Greg,
I've ran into the same problem when I first started working with the framework.
What helped me alot was looking at the ProjMgr Project that Kevin includes with his framework. In the future you might want to look at some of those examples. They provide good ideas as well...
Here what I did to requery on the subsequent pages of a pageframe:
cListBizObj1.cParentBizObj =
cListBizObj1.lAutoPrimaryBizObj = .T.
cListBizObj1.lRequeryChildOnRequeryParent = .T.
cListBizObj1.lUIEnablerNewRecord = .F.
cListBizObj1.nRequeryType = 1
An example for the parent biz obj would like "InvoiceHeaderBizobj" if in fact your page 2 happens to be "InvoiceLineItemBizObj".
Another thing to keep in mind is that is you are subclassing from cListObjEdit Class your BizObj will be contained in it. All you're doing is adding a Data Environment to it.
Good luck! Let me know if this worked for you...
