Hooks add_new - replace

[horst]

current situation is as follows:

With my MP3-DB I create extended page-objects that have some additional Properties and tweaked Children.

Now I've thought if it would be better to use the 'real' $page variable for that.

Extending it with some Properties could be done like explained in the Hooks-API-Doc: http://processwire.com/api/hooks/#add_new_property

But, I need to tweak the $page->children and $page->childNum.

Is there any chance to do that?

------------

why do i want this to have:

if one is, for example on a album-page, the album-page has no children, because the DB-Structure has sibling branches for albums and songs. But human logic says an album must have children (the songs)

Why not $albums and $album->songs?

Why not $albums and $album->songs?

Oh! - Ok, why not!
