Hi RT Users,
since some days i play around with the actual RT 3.4.3, but from time to
time i get the following error if i got to “Tickets” The Query Builder.
Its running under Fedora Core 3 Perl 5.8.5 and installed modules…
Any Ideas or sugestions??? It is strange, this error occurs not on every
call, only from time to time.

Its running under Fedora Core 3 Perl 5.8.5 and installed modules…
Any Ideas or sugestions??? It is strange, this error occurs not on every

I was having the same problem with 3.4.3. I upgraded to 3.4.4
yesterday and haven’t had the problem (yet).

Alex,
In sub ParseQquery or Build.html, why is $$tree declared instead
of $tree?
$$tree = RT::Interface::Web::QueryBuilder::Tree->new;
When dereferencing a reference to an object are these equivalent?
$tree->GetDisplayedNodes
and
${$tree}->GetDisplayedNodes
Or am I on the wrong track here?

Nevermind. Dumb question.
Are you sure that neither of you has any local modifications?
The error indicates that $tree contains an object of class
Tree::Simple, which in fact does not have a GetDisplayedNodes
method. $tree, however, should be of class
RT::Interface::Web::QueryBuilder::Tree, a subclass of Tree::Simple.
Can you grep your installed copy of RT for Tree::Simple? When I do
that, all I get is documentation and a single ‘use base’. What do
you get?

Well, I am running Asset Tracker. Its search builder is based
on the RT code, before the major refactoring. Perhaps there is
a global variable that AT is stepping on?

Having taken a glance at the AT source, I think I understand the
problem.
This bug does not exist in vanilla RT – I don’t believe you can make
this happen without adding your own code. However, RT’s html/Search/
Build.html is written in such a way that it makes such a bug easy to
accidentally make.
Specifically, I believe that whenever you do “sub foo {” in a Mason <%
INIT> or <%PERL> block, the sub is actually defined in the package
HTML::Mason::Commands. Specifically, this means that if two
components define subs with the same name, they will clash.
I believe what we were seeing here was a clash between ParseQuery in
RT’s html/Search/Build.html and AT’s AssetTracker/Search/Build.html
— these are two separate pages, but they both define ParseQuery,
and so in some cases RT’s page ended up calling AT’s function.
It seems that defining subs in components should be avoided. (Of
course it’s usually better to put subs in lib/ anyway.) I will check
in a fix that changes the subs in html/Search/Build.html to be
closures assigned to a lexical variables; essentially, I am changing
“sub ParseQuery {” to “my $ParseQuery = sub {”.
(It looks like Elements/RT__Ticket/ColumnMap and (in 3.5) Elements/
MyRT could use a similar fix.)
