Feb 1, 2025February 2025: Focused on development ergonomics, UI consistency, and flexible data modeling in SAP-samples/cloud-cap-samples-java. Delivered four features and one bug fix, plus maintenance updates. Highlights include aligning the bookshop app with the CAP Java archetype for local development using H2; centralizing i18n texts for attachments via the cds-feature-attachments plugin; introducing (and subsequently pruning) a Map-based details feature for Books/Authors; and updating dependencies for plugin compatibility. A notable bug fix involved disabling native HANA associations to prevent conflicts with default association handling. These efforts improved development reliability, UI consistency, and demonstration clarity, while enhancing maintainability and integration with the attachments plugin.
