Rails spinoffs - Oct 2006 - [PATCH]Allow the autocompleter to save value to a hidden field

In order to have the autocompleter save a value back to a hidden field
I propose the following patch/change:

In controls.js, change the following lines:

<code>
    if (this.options.select) {
      var nodes = document.getElementsByClassName(this.options.select,
selectedElement) || [];
      if(nodes.length>0) value = Element.collectTextNodes(nodes[0],
this.options.select);
</code>

to:

<code>
    if (this.options.select) {
if (this.options.hiddenField)$(this.options.hiddenField).value
Element.collectTextNodesIgnoreClass(selectedElement,
this.options.select);
var nodes = document.getElementsByClassName(this.options.select,
selectedElement) || [];
      if(nodes.length>0) value = Element.collectTextNodes(nodes[0],
this.options.select);
</code>

this will allow in conjunction with the "select"-option the
autocompleter to save the unselected text to a hidden field
