3042989 - SAPUI5 fails to load fragment after upgrading to SAPUI5 1.60.X and later (in relation to iconTabBar)

Symptom

  • Definition: What is a SAPUI5 fragment?
    • Fragments are light-weight UI parts (UI sub-trees) which can be reused, defined similar to views, but do not have any controller or other behavior code involved
    • UI parts which are to be used in several views cannot be easily defined
    • They either have to be created as new controls, or they have to be created as views
    • Creating them as new controls results in a development overhead, while creating them as separate views results in a runtime overhead. In the latter case they would have a separate controller instead of having the same controller as the view does
    • Also, views and popup controls like dialogs do not go well together
    • The dialog content can be defined as a view but the dialog control itself always has to be written in the program
    • To solve these issues, fragments have been introduced
      • They can be reused and, if source code is required and for event handler methods, they can connect to existing controllers of the "owning" view
      • This means that one important characteristic of fragments is that they are independent of the model-view-controller (MVC) concept and can be used without using MVC
      • However, if fragments are used together with views and controllers, fragments can make use of them and integrate them neatly
      • For more information please read Reusing UI Parts: Fragments (part of link pasted above - what is a fragment)
  • Fragment loading issue seen when comparing older SAPUI5 version to SAPUI5 version 1.60.X and later
    • It appears there is a change in the way the SAPUI5 refers to the local SAPUI5 library
    • Previously the application may have used the below library versions in the code:

      ~~~~~~Example~~~~~~~
      src=" https://sapui5.hana.ondemand.com/1.46.7/resources/sap-ui-core.js ".

      Note: This type of technique also seen in SAP application running SAPUI5 version 1.28.X
      ~~~~~~~~end~~~~~~~~~

    • Post system SAPUI5 upgrade to a later version 1.60.X or later appears the system have changed the way the local library is now sourced or loaded in the system

      ~~~~Example Now~~~~~~
      as src="resources/sap-ui-core.js"
      ~~~~~~end~~~~~~~~~~
    • With this seen changes to the local library, the fragment is not loading inside IconTabbar UI element (sap.m.IconTabBar)
    • Why would the IconTabbar start to fail with respect to fragments and the newer SAPUI5 1.60.X or later versions?
