From one viewpoint to another via a third viewpoint

Question

Hi!
I need help to make a function/script, on a button, that takes me from one viewpoint to another via a third viewpoint.
I want it to be like this:
When I push a button I want to change from view1 to view2 but before the camera goes to view2 it will go to view3, wait 1 second and then continue to view2.
I have this function for changing views, which works fine:
b var ViewExterior = function(viewname)
b {var context3D = getAnnots3D(0)[0].context3D;
b context3D.viewManager.goToView(viewname);}
On the buttons I have:
b ViewExterior = (view1); (or view2)
I have tried with some delay function like:
b function Delay(milliseconds)
b {var date = new Date();
b var curDate = null;
b do { curDate = new Date();}
b while(curDate-date < milliseconds);}
and on the buttons:
b ViewExterior = (view3);
b callMy3DFunction = getAnnots3D(0)[0].context3D.Delay(1000);
b ViewExterior = (view2); (or view1)
What happens is that the program waits for 1 seconds, without going to view3, and then moves on to view2 (or view1).
Any help on this would be helpful.
With regards,

Sorry about the delay.
