Re: Grouper - Formatter file loading issue

Thanks for your reply. I tried with below approach:

In my Master.cotroller.js. i have placed below code:

jQuery.sap.declare("sap.ui5.sflight.util.Grouper");

sap.ui.controller("sap.ui5.sflight.zui5_sflight_book.Master", {

  handleGroup : function(evt) {

  // compute sorters

  var sorters = [];

  var item = evt.getParameter("selectedItem");

  var key = (item) ? item.getKey() : null;

  if ("Year" === key) {

  var grouper = sap.ui5.sflight.util.Grouper[key]; (##### here is the issue)

  sorters.push(new sap.ui.model.Sorter(key, true, grouper));

  }

  // update binding

  var list = this.getView().byId("list");

  var oBinding = list.getBinding("items");

  oBinding.sort(sorters);

  },

});

In my master.view.xml the concerned call is:

<footer>

  <Bar>

  <contentRight>

  <Select id="groupSelect" change="handleGroup" icon="sap-icon://group-2"

  type="IconOnly" selectedKey="None" autoAdjustWidth="true">

  <core:Item key="None" text="None" />

  <core:Item key="Year" text="Year" />

  <!-- <core:Item key="Year1" text="Year1" /> -->

  </Select>

  </contentRight>

  </Bar>

  </footer>

so the "key" is Year which I am passing to my grouper.js. Now the grouper.js content is as below:

jQuery.sap.declare("sap.ui5.sflight.util.Grouper");

sap.ui5.sflight.util.Grouper = {

  bundle : null, // somebody has to set this

  Year : function(oContext) {

  var Year = oContext.getProperty("Year");

  var key = null, text = null;

  if (Year = 2015) {

  key = "Y15";

  text = "Year 2015 ";

  } else if (Year = 2016) {

  key = "Y16";

  text = "Year 2016 ";

  }

  return {

  key : key,

  text : text

  };

  }

}

But system is not able to find the grouper.js as it is not getting loaded. Please advice how to solve this issue.

Thanks, SL
