App State

In UI5 applications, you have the ability to save the current app state and return to it later. A similar functionality is supported in the abap2UI5 framework too.

Usage

Each state is saved as a draft with a unique ID, you can display this ID in the URL using the client->set_app_state_active method. This command generates a URL that you can copy&paste into another browser window. An example URL looks like this:
.../sap/bc/z2ui5?sap-client=001&app_start=z2ui5_cl_demo_app_000#/z2ui5-xapp-state=024251849E5A1EDFB1DAE2C97C8CE8C2

Sample Code

Below is an implementation of the app state functionality:

CLASS z2ui5_cl_sample_app_state DEFINITION PUBLIC FINAL CREATE PUBLIC.
 
  PUBLIC SECTION.
    INTERFACES z2ui5_if_app.
    DATA mv_quantity TYPE string.
 
ENDCLASS.
 
CLASS z2ui5_cl_sample_app_state IMPLEMENTATION.
  METHOD z2ui5_if_app~main.
 
    IF client->check_on_navigated( ).
      DATA(view) = z2ui5_cl_xml_view=>factory( ).
      client->view_display(
        view->label( 'quantity'
            )->input( client->_bind_edit( mv_quantity )
            )->button(
                text  = 'post with state'
                press = client->_event( val = 'BUTTON_POST' )
              )->stringify( ) ).
    ENDIF.
 
    CASE client->get( )-event.
      WHEN `BUTTON_POST`.
        client->message_toast_display( `data updated and url adjusted` ).
        client->set_app_state_active( ).
    ENDCASE.

  ENDMETHOD.
ENDCLASS.
