Avoid getObject on Model if component not rendered
Hello, anyone have an idea how to avoid getting model object if component is
not rendered?
ListModelCustomUser usersListModel = new ListModelCustomUser() {
private static final long serialVersionUID = -4520573537970008038L;
@Override
public ListCustomUser getObject() {
return customUserDetailsService.loadAllUsers();
}
};
final DropDownChoiceCustomUser usersChoice = new
DropDownChoiceCustomUser(usersList, customUserModel, usersListModel, new
ChoiceRendererCustomUser(username));
usersChoice.setNullValid(false);
usersChoice.setModelObject(usersChoice.getChoices().get(0));
usersChoice.add(new
AjaxFormComponentUpdatingBehavior(onchange) {
private static final long serialVersionUID = 7L;
@Override
protected void onUpdate(AjaxRequestTarget target) {
target.addComponent(customUserForm);
}
});
add(usersChoice);
In some cases, usersChoice component is not rendered, becouse it is in
SecuredPanel, witch shown only for admin users. But when page loading, this
always calls secured service. I can make it unsecured to solve the problem,
and call this service always, but maby there is a way to stop calling the
service? :D
Any ideas?

Re: Avoid getObject on Model if component not rendered
Create and add the DropDownChoice in onInitialize(). If the component is not
rendered then that method will not be called (untested)
@Override
protected void onInitialize() {
super.onInitialize();
final DropDownChoiceCustomUser usersChoice = new
DropDownChoiceCustomUser(usersList, customUserModel, usersListModel, new
ChoiceRendererCustomUser(username));
usersChoice.setNullValid(false);
usersChoice.setModelObject(usersChoice.getChoices().get(0));
usersChoice.add(new AjaxFormComponentUpdatingBehavior(onchange) {

Or, just set the default value in onConfigure of the dropdownchoice itself,
which will not be called if the ddc is not visible.

Re: Avoid getObject on Model if component not rendered
AFAIK onConfigure() is _always_ called, also when a Component is invisible;
If I recall correctly this was done to remove the
callOnBeforeRenderIfInvisble() method and switching visibility in
onBeforeRender().

Re: Avoid getObject on Model if component not rendered
correct. onconfigure() can be used to control visibility - which
includes making an invisible component visible.

Re: Avoid getObject on Model if component not rendered
Doh! You're right. onInitialize of the parent component makes sense, or
else write a custom model that gets the selected choice from the choices[0],
which wouldn't be invoked if the ddc wasn't visible.
