Newbie Question, Very Basic Model Use
After using property models, it's nice to have automatic binding to variables
in objects... However, I can't seem to get the same thing to work with local
variables... as an example...
new CheckBox("toggleSomething", new PropertyModel(someObject,
"toggleableProperty"));
works beautifully...
However,
new CheckBox("toggleSomething", new Model(toggleableObject));
//toggleableObject is a Boolean
doesn't seem to change anything on form submit, that toggleable object only
dictates the initial state of the checkbox, but doesn't change with it....
What am I missing?

Model assigns a new object as the model object, and I think
java.lang.Boolean is immutable so it can't change after it's constructed
anyway. So instead of checking the value of toggleableObject I think you
can check myCheckbox.getModelObject() == Boolean.TRUE etc..

If you would like the property model to work with local variables do
new propertymodel(this,"property")
