@jruiz : Guess you talk about expressions (instead of reference)...

@Kunda1 : actually I'm a bit hesitating. Yaw/Pitch/Roll (YPR) was originally listed in the forum thread going with 0003981 that I set as dup. But they have been removed because DeepSOIC (truly) stated that they are a big beast because they don't match any exposed property. So if YPR support expressions, user may first use them, then bind other (conflicting) expressions in the Angle+Axis properties in the Property Editor.
This is also probably an issue by itself that expressions entered in the YPR aren't visible in the Property Editor.
Maybe what could be fair would be to replace the dup of this ticket with a "related" link (as there is no real overlap), and take time to carefully think what to do here.

@openBrain thank you for the comprehensive answer. I think this merits a forum thread for further discussion on how to move forward. Do you mind doing that? ;)

@Kunda1 I need to clarify something on the original discussion then I'll do accordingly. ;)

@Kunda1 : My understanding of the problem was actually a bit erroneous. I corrected my note above. Do you think a thread is still needed ?

This is because there are actually 2 dialogs to edit attachments of objects:

- one is src/Mod/Part/Gui/TaskAttacher.ui and this has the ExpressionEngine f(x) icon. This is the one coming with the Part WB
- the other is src/Mod/Part/AttachmentEditor/TaskAttachmentEditor.ui and this one has not. This comes with the PartDesign WB

visually they're identical, and functionally they're similar but slightly different. This is actually the exact same problem as issue 0004258, because these confusions can cause crashes in some circumstances.

EDIT: when a datum is created then src/Mod/Part/AttachmentEditor/TaskAttachmentEditor.ui is called, therefore the AttachmentOffset fields don't have the f(x) buttons. When the datum has been created and later its Attachment property is edited from the property panel (clicking on the tiny button in the MapMode field) then src/Mod/Part/Gui/TaskAttacher.ui is called and this one does have the f(x) buttons.
