Share Worflow - Reusing bpm:assignee

ncunha — Thu, 09 Dec 2010 16:25:25 GMT

Hello.I'm new to the Alfresco platform and I'm having a problem when I run my advanced workflow on Share.My process is very simple: Start (Task 0) -> Task 1 -> Task 2 -> Task 3 -> End.I want all the Tasks to be possibly ran by different users and the user of the current task chooses who'

Could you post a few more details? For example your task model, process definition and form configuration.

It would also be really useful if you could post the HTTP request getting sent when you click the transition button.

Thanks for the details, I have managed to reproduce your issue and found a bug which I have raised here: http://issues.alfresco.com/jira/browse/ALF-6133

I will fix this next week.

Thank you very much for your quick support.
I'll be looking forward for the fix.

Best regards,
Nélson Cunha.

As you may or may not have seen ALF-6133 was resolved yesterday and I've made sure that you use case works as expected.

The fix is in the forthcoming 3.4 enterprise release branch at the moment, I will however, merge this to HEAD soon so that it is in the 3.4.c community release too.

Sorry to dig up this thread but I have the same objective that Nélson Cunha, that is to have a few tasks that the next assignee is defined by the actual assignee.

I am using the 4.0.c comunity version , and if the assigne doesn't change nothing wrong happens, but if I try to change, on share I get the "java.lang.ClassCastException: org.alfresco.service.cmr.repository.NodeRef cannot be cast to java.util.List" when submiting the task done button or save changes.

I can change the assign the bpm if I use

 execution.setVariable('bpm_assignee', "User name or Variable with a user");‍

But can't change if I use the user picker that I found on the other workflows.I use the user picket the following way:

 <forms>
                        <form>
                                <field-visibility>
                                           …
                                        <show id="bpm:assignee" />

                                </field-visibility>
                                <appearance>
                                           …
                                        <set id="assignee" appearance="title" label-id="workflow.set.assignee" />
                                           …
                                        <field id="bpm:assignee" label-id="workflow.field.assign_to"
                                                set="assignee" />
                                           …
                                </appearance>
                        </form>
                </forms>‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

I have the exact same issue in Alfresco 4.0.d community edition. Can anyone please help? Is there any workaround?

Thanks,

Re: Share Worflow - Reusing bpm:assignee

I'm also seeing the same error in Alfresco 4.0.d CE.
In my case, I have a revise/resubmit task that allows changing the bpm:assignee association.
If I don't change it, the revise task completes successfully.
If I do change it, the revise task fails with the NodeRef cannot be cast to java.util.List error

The workflow was developed on 4.2.e CE and works fine there, successfully updating the bpm:assignee association when it is changed in the form.

Anyone know of a fix or workaround for 4.0.d?
