1 .I am getting a promotional entity in my spring controller and then replacing the default entity that came with my CP.

@RequestMapping(method = RequestMethod.GET, value = "GetPromoItem/{entityId}")
public String getPromoItem(HttpServletRequest request,@PathVariable String entityId, @RequestParam String regionName) throws Exception {
//Get the entity from request
EntityModel entity = getEntityFromRequest(request, entityId);
final MvcData mvcData = entity.getMvcData();
//Get the Promotional item if returned for the current page/region combination
//Some code to get the promotional component id,template id based on region
PromoItemModel item=(PromoItemModel) contentProvider.getEntityModel(compId.getItemId()+"-"+templateId.getItemId(), localization);     
  if(item !=null) 
    entity=item;
request.setAttribute(ENTITY_MODEL, entity);
return resolveView(mvcData, "Entity", request);    
}

2. Registered ViewModel , rendered using promotion.jsp

<jsp:useBean id="entity" type="com.sdl.webapp.common.api.model.entity.PromoItemModel" scope="request"/>
<jsp:useBean id="markup" type="com.sdl.webapp.common.markup.Markup" scope="request"/>
<%@ taglib prefix="dxa" uri="http://www.sdl.com/tridion-dxa" %>

<div class="container-fluid ${entity.htmlClasses}" ${markup.entity(entity)}>

    <div id="location-tile" class="row">
        <div class="col-sm-6">
            <div class="tile">
                <h1 ${markup.property(entity, "headline")}> ${ entity.headline }</h1>        
            </div>        
        </div>
    </div>
</div>

On my page I can see the promotional content if available and default if not, but the XPM markup is for the default entity always.

Question-
i- how can i generate and use the XPM Markup for my promotional entity using DXA?
ii- how can i modify this markup?
(Use case is appending some extra markup - like we add Smart Target Promotion XPMMarkup)

Any examples or pointers to similar markup generation within DXA projects are welcome.

  • It's not clear to me what you are trying to achieve, nor how you are trying to achieve it, can you clarify and provide a code sample? – Rick Pannekoek Feb 3 '16 at 18:10
  • @Rick - i have modified the question and added some sample code snippets, let me know if any further info required – Ashutosh Feb 4 '16 at 5:11

I guess your controller is intended as an Entity Controller. In that case, I would recommend to inherit from class EntityController and override method enrichModel. See, for example, class ListController: https://github.com/sdl/dxa-web-application-java/blob/master/dxa-framework/dxa-common-api/src/main/java/com/sdl/webapp/common/controller/ListController.java

From which class does your PromoItemModel inherit? If it inherits from EntityModel, the XPM markup should be automagically generated.

  • Thanks for your inputs, To add Controller inherits from BaseController and Class inherits AbstractEntityModel, tried few things per reference from ListController ,no luck as of now. – Ashutosh Feb 8 '16 at 8:03
  • Also observed at the latest news module on homepage, though the data is populated dynamically but the XPM editing is not available for that data(list items/news), i feel that we are looking at an incorrect reference here. – Ashutosh Feb 8 '16 at 12:10
  • How is the PromoItemModel created? Class AbstractEntityModel generates XPM markup from the key/value pairs in the XpmMetadata property. If you create your own EntityModel from scratch, you will have to set XpmMetadata yourself too. – Rick Pannekoek Feb 8 '16 at 18:57
  • I have updated snippet in question to show the same, we are using contentProvider to create our Entity, verified it has set XpmMetadata& other properties correctly. – Ashutosh Feb 9 '16 at 5:00
  • Ok. That sound good. It's still not quite clear to me how your controller method gets invoked. Can you also show how your attempt to refactor it cf. ListController implementation looks? – Rick Pannekoek Feb 9 '16 at 18:38
