Yes, I too think that validating user entries is one of rev's
weaknesses. However, artificially increasing the problem by not using
the fields as data source seems a bit strange to me, especially with
your reasoning.
How are these two lines completely different in their horribility?
put field 1 of card 1 into x
put the field1oncard1 of this stack into x
If you're really that much into customprops, you can put the fields
into them when you leave the card. or with a send in time message, or
on mousemove, or ...
More likely is that i didn't understand the problem you have correctly,
so maybe you should explain it in a different way.

Hi,
I asked about this problem ages ago, but didn't get a response, so I'm
asking again as it's just come up again!
I am running on a Mac. If the user fills in a field and then tabs out
of the field, either a closeField or exitField message is sent to the
field. All well and good. However, if the user clicks on a button,
nether messages are sent!
This is supposedly normal behavior since from the docs:
"If the lookAndFeel property is set to "Macintosh", the closeField
message is generally not sent when another control (such as a button)
is clicked. This is because clicked buttons do not receive the focus
on Mac OS systems, and therefore the selection remains active."
(incidentally, in this case the "lookAndFeel" and feel property is set
to "Appearance Manager", so according to the above it should still
send the message(s).)
This effectively means that it\s impossible to ensure that a field is
valid using these messages, so what's the use of having them or am I
missing something.
I want to let the user enter a number of fields and then when the user
clicks the button, I check to see if they are valid and if not put if
an error message. The problem is that the three field must be examined
together, so I'd like to be able to store the contents of each field
in a custom property of the stack and then check them in the mouseUp
handler of the button. I can't really access the fields directly (as
is put field "XXX" into whatever) since the check may be run on a
different card and it's really horrible to access fields like that.
Any ideas or suggestions would be greatly appreciated!
All the Best
Dave
