Question

Hi
    At present in banner  i have  a label like  EIN :12  ( iddesc, idno) like this,
    at present EMPID  is coming from different BAPI, full description for that ein
  is Employeee Idenfication Number  that full description is coming from another
  BAPI.
Problem is   i need to display full description instead of EIN.   for that i tried
the following code,  but it is throwing null pointer exception, plz check the code.
          IModifiableSimpleValueSet dropValueSet;
          IWDAttributeInfo loc_AttributeInfo     = wdContext.nodeBanner().getNodeInfo().getAttribute("IDType1_Desc");
          dropValueSet                              = loc_AttributeInfo.getModifiableSimpleType().getSVServices().getModifiableSimpleValueSet();
          int nodeSize                               = wdContext.nodeBanner().size();
           dropValueSet.clear();
           dropValueSet.put("0","Select");
           for(int i=0;i<nodeSize;i++){
           dropValueSet.put(wdContext.nodeBanner().getElementAt(i).getAttributeAsText("IDType1_Desc"),wdContext.nodeBanner().getElementAt(i).getAttributeAsText("iD_DESCRIPTION"));
For every useful answer i will reward nice points.  Please reply asap.

Hi
To check the cardinality properties.Go to the Comp Controller or Custom Controller Context ,Right click your node and select the properties.You can now see the cardinality properties also.Change those.Your data is coming from 2 Bapis so in your used models declare the Model usages also.In the View Properties Declare the Component or Custom Controller usage whose context is binded with model.
Better you create 2 Nodes in the context each for getting the data from Different Model.So confusion in usage.
