Wires are mispositioned when using wirable fields within "group" fields

Here's a solution for the mentioned bug (maybe not the most elegant one, but at least it works.)

The problem was, that the wirable sub fields didn't have a back reference to their containers any more. Therefore, they didn't "know" at what point to stop adding up the top / left offsets and just calculated all the way done to the body element.

It did work for fields on the first level, but not for sub fields.

Solution: Just set the options.container property for sub fields of group of list fields as well.

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

In the file js/util/inputex/FormContainer-beta.js replace the method renderForm with
the following two methods:

/**

* Render the form
* @method renderForm
*/

renderForm: function() {

  this.setBackReferenceOnFieldOptionsRecursively(this.options.fields);

  var groupParams = {parentEl: this.bodyEl, fields: this.options.fields, legend: this.options.legend, collapsible: this.options.collapsible};
  this.form = new YAHOO.inputEx.Group(groupParams);

},

setBackReferenceOnFieldOptionsRecursively: function(fieldArray) {

  for(var i = 0 ; i < fieldArray.length ; i++) {
      var inputParams = fieldArray[i].inputParams;
      inputParams.container = this;

      // Checking for group sub elements
      if(inputParams.fields && typeof inputParams.fields == 'object') {
          this.setBackReferenceOnFieldOptionsRecursively(inputParams.fields);
      }

      // Checking for list sub elements
      if(inputParams.elementType) {
          inputParams.elementType.inputParams.container = this;

          // Checking for group elements within list elements
          if(inputParams.elementType.inputParams.fields && typeof inputParams.elementType.inputParams.fields == 'object') {
              this.setBackReferenceOnFieldOptionsRecursively(inputParams.elementType.inputParams.fields);
          }
      }
  }

},

Once again, now nicer to read (hopefully!)

In the file js/util/inputex/FormContainer-beta.js replace the method renderForm with
the following two methods:

   /**
    * Render the form
    * @method renderForm
    */
   renderForm: function() {
      this.setBackReferenceOnFieldOptionsRecursively(this.options.fields);
      
      var groupParams = {parentEl: this.bodyEl, fields: this.options.fields, legend: this.options.legend, collapsible: this.options.collapsible};
      this.form = new YAHOO.inputEx.Group(groupParams);
   },
   
   setBackReferenceOnFieldOptionsRecursively: function(fieldArray) {
      for(var i = 0 ; i < fieldArray.length ; i++) {
          var inputParams = fieldArray[i].inputParams;
          inputParams.container = this;

          // Checking for group sub elements
          if(inputParams.fields && typeof inputParams.fields == 'object') {
              this.setBackReferenceOnFieldOptionsRecursively(inputParams.fields);
          }

          // Checking for list sub elements
          if(inputParams.elementType) {
              inputParams.elementType.inputParams.container = this;

              // Checking for group elements within list elements
              if(inputParams.elementType.inputParams.fields && typeof inputParams.elementType.inputParams.fields == 'object') {
                  this.setBackReferenceOnFieldOptionsRecursively(inputParams.elementType.inputParams.fields);
              }
          }
      }
   },

Cool, thanks for committing!
