Context Mapping a dynamically created node?

Hi,

How can I create two dynamic Context nodes, one in ViewController and the other in Component Controller and finally create a context mapping between them.

    Hi MK,

    Giving you a sample code for the same :

    <b>creating a node & attribute in the component controller</b>

    // create a method in the component, write this code in it & call the method from the view

    IWDNodeInfo NodeInfo = wdContext.getNodeInfo().addChild("comp_dyn_Node",null,true,true,false,false,false,true,null,null,null);

    wdComponentAPI.getMessageManager().reportSuccess("Created a node ::"+NodeInfo.getName());

    IWDAttributeInfo info = NodeInfo.addAttribute("comp_dyn_Attr" , "ddic:com.sap.dictionary.string");

    wdComponentAPI.getMessageManager().reportSuccess("Created an attribute ::"+info.getName());

    <b>Creating & mapping a node & attribute in the view</b>

    IWDNodeInfo NodeInfo = wdContext.getNodeInfo().addMappedChild("view_dyn_Node",null,true,true,false,null,false,true);

    IWDNodeInfo comp_node_info = wdThis.wdGetDynamic_mappingController().wdGetContext().getNodeInfo().getChild("comp_dyn_Node");

    wdComponentAPI.getMessageManager().reportSuccess("Created a node ::"+NodeInfo.getName());

    wdComponentAPI.getMessageManager().reportSuccess("getting the component node ::"+comp_node_info.getName());

    NodeInfo.setMapping(comp_node_info,true);

    IWDAttributeInfo info = NodeInfo.addMappedAttribute("view_dyn_Attr",".Dynamic_mapping.comp_dyn_Node.comp_dyn_Attr");

    wdComponentAPI.getMessageManager().reportSuccess("Created an attribute ::"+info.getName());

    wdContext.getChildNode("view_dyn_Node",wdContext.getLeadSelection()).getCurrentElement().setAttributeValue("view_dyn_Attr","Test Value for dynamically created node mapping");

    wdComponentAPI.getMessageManager().reportSuccess("Reading from the new attribute ::"+wdContext.getChildNode("view_dyn_Node",wdContext.getLeadSelection()).getCurrentElement().getAttributeValue("view_dyn_Attr"));

    wdComponentAPI.getMessageManager().reportSuccess("Reading from the component attribute ::"+wdThis.wdGetDynamic_mappingController().wdGetContext().getChildNode("comp_dyn_Node",wdContext.getLeadSelection()).getCurrentElement().getAttributeValue("comp_dyn_Attr"));

    Hope this helps,

    Best Regards,

    Nibu.
