how add radiobutton in form Activiti Explorer

[davidparraz41]

I am trying to add a radio button to the Activiti Explorer form 
but I have not succeeded. 
I searched on com.vaadin.ui but I do not find a radiobutton either. 

Thank you.

You will need to follow the following example to create a custom form renderer:

Creating a new form property in Activiti | Small steps with big feet 

As for VAADIN, I believe you are looking for an OptionGroup.
