[opencms-dev] CmsJspNavElement and getCmsObject

[Sebastian Himberger]

Hi,

you can not cast a CmsJspNavElement into an CmsJspActionElement since 
the latter is no subclass of the first(CmsObject no = 
((CmsJspActionElement)ne).getCmsObject();). So i would create the 
CmsJspActionElement and the CmsObject outside your loop and then just 
call a method on them:

CmsJspActionElement cmsa = new CmsJspActionElement(pageContext, request, 
response)
CmsObject cmso = cmsa.getCmsObject();

while (...) {
  ...
  if (...) {
     List l = cmso.readResources(ne.getResourceName());
  }
}

I hope i got your questions right. I've not looked up the excact API so 
please bear with me if there are some minor errors in the code.

best regards
Sebastian
