Error with JavaScript on XDP form rendered as HTML

Question

I have saved a form as an XDP and am rendering it as HTML with LiveCycle Forms Server ES. When I click on certain form buttons that cause JavaScript code to fire, I get the following error:
this._peer is undefined
I've seen this error posted in a few Adobe forum posts without answers. Any ideas?

It is a regular button that fires code that does a popup dialog box. It works fine when the form is rendered as a PDF; I get the "this._peer is undefined" error when I render it as HTML and try to run the code. Here's the code:
var insert_clauses =
result:"cancel",
DoDialog: function(){return app.execDialog(this);},
strpop1:"",
SetListSel:function(list,path){if(path.length == 0) return;
eval("list[\""+ ((typeof path.join != "function")?path:path.join("\"][\"")) + "\"] = 1")},
GetListSel:function(oLstRslts,path){
   for(var item in oLstRslts){
      if( ((typeof oLstRslts[item]=="number")&&(oLstRslts[item]>0))
         || this.GetListSel(oLstRslts[item],path) )
       {path.push(item);return true;}
   return false;
initialize: function(dialog)
//this.xfa.form.Ultra_Form.Page1.clauses.rawValue;
//var listpop1 = {"Clause1": -1,"Clause2": -2}
var listpop1 = {};   
//listpop1["Select a clause to insert"] = 1;
//xfa.resolveNode("xfa.datasets.data.Ultra_Form.Page1.clauses").value
var arrClauses = xfa.resolveNode("xfa.datasets.data.Ultra_Form.Page1.clauses").value.split("||"); //
var num=0;
while (num < (arrClauses.length))
  var test = arrClauses[num];
  listpop1[test] = -num;
  num+=1;
//dialog.load({"pop1": listpop1});
this.SetListSel(listpop1, this.strpop1);
var dlgInit =
"pop1": listpop1,
dialog.load(dlgInit);
commit: function(dialog)
var oRslt = dialog.store();
var path = new Array();
this.strpop1 = (this.GetListSel(oRslt["pop1"],path))?path.reverse():"";
