AEM 6.3 PARSYS NO DECORATION

Hello,

I have a problem in the parsys: for example, in my sidebar, in preview or disabled mode, the wrapper (cq:htmlTag) of the first component is not closed, so it wrap also other components and it brokes my html.

I found several documents and guides (for example this: AEM | Remove wrapper HTML Tags in preview mode – Need is the mother of invention … , but also others), that say to set in my global.jsp this snippet of code:

<c:choose>

  <c:when test="${ requestScope['com.day.cq.wcm.api.WCMMode']=='EDIT' || requestScope['com.day.cq.wcm.api.WCMMode']=='DESIGN'}">

  <c:if test="${componentContext!=null}">

  <% componentContext.setDefaultDecorationTagName("div"); %>

  </c:if>

  </c:when>

  <c:otherwise>

  <c:if test="${componentContext!=null}">

  <% componentContext.setDefaultDecorationTagName(""); %>

  </c:if>

  </c:otherwise>

</c:choose>

The problem is that I already have a similar snipper of code, that disable decoration if it's not edit or design mode, but it not working.

I have AEM 6.3.

Thanks in advance, Daniel
