Hi Jeff,

Thanks for the workflow tutorials …

I am trying to implement a workflow on folder in Alfresco share (Alfresco 3.4).

I have added workflow action to folder, and i am able to start workflow on Folder.

But requirement is any user whom the task is assigned can add other document also to that folder.. and that document will be part of workflow for coming stages.

Can you suggest how to achieve that …?

Thanks.

There are two ways you can do this that I can think of. First, if you are routing the folder in the workflow, the folder itself is in the workflow package. So when your workflow performs operations on the items in the package, the code can just drill into the folder, and any document in the folder will be accessible to the workflow. This is probably the easiest approach.

An alternative approach would be to set a rule on folders that would be triggered when new items are added to the folder. The rule would check to see if the folder is part of a workflow. If it is part of a workflow, the rule could get a handle to the workflow package and then add the new document to the workflow package.

I'd definitely go with the first option if it works for you.

The error you are getting, 404, means that the browser asked the server for a page and the server couldn't find it. This could indicate that your server never fully started. In order for me to provide any assistance, you'll need to provide any errors or stack traces you are seeing in your Alfresco log file. In your case, that log file lives in c:\Alfresco\tomcat\logs\catalina.out.

Hello Jeff, I followed his tutorial and everything worked! I wonder if I have to enter information in a SQL Server database from within the file ExternalReviewNotification.java after sending the email?

Thank you.

[SOLVED]

to solve the problem only enter a database connection in the class ExternalReviewNotification.java

what is the error you are facing?
And which link you are referring?
There is nothing much specific related to the version as far as workflow is concerned.

you can do it using a rule. You can create a rule which execute a javascript script when a file is uploaded in a folder. In the javascript file you can start a workflow.

you can pass variable to your workflow which will store a nodeRef to the document(s) which are needed in the workflow.

All of my tutorials live here: http://ecmarchitect.com/alfresco-developer-series

The rules and actions tutorial is linked to from that page, or you can go directly to it here: http://ecmarchitect.com/images/articles/alfresco-actions/actions-article-2ed.pdf

The second edition was tested on 4.0.c. I have not personally tested it against any 4.2 community versions, so if you try it out, I'll be curious to hear how it goes.

Hi,
on page 32 the tutorial states that variables inside a script task (and the whole Javascript code snippet) should be written between !CDATA:


<scriptTask id="scripttask1" name="Submit" scriptFormat="javascript">
<script><![CDATA[var scwf_approveCount = 0; var scwf_tpApproved =
false;]]></script>
</scriptTask>
‍‍‍‍‍‍

In the workflow definition you attached the CDATA section is missing.
Hope this helps.

Rgeards,
Andrea

Hi abarisone
First,thank you for your answer,I have modify like what you said,but it does't work,do you know what another reasons cases this trouble?thank you for your answer again!

Re: Advanced Workflow Tutorials

Comparing the snippet above with the latest version of the workflow, I notice that the activiti:autoStoreVariables attribute is missing. I wonder if that could be it. See below.


    <scriptTask id="scripttask1" name="Submit" scriptFormat="javascript" activiti:autoStoreVariables="true">
      <script>var scwf_approveCount = 0; var scwf_tpApproved = false;</script>
    </scriptTask>
