Gathering information on subprocesses through ruote-rest

[Patrick]

While I was experimenting with subprocesses, I ran into a problem with
getting information on the state of the subprocess through ruote-rest.
If I submit a (relatively) simple process:

class Test0 < OpenWFE::ProcessDefinition
sequence do
subprocess :ref => "http://locahost/test_process2.rb"
participant :ref => "alpha"
end
end

where http://localhost/test_process2.rb is:

class Test1 < OpenWFE::ProcessDefinition
sequence do
participant :ref => "bravo"
end
end

and alpha and bravo are active participants, the process submits fine
(for this example, we'll call the resulting process 20090710-
kikenapaju).

Checking GET /processes/20090710-kikenapaju, I get information on
Test0, but there doesn't seem to be a way to see what's going on
inside Test1. If I check GET /workitems, I can see there is a
workitem named 20090710-kikenapaju.0/0_0_0 (which I assume is the one
inside Test1 for this process), but when I try GET /workitems/20090710-
kikenapaju.0/0_0_0, I receive the following message:

File not found: /workitems/20090710-kikenapaju.0/0_0_0

Because the participant in Test1 is an active participant, if I can't
GET/PUT to it, the process just waits indefinitely. Is there a way to
do the GET/PUT I need, or can subprocesses not have active
participants in them?

Thanks!

Hello Patrick,

you have found a serious bug in ruote-rest, it's unable to present
workitems (and expressions) belonging to subprocesses.

http://github.com/jmettraux/ruote-rest/issues#issue/5

I will try to fix that ASAP and we will make sure this issue doesn't
appear in the upcoming ruote-kit.

Many thanks,

Hello Patrick,

I have fixed (well my tests seem to indicate I have) the issue.

Two commits were required :

ruote : http://github.com/jmettraux/ruote/commit/2ca67d78cc440f5e61861718595046f9f99e52e0
ruote-rest : http://github.com/jmettraux/ruote-rest/commit/5467a3e97e70bee7a89c02ef2939518d3ab0e6d4

Please tell me if there are still remaining issues and I'll fix them.

Thanks again,

[Patrick Clark]

Hi John,
Thanks for the quick fix! I'll be sure to let you know if I run
into any other issues as I test these updates.

Thanks,
Patrick
