Problem summary

• Problem Summary: The WCM Personalization component is not  using
  the internal AbsPath cache for looking up WCM Content paths
  while rendering the results of a PZN rule, where the rule
  returns WCM content items.
  
  Detailed Problem Description:
  
  The WCM Personalization component is not  using the internal
  AbsPath cache for looking up WCM Content paths while rendering
  the results of a PZN rule, where the rule returns WCM content
  items.
  
  When resolving and Path information for the AptrixTree the
  Personalization component was looking up the ItemPaths directly
  from the ContentService, rather than using SiteUtils to retrieve
  this information, which will cache previously looked up items
  paths in the AbsPath cache.
  
  In addition we were validating the PZN rule node, by looking up
  by AbsPath everytime the rule was to be executed.
  
  Problem Analysis:
  
  When resolving and Path information for the AptrixTree the
  Personalization component was looking up the ItemPaths directly
  from the ContentService, rather than using SiteUtils to retrieve
  this information, which will cache previously looked up items
  paths in the AbsPath cache.
  
  In addition we were validating the PZN rule node, by looking up
  by AbsPath everytime the rule was to be executed.

Problem conclusion

• Problem Solution:
  
  Modified the generateTree method to use SiteUtils to fetch an
  items path so that the AbsPathCache can be used.
  
  Also modified validateSpotNameUUIDInfo, to lookup the node by
  UUID instead of AbsPath.
