I can tell you mine - they work for me , but whether they work for you, 
or anyone else, is a different matter.

1. NEVER lock message just to handle resizing.
       If you need to do that, you're already in a heap of trouble :-)

2. ALWAYS (and I mean always) set the lockLoc of a group.
     Don't let those uppity groups change their size - you need to be in 
charge :-)

3. Work top-down in a (fairly) strict hierarchy. Let each level of 
card/group handle the layout of its component pieces, allocate space for 
them and "set the rect .." for each.

3a. Always resize/reposition things by setting their rect (not their 
top/left/width/...).
       Every time I try to use those seemingly-convenient shorter forms, 
I get in trouble :-)

4. Design in some logging mechanism so that if something is going wrong, 
you can easily turn on logging and see what is happening, across ALL 
your resizing group / controls.

5. In the very rare occasions where there is need to cross the hierarchy 
as above, do it explicitly (e.g. I have a convention of sometimes having 
a handler "presizecontrol" which returns a *preferred* size or minimum 
size, which the upper levels of the hierarchy can use to check what 
lower layer groups would like to be, can adjust their decisions 
accordingly - and then resize ("set the rect ..") accordingly.
