I like this technique, but there are lots of times when I've created
a button, given it a name and label, then down the road decided that
the label isn't exactly right and needs to be changed for clarity's

times in handlers, so it becomes a chore to rename the button. So you
would lose one of the main advantages of the capability of having the
name and the label be different.
Not so, and is in fact one of the reasons I like following the
pattern of
ensuring the label and the name are the same (which typically are
identical
to the MySQL column name I'm retrieving the data from). Should I
decide down
the track that the name, either in MySQL or Rev needs to change to
something
better, in Rev you simply open up the IDE Find and Replace (not the in
script Search). In most cases, because the original name is self
explanatory
it is highly likely that it is unique so a global Find and Replace
is OK,
but if you're way into a project and you discover you've just
created your
15th "Next" button and figure maybe some buttons should be named/
labeled
'Next Card', 'Next Page', 'Next Chapter', 'Next Week', etc etc, the
Find and
Replace does a great (but slow) job of identifying the actual
control or a
reference to it in a script.
Yes, if you had 15 Next buttons with 10s of references to each of
them in
scripts, changing them at a later date would be a pain, which of
course is
the reason for the 'best practice' to intentionally avoid the
generic 'Next'
and think of a 'descriptive' name; is it Next Job, Next Pay, Next
Dance, etc
etc. If you can be descriptive enough to avoid repetition then
changing
Well argued, Kay. (Yes, I do know about Find and Replace, but it is
often overridden by the lazyDeveloper flag. ;-) )
In fact, based on your argument I may add a new best practice item:
As much as possible, keep object names unique within a stack. It will
make finding and changing references to object names in scripts
easier, should it become necessary.
