Retrieve taskId from custom control share tier

[evoci]

I am trying to integrate a custom control within my custom workflow derived from bpm:workflowTask, in Alfresco 4.2.
My custom control invokes a webscript in the repo tier, and I need to pass the taskId for which the control instance is running to that webscript.
My goal is to retrieve task variables from the webscript by using

var taskId = args["taskId"];var task = workflow.getTaskById(taskId);‍‍

I don't know how to retrieve the taskId in my control.inc.ftl; any hint appreciated.

Hi,

You can get the task id using

${args.itemId}‍

in any control of the task-edit form.

I succeded in retrieving itemId, thanks.
That however appears to be the id of the workflow definition, not the id of the instance, therefore I cannot use it to retrieve the variables.
Did I miss something?

On which form are you trying to get your task id ?

The itemId is the workflow definition id on the start task form, but it should be the task id in any other task edit form.
