Summary0007110: Session with selected midi notes in 5.4.320 crashes when opened with 5.4
DescriptionI know that we don't guarantee backwards Session file compatibility but if this is easy enough to fix/revert/add compatibility, I think we should do so.

It looks like this issue was introduced recently with commit 9698f16a
TagsNo tags attached.

Can you get a backtrace? Is it as simple as

Selection::set_state ()
{
  ...
  XMLProperty const * prop_id = (*ci)->property (X_("id"));
  Evoral::event_id_t id = atoi(prop_id->value());
  ...
}

and prop_id is NULL when loading a 5.4.0 session?

Potential fix in 5.4-334-g6794a83

since "id" not a PBD::ID but an Evoral::event_id_t I think we should change the identifier-name and not re-use "id" in the XML.

Sorry, backtrace from 5.4 build uploaded.

I'll test potential fix now.

Oh, that's the other way 'round :) I've fixed backwards compat: A session saved in 5.4.0 w/selection -> open in 5.4-git.

You want forward compatibility :(

I agree about not using "id" as the identifier name, perhaps "note-id" or "event-id" (unless that may cause complications later on)

In this case I would prefer if a Session with midi notes selected and saved in 5.5 doesn't crash when opened in 5.4.

We could strictly stick to a no "forward" compatiblity policy but I think this may annoy people if they are sharing and working on Sessions between 5.5 and 5.4 versions.

Even if this doesn't get fixed, I thought it necessary to at least report the issue.

Changing the top-level identifier ("MIDINote") to something else would work.
In that case selection is simply lost when going between 5.4 and upcoming 5.5

Losing selection state when opening a Session in an earlier program version *is* totally acceptable IMO.

Tested with c16eb83f applied. Should be resolved as of nightly build >= 5.4.341

Now opening a Session created in version >= 5.4.341 with 5.4 only selection information is lost, no crash.
