RadioButton in ADempiere

I use checkbox with callout for radiobutton

For example:

if(A_Tab.getValue("female") == true)
    A_Tab.setValue("male", false);
else
    A_Tab.setValue("male", true);

return "";

Then, I apply this rule into field "CallOut" of tab "Column" of screen "Tables and Columns"

CallOut:

@script:beanshell:SelectGender
