[Note : This blog would be equally relevant for Lumira Designer 2.x as well as the same migration from SAP UI5 commons controls to sap.m would be required . This blog would focus from the perspective of Lumira discovery.]

With the technology migration from Lumira 1.x to 2.0 , we had taken a conscious call where-in we moved away from supporting the SAP UI5  (including Open UI5 as we) commons library  controls to the sap.m library controls  and its standards . Now, what it means to our developers is if they have developed any visualisation or data access extensions or components using the SAP UI5 commons library for SAP Lumira , then would have to migrate to the sap.m ( controls . Using  rest of  web  friendly technologies like the HTML , CSS , Javascripts still remains the same and you can continue using it as long as you were following the guidelines suggested for developing 1.x extensions.

An example for how the library controls  between SAP UI5 commons and sap.m would look like is mentioned in the below sample table :


In this blog instead of being theoretical , I will try my best to provide you with a sample data access extension which was built for Lumira Desktop 1.x in SAP UI5 commons library  and we will understand how to move to 2.0 to make it UP and Running.

Instead of just mentioning the the technology changes , I will take the example of an extension which is already available in GitHub : Google chrome network logs data access extension :

The extension is available in the below link which you can download(As of today by this time the blog publishes, the extension is still supported for 1.x line and needs to be upgraded.)

The  UI elements for the current data access extension was built using SAP UI5 commons library and what we would understand from here in this blog is  , how we migrate to SAP UI5 commons library to sap.m library.

At first, i have downloaded the extension available from the GitHub and then imported into the Eclipse IDE.

In the current Chrome network logs extension , the UI is built using the SAP UI5 commons UI controls and the  main UI file which is available as part of the file

ChromeLogsExtensionDialogController.js .

In the below screenshots , you can find on your left side of the code is the 1.x  supported old UI5 commons controls where-as on your right side of the screen , you can  find the changed sap.m controls code.







The complete   changed code with sap.m UI controls is given below :

Rest of the code remains unchanged , compile and  build and execute in the Lumira 2.0 Discovery and you should be seeing new the UI as below.

Input the required details and acquire the dataset.
