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:

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?
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 !
