Hi

Do you have one view or multi views. if you have multiple views then check the following.

1)double click on your application

2) Under References check whether Interface View is your first view

Hi Swathi,

Open Navigation Modeler. (Right click on your window, you will get option).

Is there any view? You have to embed your view into the window.

Left side, you can see icons.

Select first icon (embed a view).

Draw the view in the window.

If already views are available, check whether the first view is the default view or not in the viewu2019s properties.

Regards,

Siva
