Hello,
I have created a fiori element list report based on a CDS view.
When the user selects an entry in the list and clicks on a button ‘display text’, I want to retrieve a long text from the DB and display it in a popup.
I have added a custom button on the list report.
I have implemented the method DEDUCTIONITEMTEX_GET_ENTITYin DPC_EXT
I have created the following dialog fragment:

And in the list report controller extension I have implemented the below:
onClickTextItem: function (oEvent) {
// GET ITEM TEXT FOR DISPLAY AND/OR UPDATE
// Popup to display a text item. The user will select one item.
// By pressing button 'save' a request will be sent to the backend to modify/create the text
//get selected item of the list
var oTable = oEvent.getSource().getParent().getParent().getTable();
var aContext = this.extensionAPI.getSelectedContexts(oTable);
if (aContext.length === 0 ) { sap.m.MessageBox.error("Please, select at least one item", {}); //message select at least one item
} else {
//logic to get the selected item
…………
var mParameters = { BckDoc: DocNum,
BckItem: ItemNum };
// dialog fragment
if (!this.byId("valTexttDialog")) {
// load XML fragment
this.oDialog = sap.ui.xmlfragment("xxx.rev_deductions.fragments.textItems", this);
this.getView().addDependent(this.oDialog);
var oModel = this.getView().getModel();
var sPath = "/DeductionItemText";
// access form from the fragment by its ID
var oForm = sap.ui.getCore().byId("EditFormId");
oForm.setModel(oModel);
// Get text and fill form
oForm.bindElement(sPath, mParameters);
// open dialog
this.oDialog.open();
}
}
},
I have a problem to bind the elements of the simple form with the model. When I run the app I get the exception “Uncaught TypeError: Cannot read property 'indexOf' of undefined”.
I have done a similar development to display a list of items in a dialog fragment and used the bindAggregtion without any problem.
Do you have any idea how to solve the problem?
Thank you
Christophe
