For a regular geo I get the local bounding box by getting a bounding box info from its shape node.
pyobj = selected()[0] #py.nt.Transform
shpbb = pyobj .boundingBox()#datatypes.
pyobj = selected()[0] #py.nt.Transform
shpbb = pyobj .boundingBox()#datatypes.
BoundingBox
Now, let's say I have 3 different objects under a group node. How can I get this group node's object space bounding box?
Any help would be very much appreciated. Thank you so much!

Thank you Ian.
I've tried the exactWorldBoundingBox command and yes it works with an object under root. But when I parent it to something else and transform it would no longer match. For example, I have a cube parented to a group node which is translated and rotated and uniformly scaled. and I run this command and locators will not match the bounding box of the cube.
And this is why I got the BB from the shape node and multiply by worldMatrix. This method always worked. And as I mentioned in my first post. I am trying to do this on a group node which has no shape node. So I am lost here :)
Would you please tell me what I am doing wrong here? Thanks again.
pyObj = selected()[0]
wbb= exactWorldBoundingBox(pyObj)
wbb_max = datatypes.Point(wbb[0:3])
wbb_min = datatypes.Point(wbb[3:6])
olocx = spaceLocator (p=wbb_max)
olocn = spaceLocator (p=wbb_min)

Just in case anybody wondering how to do this. ThE_JacO from cgtalk answered my question. If you are interested take a look.

If you get a script going, I'd be interesting in having a look!
