Resolve critical TODO items and logic issues across all modules

dmealing · claude · dmealing · commit 7cec3361e88c · 2025-09-10T11:14:26.000-04:00
Major improvements: - Fix critical date parsing bug in ExpressionParser (format->parse) - Implement MetaObject inheritance checking in JSON readers - Add proper validation logic for ValueObject without MetaData - Enhance error handling in GeneratorUtil with null/empty checks - Add SLF4J logging for unsupported serialization types - Implement name consistency validation in DataObjectBase - Improve ArrayValidator logic for non-array values - Remove outdated TODO comments with proper documentation Technical debt resolution: - 11 files modified across core, metadata, and om modules - Enhanced error handling and logging throughout - Fixed 1 critical bug and multiple logic gaps - All changes compile successfully and maintain backward compatibility 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
