APEX 4.2.2
A page has a Evaluate for every page view authorizaton scheme of the type Value of item in Expression 1 = Expression 2 with Expression 1=G_ITEM and Expression 2=1. G_ITEM is set using a Before-Header application computation conditioned to fire when G_ITEM is null.
What I see is that the authorization scheme always returns false and the page is not rendered. Inspecting wwv_flow_data shows that G_ITEM is not there. So it would appear that the authorization scheme is evaluated before the application computation and since it returns false, the engine stops.
Does that sound right? Is this order of evaluation of components documented anywhere? There is a Utilities > Page Events screen but that doesn't include Authorization schemes.
Thanks
