Description

Hi,

I decided to try upgrading an app from t54-beta-26 to the latest public beta. Most things seem to work, but I noticed changed behavior with onActivate methods in some of our classes.

We have a base page with the following:

@OnEvent( ACTIVATE )
void activate( EventContext ec)

and an extending page with:

@OnEvent( ACTIVATE )
Object activate( EventContext ec )

In beta-26 (and before) the methods are called in the following order:
1) Base activate
2) Extending page activate

In beta-33 and newer only the Base activate is called.

I'm attaching a sample project where one can play with the versions and see the differences in the console when requesting the index page.

Also when creating the sample project i noticed that PageLink (to login in Layout.tml) fails if Login page is missing in beta-33 while it has no problem with pointing to a deleted page in beta-36.
