Can't edit dashboards after upgrading to 4.0.13

Hi,

A couple weeks after upgrading to 4.0.13 (from 4.0.7), I discovered that
whenever I click the “Content” link while editing a dashboard, I get the
error, “An internal RT error has occurred. Your administrator can find
more details in RT’s log files.” In the log is recorded:

Jul 18 16:21:39 myhostname RT: Can’t call method “Content” on an
undefined value at /opt/rt4/share/html/Dashboards/Queries.html line
126. Stack: [/opt/rt4/share/html/Dashboards/Queries.html:126]
[/opt/rt4/sbin/…/lib/RT/Interface/Web.pm:635]
[/opt/rt4/sbin/…/lib/RT/Interface/Web.pm:335]
[/opt/rt4/share/html/autohandler:53]
(/opt/rt4/sbin/…/lib/RT/Interface/Web/Handler.pm:208)

This happens whether creating a new Dashboard or editing an existing
one. We didn’t notice the problem until a couple weeks after the
upgrade since the most used features of Dashboards work as expected
(viewing, sending emails), so I’m not 100% sure it is related to the
upgrade, but I can’t think of anything else that might have caused this
to break.

I did some searching but didn’t see any other similar reports. Does
anyone have any suggestions on how to debug this further? Thanks in
advance for any suggestions.

Go have a look at /opt/rt4/share/html/Dashboards/Queries.html and
ensure that it looks like this change (which was in 4.0.12) is in your
install.

          for my $object (@objs) {
              my @items;
              my $object_id = ref($object) . '-' . $object->Id;
          
              # saved searches and charts
              for ($m->comp("/Search/Elements/SearchesForObject", Object => $object)) {
                  my ($desc, $loc_desc, $search) = @$_;
          
                  my $SearchType = 'Ticket';
                  if ((ref($search->Content)||'') eq 'HASH') {
                      $SearchType = $search->Content->{'SearchType'}
                          if $search->Content->{'SearchType'};
                  }
                  else {
                      $RT::Logger->debug("Search ".$search->id." ($desc) appears to have no Content");
                  }
          
                  my $item;
                  my $oid = $object_id.'-SavedSearch-'.$search->Id;
                  $item = { type => 'saved', name => $oid, search_type => $SearchType, label => $loc_desc };

We’ve run into a few folks who customized RT running into problems
because of local overrides to either Queries.html or SearchesForObject
that don’t take into account this API change.
