NullPointerException occurs and sections do not load

SA-71240

Summary



NullPointerException occurs and sections do not load in the Test environment. The sections are stored as a control in the UI when opened from Designer Studio.


Error Messages



pzSectionBody_1(); /* Problem executing pzAssemblePreprocess for RULE-HTML-SECTION HEALTHCARE-FW-NEMSWFW-WORK SEARCHFACOVERAGEFILTER java.lang.NullPointerException */


Steps to Reproduce

  1. Open Designer Studio.
  2. Create a section.
  3. Perform a section include in a dynamic layout.

Root Cause



An issue in the custom application code or rules.
When working with the portal, the user may have a single access group with a single access role. The Read Rules privilege for @baseclass was insufficient to work with pzAssemblePreProcess. Additionally, the pzAssemblePreprocess activity of section class was not triggered. Hence, some properties were missing in the section XML code.


Resolution



Perform the following local-change:
  1. Set the Read Rules privilege for @baseclass to 5.
  2. Delete the caches entries with the following queries:

    delete from pr_sys_appcache_shortcut where pzimplementationkey like 'html_section.ra_stream_mytestsection_%';
    delete from pr_sys_appcache_entry where pzimplementationkey like 'html_section.ra_stream_mytestsection_%';
    delete from pr_sys_appcache_dep where pzimplementationkey like 'html_section.ra_stream_mytestsection_%';

  3. Apply the HFix-26748 (existing) to force trigger the pzAssemblePreprocess activity of section class FUA for all sections.
  4. Resave the section (in which the issue is encountered) to recreate the missing properties.
  5. Clear the cache.
