view not shows in the navigation manager at first instance

I am using navigation manager to show a set of views.

  1. I have a view which has vertical component group and when I click on the button to show another view using the following code.


It seems that the view is not displayed at once but when I make the view smaller by dragging the positions of the window it seems to show me the view correctly.

Any thoughts on this as to why it is not shown but when I resize it with the mouse it shows

It is more sort of a rendering issue
