Call Controller Function from Handler Press Event

[Former Member]

Hi,

I have this code:

var oItem = new sap.m.ObjectListItem({
     id: "mainListItem",
     //press: "onSelectionChange",
     press: function(oEvent){
     this.onSelectionChange(oEvent);
     },
     type: "Active",
     title: "{Description}",
     number: "{Activity}",
});

But de application displays this error:

Master.controller.js:47 Uncaught TypeError: this.onSelectionChange is not a function

I used the code press: "onSelectionChange",but display this error:

sap-ui-core.js:143 Uncaught TypeError: I.fFunction.call is not a function

The onSelectionChange method exits in the View controller (BaseController). The application is a template of SAP Fiori Master / Detail 1.28.

Best regards,

Johnny

Hi Johnny,

before your initialize your Item, try:

self = this;

and than IN your initialize:

1. var oItem = new sap.m.ObjectListItem({ 
2.      id: "mainListItem", 
3.      //press: "onSelectionChange", 
4.      press: function(oEvent){ 
5.      self.onSelectionChange(oEvent); 
6.      }, 
7.      type: "Active", 
8.      title: "{Description}", 
9.      number: "{Activity}", 
10. });

Hello Jonny,

Where you have written this code?

the declaration part of columnlistitem is written  in View or Controller?

move press function logic  to controller like press: [ oController.handlePress , oController ] ,

or

try changing this.onSelectionChange(oEvent); to this.getController().onSelectionChange(oEvent);
