How can I get the id of the workflow instance in workflow form?


I have the FreeMarker template, which is the custom field for display some data about the business process.

Let's say, userdetails.ftl:

<@link href="${url.context}/res/components/workflow/workflow-form.css" group="workflow"/>
<#include "/org/alfresco/components/form/controls/common/utils.inc.ftl" />

<div class="form-field">
   <div id="...">
      <table id="..." class="yui-dt">
         <tr>
            <th class="yui-dt-liner">Field_1</th>
            <th class="yui-dt-liner">Field_2</th>
            <th class="yui-dt-liner">Field_3</th>
            <th class="yui-dt-liner">Field_4</th>
            ...
            <th class="yui-dt-liner">Field_N</th>
         </tr>
         ...
      </table>
   </div>
</div>

<script>

// Here I want to call REST back-end and parse the JSON response

</script>

Relevant part of the share-config-custom.xml:

<config evaluator="task-type" condition="mswf:reviewTask">
  <forms>
     <form>
        <field-visibility>
           <show id="mswf:userDetails" />
        </field-visibility>
        <appearance>
           <set id="userDetails" appearance="title" label="User Details" />
            <field id="mswf:userDetails" set="userDetails" label="User Details">
                <control template="/org/alfresco/components/form/controls/workflow/userdetails.ftl" />
            </field>
           <field id="transitions" set="response" />
        </appearance>
     </form>
  </forms>
</config>

This template contains a table in which I would like to display the list of users who will participate in the business process (who was assigned).

Inside tags <script></script> I want to invoke an embedded Alfresco WebScript (or my own - it's not important in this case) which returns me all the necessary information about the business process:

http://localhost:8080/alfresco/api/-default-/public/workflow/versions/1/processes/26205/variables

,where 26205 == id of the process instance.

I get the following:

            }
         },
         {
            "entry":{
               "name":"mswf_requiredApprovePercent",
               "type":"d:int",
               "value":100
            }
         },
         {
            "entry":{
               "name":"nrOfCompletedInstances",
               "type":"d:int",
               "value":0
            }
         }
      ]
   }
}

In addition to everything else I'm interested in this part:

"entry":{
   "name":"bpm_assignees",
   "type":"cm:person",
   "value":[
      "first",
      "second"
   ]
}

Here is the list of the users who will participate in the business process (in this specific instance).

To get all this information, I need to know the ID of the process instance (26205 in this case).

Can I determine this identifier in my userdetails.ftl template?


Solution

  • The workflow ID is indeed one of the variables available in your workflow, I suggest you add it to your form using the hidden form-control hidden.ftl and then, from you JS snippet, use dom to access that hidden input by ID/name and use it in your logic as you see fit !
