getting faces context instance in the java backed web script

I understand that that the Java backed web script is outside the JSF lifecycle when it is called by the any 3rd party tool.
So i just wanted to know what could be the other workaround for the same

You should use the nodeService to retrieve the properties from the node using the references you get from the searchservice. The nodeService has no references to the FacesContext (at least, that i know of) …

Thanks rogier.oudshoorn,

You should use the nodeService to retrieve the properties from the node using the references you get from the searchservice. The nodeService has no references to the FacesContext (at least, that i know of) …

My thought is that once i get the node object i will put that in the model and then i will iterate that node object in the ftl to get its property

alfNode = new Node(currentNodeRef);
resultList.add(alfNode);

and then
Map<String, Object> model = null;
model.put("node", resultList);

In this case i did`nt find any api to get the node object from nodeService
so while iterating the node object in the ftl i am geting the error "java.lang.IllegalArgumentException: FacesContext must not be null".

my ftl is like this

<#if node?exists>
   {
      "total":"${total}",
      "type":"${type}",
      "result":[
      <#list node as n>
      {"Id":"${n.properties["km:Id"]}",
         "Title":"${n.properties["km:Title"]}",
         "Type":"${n.properties["km:Type"]}"}
      <#if n_has_next>,</#if>
      </#list>
      ]
   }
<#else>
   {
      "total":"0",
      "type":"${type}",
      "result":""
   }
</#if>

Can you share with us all your code with all the imports?
I think that you are using a wrong import class in your code.

"Title":"${n.properties["km:Title"]}",

<#if n_has_next>,</#if>
</#list>
]
}
<#else>
{
"total":"0",
"result":""
}
</#if>

also in the ftl when i say n.assocs["ia:userSpaceAssoc"].it is giving me the error like "n.assocs" is undefined.

I am not able to figure out how to get the node object without the faces context instance.

Urgent help is required as i am running out of time.

Thanks & Regards

Finally, i resolved this issue.

What i did was

NodeRef currentNodeRef = row.getNodeRef();
resultList.add(currentNodeRef);
String resultJSON = searchUtils.buildResult(resultList);
resultJsonObj.put("resObj", resultJSON);
resourceJSONArr.put(resultJsonObj);
model.put("resultNodeRef", resourceJSONArr.toString());
‍‍‍‍‍‍‍

and finally into the js which empty by now i did

<import resource="classpath:alfresco/templates/webscripts/com/xyz/json.js">
var nodeRefList = resultNodeRef;
function main()
{
   //var nodeRefList = resultNodeRef;
   //model.resultNodeRef = resultNodeRef;
   var resultList = null;
   var finalResultList = new Array();
   if(resultNodeRef!="[]")
   {
      var resultJSONArr = json.parse(resultNodeRef);   
      for(var i=0;i<resultJSONArr.length;i++)
      {
         var resultsStr = resultJSONArr[i].resObj;
         model.resJson = resultsStr;
         resultList = resultsStr.split(",");
      }
      if(resultList!=null)
      {
         for(var i=0;i<resultList.length;i++)
         {
            var resultNode = search.findNode(resultList[i]);
            finalResultList.push(resultNode);
         }
      }
      model.results = finalResultList;
   }
   else
   {
      //model.results = resultList;
   }
}

main(); ‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍
