$_ not defined???

In this code section:


use TeamSite::WFsystem;
use TeamSite::Config;

my $NUMBER_OF_DAYS_AGO = 30;
my $time = localtime();
print "Starting to Remove worflows more then $NUMBER_OF_DAYS_AGO old \nStart time: $time\n---------------\n";

my $iwhome = TeamSite::Config::iwgethome();
my $wfs = new TeamSite::WFsystem();

my $num_days_ago = time() - (60 * 60 * 24 * $NUMBER_OF_DAYS_AGO);

my @tasks = map{@{$_->GetTasks()}[0];} @{$wfs->GetWorkflows()};

I'm getting the error:

Can't use an undefined value as an ARRAY reference

for this line:

my @tasks = map{@{$_->GetTasks()}[0];} @{$wfs->GetWorkflows()};

I assumed that $_ would be set to what I'm searching for...

Try examining the contents of:

@{$wfs->GetWorkflows()}

outside the

map

call - perhaps there are no workflows and it's returning an empty or undefined array. Or try rephrasing the code to be:

...
my $jobs = $wfs->GetWorkflows();
my @tasks = map{@{$_->GetTasks()}[0];} @{$jobs}; 
...

Looking at what $wfs returned (using your $jobs ref), there are workflows there. Via the interface, we've got SEVERAL (some from 2008!) that I'm trying to remove. I'm thinking maybe one of the workflows have no tasks??

That's certainly possible - GetWorkflows() returns all workflows in the system and sometimes you may have empty or even corrupted workflows left in the system - Try changing the call to GetActiveWorkflows() and see if that helps.

Just in case - it was not in the original code...
You have to declare "use TeamSite::WFworkflow;" to use it's "GetTasks" method. Have you?
