I'm not sure but with alfresco, you cannot restrict a document to people just with meta-data, you've got to move your document to a folder with specific rigths (READ for example) when it has been accepted.

Thanks guiyan17, Is it possible to remove READ access in some spaces?

Senthil

Re: Workflow Implementation

guiyan17 — Mon, 19 Feb 2007 11:23:13 GMT

Yes you just have to delete the rigth "READ" for the group EVERYONE and nobody will see documents into the folder. Then you can invite on this folder groups or users with the rights you want…

I tried the same and it doesn't seem to be working. Do you think any other reason why it is not working in my case?

Senthil.

when you say it doesn't work, what do you mean? With no group invited on the folder, you can still see your document?

Hi,

I have a space in which all the users have Consumer role. I have a content rule applied to the space with a workflow. I follwed the process as it is in the Alfresco book.

I login in as usr and upload document in a folder called Draft and assign permissions to other users on that content. After this I try to submit this document for Review [ if it wrkd the document wud move to Pending space] , the system throws an error as below.

Failed to approve the document due to system error: Access Denied. You do not have the appropriate permissions to perform this operation.

Please assist me with this

Thanks,
Vidi

Guiyan17, yeah still I can see the document. But I could resolve it by creating another role called "No Access" with no permissions. Now it is working fine. I have a weird error in workflow implementation, please help if you know any workaround.

Hi All:

I found a weird problem in Alfresco 1.4. If you create a user with username as number, ex: username = 123, My Tasks To Do & My Completed Tasks are empty when we start Advanced Workflow.

This work fine if the user name contains only alphabets. Has anyone had this kind of problem before? Is there any restriction available on having username as numbers?

I have also tried number+alphabet combination it doesn't seem to be working, please help!

Thanks,
Senthil

Well why not it is a solution, maybe not the easiest, but if it works… :wink:

I have a weird error in workflow implementation, please help if you know any workaround.

You can try this wiki:

I worked on it, and now it works, but some point are not easy to understand so if you've got questions, ask them…

There was an issue in 1.4 community where usernames were encoded incorrectly in the task dashlets. This is fixed in 1.4 enterprise and 2.0 community.

David,

Thanks for your reply. Is there any workaround available on Alfresco 1.4 community?

Thanks,
Senthil.

Re: Workflow Implementation

davidc — Thu, 22 Feb 2007 12:39:12 GMT

- restrict your usernames
- patch your version of 1.4 (I can give details if you're willing to go this route)

Re: Workflow Implementation

senthil_chinnai — Thu, 22 Feb 2007 14:31:25 GMT

David,

We can not restrict user names. Basically user names are numbers in our organization.

Could you please provide me the patch details? I would like to do that.

Thanks,
Senthil.

Re: Workflow Implementation

davidc — Thu, 22 Feb 2007 14:39:48 GMT

You can also move to 2.0. This will be released any time now.

To fix you need to remove ISO9075.encode from:

getTasksCompleted()
getTasksTodo()

in WorkflowBean.java.

Thanks so much David, I will try the fix.

Hi,

Would there be a way to move a content from a space to another , by using the advanced worklow, based on the actions available?

eg: in the advanced workflow, a content could be assigned to a reviewer [ Review and Approve or the Adhoc ] After this the content appears in the reviewers my task list. here the review "Manages Task" and sets the status to Completed and clicks on Approve and finishes the task.

At this point , can the approved content automatically be moved to anther space? Could a mail also be triggered at the same time?

Please help.

Thanks
Hari

Re: Workflow Implementation

davidc — Fri, 23 Feb 2007 10:35:43 GMT

Yes.

Within an advanced workflow definition, you can hook Alfresco javascript (or java) to events within the workflow. Common events include "on transition", "on node enter", "on node leave" etc.

See http://wiki.alfresco.com/wiki/WorkflowAdministration#Actions_.26_Scripting

So, you can essentially perform any operation you like when a user completes a task.

Hi,

We are custmizing the workflow in alfresco[ Advanced Workflow ]

As a part of this we need to send mail alerts to the initiator when the content is approved in the "Review & Approve" cycle of the advanced workflow.

I have made some changes to the review_processdefinition.xml and the workflowModel.xml as below

review_processdefinition.xml

<transition name="reject" to="rejected" >
<action class="org.alfresco.repo.workflow.jbpm.AlfrescoJavaScript">
<script>
var mail = actions.create("mail");
mail.parameters.to = initiator.properties["cm:email"];
mail.parameters.subject = "Review Task " + bpm_workflowDescription;
mail.parameters.from = reviewer.properties["cm:email"];
mail.parameters.text = "It's done";
mail.execute(bpm_package);
}
</script>
</action>
</transition>

<transition name="approve" to="approved" >
<action class="org.alfresco.repo.workflow.jbpm.AlfrescoJavaScript">
<script>
var mail = actions.create("mail");
mail.parameters.to = initiator.properties["cm:email"];
mail.parameters.subject = "Review Task " + bpm_workflowDescription;
mail.parameters.from = bpm_assignee.properties["cm:email"];
mail.parameters.text = "It's done";
mail.execute(bpm_package);
}
</script>
</action>
</transition>

workflowModel.xml

<type name="wf:completedReviewTask">
<parent>bpm:workflowTask</parent>
</type>

<type name="wf:rejectedReviewTask">
<parent>bpm:workflowTask</parent>
</type>

even after this there are no mails getting triggered.

Please let me know how could make this possible?

Thanks ,
Hari

P. This feature is similar to the notify me option in the Adhoc workflow, but that we do not want the Notify Me check box

David,

I tried changing subject & body of Adhoc email configuration, it doesn't take any changes. Please help !

I have changed the following line just to see the change, but it doesn't seem to be working. Is there any other place I need to change?

\tomcat\webapps\alfresco\WEB-INF\classes\alfresco\workflow\adhoc_processdefinition.xml"(40,42): mail.parameters.text = "It's doneeeeeeeee"

Thanks,
Senthil.
