LinkBuilder to Action convert error in CRS 10.1.2 MediaBanner.jsp

Question

Hi, we are now trying to build MediaBanner.jsp on CRS 10.1.2, based on the similar one in discover. We have put following on MediaBanner.jsp, and get following error:
++<c:url value="${util:getUrlForAction(contentItem.link)}" var="hrefUrl"></c:url>++
++</c:if>++

How this error van be resolved ?

Answer 1

You have two options, if your cartridge is like MediaBanner, and at least has media and link objects, you just need to use OOTB MediaBanner handler in the properties file.
Otherwise, you first have to define the class you will use for MediaBanner handler, and in that class you will need to convert linkBuilder to linkaction like this:
- your class needs to extend from NavigationCartridgeHandler
- in the process method, you will need to get linkBuilder object
- and then get linkAction object like this:
linkBuilder.createAction(this.navigationStateBuilder, this.contentSource, getActionPathProvider())
Does it make sense?
