using callback comment

bodo

Hi,
I use an external task and have a callback in my script like
$task->CallBack($callback_value, $callback_msg);
Now I'd like to use in case of error the $callback_msg in the following cgitask.
Where can I get it?
Thx in advance,
Bodo

You want to use the callback message from a previous [external]task in a subsequent cgitask?

The easiest way I can think of to do this is to insert the message as a job (or task) variable before performing the callback - so that the subsequent task can then retrive it from that variable.

Look at the CreateVariable() / SetVariable() / GetVariable() methods for both WFtask and WFworkflow - for more details

Thank you for the hint,
it's working.
Greetings, Bodo

sub WF_var {
if (!$workflow->GetVariable("wf_comment")){
$workflow->CreateVariable("wf_comment", @_);
} else {
$workflow->SetVariable("wf_comment", @_);
}
$comment = $workflow->GetVariable("wf_comment");
Protocol("Workflow-Comment: $comment\n");
}
