How to start Wizard with an active step? / Best practise?
Hi all,
what is the best way to start a Wizard in a particular step?
I tried:
- to override onInit of WizardStep and setting this to activeStep, when
the state is the right one, but init() of WizardModel always determines
the next step after me (the current active), so this seems not to be a
good way. I could set the prevoius, but this is quite faked.
- to implement a condition; state is determined correct, but than all
buttons are deactive, hmm...
- manually setting setActiveStep() after init of WizardModel, but this
needs to unpack model object to construction time to evaluate my state
on my own (but it worked as expected).
Did I miss something? Or is the third implementation the best trade-off?
kind regards
Patrick

Hi Paul,
thanx for your answer.
I will have a look at extending it. :-)
kind regards

We need to build the WizardModel in a dynamic way. Although I think there
is a better more dynamic step too that can be used here.
So one cheap solution is to keep an enum or some sort of a definition of
your wizard steps:
public static enum WizStep {
/** Step 1 of N */ STEP_ONE(1),
/** Step N of N */ STEP_N;
...
private int stepNum;
WizStep(int stepNum) {
this.stepNum = stepNum;
}
public int getNum() {
return this.stepNum;
}
}
Then extend the wizard and build the model starting at the given step like
so:
private class MyWizard extends Wizard {
private static final long serialVersionUID = 1L;
public MyWizard(String id, WizStep startStep) {
super(id);
setDefaultModel(ediPojoModel);
WizardModel model = new WizardModel();
if(WizStep.STEP_ONE.getNum() >= startStep.getNum()) {
model.add(new FirstWiwardStep()});
}
// Keep adding the rest of the steps
...
if(WizStep.STEP_N.getNum() >= startStep.getNum()) {
model.add(new NthStep());
}
init(model);
}
}
Maybe a better approach is to create your own parent intelligent wizard
step that will skip itself in the init() or onInit() method till it get to
the Active step then you could build your model as normal.
Have fun.
