Access to administrators would always be restricted to certain roles. Whether or not approval is required for an item by an administrator would also be configurable. Furthermore, access restrictions could also be narrowed down by the content itself. (e.g. only viewable by registered users). Each component would generate events upon use, allowing other functionality to be implemented on top of it (such as notification and statistics). Persistence for components would be pluggable with Hibernate as an implementation provided out of the box. Of course, we could be more ambitious and go directly for JSR-170 but perhaps JSR-170 would simply be an implementation of persistence. Does a project like this already exist or should I roll my own?

Re: [Wicket-user] wicket CMS type components...
JackRabbit looks very interesting, I'll have to download and play with it. I'm not convinced it's ideal for every application though, maybe let the plug-in decide what persistence method it wants/needs? Your other points are well taken as well. I assume there will be a lot of rewrites to fix those issues before anything would be finalized.

Re: [Wicket-user] Captcha
For the couple of forms I need it for this is great. I may look at making a component later, I've always meant to learn. Ajax is not really necessary. I probably wouldn't be using it at all expect I've been blown away with how easy it is to add and how much it boosts perceived performance. I have to say, moving an older 1.1 app to 1.2 (I know, I waited long enough...) that it's reduced the number of lines of code and improved functionality/performance all around. Impressive job, can't wait to see what 2.0 brings. Thanks, Troy On Thu, 2006-06-15 at 11:48 -0700, Eelco Hillenius wrote: Very welcome. I figured it was a good example to have.

Re: [Wicket-user] Page Lifecycle
Thank You! This clears up a lot of confusion, and is exactly what was
happening. Shortly after my last message I tried checking for a null
session object and everything worked, though I expected a run time error
due to the missing panel.
User user = ((VSecureSession)getSession()).getUser();
if(user != null){
add(new EventListPanel(eventList, user.getId()));
//add other session dependent panels
}
So what is happening is:
1. Page is constructed, skipping session dependent panels
2. checkAccess() is called redirecting to signIn page
3. User signs in and the session is created
4. Original page is re-constructed, this time with a session
5. Original page is rendered
Not the most elegant solution, but for now so long as it works I'm
happy. I'd be interested in any other approaches in the future though.
Thanks,

Troy,
I think you are confusing constructing a page with rendering a page.
First a page is being constructed (that's where you are getting the
exception I believe)
then checkAccess is being invoked, and later the page is being rendered..
I'm having similar problems with protected pages - sometimes the
construction depends on session information but you don't have a valid
user session until checkAccess returns true.
So, what you could do is, skip the construction if the user is not
authenticated ( the page is not going to be rendered anyway).
Or, create your page in a such a way that session based decisions are
delayed until render time.
Or, don't use wicket's authentication features...
I consider this more a design issue because the workarounds are not
satisfying for me.
I'm currently experimenting with a different auth approaches...
Better ideas anyone?

Thanks for the reply, I'm using RC2, and my app is originally based on
one of the CD apps in contrib-examples (the one with annotations) from

In my base page, I redirect to a sign-in page which adds the user object
to my session. I then try to use this object in a page which extends the
base page.
If I link directly to a page (via setHomePage() or bookmark) that
accesses the session, my session user object is still null and the page
fails to render (due to the null pointer exception in my panel code).
If I first link to a page that doesn't use the session variable, and
_then_ link to a page that does everything works as expected. So it
seemed as though checkAccess() wasn't being called until after the page
rendered.
I'll take a look with more alert eyes in case there are any lingering
issues with the demo code (or at least any I can understand:). I'm also
going to try catching the null exception, I expect they won't see data
on the first page they visit but at least it won't crash.
Here is a more complete version of the relevant code in case it helps...
From base page:
protected boolean checkAccess()
{

admin); //DEBUG
boolean signedIn = ((VSecureSession)getSession()).isSignedIn();
if(!signedIn){
redirectTo(newPage(SignIn.class));
}
return signedIn;
}
From my session:
public final boolean authenticate(final String username, final String
password)
{
if (user == null)
{
inUser = ((VSecureRequestCycle)
getRequestCycle()).getDao().getUser(username);
if((in.getPassword()).equalsIgnoreCase(password)){
this.user = in;
return true;
}
return user != null;
}
And the line in the sub page (which causes the null pointer):
Long userId =
(((VSecureSession)getSession()).getUser()).getId();
add(new EventListPanel(eventList, userId));

When my user logs in, checkAccess() redirects them to a sign in page which adds their information to the session for later access. This works well until I try to go directly (before login) to a (Bookmarkable) page that uses this session information. After investigating it seems that the entire page is rendered before calling checkAccess()? Which in my case leads to numerous null pointer exceptions since the session data is uninitialized. I've tried overriding various methods to call checkAccess() earlier in the process but without any luck. I'm sure there is a very simple answer, but it's getting very late and I've been at this for a while so any help would be _greatly_ appreciated.

if necessary rather than select from a pre-instantiated list.

RE: [Wicket-user] Creating Embedded Object via Form
This is ultimately what I want. The Client object will have a collection
of addresses, invoices and other objects. The user can view these
objects and add new ones.
- I can create a form to create a new Client.
- I can create a form to add an address to an existing Client (at least
I think I can;)
- I can't create a form to create a Client and add an Address at the
same time. Right now I get bind errors if I add fields that aren't
properties of the Client object itself.
I suspect the solution lies with the property model. My current code
references Client directly:
IModel clientFormModel = new CompoundPropertyModel(new Client());
But I don't have a clear enough understanding of how Compound and Bound
property models work.

In the end, (Bound)CompoundPropertyModels are IModels. IModel just has
get/setObject, where you can implement anything you want, including
object creation etc.
CompoundPropertyModels are meant to make your life easier in the sense
that you need less code to acchieve model/property binding. The basis
however, is PropertyModel. WIth PropertyModel you can bind anything
you want, as long as it is a valid two-way Ognl expression.
IModel clientFormModel = new CompoundPropertyModel(myClient);
setModel(clientFormModel);
add(new TextField(address.streetAddress);
is the same as:
BoundCompoundPropertyModel clientFormModel = new
BoundCompoundPropertyModel(myClient);
setModel(clientFormModel);
add(clientFormModel.bind(new TextField(nonImportantName),
address.streetAddress));
is the same as:
add(new TextField(nonImportantName, new PropertyModel(myClient,
address.streetAddress));
Now, the problem with your code is that the address is null by
default. Ognl doesn't like that, and will throw an exception. There
are a zillion ways to tackle this, including patching Ognl, patching
PropertyModel, etc, but the simplest way to go here is to make sure
you allways have a non-null address property. Either by declaring that
property like 'protected Address address = new Address;' - your ORM
will overwrite that field when it does have a saved value - or lazily
create an instance in your getter - in which case you must make sure
the getter is not by-passed by any code generation your ORM might do
for you.
I don't think you need the converter; it will work in some cases, and
for some custom object they can be very convenient/ elegant, but in
this case, the fact that your property can be null and Ognl doesn't
try object creation is the real issue.

Subject: [Wicket-user] Creating Embedded Object via Form
This isn't the brightest question I've ever asked, I feel I'm missing
very obvious. But I don't see an answer in the examples/wiki so here
goes...
I'm wondering how to handle. So for instance if I have a Client object
which has one or more Address objects as members, how can I create a new
client using a single form?
I've looked at the cdapp example where Categories are linked to Albums,
what I want is similar except I'd like to create Categories on the fly
if necessary rather than select from a pre-instantiated list.
form wicket:id=form action=
Name:
input type=text wicket:id=firstNamebr/
Street Address:
input type=text wicket:id=address.streetAddressbr/
input type=submit value=Add Client/
/form
@Entity
public class Client implements ComparableClient {
protected Long Id;
protected String Name;
protected Address address;
/*typical getters/setters below */
}
@Entity
public class Address implements ComparableAddress {
protected Long Id;
protected String streetAddress;
/*typical getters/setters below */
}
Any help or pointers in the right direction greatly appreciated...
Thanks,

RE: [Wicket-user] Creating Embedded Object via Form
I may have celebrated a bit soon. While the form renders and submits
without errors, browsing to a page with a ListView of Client objects
shows that no data has been entered. All simple Client properties are
empty, and the address field contains an object reference with all null
values.
Attempting to edit this entry causes a Hibernate exception:
org.hibernate.TransientObjectException: object references an unsaved
transient instance - save the transient instance before flushing:
com.alluvion.test.model.Address
Also, if I try to go to another page in my form onSubmit() using
setResponsePage() the same Hibernate exception is thrown.
This happens whether I create a new Address where it is declared or in
the getAddress method. My app is originally based on the cdapp demo
which uses Hibernate 3 and annotations.
Any thoughts greatly appreciated, I'm going to keep looking through the
Hibernate docs and maybe test to see if I can persist any embedded
objects, not just the ones at creation time.
Thanks,
Troy

Return address;

CompoundPropertyModels are meant to make your life easier in the sense
that you need less code to acchieve model/property binding. The basis
however, is PropertyModel. WIth PropertyModel you can bind anything
you want, as long as it is a valid two-way Ognl expression.
IModel clientFormModel = new CompoundPropertyModel(myClient);
setModel(clientFormModel);
add(new TextField(address.streetAddress);
is the same as:
BoundCompoundPropertyModel clientFormModel = new
BoundCompoundPropertyModel(myClient);
setModel(clientFormModel);
add(clientFormModel.bind(new TextField(nonImportantName),
address.streetAddress));
is the same as:
add(new TextField(nonImportantName, new PropertyModel(myClient,
address.streetAddress));
Now, the problem with your code is that the address is null by
default. Ognl doesn't like that, and will throw an exception. There
are a zillion ways to tackle this, including patching Ognl, patching
PropertyModel, etc, but the simplest way to go here is to make sure
you allways have a non-null address property. Either by declaring that
property like 'protected Address address = new Address;' - your ORM
will overwrite that field when it does have a saved value - or lazily
create an instance in your getter - in which case you must make sure
the getter is not by-passed by any code generation your ORM might do
for you.
I don't think you need the converter; it will work in some cases, and
for some custom object they can be very convenient/ elegant, but in
this case, the fact that your property can be null and Ognl doesn't
try object creation is the real issue.

This is ultimately what I want. The Client object will have a

- I can create a form to create a new Client.
- I can create a form to add an address to an existing Client (at
least
I think I can;)
- I can't create a form to create a Client and add an Address at the
same time. Right now I get bind errors if I add fields that aren't
properties of the Client object itself.
I suspect the solution lies with the property model. My current code
references Client directly:
IModel clientFormModel = new CompoundPropertyModel(new Client());
But I don't have a clear enough understanding of how Compound and
Bound
property models work.

RE: [Wicket-user] Creating Embedded Object via Form
Thanks again, that was it. I'd tried setting the cascade property but
obviously got it wrong...I'm new to annotations as well as Wicket. For
anyone else looking to do this, the successful code is:
//In the Client Object
@ManyToOne(cascade = { CascadeType.ALL })
public Address getAddress() {
if(address == null) address = new Address();
return this.address;
}
public void setAddress(Address aValue) {
this.address = aValue;
}
//In the NewClient.java page
add(new TextField(address.streetAddress));
Many thanks to all who helped!

you should set the cascade of your address relationship to include save,
that way hibernate will persist all the objects in that relationship when
you persist your client object. Otherwise you have to call save on every
instance of new address you add into the collection.
