Retrieving any FO object knowing its ID inside the Layout Manager
when constructing the content in the Layout Manager, I can access properties
of the processed FO object, but I'd like to access properties of an
arbitrary FO object knowing its ID.
Inside the Layout Manager I can only retrieve the PageViewport for the
specific ID, but this object doesn't tell much about the FO object itself.
PageViewport pageViewport = getPSLM().getFirstPVWithID(id);
I need to populate the index-class property of that target object. Are there
more efficient ways?
