My code in the init of view controller is as follows:-

<b>IWDAttributeInfo attInfo= wdContext.getNodeInfo().addMappedAttribute("dynamicAtt", "ddic:com.sap.dictionary.string");
	wdContext.currentContextElement().setAttributeValue("dynamicAtt", "Hello narpal");
    
	IWDNodeInfo localnodeInfo = wdContext.wdGetAPI().getRootNode().getChildNode("dynamicAtt",1).getNodeInfo();
		
	IWDNodeInfo poNodeInfo = wdComponentAPI.getContext().getRootNode().getChildNode("DynamicNode",IWDNode.LEAD_SELECTION).getNodeInfo(); 
	localnodeInfo.setMapping(localnodeInfo, true);</b>

Thanks in advance

hi,

okay so you want to go for mapping the contexts, use this functions

setMapping(IWDNodeInfo mappedNode, boolean selectionMapped) Sets the mapping of a mapped node that has been declared before.

addMappedAttribute(java.lang.String name, java.lang.String mappedName) Adds a new mapped attribute to the structure.

addMappedChild(java.lang.String name, java.lang.Class elementClass, boolean singleton, boolean mandatorySelection, boolean multipleSelection, java.lang.String mappedPath, boolean selectionMapped, boolean initializeLeadSelection) Dynamically declares and adds a mapped child NodeInfo with the given properties.

pleae refer these links, it wil be of help

Can we do this by addAttributes()???

Thanks

Please read the Javadoc of IWDNodeInfo.addMappedAttribute(String, String).
