From 7bab769f7e0d0209dbd9b4d6f2429ef73ad8b70a Mon Sep 17 00:00:00 2001 From: Lukasz Lenart Date: Sun, 23 Nov 2025 12:54:20 +0100 Subject: [PATCH 1/3] docs(research): WW-5368 add OGNL label field access warning analysis MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Comprehensive research document analyzing the root cause of OGNL security warnings when using getText() with resource bundle keys starting with "label". Key findings: - UIBean has protected String label field without public getter - SecurityMemberAccess enforces public-only member access - OGNL property resolution happens before string concatenation evaluation - Warning is a false positive - expression works but triggers introspection Analysis includes: - Detailed OGNL evaluation flow through CompoundRootAccessor - SecurityMemberAccess check sequence and blocking mechanism - Select tag listValue processing and iterator stack manipulation - Comparison with similar protected fields in other components Recommended solution: Change protected fields to private with public getters to follow JavaBean conventions and eliminate warnings (Date component pattern).
