[mapguide-users] can't update and delete from feature source but insert works

[J Manafi]

Does anyone know...with an MgDeleteFeatures(or perhaps MgUpdateFeatures)
command, does the filter string have to be of a certain type? For instance,
we have features stored with a unique KEY value. It used to be of type
'Int32', and it seemed that DeleteFeatures was working back then. But then I
changed the KEY value to type 'String' to make it more dynamic, and that
seems to be when this breakdown started happening. 
Our filter string looks like this: $filter = "KEY = $ID";
Should the fact that $ID is a string matter at all?

Just for reference, I am using MG 1.2 with bundled php environment.
Does anyone have any more suggestions?
Thanks in advance for any help you give.
