SAPUI5 Dialog - Uncaught TypeError: Cannot read property 'render' of undefined

[former_member190882]

Hi All,

I am trying to use simple message Dialog Box in my application and unfortunately landing into the following error.

Error: Uncaught TypeError: Cannot read property 'render' of undefined

when I try to open the dialog box using confirmDialog.open();. My code goes as follows.

var confirmDialog = new sap.m.Dialog(
  {

  title : "Confirm Reject",
  type : sap.m.DialogType.Message,
  content : [new Text({ text: 'Are you sure you want to reject the resoures?' }),], 
  beginButton : new sap.m.Button(
  {
  text : "YES", 
  tap : [
  function(oEvent) {
  yesOnNo = "YES";
  confirmDialog.close();
  }, this ],
  press : [
  function(oEvent) {
  yesOnNo = "YES";
  confirmDialog.close();
  }, this ]
  }), 
  endButton : new sap.m.Button(
  {
  text : "NO", 
  tap : [
  function(oEvent) {
   yesOnNo = "NO";
  confirmDialog.close();
  return;
  }, this ],
  press : [
  function(oEvent) {
  yesOnNo = "NO";
  confirmDialog.close();
  return;
  }, this ]
  }), 
  afterClose : [ function(oEvent) {
   confirmDialog.destroy();
  }, this ]
  });

  confirmDialog.open();

Please help me fix the issue.

Thanks

Hi Maruthi,

For Validation, why are you using a Dialog? Instead you can use sap.m.MessageBox.confirm.

Check this sample - Validation Sample

Hi,

I just stumbled about this issue and would like to share the solution that allows using the dialog:

In line 5 you create a new text element but you don't use the correct path.

As you do in line 1 with the dialog, you also have to instantiate the text object by using

new sap.m.Text.
