kiran_428

Hi, I am trying create a simple work flow for moving documents from one space to another space for approval using a rule .But I am not able to show this a task in the dash board.Can any one help me?

I am having the same problem. Does anyone get the solution to this issue???

Thanks!!!

I think that is imposible to create a workflow with tasks using the action rule "add simple workflow." You shuold create a rule that "executes a script" and this scrit startys the workflow.

If you need any help just tell me.

Hello everybody!
I'm quite new on alfresco and I'm trying to takethe most of the simple workflows and spaces rules. I would like to create a simple workflow which 'll execute a script. Do you have an idea or any clues!
thx

Hi Tarl,

If you want to execute script you can use a space rule and in the action you simply choose the option "Executes a script…" to set the script you want to execute.

Indeed, if you need to have a workflow that will be associated to a user who is the responsible of execute the action that will trigger the script you need to modify the simple workflow of alfresco.

For example I created an Approve / Reject worklflow tha in the Approve task executes a script which copy a documento and change the expiry date of this document. For this you need to edit the file review_proccessdefinition.xml like follows:

review_proccessdefinition.xml

<?xml version="1.0" encoding="UTF-8"?>

<process-definition xmlns="urn:jbpm.org:jpdl-3.1" name="wf:review">

    <swimlane name="initiator" />

    <start-state name="start">
        <task name="wf:submitReviewTask" swimlane="initiator" />
        <transition name="" to="review" />
    </start-state>

    <swimlane name="reviewer">
      <assignment class="org.alfresco.repo.workflow.jbpm.AlfrescoAssignment">
         <actor>#{bpm_assignee}</actor>
      </assignment>      
    </swimlane>

    <task-node name="review">
        <task name="wf:reviewTask" swimlane="reviewer">
            <event type="task-create">
            </event>
        </task>
        <transition name="reject" to="end" >
           <action class="org.alfresco.repo.workflow.jbpm.AlfrescoJavaScript">
              <script>
               fechaInicial = new Date();
               fechaCaducidad = new Date();
               fechaCaducidad.setDate(fechaInicial.getDate() + 10);
               for (var i = 0; i &lt; bpm_package.children.length; i++){
                     bpm_package.children[i].properties["cm:expiryDate"] = fechaCaducidad;
                     bpm_package.children[i].save();
                  }
              </script>
           </action>
      </transition>
        <transition name="approve" to="end">
           <action class="org.alfresco.repo.workflow.jbpm.AlfrescoJavaScript">
              <script>
                  var dest = companyhome.childByNamePath(bpm_aproveDestination);
                  for (var i = 0; i &lt; bpm_package.children.length; i++){
                     bpm_package.children[i].copy(dest);
                  }
                  fechaInicial = new Date();
                  fechaCaducidad = new Date();
                  fechaCaducidad.setDate(fechaInicial.getDate() + 10);
                  for (var i = 0; i &lt; bpm_package.children.length; i++){
                        bpm_package.children[i].properties["cm:expiryDate"] = fechaCaducidad;
                        bpm_package.children[i].save();
                  }
              </script>
           </action>
      </transition>
    </task-node>

    <end-state name="end" />

</process-definition>‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Then to launch this workflow I use a rule that execute a script and send a task Approve / Reject to the user I want. As yo see:

startWorkflow_CLIENTES.js

var workflow = actions.create("start-workflow");
workflow.parameters.workflowName = "jbpm$wf:review";
workflow.parameters["bpm:workflowDescription"] = "Review source by Init Services.";
workflow.parameters["bpm:assignee"] = "responsibleUser";
workflow.parameters["bpm:aproveDestination"] = "THEINIT/CLIENTES";
workflow.execute(document);‍‍‍‍‍‍

I hope this will help.

tarl

thx witho for such a fast answer!
I understand what you say but this wil modify the Review &approve advanced workflow. It ll be better for me if I could add some scrpts to the simple wf. The one where the user can click on a button to launch the workflow. I hope you understand what I mean… More accurately, I want that a user who's done with a content in the drafts folder can click a button "request Approval" in the drop-down menu. This will launch the scripts and the workflow.
best regards

Hi again Tarl,

For your porpose you can use webscripts, but I am not an expert in this stuff. I leave you some tutorials that I hope will help you, here you are:

http://wiki.alfresco.com/wiki/Web_Scripts
http://wiki.alfresco.com/wiki/Web_Scripts_Examples

Another option could be trying to edit the "start-workflow" action and add a "onclick" parameter before the action call. Something like this (I'm not sure if this will work…):

web-client-config-workflow-actions.xml

         <action id="start_workflow">
            <label-id>start_workflow</label-id>
            <image>/images/icons/new_workflow.gif</image>
            <evaluator>org.alfresco.web.action.evaluator.StartWorkflowEvaluator</evaluator>
            <onclick>javascript:yourFunction();return false;</onclick>
            <action>wizard:startWorkflow</action>
            <action-listener>#{WizardManager.setupParameters}</action-listener>
            <params>
               <param name="item-to-workflow">#{actionContext.id}</param>
            </params>
         </action>
‍‍‍‍‍‍‍‍‍‍‍‍‍

tarl

thx witho! I think I get it! any Idea for a script or web script to reach another web site (url)?
Anyway thx you !

witho

I am glad it worked!

I don't understand what exactly do you mean with "a script or web script to reach another web site (url)". Could be more specific?

Bye.

tarl

I need that when the script of my "workflow" will be executed that it send information to Redmine (another web application). I think the better solution ll be to call a Remine URL with parameters inside such as http://www.myRedmine.com/myAction/attribut1=value&attribut2=valueee …
do you understand better?

witho

I think I know what you mean.

If the call to the URL is a call to an action and the result is a transaction or similar you may use an AJAX call using dojo. Somethihg like this:

      var bindArgs = {            
            url: "www.myRedmine.com/myAction/attribut1=va … t2=valueee…",
            method: "post",            
            mimetype: "text/html",             
            load: function(type,data,evt) {
               //Callback script executed after the AJAX call
            }
      };      
      dojo.io.bind(bindArgs);
‍‍‍‍‍‍‍‍‍‍‍

I hope this will help you.

tarl

It's exactly what I need but when I use it in a script call by the rule "execute a script", I got this error:

A system error happened during the operation: 09300013 Failed to execute script 'workspace://SpacesStore/5f401a17-af9d-448a-a13a-ef31ce3b426c': 09300012 ReferenceError: "dojo" is not defined. (workspace://SpacesStore/5f401a17-af9d-448a-a13a-ef31ce3b426c#9)

Do you have an Idea or do I need to configure something ?

tarl

I add that:

Utils.writeDojoScripts(FacesContext context, ResponseWriter out);

And I got this error:

A system error happened during the operation: 09300020 Failed to execute script 'workspace://SpacesStore/5f401a17-af9d-448a-a13a-ef31ce3b426c': missing ) after argument list (workspace://SpacesStore/5f401a17-af9d-448a-a13a-ef31ce3b426c#9)

Hi Tarl,

Your problem is that you have to load dojo in the JSP you are making the AJAX call. First of all you must check if you have the dojo scripts in Alfresco. You should have them in …/alfresco/scripts/ajax/dojo.

Then you must load dojo.js in your JSP adding this piece of code:

<script type="text/javascript" src="/alfresco/scripts/ajax/dojo/dojo.js"
            djConfig="parseOnLoad: true"></script>
<script type="text/javascript">
dojo.require("dojo.io.*");
</script> 
‍‍‍‍‍‍‍

tarl

hi witho! thx again
I 'm just editing a scipt in the alfresco Compagny Home/Data Dictionary/Scripts so I don't know where to put your javascript for "initializing" dojo…
cheers

witho

You must place it in the <head> element of the page (I think it would be JSP) from which you are going to make the AJAX call.

tarl

thx witho!
I did a JSP file which can execute an ajax request…that's works!
but now I need to call this file from the "execute a script" rule. is it possible?
here is an other manner to see my problem:
http://forums.alfresco.com/en/viewtopic.php?f=12&t=22732
thx

witho

I think is much easier. You don't need to create a JSP page, you just have to load the dojo in the page where the users will push the action link "start-workflow", just if you call your script from the onclick parameter of your start-workflow action.

If you are makin the AJAX request from a script executed with a rule I think you will need to find from which JSP is being your rule / script executed and add the dojo load code in the <head> element.

I'm sorry if this is not a solution to your problem, I hope this will help.

tarl

Thx again witho!
I think you have really well understood my problem:

If you are makin the AJAX request from a script executed with a rule I think you will need to find from which JSP is being your rule / script executed and add the dojo load code in the <head> element.

But I don't know or I can not find where are those JSP files. For instance I created a script call Transform&delete.js in alfresco but I don't find any file called like that. do you have an idea?
best!

witho

As far as I know you must have loaded dojo if you want to make a dojo.io.bind call. So I will try this in your javascript:

    //load Dojo (after the page's onload event has already occurred)
    djConfig = {afterOnLoad : true, require:['dojo.date','dojo.cookie']};
    var e = document.createElement("script");
    e.type = "text/javascript";
    e.src= "/alfresco/scripts/ajax/dojo/dojo.js";
    document.getElementsByTagName("head")[0].appendChild(e);
‍‍‍‍‍‍‍‍

I hope this will fit to your problem.

tarl

That was a good idea but it don't work I get this error:

A system error happened during the operation: 10030003 Failed to execute script 'workspace://SpacesStore/f3f510e3-37b5-44fa-b1a9-ab5f1bd3a44d': 10030002 TypeError: Cannot find function createElement in object Node Type: {http://www.alfresco.org/model/content/1.0}content, Node Aspects: [{http://www.alfresco.org/model/content/1.0}auditable, {http://www.alfresco.org/model/system/1.0}referenceable, {http://www.alfresco.org/model/content/1.0}titled, {http://www.alfresco.org/model/content/1.0}author]. (workspace://SpacesStore/f3f510e3-37b5-44fa-b1a9-ab5f1bd3a44d#7)

I think it is because the script is executed by the server and not by the browser… it is not regular javascript API. What do you think?

witho

You are right, the problem is tha the script is being executed by the server and the element "document" is an Alfresco document and not the page that is being executed by the browser.

You could try to look how to load dojo from a javascript. If I figure out a better solution I'll make you know.

i am have seen one of your process definations on another post
actually i wanted to ask that var dest = companyhome.childByNamePath(bpm_aproveDestination);
what should i pass actually in javascript workflow.parameters["bpm:aproveDestination"] = "Aproved";
where Approved is foldre in company home am i passing right path.because when i approve doc it dosent get moved to this folder

thanks
