SAP Build work zone, SAPUI5 app, controller not executing

[SailiRBendale]

Hi Folks,

I need your expert advice for an issue that I am facing when I deployed a simple UI5 application to cloud foundry.

I have created a simple UI5 which has a button and a label element, on press of which a function is called which displays a MessageBox. 

In view controller, I have added a MessageBox in init, just to verify is init is being called.

When I run the app with no-flp and sandbox, it runs perfectly fine.

When I deployed the app to cf , it is working fine when I open the app from HTML5 applications(I added FLP config while creating project).

Now when i ran the same app on Build Work Zone, the View controller is not loaded. The message box in init as well as button event is not displayed.  I observed that when I inspect the app, the controllers are not loaded in sources tab.

I need your advice for this issue.

Is this in your BTP trial account ? I'm also facing same problem since last week in my BTP Trial account for my new apps deployed and tile created in the Workzone std edition. I first tried with CAP & UI5 project which didn't work, so then created only a UI5 project. However, my earlier deployed UI5 app to CF is still working. Also, since today in my trial subaccount in Singapore region (Azure) the Workzone Site content manager is not working !

i can see there are 2 component-preload.js files loaded in the runtime, however on making changes in above files ("ui5-deploy.yaml" and "package.json") still doesn't resolve the problem.

My concern is basic functionality like the button click event, routing doesn't work !

I don't know whether it is due to change in the syntax of function names e.g. for the OnInit() hook method there are changes in the controller files (App.controller.js , Component.js , and the view controller.js) is causing the problems. Because now I see the function names doesn't have keyword ": function" , it is just the function_name () e.g. init() { }

I encountered a similar issue. If the app is run directly on BTP: HTML5 Application, it works fine. However, if it's run on SAP Build Work Zone, the controller does not seem to function.

Same issue and this is happening only for new apps created ... not sure since when but since last week I'm facing this problem. Existing apps are working perfectly when executed on the Workzone !

We further analyzed the issue and found that when the app is executing in WorkZone, 2 component-preload.js files are loading (inspected the app). One file has proper data and other one has incomplete data.

In order to overcome this, we did 2 settings.

1. ui5-deply.yaml : added below section under builder

  componentPreload:

    excludes:

      - "testworkzone/controller/**"

2. change package.json build script

    "build": "ui5 build --config=ui5.yaml -a --clean-dest",

With these 2 settings, the app worked perfectly.

PS: I am using trial account , US East(VA).

Do let us know if you find an alternate work around for this.

Hi,

I was having this same issue but have solved it now.

It seems some SAP guy was playing around last week with the BAS Fiori Generator and added some bugs to the App Controller. We can tell because they added some sapui5 walkthrough code.

I performed the following fix and my app started to work

Regards.

Thanks a lot. your suggestion resolved the issue. Spot on 🙂

[SailiRBendale]

Hi @DiegoValdivia, i tried your solution and it worked, but when i reload the launchpad/workzone, its does not load the application, and i mean the ui does not render.

UPDATE : well it seems to work, i think somethings wrong with my app.

[manishmatte1753]

My fiori apps are getting same code in App js as the View1 controller...lol

[manishmatte1753]

Hi @SailiRBendale, i tried your solution and added the code in ui5-deploy.yaml and the script in build:cf, but this solution does not seem to work for me, please let me know if you found any other way to solve this issue. Thanks.

is your app working or not?

controller not loading means nothing.

the component-preload file may have everything.
