#4606 [HHQ-4526] Stacktrace generating breadcrumbs for deleted res

[Hyperic Team]

http://jira.hyperic.com/browse/HHQ-4526
Still working on a reproduction, but ResourceBreadcrumbTag.isParentOfAutoGroup() can throw an NPE leading to a stacktrace when viewing resources.

The specific error is:

javax.servlet.jsp.JspException: java.lang.NullPointerException at org.hyperic.hq.ui.taglib.ResourceBreadcrumbTag.doStartTag(ResourceBreadcrumbTag.java:104)


...


Caused by:


java.lang.NullPointerException at org.hyperic.hq.ui.taglib.ResourceBreadcrumbTag.isParentOfAutoGroup(ResourceBreadcrumbTag.java:364)

That part of the code is:

            ResourceManagerLocal resourceManager = ResourceManagerEJBImpl.getOne();


            Resource parentResource = resourceManager.findResource(parent.getAppdefEntityId());


            Resource parentOfAutoGroupResource = resourceManager.findResource(new AppdefEntityID(group.getResourceId()));


    


            result = parentResource.equals(parentOfAutoGroupResource);

Parent resource is not null, but the call to resourceManager.findResource(parent.getAppdefEntityId()) returns null leading to an NPE when checking equality.
