Using BOR Object as Attribute In ABAP Class

[Stevens, Seth]

Yeah, not sure what the issue is here.  Everything is marked as public
and the binding editor can see the object and display all the correct
attributes; however, the binding syntax check throws the error when you
choose one of the attributes.  At this point I'll probably look for a
work around but will send out an update if I figure out the issue.

Thanks again...

Hi Seth,

You're on the right track, but missing the bit that the binding editor
won't instantiate the class. If you make the constant public (so the
binding editor can see it) and specify it as the initial value for your
attribute it should be happy. I think. Not sure how/why it's working in
one instance but not the other - see if you can expand the attribute in
a regular binding.

Regarding a user class, I still say go for it. It's easier to work with
and far more flexible and there's nothing stopping you from mixing and
matching. I often end up with BOR and classes for the same object.
Basically I take an opportunistic approach: if I need to spend any time
working with a BOR object then it's a good excuse to add the
functionality to a class instead (provided it's not a major effort).
Regarding maintaining two code streams - just mark the BOR method
obsolete. If it needs changing then do it the other way around:
incorporate the class into your BOR object as a private attribute,
change the code in the class and replace your BOR method code to call
the class method. Although BOR doesn't understand classes as components,
you can instantiate and use a class internally because it's standard
ABAP.

Cheers,
Mike
