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!

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"…

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 Smiley Happy .

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>
