I have a view, using sap.ui.table which has an editable vkorg column , these column is bound to a myModel4 model

XML view:

<u:Table rows="{myModel4>/BacklogHeaderSet}" busy="false" id="table40" rowMode="Interactive" cellClick="onCellClick" >
  <u:Column width="11rem" sortProperty="Vkorg" filterProperty="Vkorg">
    <Label text="Vkorg."/> <!-- The vkorg column -->
    <u:template>
      <Input xmlns="sap.m" value="{myModel4>Vkorg}" id="input41" valueLiveUpdate="true" liveChange="onChange" submit="onSubmit"/>
    </u:template>
  </u:Column>

myModel4 is not created by default. There is a bind button when I press it will create the myModel4 model dynamically:

 onBind: function() {
    var oModel = new sap.ui.model.odata.v2.ODataModel("/sap/opu/odata/sap/ZBAJUSZ_ODATA_BACKLOG_SRV/", {
        defaultOperationMode: sap.ui.model.odata.OperationMode.Client
    });
    oModel.setDefaultBindingMode(sap.ui.model.BindingMode.TwoWay);
    var myTable = this.getView().byId("table40");
    myTable.setBusy(true);
    oModel.read("/BacklogHeaderSet", {
        success: function(response) {
            myTable.setBusy(false);
        }.bind(this),
        error: function() {
            myTable.setBusy(false);
        }
    });
    this.getView().setModel(oModel, "myModel4");
},

Running app screenshot

The model has a 2 way binding mode, and the input cell has valueLiveUpdate="true". My problem is that when I change the value of the Vkorg cell, the myModel4 value is not updated. It always contains the old value.

What can be the problem? Thanks for the help.

I tried to check the data after Submit and change event of the input field, but myModel4 not updated automatically,

I put a button on the screen, and on the press event I get the model values and write it into the console:

onLoopSO: function () { //Looping all entries of the table (binded to myModel4)
var oModel = this.getView().getModel("myModel4");
var oData = oModel.oData;
var oRecord;
var oTable = Object.getOwnPropertyNames(oData);
for (var i = 0; i < oTable.length; i++) {
oRecord = oTable[i];
console.log(oData[oRecord].Vbeln, oData[oRecord].Posnr, oData[oRecord].Vkorg);
}
},

  • How do you check that your model contains the old/new values? Commented Jan 2 at 9:03
  • I put a button on the screen, and on the press event I get the model values and write it into the console. I added the code into the question. Interesting, if I update the model VKORG value manually in the LiveChange event, then the model has the correct value. Commented Jan 9 at 9:12
  • It's because your model is a sap.ui.model.odata.v2.ODataModel (a server model). After change you need to submit change to backend. If you update directly data in your model , you can call oModel.submitChanges(); tu effectively do the changes Commented Jan 15 at 22:21
  • Are you sure about this? I mean, is it the correct behavior that you have a model and doesn't matter what you change on the screen, the model doesn't reflect the changes? Commented Jan 16 at 16:03
