Get handle to the documents inside a panel which is within a repeat control from outside the repeat control - xpages

Question

I am working on this functionality where-in I need to provide the user with a list of documents and provide an option for the user to change/add values to a field(s) inside these documents. I was going through this example Xpages - Display filtered Document Collection in a repeat control and did a similar implementation and got it to work. So what I have now is a panel inside a repeat which has its data source set with the form and document id set to return the value in the repeat control variable (which is the document UNID from the document collection), thus I am able to bind fields directly to these documents using the data source defined in the panel. The challenge is that I want to get the handle to these documents to set a particular value in them and also save the values in the fields that I bind to the back-end document. Is there any way I can access the documents from outside the repeat control (let say on the click of a button)? Following is my code for the repeat:
<xp:repeat id="rptApprDocuments" rows="30" var="apprDoc"
indexVar="docIndex" first="0">
<xp:this.value><![CDATA[#{javascript:// Look up the employee details view to get the employee appraisal details from the current database
var curDB:NotesDatabase = session.getCurrentDatabase();
var vwlkApprView:NotesView = curDB.getView("vwlkApprAllFGCompAppr");
var collDocAppr:NotesDocumentCollection = vwlkApprView.getAllDocumentsByKey(sessionScope.key);
var apprDocCount = collDocAppr.getCount();
if(apprDocCount != 0){
var docAppr:NotesDocument;
var docUNIDArray = new Array();
for(i=0;i<apprDocCount;i++){
docAppr = collDocAppr.getNthDocument(i+1);
//print(docAppr.getUniversalID());
docUNIDArray.push(docAppr.getUniversalID());
}
viewScope.put("docUNIDArray",docUNIDArray);
return docUNIDArray;
/*return collDocAppr;
/return sortColByItemName(collDocAppr, "AppraiseeCWLCluster");*/
}
return null;

You can access the data sources of a panel, see http://xpageswiki.com/web/youatnotes/wiki-xpages.nsf/dx/Work_with_datasources#Reset+%2F+clear+a+datasource for example code.
But that solves only half of the problem, you need a handle to each panel inside the repeater.
You can find an XPages API browser on openNTF (I don't know the exact name at the moment). Taking this, you can examine the repeat's control at runtime and check for methods and properties. I bet there is something to get components that are inside the repeater.
