Hi Paul,
I believe you've found a bug! The red drop target should always tell
users where the item will fall--when it doesn't that's definitely a
bug. In http://build.fluidproject.org/fluid/sample-code/reorderer/image-reorderer/image-reorderer.html
, I verified that if I hold an image too far to the right *only when
moving it downwards* (just like you found) it doesn't drop where the
red drop target indicates it will.
This seems like a pretty important bug -- is it something we should
try to fix before the release?
Cheers,
Allison

Hi Daphne,
I tried to perform the tasks in the Round 1 protocol, and I must
say I completely failed at task 2. Well, not completely, but it
took me many minutes to figure out how to perform it reliably. I'm
sure that no tester would have given me enough time.
If I have the fruit images in two rows, it is really easy to move
any of the second row images to the centre of the first. If there
are seven images in Row 1, I simply select any second row image and
place the target after Row 1, Image 3. It doesn't matter how the
avatar is positioned -- if the target is to the right of Image 3, my
selection drops into the middle. I also notice that the target is a
good indicator of which images the one being moved will fall
between. That is, if the target is between the blackberry and
cherry, that's where the one I'm moving ends up -- between the
blackberry and the cherry.
So far, so good. My success at moving images from Row 2 to Row 1 is
so confidence-inspiring that I decide to move an image from Row 1
into Row 2. Should sort of work the same, shouldn't it? (Now I know
that it won't quite be the same, because I know that I'm really
operating on a one dimensional list, not a grid. So things will
rearrange themselves to fill gaps, but I let my sense of having
learned something in the first trial carry over.)
Now what happens? Well first of all, I find that the position of the
target causes rather different behaviour. If I place the avatar
over the image currently in the centre of Row 2, it doesn't seem to
matter which side of it the target is on. The current centre image
moves to the left and the one I'm moving takes the centre position.
So, I sort of know how to get my image into the centre, but I'm
totally confused about how to get my image between two others. The
"between-ness" rule I had inferred from the previous trial doesn't
work any more.
So I experiment a bit an suddenly find that things aren't dropping
where I expect. I'm totally confused until I notice that the
relative positions of the avatar and the target are important with
this kind of move (Row 1 to Row 2). If the centre of the avatar is
a bit to the left of the target, the image ends up on the left side,
and if it's a little bit to the right, the image ends up on the
right side. The rule I now infer is "the image my avatar is
hovering over will scoot to the left, and my image will replace it
-- the position of the target doesn't really matter. This is a lot
different from "a gap will open up where the target is now, and my
image will go in between".
So I end up with two rules:
When I move things up, the position of the target tells me where
they will fall.
When I move things down the position of the avatar tells me where
they will fall.
I'd be embarrassed to tell you how long it took me to figure this
out. I hope your test subjects are able to catch on a bit quicker
than me.
One other thing I noticed which you may want to control for while
testing. If you resize the window so that the rows have an even
number of images, the "middle" is less well-defined than if you have
an odd number..
Regards,
Paul
