3728765 - Some widget types (e.g., DropDown) are no longer recognized as valid after QRC Q1 2026 version

• From an existing application converted to ODE story version :
  - In 2025.21.14, before QRC1 2026, the function ArrayUtils.create(Type.CheckboxGroup); or ArrayUtils.create(Type.Dropdown); or ArrayUtils.create(Type.ListBox); are still supported and recognized : thus it runs without error.
  - In 2026.2.4, after QRC1 2026, the function ArrayUtils.create(Type.CheckboxGroup); or ArrayUtils.create(Type.Dropdown); or ArrayUtils.create(Type.ListBox); are NOT supported and is not recognized anymore : thus it runs with error :
  Script execution failed for event "Timer_onInitialization_step1.onTimeout"
  Correlation ID: 1156829140164985b402141173176822
  app.chunk.1546.41c1f…e4948d7c1a1c4.js:21 Script execution failed for event "Timer_onInitialization_step1.onTimeout" Validation error in "SCRO_Main.FUN_Init_Var_Filters": "Dropdown" is an unused property. (42, 37) Invalid argument at index 1: Cannot convert from "Unknown type" to "Type". (42, 37) This function has no return value. (42, 25) "undefined" is an unused property. (49, 74)

• Note that if we create from scratch a new ODE story, these 3 functions ArrayUtils.create(Type.CheckboxGroup); or ArrayUtils.create(Type.Dropdown); or ArrayUtils.create(Type.ListBox); are not supported neither in 2025.21.14 nor 2026.2.4.

• SAP Analytics Cloud 2026.2.4

The current behavior reflects the correct implementation.

Why It "Worked" Before (2025.21):

Before QRC1 2026, once a basic widget(like button, dropdown, checkboxgroup...) is inserted into canvas in design mode, internally we would eagerly load all basic widget APIs regardless of which widgets were actually used in the story:

  - When you inserted a button, the system loaded all APIs for basic widgets like button, checkboxGroup, radioButtonGroup, dropdown, listbox...
  - These widget types were registered in the Tern type system's global scope, so you may use script like "Type.Dropdown" even if your document does not contain any dropdown widget.

Why It Breaks Now (2026.2.4):

We did some improvement of the API loading strategy, which has been changed to on-demand loading:

  - If your story only uses button widget, only the button API and its tern type is loaded, checkboxGroup, Dropdown, and ListBox APIs are NOT loaded unless those widgets are present in the story
  - Without these APIs loaded, Type.CheckboxGroup doesn't exist in the Tern type system, which results in the error in both design mode and view mode.

Thus, story needs to be reviewed and lproblematic ArrayUtils.create() statements should be deleted or modified.
