Well, it was, and surprising behaviour at that. It turns out that the field
handling routines (?) were trimming my allocated 20 byte buffer to the size
of the null-terminated string (9 bytes including null-terminator) upon
de-focusing the field.
So, on the second callback call to load the text cell, I set the dataSize
parameter to the originally-allocated size of 20 bytes and complaint is
made that the size is invalid.
So nice that this is discussed in the documentation! It means that I cannot
trust that the size of my buffer will not be changed.
Note that I'm not sure how this affects situations where you might have
more null-terminated strings following the one being edited (much like the
way the way the ToDo database is structured) - do the routines truncate all
the strings that follow the one being edited?
