Tristate boolean

2014-11-17 Thread Lucio Crusca 
Hello,

I have a sql field that is a BOOLEAN, which allows for NULL also. So it can be 
TRUE, FALSE, or NULL.

I need a component to let the user set that field to one of the three states. 
I'm thinking about using two checkboxes, one for TRUE, the other for FALSE and 
when neither is checked it means NULL. A bit of javascript would then avoid 
the both checked state.

Is there anything like that ready to use?

Thanks, I've tried it but I've not managed to make it work, the checkbox never 
changes state on click. Here is what I've done so far:

1. added maven dependency:

dependency
  groupIdde.agilecoders.wicket/groupId
  artifactIdwicket-bootstrap-extensions/artifactId
  version0.9.7/version
/dependency

2. added input tag to my form

input wicket:id=input type=checkbox /

3. added a CheckBoxX in java code:

form.add(new CheckBoxX(input, model.Booleanbind(rewind)));

where model is a CompoundPropertyModelMyBean and MyBean has a

  private Boolean rewind; // along with getter and setter

I have a suspect though: should I include Bootstrap myself in order to use 
CheckBoxX?
