Hi,

IWDInputField inputField = (IWDInputField) view.createElement(IWDInputField.class, "<ID for your input>")

inputField.bindValue("<Attribute to which this should be bound>");

and finally add this to a container

Ex:

IWDTransparentContainer container = (IWDTransparentContainer)view.getElement("<RootUIElementContainer>");

IWDInputField input= (IWDInputField)view.createElement(IWDInputField.class,null);

IWDAttributeInfo iWDInfo = (IWDAttributeInfo) wdContext.getNodeInfo().getAttribute("<Your Attribute Name");

input.bindValue(iWDInfo.getName());

container.addChild(input);

Hi,

Can you post the code from your WDmodify.

Either you are accesing the continer which doesnot exist. or else trying to bind to a attribute which is not present.....

Hi,

To Create an attribute dynamically

wdContext.getNodeInfo().addAttribute("<name>", "<dataType>");

Ex:

wdContext.getNodeInfo().addAttribute("name","ddic:com.sap.dictionary.string");

Hi,

You have to write the code for creation of UI elements in side the condition

If(firstTime)

{

// Your Code for UI Creation

}

Else every round trip it will try to create the UI comp.
