Problems with vote example

Hi People

I am new with Roo (Nice project). I am using Roo 1.1.2 Release fbc33bb.

I have complete the first app and ten-minutes app with no problem and after that I have beginning with the manual.

When I access roo interface it said to me that I have to upgrade 18 packages. I have done.

After that, I have started to show the samples scripts and they don't works. For example, the vote sample response with the error:

Unable to scaffold controller for type com.springsource.vote.domain.Choice The referenced type com.springsource.vote.domain.Choice cannot be handled.

Maybe are these examples not updated to last roo release? Has any link between this errors and last upgrade?

Thank you very much
