sap.m.splitapp - back navigation and setMode issue

Hi,

I am implementing a app using sap.m.splitApp .

in that i have setMode() of splitApp to setMode(sap.m.SplitAppMode.HideMode).

at the same time for the details page i made nav button true.

in the above case the setMode functionality is not working. when i comment the nav button false in page then the setMode Functionality is working.

is there anything as such that either navButton or SetMode() for splitApp any one should work or am i missing any setting changes.

Regards,

Santosh.
