How to assign Kaleo Workflow to User instead of Roles

[Vishal Panchal, modifié il y a 11 années.]

Hi All,

I created my custom workflow definition.xml file now I am able to upload it and assign to my custom portlet.
I am successfully able to assign approval tasks to specific ROLES.

Now , my problem is I wanted to assign approval task directly to particular users instead of roles.

For that I saw this link--http://www.liferay.com/documentation/liferay-portal/6.0/administration/-/ai/workflow-with-kal-2
And found <user/> tag is there in definition.xml file as below,
<assignments>
<user />
</assignments>

But don't have any idea about how to specify a value in <user /> tag.

Any help will be appreciated.


Thanks & Regards,
Vishal R. Panchal

According to the dtd,
<assignments>
<user>
<user-id>user id</user-id>
</user>
</assignments>

OR

<assignments>
<user>
<screen-name>screen name</screen-name>
</user>
</assignments>

OR

<assignments>
<user>
<email-address>email address</email-address>
</user>
</assignments>

Hi rino alias,

I think according to DTD it is not possible but yes one way is still there.

you may try following steps,

1) first you can create a usergroup
2) assign number of users to a user group
3) create one role and associate it with the usergroup
so what happened a role which u assigned to a user group is ultimately assigned to each of the members assigned to the same user group.
4) now you can assign the work flow to the role which you have created for usergroup by using code below.

<assignments>
<roles>
<role>
<role-type>regular</role-type>
<name>sample-usergroup-role</name>
</role>
</roles>
</assignments>

I never tried it but according to me it must work.!

Hi Vishal Panchal,

I have a issue. I wanna assign task to logging user. Therefore, I user a script by groovy
import com.liferay.portal.kernel.util.GetterUtil
import com.liferay.portal.kernel.workflow.WorkflowConstants
import com.liferay.portal.model.User
import com.liferay.portal.service.UserLocalServiceUtil

long userId = GetterUtil.getLong((String)workflowContext.get(WorkflowConstants.CONTEXT_USER_ID))
User user = UserLocalServiceUtil.getUser(userId)

But It shows this error:

import com.liferay.portal.kernel.util.GetterUtil
import com.liferay.portal.kernel.workflow.WorkflowConstants
import com.liferay.portal.model.User
import com.liferay.portal.service.UserLocalServiceUtil

Could you support me this problem.

Vinoth kumar Palanisamy:

Initialise the property 'roles'.It should work.
Add this to the groovy script
roles = new ArrayList<Role>();

Seriously? That's your response? Tell me where exactly in his workflow xml are you going to put this code?

Hi Vishal Panchal.

I have the same problem that Rino has. Well, I followed your instructions, but doesn't works.

What I have seen, is that when I create a Role (whatever type it is... regular, site or organization), and assign that role to a user group... the users of that group doesn't show in the option "Assign to..." of the task in the workflow.

But, when the role is assigned directly to a specific user (member of the site where the workflow performs), the user is shown in the list of the option "Assign to..." of the task in the workflow.

Well, I don't know if is the normal behaviour of Kaleo Workflow... or there is a solution for this.

I really would appreciate your help.

Thank you in advance.

[Balázs Csönge, modifié il y a 9 années.]

Hi

We using liferay with Activiti workflow engine instead of Kaleo, but the problem with user-group related role is same.
my problem and my solution

So it is not Kaleo specific behaviour. Maybe Kaleo engine is using same way to get user list, like Activiti:

List<user> roleUsers = UserLocalServiceUtil.getRoleUsers(roleId);</user>

But this returns only those users which are related to the role directly. After some days of suffering I found the way, how can I get the list of those users, who are related to a role only through a user group. Check my last post at that topic.

My code represents a test case, so if more user groups are related to a role, my code will not join the list of users. It only show the way, how can u get user lists.
In Kaleo you will get companyId different way than me (because of the difference between Activiti and Kaleo), but the rest will be the same, I think.

Hi All ,

Am trying to assign Approvers in workflow dynamically using script assignment .

import com.liferay.portal.kernel.util.GetterUtil;
import com.liferay.portal.kernel.workflow.WorkflowConstants
import com.liferay.portal.kernel.service.ServiceContext

import com.liferay.portal.kernel.model.User;
import com.liferay.portal.kernel.service.UserLocalServiceUtil;

long companyId = GetterUtil.getLong((String) workflowContext.get(WorkflowConstants.CONTEXT_COMPANY_ID));
ServiceContext serviceContext = (ServiceContext) workflowContext.get(WorkflowConstants.CONTEXT_SERVICE_CONTEXT);
long classPK = GetterUtil.getLong((String)workflowContext.get(WorkflowConstants.CONTEXT_ENTRY_CLASS_PK));



User approver=UserLocalServiceUtil.getUser(70101);
println("<<<<< user Information is >>>> "+ approver);
user.add(70101);
roles=null;


also i tried to put users in List

users=new ArrayList<User>();
users.add(approver)

but am getting below error .

Hi Anjaneya E, you must do a trick inside the source code of kaleo in order to be able to add "users" variable into scripted-assignments block. By default, kaleo only accepts "roles" and "user" (only one user, not a list of them). So it does not expect "users", but a single user, and it complains because you didn't specify "user" variable.

So just put user = approver and it should stop complaining (user = null should also work).
If you need to assign this task to more than one user (for example, all members of an organization) then you need to tweak kaleo-web source code but it is not that difficult. Let me know if you need that, and I send you mi code.

I hope it helps!

Hi Pallavi,

As far as assigning users, what you're doing should work, using the screen name.

You can also use the user-id tag and pass the user id, or the email-address.

You can then assign the next task to a role. Assign the role to your group, and you should get what you're looking for.

Here's an example using an existing role:

    <assignments>
        <roles>
            <role>
                <role-type>organization</role-type>
                <name>Organization Administrator</name>
            </role>
        </roles>
    </assignments>
