Hi,
RTx::WorkflowBuilder is a tool that helps you configure multi-stage
approval workflow in rt.
It is now available at RTx-WorkflowBuilder-1.02 - Helpers for building workflow for queues in RT - metacpan.org.
examples can be found in the doc at rt-workflow - helper for configuring approval workflow in RT - metacpan.org

Hi Chia-liang,
This looks good, although it doesn’t appear to work smoothly yet.
In your pod you have:
% bin/rt−workflow PO PO‐Approval −−create
Which should probably read:
% bin/rt−workflow --create PO PO‐Approval
When I had set up the workflow within my RT_SiteConfig.pm, and run the
bin/rt-workflow script to create the scrips and templates, I naturally
created a ticket. Nothing happened, but I noticed in the logs there was the
following entry:
Found 0 scrips for TransactionBatch stage with applicable type(s)
So, I changed went into:
Configuration -> Queues -> crs -> Scrips
and changed “Stage” from “Transaction Create” to “Transaction Batch”.

It transpires the approval ticket is actually created, although I am unable to

every right imaginable. Further, when I reject the (hidden) approval, this
appears to be succesful. However, when I resolve the (still hidden)
approval, I see the following error:

Hi Chia-liang et al,
It transpires the approval ticket is actually created, although I am unable to
see it unless I look up the id directly, even though my user currently has
every right imaginable.
Approval tickets are of type “approval” - They’re supposed to be hidden
from the normal UI and visible only under the “Approvals” tab.
Further, when I reject the (hidden) approval, this
appears to be succesful. However, when I resolve the (still hidden)
approval, I see the following error:
I’m going to defer to CL on this one.
I made sure each subject line was on single line and replaced a couple of
stray dashes, (I think the \xE2 was
a “−>” thing instead of a “−>” thing in the auto-generated template from
bin/rt-workflow - which was installed via
the CPAN), like this:Did you copy and paste from perldoc?
I hear you, and guilty as charged. Although the templates were auto-generated
out of the ‘perl -MCPAN’ installed RTx::WorkflowBuilder itself, I recall
cut’n’pasting just one small part of the subject line into the
RT_SiteConfig.pm Naturally, bin/rt-workflow took my consequently naff
subject line and used it in the templates…
If so, you’re running into nroff/man being “too smart”.
LC_ALL=C perldoc RTx::WorkflowBuilder will get you things you can copy
and paste safely.
Good to know, thanks. All the same, the golden rule is:
"_never_ cut'n'paste!"

I hear you, I suspect it’s a rights issue which I have yet to resolve. The
erroneous characters were I suspect responsible for a lot of hidden mischief,
and have reinstalled from scratch and with a much cleaner environment things
are looking a lot better, thanks. If I actually get this up and running I
might even be tempted to take a stab at a clear walk through descr. on the
wiki. At the moment there are three or four separate pages for the approval
system…
Further, when I reject the (hidden) approval, this

Currently this, (“HasUnresolvedDependencies” → undefined value), is the only
outstanding issue.

This case was a multi-stage approval, the single-stage passed just fine. In
fact one-, two-, and four-stage approvals were all fine too, it was just the
three-stage approval which failed consistently in this manner.
If you look at the (hidden) approval ticket by putting the ticket id
into Display.html, do you see DependedOnBy containing the actual
ticket or other approvals?
Well, there are three approval tickets, so it’s not so simple to explain…
What I did notice was that under the failing three-approval the “Refers to:”
line appeared to have a missing checkbox, or an empty line, depending on what
way you look at it. I’ve attached a screenshot to show what I mean, maybe
this helps?

ok, so at which stage of resolving causes the issue?
can you traverse the “depends on” link to see if it reaches to the one
