[Seaside] Seaside, Omnibase, OmnibaseSupport - markDirty failing

That is true, but BLGPost inherits from ODBSPersistentObject which
takes care of this for me, or at least tries to.  I changed it to
raise an error if it can't, just for debugging.  I think that there is
a problem with this, but I can't figure out what it is.  If I create
the objects in a workspace, I can modify them without any problems.

Creating in the workspace.
BLGDatabase current execute:
	[|post posts|
	post := BLGPost new.
	post title: '1'; body: 'body'.	
	posts := (OmniBase root at: #BLGPost).
	posts add: post; markDirty.
	post title: '2';].

When updating inside Seaside, I need to pass the post
asPersistentReference.  So I tried changing the post accessor to this

	^ post isNil
			[BLGDatabase current execute:
				[post := BLGPost new asPersistentReference]]
		ifFalse: [post]

Didn't help.  I'm pretty sure that the problem is the way I am
creating new objects in Seaside.  I just have no idea how to fix it.
