Dynamic Check Box Error

Question

Hi All,
        I have created Dynamic UI Checkbox which is creating dynamic checkboxes based on the database Table fields.
Here is my code in Start View

Hook method called to modify a view just before rendering.
This method conceptually belongs to the view itself, not to the
controller (cf. MVC pattern).
It is made static to discourage a way of programming that
routinely stores references to UI elements in instance fields
for access by the view controller's event handlers, and so on.
The Web Dynpro programming model recommends that UI elements can
only be accessed by code executed within the call to this hook method.
@param wdThis Generated private interface of the view's controller, as
       provided by Web Dynpro. Provides access to the view controller's
       outgoing controller usages, etc.
@param wdContext Generated interface of the view's context, as provided
       by Web Dynpro. Provides access to the view's data.
@param view The view's generic API, as provided by Web Dynpro.
       Provides access to UI elements.
@param firstTime Indicates whether the hook is called for the first time
       during the lifetime of the view.

But iam not able to add attribute in the statement
int ttlcolumns=rsmd.getColumnCount();
         wdComponentAPI.getMessageManager().reportSuccess("Populating Data1");
          IWDNodeInfo node=wdContext.getNodeInfo().addChild("DynamicNode",null,true,true,false,false,false,true,null,null,null);
          //node.addAttribute("BrandID","BrandID:com.titan.retailauditreport");
          node.addAttribute("BrandID",);
its throwing an error
Error:com.sap.tc.webdynpro.services.exceptions.WDTypeNotFoundException: type Boolean not found
Is that my database connectivity code ?
Can anybody plz help me out?

Hi,
    It didnt work.So i changed my coding,Iam able to get checkbox.
Here is my code
