Hi,
You can loop through the node of combo box1:
List attrList = new ArrayList();
IPrivate<VIEW NAME>.I<NODE NAME>Element ele = null;
for(int i = 0;i<wdContext.node<NAME>.size();i++){
    if(wdContext.node<NAME>().get<NAME>elementAt(i).get<ATTR_NAME1>().startWith("A")){
        // ATTR_NAME1 is the attribute mapped to checkbox1.
        // create element of another attribute which should be mapped to checkbox2.
        ele = wdContext.create<NODE NAME>Element();
ele.set<ATTR NAME2>(wdContext.node<NAME>().get<NAME>elementAt(i).get<ATTR_NAME1>());
        // ATTR_NAME1 is the attribute mapped to checkbox1.
attrList.add(ele);
wdContext.node<NAME>.bind(attrList);
Hope this will solve your problem.
thanks & regards,
