Features include:

• Observable object model with real-time property/event tracking
• Dynamic property paths, calculated properties, and triggers
• Full object graph management, lazy loading, and caching
• Built-in sync event architecture for distributed systems

oa-jfc

oa-jfc is a rich, model-bound Java Swing framework that uses oa-core to dynamically bind UI components to data. It supports real-time updates, form validation, UI rules, and full MVC-style structure — without requiring boilerplate UI code.

• Live UI sync with OAObjects and Hubs
• Forms, tables, trees, and custom components
• Integrated reporting and print templates
• WYSIWYG layout support

oa-web Coming Soon

oa-web is the newest addition to the OA platform, bringing the power of the OA model to modern web applications. It is the successor to the legacy oa-jsp library, designed from the ground up to support reactive, real-time web development using OAObject and Hub. With OA-Web, developers get a modern replacement for Java Server Pages — one that's fully model-bound and sync-aware. Built for real-time sync, dynamic templates, and full model binding — it lets developers build complex, data-driven web interfaces without manually wiring the UI.

• Full-stack sync between web UI and OA model (via object events)
• Dynamic HTML binding from server-side templates
• Support for trees, lists, forms, and multi-window UI
• Works directly with OAObject and Hub — no API scaffolding needed
