Page stack and navigating to the same page with other params

Hi everybody!

I’m new to ionic and I have a question regarding the navigation stack:

I have hierarchical product groups and show them on one page. At the moment I start with the root PG’s and when I’m clicking on an item I do a Nav.push to the same page with the productgroupid as parameter and all the subgroups are loaded properly.

But it seems that the new page is not added to the navigation stack. There is no “back button” avaliable on the second page. If I create one manually and do a Nav.Pop() I get an error.

So: Is there any possibility to force ionic to put this second page to the stack even its the same page class ?
