Multiple repeating SubForms binding to the same data node

Question

Having multiple repeating SubForms binding to the same data node : In our documents, many times we need to display information from same table in multiple locations. For example, if document displays information of Insureds on one page and information of drivers on another page, we need to create a LiveCycle document with two SubForms. Each SubForm needs to have a repeating binding to CommonInsured element in XSD.  LiveCycle Designer is not able to handle such case. We cannot have two subforms bound to the same node, ONLY in a case where repeating option is selected for data binding.
The only way I have found out is the following Javascript
//Get the data node from XML. You will find the code for this function in //JavaHelperFunctions library.
// InsuredDataRepeatingSubForm is a second subform.
//You need to manually add instances to this subform at the
//runtime and Insured data to each instance.
var insuArray = JavaHelperFunctions.getInsureds();
    var i=0;
    for( i=0; i<insuArray.length; i++)
       if (i>0)
var thesubform = this.InsuredDataRepeatingSubForm.instanceManager.addInstance(i);
              thesubform.InsuredName.rawValue = insuArray[i].fullName.value;
       else
               this.InsuredDataRepeatingSubForm.InsuredName.rawValue = insuArray[i].fullName.value;
Is there any way I can achieve directly using bindings since we are trying to minimize javascript that changes the layout of the form?
Thanks in advance!

Unfortunately not. I've spent countless hours/days trying to do the same thing. You have to use code. The form consumes all the data it can into the repeating elements until there is none left and it is not reused.
Here's a function I wrote just for that purpose. Feel free to use it:
function loadData(source,target){
target.setInstances(source.count);//set the target's subform instances to match the source's
for (var a=0;a<source.count;a++){//loop through each subform instance
  var sourceSubform=source.resolveNode(source.name.substr(1)).all.item(a);
  var targetSubform=target.resolveNode(target.name.substr(1)).all.item(a);
  for (var b=0;b<sourceSubform.nodes.length;b++){//loop through the children of each
   if (sourceSubform.nodes.item(b).className=="field" && targetSubform.resolveNode(sourceSubform.nodes.item(b).name)!=null)//check for matching fields
    if (typeof(targetSubform.resolveNode(sourceSubform.nodes.item(b).name).value.exData)=="undefined" ||
     typeof(targetSubform.resolveNode(sourceSubform.nodes.item(b).name).value.exData.body)=="undefined")
     targetSubform.resolveNode(sourceSubform.nodes.item(b).name).rawValue=sourceSubform.nodes.item(b).rawValue;
    else
     targetSubform.resolveNode(sourceSubform.nodes.item(b).name).value.exData.loadXML(sourceSubform.nodes.item(b).value.exData.saveXML(),1,1);
   if (sourceSubform.nodes.item(b).className=="instanceManager" && targetSubform.resolveNode(sourceSubform.nodes.item(b).name)!=null)//check for matching subforms
    loadData(sourceSubform.nodes.item(b),targetSubform.resolveNode(sourceSubform.nodes.item(b).name));
Just make sure the source and target subform hierarchies are identifal, same name and all. It will recurse down the tree and transfer source fields (rich text and plain) to their sister targets.
