This is an example (based on Link-o-matic of wicket-examples) of how to use customized state tracking.
Play with this and see how it reacts on using your back-button.
// Action link counts link clicks on works with onclick handler
final Link actionOnClickLink = new Link("actionOnClickLink")
{
public void onClick()
{
addStateChange(new Change()
{
private int tmpCount = Home.this.onClickLinkClickCount;
public void undo()
{
onClickLinkClickCount = tmpCount;
}
});
onClickLinkClickCount++;
}
};
