Clear Popup Dialog content to open from another entry

Hi,

Please let me know how to clear the View Content of Popup Dialog without closing using the Popup close button. Without closing the Popup , If I try another item , it is giving duplicate id errors. After closing popup , without refreshing browser, same issues happening.

What is the correct event handler to place this.removeAllContent()

Please check sample code below.

if (step == "1") {

                var oDialog = new sap.ui.commons.Dialog({

                modal : true,

                height : "90%",

                width : "90%",

                // buttons : [ oBtnBack, oBtnNext, oBtnCancel ],

                content : [ oView ]

            });

            oDialog.open();

        }
