Multiple repeating SubForms binding to the same data node

Kyle,

I wanted to use your code but as I am new to coding I have to ask a very basic question.

I have a repeating table subform which I want to duplicate on a second page.  i.e., I want row1 in the target table subform to be the same as row1 in the source table subform.

Where in the script do I identify the source and target subforms/tables.... 

Would I stop at the Row1 itentifier? i.e.,

var sourceSubform=source.resolveNode(topmostSubform.Page1.WitnessNameSubform.Table3.Row1.name.substr(1)).all.item(a);

I would appreciate any help.  Thank you in advance.  Vanessa

Thanks for the reply. Atleast gives me re-affirmation that i'm doing the right thing and there is no way to achieve this directly using bindings.

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.

"Is there any way I can achieve directly using bindings since we are trying to minimize javascript that changes the layout of the form?"

Yes. Have you created a Schema, data connection to it and bound your form elements? If you bind two elements to the same item in the data connection, when you change one, the other changes.
