rules declaration for form valdation

[Jan Juno]

How can I avoid if hell?

and declare rules for my form validation. I have project which has an
extensive form on which when you check on chceck box than this and this will
be disabled this is enabled, and so on. In the end you end up with huge if
else if else.

How can I avoid it in wicket?

if you can just avoid push operation (if. setThatcomponentEnabled ...else
setThatComponentDisable).

Use a Pull approach, override the isEnabled of your component and make it
query the boolean value of your model.

i.e::

form.add(new TextField(myId){
public boolean isEnabled(){
 return ((MyObject)getModelObject()).getMyBooleanProperty();
}
});
