Handler for Button not called in adaptation

[Boguslaw]

Hello everybody,

I try to extend a standard App "Create maintenance request" (F1511A). I have added a Fragment with button and the button is available:

My Fragment look like this:

<core:FragmentDefinition xmlns:core='sap.ui.core' xmlns='sap.m'>
    <Button id='LorCapBtn' text="LorCap" press='extension.customer.create.notif.variant.onLorCapPress'/> 
</core:FragmentDefinition>

The controller:

sap.ui.define(
    [
        'sap/ui/core/mvc/ControllerExtension'
        ,'sap/m/MessageBox'
        // ,'sap/ui/core/mvc/OverrideExecution'
    ],
    function (
        ControllerExtension
        ,MessageBox
        // ,OverrideExecution
    ) {
        'use strict';
        return ControllerExtension.extend("customer.create.notif.variant.MainCntrlExt", {
            onLorCapPress : function(oEvent){
                console.log("onLorCapPress called");
                MessageBox.success("Hello");
            },
});
    }
);

When I press the button nothing happened (no massege box, no message in console).

Do you know what is the problem? What have to be done to run my code?

Regards,

Boguslaw

Probably you are missing the . before the extension,  MainCntrlExt is also missed

<core:FragmentDefinition xmlns:core='sap.ui.core' xmlns='sap.m'>
    <Button id='LorCapBtn' text="LorCap" press='.extension.customer.create.notif.variant.MainCntrlExt.onLorCapPress'/> 
</core:FragmentDefinition>

Hi Junwu, thx for your hint - the dot was missing, the second part the was missing as well, was the cntroller name. The correct path to my handler is: 

<core:FragmentDefinition xmlns:core='sap.ui.core' xmlns='sap.m'>
    <Button id='LorCapBtn' text="LorCap" press='.extension.customer.create.notif.variant.MainCntrlExt.onLorCapPress'/> 
</core:FragmentDefinition>

I think your namespace in the button is wrong, you're missing MainCntrlExt

Try:

.extension.customer.create.notif.variant.MainCntrlExt.onLorCapPress

Oh, I'm on mobile and did not see the answer, good to know I got the right answer 😄

<core:FragmentDefinition xmlns:core='sap.ui.core' xmlns='sap.m'>
    <Button id='LorCapBtn' text="LorCap" press='.onLorCapPress'/> 
</core:FragmentDefinition>

have you tried this?

[Boguslaw]

Hi Fabio, thx for your answer. I have just tried your proposal - it does'n work. In SAP Fioti Toll user guide is decribed that the function name for press event should have a prefix ".extension.<controller extension namespace>."

Please share the manifest where extensions are declared as well
