retrieve workflow instance from task id

[vale_arna84]

Hello,

Is there a way to retrieve a workflow instance from a task id using javascript apis? I would like to add some notes to a document shared by a series of review and approve tasks. For now I'm getting the tasks related to a logged user with a workflow.getAssignedTasks(), but I don't know how to retrieve the workflow instance. I'm planning to add a "note" variable to the workflow. Is there a better way to create and access a text variable related to a workflow content?

Thanks

Valerio

Valerio,

I'm not sure what you mean by "shared by a series of review and approve tasks".  Do you mean you have many workflows running against the same document?  Also, you talk about adding notes to a document and you also talk about adding a "note" to the workflow, so I'm not sure which you want to do.  I'll assume the former.

You can get the package (and from there the doc) from the task id this way:

var taskId = args["taskId"];
var task = workflow.getTaskById(taskId);
// Assuming there is only one document, 
// if you have more you'll need a loop…
var theDocument = task.getPackageResources()[0];‍‍‍‍‍
