For objects that I get from session, I was trying to avoid accessing
them in the constructor but I wanted to setup my default model so that
they are pulled on the load method from a loadabledetachable model.
Which approach do you use? Here are the three approaches,
(The code below is pseudo code, I am typing it out from memory).
** Scenario 1. Add a call to the constructor.
public class SomePage extends Page {
public SomePage() {
...
...
final bigSessObjBean = WicketSession.get().getSomeObjBean(); <---
Access object from session in local constructor method scope.
final Form x = new Form("form", new
Model<ObjBean>(bigSessObjBean)) { <--- Obj bean as default model
...
}
or even...
final Form x = new Form("form") {
...
onSubmit() {
bigSessObjBean.getData(); <---- Here, accessing bigSess
Obj Bean
}
}
}
}
** Scenario 2. Use loadable detachable Model
public class SomePage extends Page {
public SomePage() {
...
...
l = new LoadableDetachableModel() {
public Bean load() {
return WicketSession.get().getSessBeanObj();
}
};
final Form x = new Form("form", l) {
...
onSubmit() {
getDefaultModel().getData(); <---- Here, accessing bigSess
Obj Bean
}
}
}
}
** Scenario 3: Call the session get when you need it.
final Form x = new Form("form", l) {
...
onSubmit() {
WicketSession.get().getSessBeanObj();.getData(); <---- Here,
accessing bigSess Obj Bean
}
}
