Fiori Elements: Controller Extension not loaded

[htammen]

Hi,

I have a Fiori Elements ListReport/ObjectPage app and want to extend the controller of the ObjectPage.

Hence I added this to the manifest.json

"sap.ui5": {
   ... 
   "extends": {
      "extensions": {
        "sap.ui.controllerExtensions": {
          "sap.suite.ui.generic.template.ObjectPage.view.Details": {
            "controllerName": "de.tammenit.portal.ui.stammdaten.ext.Custom"
          }
        }
      }
    }
   ...
}

In folder "webapp/ext" I created a file "Custom.controller.js" with this content

sap.ui.define([], function() {
  "use strict";
  return {
     onInit : function () {
          console.log("samples.components.ext.customer.CustomMain - onInit");
      },

      doSomething: function() {
          alert("this is a customer action");
      }
  }
});

When I run the application I would expect that my custom controller is merged into the ObjectPage.view.Details controller.

But my controller is not loaded and hence the onInit method is never called.

I also tried the "Controller Extension" approach described here: https://sapui5.hana.ondemand.com/#/topic/21515f09c0324218bb705b27407f5d61.html with no success.

Any suggestions?

Thanks Helmut

Could you tell us since which SAPUI5 version the approach failing? Or is it failing in all versions?
Other app devs seem to experience similar issues.

I don't know since when it is failing. I use the newest version 1.99.0

same issue with you, as mentioned in ui5 website, controller extension could be as a plain object which define by sap.ui.define(). but when i run my extension project, the extHookChangeFilterItems in original controller still remain null, never implemented, have you got the answer now? if yes, could you please guide me.

Hi soumyar ,

as I saw You recently faced this issue, please try as explained by Vladislav already. So try to define Your extension controller like this, with the "old" approach. In case this is an older WebIDE OData V2 template project this.getView().byId should work with the below controller definition.

sap.ui.controller("namespace.appId.ext.controller.ListReportExt", {

    /**
     * View initialization
     */
    onInit: function () {
        let smartTable = this.getView().byId("listReport");
        
        if (smartTable && smartTable.getMetadata().getName() === 'sap.ui.comp.smarttable.SmartTable') {
            
        }
    }
});

Best regards

Attila

Hi Attila, got my issue resolved with variable definition was at wrong place. This was causing the controller code not defined within the required format. Thank you, Soumya

Hi,

probably it is too late, but I have had a discussion with the colleague. He showed me that the controller extension might not work with typed components, and you have to use sap.ui.controller to extend the existing controller. You can give it a try (yes, I know that you asked this question in April).

Meanwhile, it seems that you can use typed components, but your controller should be created in a different way (using sap.ui.core.mvc.ControllerExtension): https://sapui5.hana.ondemand.com/sdk/#/topic/c264d66d6e3c4104818bc52c174a000c (this is an original help article, but it points to another chapter that you might find it helpful: https://sapui5.hana.ondemand.com/sdk/#/topic/21515f09c0324218bb705b27407f5d61.html)

Kind regards,
Vlad
