Re: Wizard help
I am just having trouble with the move from Step 1 to Step 2. I assume
the success logic would be implemented in the onFinish() method of my
ForgotPasswordWizard
You can use an listener to implement success logic, onFinish will to be
called when Finish button get pressed

RE: Wizard help
Do I override the onFinish() method of my wizard or do I add a listener
to my wizard and put the logic there? It looks like the wicket Wizard
that I am extending already implements the IWizardModelListener
[according to the java doc] This will allow me to perform logic needed
when the wizard finishes.
I still don't know how to perform logic between step 1 and step 2.
Flow is:
Step 1 = ask for username
Step 1 = press next ??
Look up username in db and get additional info ??
Step 2 = present additional info for edit ??
Step 2 = press Finish
Update the db and set response page to send the user on their way
Do I use the onActiveStepChanged() method and use getActiveStep() to see
what step I am coming from and do my lookup if the active step is 1?
The examples don't show a good example of a wizard that uses data from
one step to present additional information in another step. Otherwise
the examples are very good.
Thanks.

Re: Wizard help
Hello All, Am new to wickets and trying to learn a few things. To do that am trying to build a web application that a user can post a exam and a responder can answer that exam. So far I have managed to Post a set of questions for a exam into the database. my problem is how to answer those questions. A single exam can have 3 different question types Objectives, short answers and phrase match. Each of this have different forms of interface for responding to it. If there were only 3 questions, one of each type I would just have 3 Wizard Steps, but the number of questions can vary depending on the exam. I would like to reuse the steps for each question type when needed (Have only 3 predefined steps). Can someone guide me on this or point me to a thread that can do the same. A suggestion of an alternate solution is also welcome. Thanks Stephen
Re: Wizard help
I haven't had time to nice it up but here is a class that does this.
Its a wizard that interviews the user based on pre-configured
questions in the database. There are 3 'types' of questions in this
app I wrote earlier this year (Text Field, Text Area and File) and
there can be any number of each type in each defined interview
process. The app was a website configuration engine essentially. The
user would select a template and the template would have
'Configuration Definitions' associated with it. The app would ask the
user for each of these defs what their answer was.
This example has all of the ugly data access stuff so you should get a
good idea how I pull the data in and add it to the model. This is not
shrinkwrap but just an example.
This is ugly but it should give you the idea:
