Unable to deploy BPM projects with human tasks from BPC

Question

I’m trying to edit and deploy a BPM process from Business Process Composer (web based tool). To do it, I followed the steps below:
1.     I created I project in JDeveloper
2.     I created the Human task from using the “Auto-generate task form” option
3.     I converted it to a template
4.     I published it to BPM MDS
5.     On Business Process Composer I created I new project based on my published template
6.     And I finally I deployed it with no errors.
When I ran the BPM it creates I human task but I’m not able to access its form on Business Process Workspace.
On Business Process Workspace I can see the task created by my BPM process, but when I click on it to access its form I get a 404 message (message below).
Error 404--Not Found
From RFC 2068 Hypertext Transfer Protocol -- HTTP/1.1:
10.4.5 404 Not Found
The server has not found anything matching the Request-URI. No indication is given of whether the condition is temporary or permanent.
If the server does not wish to make this information available to the client, the status code 403 (Forbidden) can be used instead. The 410 (Gone) status code SHOULD be used if the server knows, through some internally configurable mechanism, that an old resource is permanently unavailable and has no forwarding address.
I think this error occur because my Task form project was not deployed. To fix it I undeployed all the applications and then I deployed the BPM application with all its tasks forms from JDeveloper. It worked fine (I can actually access the task form on Business Process Workspace), but now I’m not able to edit the BPM process on Business Process Composer anymore.
Then I finally repeated the steps 3 to 6 on top of this post in order to make the BMP process editable on Business Process Workspace but this time I receive the error at the end of this post taken from server log.
No matters if I publish the project on MDS BMP repository as a template project or as non template project. I always have the same problem.
So, how can I use a BPM project that contains Human Tasks forms on Business Process Composer?
I’m using:

Answer 1

I came across the same issue, and now resolved it like this.
Firstly, you shouldn't deploy QuoteProcessLab with other UILabs like ApproveDealUILab and so on. So, if you already did it, then go to Weblogic EM and undeploy it.
Secondly, you should deploy each of UILab separately as standalone application. So, deploy EnterQuiteUILab, BUsinessPracticesUILab, and so on each. These will run independently behind and when your project created based on template in the Composer runs, it will link each of these on human task.
Thirdly, publish you QuoteProcessLab. And follow the book about how to create a project based on template in the Composer.
Just one thing you should be careful with is, when you do auto-generation for human task, it sometimes doesn't work fully, unfinished halfway through. So, make sure that the icon 'go to existing business form taskflow' in .task file takes you to the human taskflow.
If it fails, do another auto-generation. Sometimes DataBindings.cpx can get corrupted by JDev, but let's not go too far for now.
Mostly, it will work.
