T5 OnException or page redirection fails when using Grid inPlace

[Daniel Jue <te...@gmail.com>]

Using T5.0.14

Just found this after a couple hours.

Case:

User Logs on login page, user ASO created
Page with Grid is rendered, using inPlace, all is well.
User session times out, or logs out in another window. (doesn't matter
which)
User clicks on a sort button on the Grid, and the page hosting the grid
requires the user session.

We expect that the page with a grid would allow redirection to the login
page, but when using inPlace, we get a " Page must be specified before root
render command." error when an onActivate or onException page redirection
occurs.

We actually get the same page, with no changes.

[DEBUG] BaseReportPage [ EXIT] onActivate
