Hi all,

How can I update a task property using JavaScript? The code below does not work:

<javascript>
var task = workflow.getTask("jbpm");
task.properties["wf:destinationUser"] = "new.user";
task.save();
</javascript>

Anyone?

Sure it must be simple, but i can find it anywhere.

Thanks!

João

Hello,

you can't update the properties of a task like you would on a node. What you should be able to do is the following:

var task = workflow.getTask("jbpm");
var properties = task.properties;
properties["wf:destinationUser"] = "new.user";
task.properties = properties;

There is no need to call save() as the assignment will already trigger the update in the database. Please note that this code, while apparently trivial and using a seemingly unnecessary re-assignment, is required due to the way the JavaScript environment and the involved Java objects interact.
