OK, thank you David, I can explain your
File > Validation errors, but not sure it explains Joel's.
To understand the problem you must understand how
Media records are associated with their host link.
The following explanation focusses of the
Media tab of an
Individual Property Box, but applies everywhere
Media can be linked such as in
Citations, on
Facts, etc.
Consider the
Media tab
Edit Media dialogue options to
Link to Face,
Exclude from Diagrams,
Exclude from Reports,
Use Note as Caption, and the adjacent note text.
Those details are NOT saved in the
Individual record, where it holds the link to the
Media record.
They are saved in the
Media record itself and shown on the
Links tab of its
Property Box in
Note &
Flags, etc.

So how does the
Media record know which of those settings apply to which host
Individual link?
GEDCOM does not allow a reverse link from
Media record to host record, so
FH invented one called
_ASID.
The
Media record and the host
Individual link have the same
_ASID number to associate the settings.
If you inspect the
GEDCOM file you will find them very easily, but
FH hides them even on the
All tab.
Code: Select all
1 NOTE 1879 Group Photo
2 _ASID 1
2 _AREA {154,46,243,127}
2 _EXCL ALL
2 _CAPT Y
1 NOTE
2 _ASID 2
2 _AREA {132,361,215,427}
1 NOTE
2 _ASID 3
2 _AREA {112,140,203,217}
When
David copies & pastes the
Citation with linked
Media, any
_ASID numbers go with the copy.
So now
two host record links have the
same _ASID number and the
Media record does not know which link to apply those settings to, and that is why
File > Validate reports an error.
To
fix the error, the
_ASID number is arbitrarily removed from one of the host links, which may be the wrong one.
( Note that no
_ASID entry against a host link is perfectly OK when only the default settings apply. )
Thus the associated settings may migrate from one host link to the other, which is not a perfect
fix.
However, you won't notice there is a problem if only the default settings apply.
What I cannot explain is why the
_ASID numbers are getting upset in Joel's case, unless he is copy & pasting
Citations but omitted to mention that.
