[Gui4j-user] radio buttons grouped

[Linu H. <lin...@ya...>]

Hello
I am creating an interface with the use of gui4j and it requires 2 radio buttons. They have to be in the same group, in order to be able to choose one at a time. I cannot find a way to do this,please help me.

<radioButton guiId="radio1" text="'Active'" group = "mygroup" />
<radioButton guiId="radio2" text="'Deleted'" group = "mygroup" />

i understood from the documentation that there is an attribute "group" that holds the radio buttons,but if i try to associate a value to it,i am forced to define it ,and i don't know a way to define a group element.
How can i make the radio buttons be active one at a time?
I would greatly appreciate the code for this.
Thanks, have a nice day
