Unfortunately, yes it does.
However, if your data is value comparable, eg. the point (1,1) is the
same place in both datasets,
you can just override the data with the real CS into XY-M.

It is actually the other way around. I want to transform the real CS into
XY-M. Does the same count for this situation ?

Transforming between XY-M and a real CS is not technically possible; the
previous version must have been "guessing" that the XY-M dataset was in
the
same projection as the other datasets.
My bet is the change from PROJ.4 to Mentor as the underlying CS library
makes this a bit stricter, requiring you to manually specify the CS for
the
arbitrary data before attempting to transform it (or not).

Hello,
I have upgraded my MGOS 2.0.1 towards 2.1 and encountered following
problem:
- I have a map which has the X-YM coordinate system
- adding layers which refer to a featuresource with X-YM coordinate
system
works fine
- adding layers with coordinate system Belgian Lambert 72 causes
following
error message:
Error: Failed to stylize layer: RPA
The coordinate system initialization failed.
Could not initialize the geodetic transformation.
When overriding the coordinate system it works fine, but in previous
versions transformation took place automatically. Is this a change in
behavour or a problem with the transformation between the coordinate
systems
?
Thanks in advance.
