Advanced Workflow initiated via a Rule

nowhere — Thu, 19 Feb 2009 23:59:34 GMT

Hi all,I have a very stupid question…can I initiate an advanced workflow by a rule in web gui?I have read there is a "start-workflow" action, but I found pour documentation about it. Can someone tell me where read more?Thanks!

I'm interested in that too. Do you find a way to do that ?

You could execute a workflow with the "Execute script" action.
Scripts are in the "Company Home > Data Dictionary > Scripts" repository.

The script execute the workflow automatically .

Script example :


var workflow = actions.create("start-workflow");
workflow.parameters.workflowName = "jbpm$alwf:my_workflow";
workflow.execute(document);

Thanks, but than, how can I use "document" in the workflow ?
for example I would like to check the status of the file document.properties["af:status"], but he says "document is not define".

Same problem…
I've error when I use document.name…

<node name="hello">
   <transition name="" to="end1">
      <action class="org.alfresco.repo.workflow.jbpm.AlfrescoJavaScript">
         <script>
            <expression>
               logger.log(document.name);
            </expression>
         </script>
      </action>
   </transition>
</node>‍‍‍‍‍‍‍‍‍‍‍

Have same solution?

It seems that we have to use something like "bpm_package.children[0].name" (children[0] for the first item, if you have more attached files in your workflow, you have to use a "for" loop). But I have the same problem "bpm_package is not defined"…

Re: Advanced Workflow initiated via a Rule

cytrix — Fri, 29 May 2009 08:09:13 GMT

Perhaps by creating a docName variable in your script ?

exec_workflow_action.js :


var workflow = actions.create("start-workflow");
workflow.parameters["bpm:docName"] = document.name;
workflow.parameters.workflowName = "jbpm$alwf:my_workflow";
workflow.execute(document);
‍‍‍‍‍‍

In the processdefinition file :


<node name="hello">
   <transition name="" to="end1">
      <action class="org.alfresco.repo.workflow.jbpm.AlfrescoJavaScript">
         <script>
            <expression>
                  logger.log(bpm.docName);
            </expression>
         </script>
      </action>
   </transition>
</node>

Yes, i think it works .

Try this to use bpm_package (it's works for me) :


<action class="org.alfresco.repo.workflow.jbpm.AlfrescoJavaScript">
            <runas>admin</runas>
              <script>
               <variable name="bpm_package" access="read" />
               <variable name="companyhome" access="read" />
               <expression>
                  for (var i=0; i &lt; bpm_package.children.length; i++) {
                     var dest = companyhome.childByNamePath("documents validés");
                     bpm_package.children[i].move(dest);
                  }
               </expression>
              </script>
           </action>

Try add <expression> after the variable access definition :


   <node name="Message">
      <transition to="end">
         <action class="org.alfresco.repo.workflow.jbpm.AlfrescoJavaScript">
            <script>
            <runas>admin</runas>
            <variable name="bpm_package" access="read" />
            <expression>
                                   if(bpm_package.children.length != 0){
               if(bpm_package.children[0].properties["af:status"] == "Pending"){
                  logger.log("####### Status : " + bpm_package.children[0].properties["af:status"] + " need validation !");
               }else{
                  logger.log("======= Status : " + bpm_package.children[0].properties["af:status"] + " didn't need validation.");
               }
            }else{
               logger.log("No file attached !");
            }
                                </expression>
            </script>
         </action>

Sorry…I'm on late…but I found script solution as Cytrix suuggested

var workflow = actions.create("start-workflow");
workflow.parameters.workflowName = "jbpm$alwf:my_workflow";
workflow.execute(document);

The technique to initiate an Advanced Workflow via a Rule is documented on the Wiki: http://wiki.alfresco.com/wiki/WorkflowAdministration#Step_7:_Integration_with_Rules_.28Optional.29

Hope this helps,

Re: Advanced Workflow initiated via a Rule

Hi,
I need little change in Advanced Work flow

First let me write my requirement
1. user will send document(the change is document is a folder not a file) to multiple users for review.
2.the reviewers will get the notification with document link.
3. the reviewers approve/reject the document with their comments
4. the approved folder will move to approved space and rejected folder will move to draft space for next iteration.

I am able to start jbpm workflow as soon one folder is created, after user have as approved , I am able to move that folder to a desired destination.

Right now the reviewers are static users name specified in the javascript

I want know how can I assign reviewers dynamically

here is my javascript for assigning and starting of the jbpm workflow via rule using execute script option

var workflow = actions.create("start-workflow");
workflow.parameters.workflowName = "jbpm$wfarallelreview";
workflow.parameters.requiredApprovePercent = 20;
workflow.parameters["bpm:workflowDescription"] = "Please review and approve: " + document.name;
workflow.parameters["bpm:assignees"] = people.getPerson("nithin");
var futureDate = new Date();
futureDate.setDate(futureDate.getDate() + 7);
workflow.parameters["bpm:workflowDueDate"] = futureDate;
workflow.execute(document);

I think I need to add wizard kind of action for this rule. when I try to get actions definitions for "Start Advanced Workflow" in the web-client-config-actions.xml, I didn't find any definition for this action.

I am using existing process definition (parallelreview_processdefinition.xml, parallelreview_group_processdefinition.xml)

So Please help me
Thanks

I got one more link with similar question and didn't find any example to create wizard for space.

http://forums.alfresco.com/en/viewtopic.php?f=34&t=10441&st=0&sk=t&sd=a

I am not able to understand the end to end steps to create wizard to a space.

if anyone have example of how to create a wizard to a space to get the users dynamically and execute the scripts, please let me know.

Thanks
