.

Opening and closing markers must belong to the same family.

Description

In managed form modules and common modules, there should not be a variable named "ThisObject".

Often this error appears when updating the platform version: the "ThisObject" property of managed forms and common modules appeared in version 8.3.3 which could previously be used as a variable name.

Examples

Incorrect: 

ThisObject = FormAttributeToValue("Object");
