Error in automation chain created "workflow"

[Beatrizspereza1]

I followed the steps on the http://doc.nuxeo.com/display/Studio/One+step+validation+workflow+tutorial guide,

then it apears on my Nuxeo DM, all the folders in my workflow definition (beta) appears under the domain... and do nothing.

Also i dont know how to bind it to the automation chain created...

When I tried the button in a new document, there is a error message that says:

An error ocurred while executing te chain "workflows". No type adapter found for input: class.org.nuxeo.ecm.automation.core.dateWrapper and output class java.util.date> Contex.FetchDocument:run> workflow.CreateTask:Run

what can i do??? Why it happens?

Can you replace the @{CurrentDate.days(7).format("yyyy-MM-dd'T'kk:mm:ss'Z'") by @{CurrentDate.days(7).date") to tell me if it works. I will change the documentation if this is the case.
