Intercept

agoldschmidt

TeamSite 6.1

I'd like to intercept the "end job" workflow action (in the professional interface) so I can call an external logging function before ending the job. Alternatively, I'd like the workflow job itself to detect the end job signal and perform the logging function itself. Any ideas on how to do either of these?

Thanks,
Allen

external task just before the endtask.

That is how IW does it with WF Monitor

agoldschmidt

I probably should have been clearer. :-) I am using an external task right before the end task to log the workflow when it ends normally. What I'm looking for is the ability to log the workflow when it is ended prematurely (through the UI). For example, say the content admin comes along and decides that a particular workflow job shouldn't have been started and decides to end it. I'd like to call the logging function right before the workflow terminates.

Good luck

Feature Request

& do not let anyone do that.

I've thought about this one before and never come up with a good answer. In thinking about it again right now, it seems like maybe you could set up an event trigger on the WorkflowInactivate event. Not sure though.

Migrateduser

Hmm, looking at the list on p.156 of the CLT manual, it doesn't look like its a supported event.

I tested it anyway, and confirmed that it doesn't work.

But, I do think that's the right paradigm for IWOV to implement it. I would be supportive of such a feature request.

nipper

Just because it is not a supported event does not mean you cannot do it. We wrote a trigger for the rename and copy events. So you can do it. Does this show up in the event log ?

The event does, but I didn't see anything firing as a result. Here's what I did:

1. Wrote super-complicated perl-script d:\foo.ipl... complete with quoting error - DOH! (let's try that again - ok, same result):



open OUT, '>D:\foo.txt';
print OUT "Test\n";
close OUT;

2. Registered the trigger:
iwat WorkflowInactivate ""d:\webapps\internal\interw~1\teamsite\iw-perl\bin\iwperl.exe d:\foo.ipl"

3. Started a workflow, did the metatagger step
4. Did an End Job

Here's what's in the event log:

5. Checked for the existence of d:\foo.txt
6. Sighed in disappointment

See anything wrong with the above?

Not reading the thread completely, I thik it's more of a notification than a trigger - if you trap that "event" your code runs after the job is gone, so your data is already lost. Not sure if that's what you're running into.

Two more words, lame architecture.

nipper

This is a little different on how we did ours.

copy iwhome/bin/iwmkdir to iwhome/bin/rob_wf_inactive

in the list ifs put something like:

elsif ($MYNAME eq "rob_wf_inactive") {
$IW_EVENT1="WorkflowInactivate";
$IW_VPATHENV="IW_FILE";
$SUBJECT1=TeamSite::Uniscape::uniscape::GetNativeMessage("$iwhome", "cltipl.cat", "15", "file or directory");
chomp($SUBJECT1);
$ARTICLE1=TeamSite::Uniscape::uniscape::GetNativeMessage("$iwhome", "cltipl.cat", "7", "a");
chomp($ARTICLE1);
$ADJECTIVE1="";
$VERB1=TeamSite::Uniscape::uniscape::GetNativeMessage("$iwhome", "cltipl.cat", "3", "created");
chomp($VERB1);
$SUBJECTPHRASE = $ADJECTIVE1 . $SUBJECT1;
}

Then this in iwlocal.cfg:

rob_wf_inactive root /iw-home/custom//bin/foo.ipl

Now this is for Unix, you use DOS so your mileage may vary.

True, the job will be gone, but we may have some information we can use. No question we cannot stop it from
happening.

Agreed, and highly lucrative, but often frustrating and tedious work. Anyway this should not be the primary goal of enterprise software vendors.

Adam Stoller

Perhaps the new reporting system that's coming in 6.5 (6.7?) will provide the ability to trap such events as job removal (as distinct from job ending) - but my guess is that you should file a feature request to have Remove Job (and iwrmjob) fire off a *different* event than an endtask does - *and* to be able to attach a PRE-operative trigger to such an event.
