Sending Javascript Nested Arrays object to seam remote method using seam remoting but getting NULL in remote method

[pramanish]

Hi All,

I am trying to send Javascript Arrays containing Arrays to seam remote method but in seam remote method i am getting it NULL.

Following is my code snippets:

XHTML Code:
<s:remote include="decisionTableManager"/>
function testMe(){
     var columnAndRowArray=null;
     var columnsArray;
     theTable=document.getElementById("testform:datatable");
     var columns=theTable.tHead.rows[1];
     columnsArray=new Array(columns.cells.length);
     for(var i=0;i<columns.cells.length;i++){
          columnsArray[i]=columns.cells[i].textContent;
     }     
     var allRows=theTable.tBodies[0].rows;
     var rowsArray=new Array(allRows.length);
     var rowLength=allRows.length;
     for(var i=0;i<rowLength;i++)
     {
          var rows=new Array(allRows[i].cells.length);
          var cellsLength=allRows[i].cells.length-1;
          for(var j=1;j<cellsLength;j++)
          {
               var hiddenFieldId="hidden"+i+j;
               rows[j]=document.getElementById(hiddenFieldId).value;
          }
          rowsArray[i]=rows;
     }
     columnAndRowArray=new Array();
     columnAndRowArray[0]=columnsArray;
     columnAndRowArray[1]=rowsArray;
     alert(columnAndRowArray);
     var listMap=new Seam.Remoting.Map();
     listMap.put("columnList",columnsArray);
     listMap.put("rowList",rowsArray);
     Seam.Component.getInstance("testTableManager").testMe(listMap,callBack);
//Here in place of listMap i have also tried by passing columnAndRowArray array and in testMe parameter type i put Object[] but in that case also i am getting NULL.
}

Interface :


@Local
public interface TestTableManager {
     @WebRemote
     public boolean saveToXLS(Map<String,Object[]> listMap);
     public void remove();
     
}

Concrete Class:


@Stateful
@Name("decisionTableManager")
@Scope(ScopeType.SESSION)
public class TestTableManagerBean implements TestTableManager   {     

     public boolean testMe(Map<String,Object[]> listMap){
          System.out.println("***** saveToXLS is called *****");
          System.out.println(listMap.size());
          System.out.println("****** Printing details *********");
          try {
               String [] columns=(String[])listMap.get("columnList");
               Object [] rows=(Object[])listMap.get("rowList");
               
               List<String> columnList=Arrays.asList(columns);
               System.out.println("************Column List is as given below *********");
               System.out.println(columnList);
               List<List<String[]>> rowList=new ArrayList<List<String[]>>();
               System.out.println("**** Each Rule List *****");
               for(int i=0;i<rows.length;i++){
                    List<Object> eachRuleRowList=(List<Object>)Arrays.asList(rows[i]);
                    System.out.println(eachRuleRowList);
               }
          } catch (Exception e) {
               // TODO Auto-generated catch block
               e.printStackTrace();
          }
          //saveColumns(columnsAndRowsArray);
          return true;
     }
}


Can anybody tell me how i can accomplish my goal of passing Javascript Array of Arrays to testMe() remote method and get Actual values instead of NULL.

Thanks in advance.

Thanks,
Manish
