Igor, for now I'm concerned about how can I make sure that my code that
mimics form submitting lifecycles and wicket code in coming version do the
same things?
For instance the AjaxFormComponentUpdatingBehavior:
@Override
protected final void onEvent(final AjaxRequestTarget target)
{
final FormComponent<?> formComponent = getFormComponent();
if (getEvent().toLowerCase().equals("onblur") &&
disableFocusOnBlur())
{
target.focusComponent(null);
}
try
{
formComponent.inputChanged();
formComponent.validate();
if (formComponent.hasErrorMessage())
{
formComponent.invalid();
onError(target, null);
}
else
{
formComponent.valid();
if (getUpdateModel())
{
formComponent.updateModel();
}
onUpdate(target);
}
}
catch (RuntimeException e)
{
onError(target, e);
}
}
I should do something similar but for the list of components the behavior
takes.
If the coming version of Wicket does it a bit different I would have to
insert a fork in my code that does version check:
switch(wicketVersion) {
case ...:
case ...:
}
If wicket sources had the form processing code extracted into utility class
I would employ it and be sure it should work in the new wicket version.
