Jan,
Thanks. It looks like it sends the revUpdateCellValue message whenever
a cell changes (like when pressing tab or return) not just when the
value changes. Unfortunately, without the pOldText value I can't tell
if it changed or not.
Maybe you were thinking of a different message that only sends when
the value changes? If not, I'll report the pOldText value missing as a
bug.

How do I tell when the contents of a table field

It doesn't seem to generate a closeField message
which is what I
really want.
Recipe (Rev 3 IDE. Mac OS X 10.5.5)
1. Create a table field
2. Set the script to:
on closeField
put "Close Field"
end closeField
on exitField
put "Exit field"
end exitField
3. Edit the contents of the field or even click off
the field. Nothing
is put in the message box.

Hi Bill,
The tricky part is that the table field is not the
target of the closeField message - instead, it's sent
to the temporary field that is created as a 'cell
editor' in the 'revTable' frontscript.
What makes this even more complicated, is that this
'cell editor' field is actually deleted by that
frontscript before the 'closeField' is passed on to
the message path.
However, not all is lost, as the 'revTable'
frontscript will actually send out an undocumented
message if a cell has changed:
revUpdateCellValue
pObject,pXcell,pYcell,pOldText,pNewText
Looking at the frontscript, I wouldn't count on the
'pOldText' parameter though - it looks like that got
lost in one of the changes to the frontscript.
HTH,
Jan Schenkel.
