sets the right edge of am before am has adjusted its size base on
its submorphs. Add the line marked above. Normally you would let
the alignment-style properties ripple down and up the tree and all
would be cool. Your insertion of manual positioning needed the
extra step.<br>

<pre wrap="">Here's a fun way to kill a few braincells. I've been tearing much hair out for the last couple of days trying to work this one out; why do my morphs not go where they ought?
Consider a morph with a submorph AlignmentMorph (I know, you don't need to use AlignmentMorphs so much now) that in turn contains two morphs. Set the alignmenmorph's right to the main morphs right-10. Open it; what do you expect? I'd expect to find the pair of morphs lined up near the main morphs right side.
Nah. Don't be silly.
Try out this code -
|m am|
m := Morph new color: Color white; extent: 200@100.
am := AlignmentMorph newRow
hResizing: #shrinkWrap;
vResizing: #shrinkWrap;
listDirection: #leftToRight;
color: Color transparent.
am addMorph: (Morph new color: Color red; extent: 37@51).
am addMorph: (Morph new color: Color blue; extent: 43@51).
m addMorph: am.
am right: m right -10.
am top: m top +2.
m openInWorld
Now change the listDirection: #leftToRight; to listDirection: #rightToLeft and see what happens. I think that is just plain wrong.
Better yet, add 'am right: m right -10.' after the openInWorld. Now it goes where you expect. So, what is changing things, why, is it a bug that can be fixed, what the hell?
