I am running DNN 5.5 and just bought the DataSprings Collection.  Started by installing the Dynamic Registration.

After running the Dynamic Registration wizard and putting the basic fields of "Username", "Password", "Confirm Password" on the Registrtion page, I noticed that the drag and drop was not working to allow me to reorder the fields, or drag them to the copy and recycle areas.

Double clicking on the Error on Page icon (IE 8) I get the following
==========================================

The relevant source code for the JavaScript is
=====================================================

addSource : function(sourceId,slideBackAfterDrop,xAxis,yAxis,dragOnlyWithinElId,functionToCallOnDrag)
 {
  if(!functionToCallOnDrag)functionToCallOnDrag=false;
  if(!this.dragDropSourcesArray)this.dragDropSourcesArray = new Array();
  //Data Springs Removed For Now if(!document.getElementById(sourceId))alert('The source element with id ' + sourceId + ' does not exists');
  var obj = document.getElementById(sourceId);
  
  if(xAxis!==false)xAxis = true;
  if(yAxis!==false)yAxis = true;

356   this.dragDropSourcesArray[this.dragDropSourcesArray.length]  = [obj,slideBackAfterDrop,xAxis,yAxis,dragOnlyWithinElId,functionToCallOnDrag]; 
357   obj.setAttribute('dragableElement',this.dragDropSourcesArray.length-1);
358   obj.dragableElement = this.dragDropSourcesArray.length-1;
 }

=====================================================


I added a alert just before line 357
=====================================================
alert('before ' + this.dragDropSourcesArray.length + ' sourceId=' + sourceId + ' obj=' + obj + ' isNull=' + (obj==null));
=====================================================

and reloaded the page, I get the following output in the alert.
=====================================================
before 0 sourceId=dnn_ctr419_DynamicRegistration_imgNewField_Textbox419 obj=[object HTMLInputElement] isNull=false
before 1 sourceId=dnn_ctr419_DynamicRegistration_imgNewField_Checkbox419 obj=[object HTMLInputElement] isNull=false
before 2 sourceId=dnn_ctr419_DynamicRegistration_imgNewField_RadioButton419 obj=[object HTMLInputElement] isNull=false
before 3 sourceId=dnn_ctr419_DynamicRegistration_imgNewField_ComboBox419 obj=[object HTMLInputElement] isNull=false
...
before 19 sourceId=dnn_ctr419_DynamicRegistration_imgNewField_imgNewField_Rating419 obj=[object HTMLInputElement] isNull=false
before 20 sourceId=dnn$ctr419$DynamicRegistration$imgMove_7147b0f4-2ed4-4c78-a697-15cae32d609e obj=null isNull=true
=====================================================

The error occurs when processing this last value.
BTW, the above listing appears twice when the browser refreshes the page.  It appears the whole script is being called twice.

Any ideas on how to fix?

Hi Wayne,

Please check out the suggestion at the end of this forum thread.  It seems to have worked for him.  Thanks!

That was not a related issue.  That was a missing JS file.  The file is here, it is just throwing errors.

I tried it with Firefox and the script works there just fine. It is only in IE8 that I see the problem.

The error first occurs in IE8 when the script is called looking for sourceId=dnn$ctr419$DynamicRegistration$imgMove_6640e680-93a6-4786-bc05-82f45856a691 and it returns a null obj.

In FF, the script is called looking for sourceId=dnn_ctr419_DynamicRegistration_imgMove_6640e680-93a6-4786-bc05-82f45856a691 and it finds it.

The problem is IE8 is using three "$" in the string instead of three "_".  This could be some kind of encoding problem.

Hi Wayne - This is related to the Drag/Drop code within Dynamic Registration and specifically because of some updates to IE 8. For now you can either disable the Drag/Drop issue, use FireFox when using this feature, or ignore it as it shouldn't happen unless you are in edit mode. We are working on the next release to support Drag/Drop within IE8 the way it already works in earlier versions.
