i want to show the help dialogue popup in Home, Master, Details pages.,

for that i placed the help button in 3 respective views  Header

.

when the user clicks on help it show dialogue popup and user can select the value , i am trying to implement this .

For help dialogue i have created  fragment.

please Find the following code:

Home View.XML:

  onInit: function()

xmlfragment("sap.ui5.myapp.fragments.HelpDialog", this);

this.getView().addDependent(this.HelpDialog);

   };

Home Controller.JS

  onDialogPress: function() {

this.HelpDialog.open();

  },

onHelpSelect: function(oEvent) {

  var selectedItem = oEvent.getParameters().listItem;

  var HelpType = selectedItem.data("HelpType");

My logic is here

}

},

closeAlert: function(oEvent) {

oEvent.getSource().getParent().close();

  }

This logic is working fine for  home view i am able to click help icon and choose the value without any error.

when i click to navigate from home view to  master view i am getting the error like Uncaught Error: Error: adding element with duplicate id 'HelpType' - when i click to navigate second time its working fine

i need to implement the same  functionality to master and detail controller.

how can i solve this issue please help me the same.any sample code would be appreciate.

Thanks
Srithar.
