Ok, in the test I ran, this worked. But there is a catch.
My checkboxes are named things like AEMN, AEMP, CALF, CILCO and the such. What i would do is rename these in the Hierarchy to CB_AEMN, CB_CALF. is there a wildcard that can be put on the cb to pick up the changes?
xfa.resolveNode("page1.subform1.cb["
+ i + "]").rawValue =1;
