Pre-loading activity differs in context at design and runtime

SA-7066

Summary



After upgrading from PRPC 6.2 to Pega 7.1.7, developer noticed that there is a different behavior for defer load activity on Tab Group.
With Pega 7.1.7, the application expects to find the activity in a different class.
But with PRPC 6.2 the expected class is one of the main section, instead now with Pega 7.1.7 application looks for the activity in the class of clipboard page defined as Page Context.


It seems, there is at least an issue with the modal dialog that allows to configure the layout properties. At design time the available activities listed are retrieved from the class of the main section, and not the class of the page context.

Steps to Reproduce



Upgrade from PRPC 6.2 to Pega 7.1.7 with defer load activity on TAB Group.

Resolution



1. Page Context value - When used "Use page defined by property"  
    Here one can provide property reference which holds the page name but not the page type property. 


2. The pre-load activity refers the section class and its hierarchy. The pre load activity is executed before the section renders, hence it does not know the page context defined, so it is the section defined class itself.
