Looking up node references in Share forms

I am trying to display a category field as text in a Share Freemarker form context (actually an adapted version of category.ftl control).

I can easily display the node reference of a category field using ${field.value?html} which displays as:

workspace://SpacesStore/1d5b8f4a-a2a7-11dc-8d74-6f45f39984e5‍

but don't know how to translate that into human readable category text.

The general Alfresco Freemarker documentation includes this example:

${companyhome.nodeByReference["workspace://SpacesStore/e661dccb-ecc0-11da-9974-63f65406985a"].id}‍

However, companyhome doesn't appear to be present in the forms context. If I try to use it I get the Freemarker error "Expression companyhome is undefined".

Does anyone know how to look up the category properties from its nodeRef in Share forms and form controls, or can point me to docs on the root objects and methods available to Freemarker in these contexts?

Thanks

Hi,
one way to solve your requirement is to add a XHR-Request to your Repository when the browser renders the form control, e.g.

<div class="form-field">
   <div class="viewmode-field">
      <span class="viewmode-label">${field.label?html}:</span>
      <span class="viewmode-value" id="${fieldHtmlId}-value">${field.control.params.displayValue}</span>
      <input type="hidden" name="${field.name}" id="${fieldHtmlId}-hidden" />
   </div>
</div>
<script type="text/javascript">//<![CDATA[
(function()
{
   YAHOO.util.Event.onContentReady("${fieldHtmlId}-hidden", function ()
         {
            var element = YAHOO.util.Dom.get("${fieldHtmlId}-hidden");
              element.value = "";
              
              // define success handler
               var successHandler = function PreselectCategory_successHandler(response)
               {
                  //your code…
                  element.value = response.json.data.name;
               };
               
               // define failure handler
               var failureHandler = function PreselectCategory_failureHandler(response)
               {
                 //your code…
                  
               };
               
                var url = Alfresco.constants.PROXY_URI + "your repo webscript url");
               // call the webscript
             var config =
             {
                method: "GET",
                url: url,
                successCallback: 
                { 
                   fn: successHandler, 
                   scope: this
                },
                failureCallback:
                {
                   fn: failureHandler,
                   scope: this
                }
             };
             Alfresco.util.Ajax.request(config);
         }, this);
    
})();
//]]></script>
