Hi,
Take a look at getGUID in the Community Commons module on the App Store. It will give you the ID you need.
Hope this helps,
Rob
In your case instead of a page parameter, you can set a microflow as a datasource for your dataview and create the object in the datasource microflow. Setting the page url on a page without a page parameter will not require an id.
If you want to pass the object as a page parameter instead, you can use the deeplink module.
