Operating system: Windows-10-10.0.19043-SP0 64 Bits

Blender Version
Broken: version: 3.2.0 Beta, branch: master, commit date: 2022-05-24 13:22, hash: bc3dbf109c

Short description of error
Applying object Transforms on multi users is supposed to give you the option to turn the objects into single user objects and apply the transform. It works sometimes. Sometimes it works only for the active object and soemtimes it does not work at all and either does nothing at all or reports an error (Cannot apply to a multi user "nameOfObject" Aborting).

Exact steps for others to reproduce the error

create a cube and duplicate it a couple of times with linked object data ({key Alt D})
do the same with a monkey
(Optionally) scale the cubes and monkeys
select all objects so that "all the users of the multi-user data are part of the selection" (8621fdb10d)
apply scale
i now get an error message "can not apply to a multi user"

The problem is not clear.
Objects selected with the same Data are also updated accordingly.

If there is any unselected object with the same Data, a new data is created for the selected ones.

If you repeat this process with different selections you will naturally have more and more groups of different objects but with the same Data.

This report is unclear. Please give us more clear instructions on how to reproduce the bug.

Maybe I am misunderstanding how this feature is supposed to work.

I thought that it was supposed to work like this:

Select 3 objects sharing a single mesh data but different (for example) scales
Apply Scale
Now you have 3 objects with three different meshes datas

Is this not correct?

Has it worked like this before?

It is a new feature in 3.2 so It has not worked like this before because it was not in Blender before.

I am not sure how this feature is supposed to work but I thought it worked the way as described above.

However, after reading the following I am still not 100% sure what it is supposed to do exactly but I still think there is a bug. Or the description in the commit is imprecise.
https://developer.blender.org/rB8621fdb10dc4

The commit states that:
"However in some particular cases it is possible to apply them:
If all the users of the multi-user data are part of the selection."

Try the following:

create a cube and duplicate it a couple of times with linked object data (alt - d)
do the same with a monkey
scale the cubes and monkeys
select all objects so that "all the users of the multi-user data are part of the selection"
apply scale
i now get an error message "can not apply to a multi user"

This is the previous behavior, before the multi-user feature was implemented.

Looking at the code, it's clear that the apply to multi-users feature only works if all selected objects have the same Date. (See {https://developer.blender.org/diffusion/B/browse/master/source/blender/editors/object/object_transform.cc$623})

Perhaps the feature could be improved, or the error message more descriptive. However, this is not a bug.

So thanks for the report, but the issue reported here is a request for modified/improved behavior and not a bug in current behavior. Closing as this bug tracker is only for bugs and errors.

Ok, I guess I misunderstood the description of the feature in the release notes and the commit.
