How to bind a UI element to the context

Question

Hi Experts,
           I have a problem binding UI element to the context. In my code i have to create TabStrips dynamically and under this tabstrip number of UI elements would be there. For this i have a code like this..
IWDTransparentContainer theActionContainer =(IWDTransparentContainer)view.getElement("RootUIElementContainer");
     IWDTabStrip ts = (IWDTabStrip) view.createElement(IWDTabStrip.class,"TabStrip");
          IWDTab tab1 = (IWDTab) view.createElement(IWDTab.class,"Tab1");
          IWDInputField in = (IWDInputField) view.createElement(IWDInputField.class,"in");
          IWDCaption header1 = (IWDCaption) view.createElement(IWDCaption.class,"Header1");
          header1.setText("Tab1");
          tab1.setContent(in);
          ts.addTab(tab1);
          IWDTab tab2 = (IWDTab) view.createElement(IWDTab.class,"Tab2");
          IWDInputField in2 = (IWDInputField) view.createElement(IWDInputField.class,"in2");
          IWDCaption header2 = (IWDCaption) view.createElement(IWDCaption.class,"Header2");
          header2.setText("Tab2");
          tab2.setHeader(header2);
          ts.addTab(tab2);
          theActionContainer.addChild(ts);
<b>when i run this code it is giving following exceptions..</b>
The initial exception that caused the request to fail, was:

From these exceptions what  i understood is, i need to bind these UI elements to context.
   Can any body tell me how to bind a UI element to the context if I understood the exceptions correct..
Thanks in Advance,
Murthy.

HI,
lets say Ctx is your context attribute,
IWDAttributeInfo attrInfo = wdContext.getNodeInfo.getAttribute("Ctx");
then , as per your code,
IWDInputField in = (IWDInputField) view.createElement(IWDInputField.class,"in");
<b>in.bindValue(attrInfo);</b>
if your contex attribute is child of some other node then do like this,
IWDAttributeInfo attrInfo = wdContext.getNodeInfo.getChildNode("SalesOrder",0)getAttribute("Ctx");
//this is when Ctx is child of node SalesOrder, and we are taking Ctx from its 0th element
then ,
IWDInputField in = (IWDInputField) view.createElement(IWDInputField.class,"in");
<b>in.bindValue(attrInfo);</b>
include this in your code ,
let me know if you face any problem
