session-stickyness (#1435) 
* Added Component and Session Stateful (#1433)

- Added Component support (TODO refactoring sap.z2ui5 and view handling -> instead of .placeAt use mainView of component manifest)
- Added Session Stateful support

*add the following lines to your REST handler in order to support stateful session handling*
'''abap
    if attributes-stateful-switched = abap_true.
      server->set_session_stateful( stateful = attributes-stateful-active ).
    endif.
'''

And here is an ABAP example class for testing session handling

README.md



...offers a pure ABAP approach for developing UI5 apps - entirely without JavaScript, OData or RAP. Just like in the past, when a few lines of ABAP were enough to display input forms and tables using Selection Screens & ALVs. Designed with a minimal system footprint, it works in both on-premise and cloud environments.

Key Features

  • 100% ABAP: Developing purely in ABAP (no JavaScript, DDL, EML or Customizing)
  • User-Friendly: Implement a single interface to create a standalone UI5 application
  • Minimal System Footprint: Uses a simple HTTP handler (no BSP, OData, CDS or RAP)
  • Cloud & On-Premise Ready: Supports both ABAP Cloud and Standard ABAP
  • Broad System Compatibility: Runs on all ABAP releases (from NW 7.02 to ABAP Cloud)
  • Easy Installation: Install via abapGit, no additional app deployment required

Compatibility

  • BTP ABAP Environment (ABAP for Cloud)
  • S/4 Public Cloud (ABAP for Cloud)
  • S/4 Private Cloud or On-Premise (ABAP for Cloud, Standard ABAP)
  • R/3 NetWeaver AS ABAP 7.50 or higher (Standard ABAP)
  • R/3 NetWeaver AS ABAP 7.02 to 7.42: Use the downported repositories
