After using the Orienter on a line the attributes that are 'end sensitive' are no longer in the correct fields because of the flip. I used to use AttributeCopier (v2)
which did a fine job. But an "upgrade" has broken the swap, overwriting
so fields. I used to just not upgrade, but now the workbench just
crashes. I cannot create a new workbench with the old AttributeCopier so I am stuck with a kludge using a whole lot of temporary variables unless there is a more elegant solution. Is there?

Just to be clear, I need to do this:

Source Target

LTO RFR

LFR RTO

RTO LFR

RFR LTO

etc
for every "end sensitive" attribute. (You will remember that not only
do you have to reverse the data values, but it has to be mirrored as
well when a flip is done because left and right are also swapped.)

Preferably I would like AttributeCopier to revert to the original behaviour.

Not exactly sure I understand what you're trying to do, but would a TopologyBuilder after the Orienter work for you?

Kim is dealing with street segments with house number ranges and side parity, when flipping a segment direction the attribute values need to change ends and left/right parity.

 

 

The current behaviour of the transformer of altering the attributes one line at a time, rather than the transformer as a whole, matches the way the rest of the transformers work, so I doubt you'll see a reversion to the previous functionality.

 

 

Storing temporary attributes may seem kludgy, but it really only adds two transformers.

 

BulkAttributeRenamer and BulkAttributeRemover.

 

 

If performance is an issue and you have lots of end sensitive attributes, you could even only bulk rename half the attributes (either all the Froms, or all the Lefts, etc), as long as the AttributeCopier is setup in the right order. You could alternately replace the AttributeCopier with an AttributeCreator or AttributeManager.
