Re: Instance Variables in Web Page of Wicket Portlet
On Mon, 25 Aug 2008, prabha77 wrote: If instance variables are defined in a subclass of WebPage, would they be thread-safe? For convenience, we're passing a reference to the parent page to it's child components. We are seeing these instance variables overwritten by other users and then those changes are reflected in the original user's session. Is it incorrect to define any instance variables in a WebPage? I don't know about portlets, but normally the Component (including (Web)Page) instances should be specific to a session. So this sounds like strange. Recently some session leakage problems have come up on the mailing list, and something was fixed in version 1.3.4. You might want to search the mailing list to find the whole discussion.

DataTable - tfoot before tbody?
Hi,
I have a customized DataTable.
Here's what we have in the constructor:
super(id, columns, dataProvider, rowsPerPage);
add(HeaderContributor.forCss(/eurekify/style/EurekifyDataTable.css));
add(new AttributeAppender(class, true, new
Model(eurekifyTable),
));
addTopToolbar(newNavigationToolbar());
addTopToolbar(newHeadersToolbar(dataProvider));
addBottomToolbar(new NoRecordsToolbar(this));
addBottomToolbar(new EurekifyBottomTableToolbar(this,
rowsPerPage,
modalWindows,
showSelectRecordsPerPage));
add(new AttributeAppender(class, true, new
Model(emptyTable), ) {
private static final long serialVersionUID = 1L;
@Override
public boolean isEnabled(Component component) {
return dataProvider.size() == 0;
}
});
More info:
newHeadersToolbar(...) returns AjaxFallbackHeadersToolbar (which is
HeadersToolbar)
newNavigationToolbar(...) returns StyledAjaxNavigationToolbar which inherits
from AjaxNavigationToolbar (which is NavigationToolbar).
EurekifyBottomTableToolbar inherits from AbstractToolbar.
When I look at FireBug, I see that the tfoot section of the table is BEFORE
the tbody.
Has anyone encountered this?
Do I do something wrong?

Property that references property
Hi!
Sometimes I think it would be useful to refer properties from
properties. Example:
WicketApplication.properties -file:
myProperty=The maximum width allowed is ${property.maxWidth} pixels
property.maxWidth=30
Now I would like to use the maxWidth simultaneously for both
validation purposes and to display an instruction message that changes
according to the parameter maxWidth. But Wicket does not seem to have
the smarts of referring to a property from within a property.
Has someone figured out a simple workaround trick or pattern to
accomplish this, or does it require a serious add-on 'hack' on Wicket?

Re: Property that references property
Also just found this in StringResourceModel javadoc... So I guess you can
certainly do what I mentioned earlier.
* liparameters - The parameters parameter allows an array of objects to
be passed for
* substitution on the found string resource (see below) using a standard
* codejava.text.MessageFormat/code object. Each parameter may be an
ordinary Object, in which
* case it will be processed by the standard formatting rules associated
with
* codejava.text.MessageFormat/code. Alternatively, the parameter may be
an instance of
* codeIModel/code in which case the codegetObject()/code method
will be applied prior
* to the parameter being passed to the
codejava.text.MessageFormat/code. This allows such
* features dynamic parameters that are obtained using a
codePropertyModel/code object or even
* nested string resource models.

Make sure your HTML enclosing the table is proper XHTML and try it in IE or

Hi, As part of my requirement, I have to create a custom url coding strategy for bookmarkable pages. The URLs should be like e.g. http://domain.com/somestr_[id].html. The problem I am facing is all the bookmarkable pages need to have a static mount string, which makes the URL to be http://domain.com/mount/somestr_[id].html. This sort of dictates using some other solution such as (urlrewrite or apache mod_rewrite) on top of custom url coding strategy. Digging little into the code seems like it may be possible to relax the requirement of letting only 1 page be mounted on / and let the matches() and encode()/decode() methods of the coding strategy generate proper internal request target urls.

@SpringBean injection -- why pretend?
Dear All --
I was having an issue with @SpringBean injection -- my dao class was not
initialized properly with the dependent beans. I spent some time
exploring internals of CGLib and Spring Injections and then a thought
struck me: how really helpful is this injection?
Consider this code:
class MyPage extends Page {
...
@SpringBean
MyDAO dao;
...
}
vs. this code:
class MyPage {
...
MyDAO dao= Locator.find(myDAO, MyDAO.class);
...
}
The Locator is a pretty straightforward guy who pulls
ApplicationContext out of thin air^ThreadLocal variable and looks up
on it, see the example code below.
The former uses annotations, CGLIB and delicate injection. The latter
uses nothing and is a lot simpler and robust. Aside from marginal
savings in typing I couldn't find any advantages of the former approach.
Can you?
Unless convinced otherwise, I am going to skip the @SpringBean
altogether and use the Locator thing in my application.
Thanks,

Re: @SpringBean injection -- why pretend?
Are you planning on serialising your DAOs?
No -- I mark them as transient.
How will you mock out your Locator for unit tests?
I didn't provide the implementation in the parent, but it's pretty obvious:
/** Use for unit tests */
public static class MockLocator extends Locator {
HashMapString, Object map= new HashMapString, Object();
Object find(String name) {
return map.get(name);
}
public void put(String name, Object value) {
map.put(name, value);
}
}
class MyTest extends TestCase {
void setUp() {
MockLocator mockLocator= new MockLocator();
MyDAO dao= new MyDAO(...);
mockLocator.put(dao, dao);
Locator.register(mockLocator);
}
}
Hope this makes sense.

Re: @SpringBean injection -- why pretend?
The problem is keeping a reference to the service.
Right, actually I skipped the transient keyword I use in my code:
class MyPage {
...
transient MyDAO dao= Locator.find(myDAO, MyDAO.class);
...
}
transient prevents the field from being serialized.
You might be good
enough to understand that, but how good do you trust your co-workers,
and even new members joining your team?
So, I will have to tell them to use the above pattern, just like telling
them to use @SpringBean?
Regardless, it seems that every engineer working with Wicket have to hit
their serialization bump one day, as you hint in your book. We'll find
out :-)
Thanks for the book by the way. It made me go much faster.

Re: @SpringBean injection -- why pretend?
If you mark that DAO as transient, what will happen after deserialising your
page? Will you implement your own serialisation strategy to go with your
home-made dependency injection mechanism?
Are you just trying to avoid using Spring or do you just not like
@SpringBean and the underlying Wicket proxying beneath the covers? FYI, it
has worked fine for us.
You may end up with a solution that is quite convoluted, hard to
learn/maintain, less elegant and hard to get just right in all cases (for
example testing, serialization/deserialisation etc...). But at the end of
the day, one of the key features of a framework like Wicket is that you can
do anything that Java lets you - so the choice is always yours.

Re: Browser multiple tabs and page expired/class not found issues
By versioning you mean assigning serial version id? if yes - I have declared serialVersionUID for all the classes that are serializeable. I do not update the version # when I change the page - not sure if that is what you mean by versioning my pages. This errors occurred for the same session (IE multiple tabs seem to share the session for some reason). so I would think whatever version # was for the tab - have to be same for both.

Actually, I was doing setResponsePage(new BookmarkablePage(new Pagepamaeters()) on the form submission. I realized later I shouldnt, since this makes the URL to have ?wicket:interface.. Shouldnt mounted bookmarkable pages - even though they are created using constructor have the mounted url format? I will try to create a sample app to reproduce the issue.

Re: Possibility of mounting multiple pages on / and Custom URL coding strategy?
To implement resolve() for requestcycleprocessor, unfortunately I cannot get list of mounted pages to resolve them to respective requesttargets since IRequestTargetMountsInfo is optional and CryptedUrlWebRequestCodingStrategy doesnt implement it. Is there a way to get mount list which works no matter what requestcodingstrategy is? Note: my urls have to be http://domain.com/somestr_id.html and I have to use regular expressions to parse somestr_id to get the request target as there is no mount path.

Re: @SpringBean injection -- why pretend?

Oops, I didn't know that :-$
In this case, I will need to use extra indirection; still pretty
straightforward:
class MyPage ... {

LocatableMyDAO dao= new LocatableMyDAO(myDAO, MyDAO.class);
...
dao.get().findSomething()
};
I have JUnit test that successfully tests the

is interest.

Right, actually I skipped the transient keyword I use in my code:

transient prevents the field from being serialized.
You might be good
enough to understand that, but how good do you trust your co-workers,
and even new members joining your team?
So, I will have to tell them to use the above pattern, just like telling
them to use @SpringBean?
Regardless, it seems that every engineer working with Wicket have to hit
their serialization bump one day, as you hint in your book. We'll find
out

Thanks for the book by the way. It made me go much faster.

Igor --
Here is what I had:
class Bean1 {...}
class Bean2 {
public Bean2(Bean1 bean1) {}
}
Spring config:
bean name=bean1 class=Bean1/
bean name=bean2 class=Bean2
constructor-arg name=bean1 ref=bean1/
/bean
class MyPanel extends Panel {
...
@SpringBean Bean2 bean2;
...
}
The problem was that bean2 could not initialize, it was looking for
empty constructor which the class didn't have and failed. I tried using
property initialization but ended up with null value for Bean1 and
methods of bean2 were failing with NPE.
I had another group of beans like that in the program which was working
fine.
Another thing that got me scared was that the initializer for Bean1 got
called twice: once on application initialization and once on
initialization of the page. I spent some time within initialization
code, CGLib and such and figured I needed much more time to figure out
what's happening there.
I will report more on this problem when I have time to assemble test
case. I have workaround now and I am on to the next problem -- see my
separate email.

Re: AjaxFallbackDefaultDataTable - goto page number on return from another page
Anyone know how to solve this?
Thanks.
steviezz wrote:
Wicket 1.3.4.
I have a Page (ThingListing) containing an AjaxFallbackDefaultDataTable -
created like:
private WebMarkupContainer listContainer = new
WebMarkupContainer(listContainer);
private MySortableDealProvider dataProvider;
private Thing thing = null;
public ThingListing(PageParameters params) {
// this is a reload from the CRUD page
if (params != null) {
setThing(getThingManager().findById(params.getString(thingId)));
}
// else load everything
...
dataProvider = new SortableDealDataProvider(getThingManager(), thing);
String sort = params.getString(sort);
Boolean isAscending = params.getBoolean(ascending);
dataProvider.setSort(sort, isAscending);
...
listContainer.add(new AjaxFallbackDefaultDataTable(mything, columns,
dataProvider, TABLE_ROWS));
I add an AbstractColumn to the AjaxFallbackDefaultDataTable to handle
forwarding to a page to do CRUD work on the selected item from the table -
like :
columns.add(new AbstractColumn(new Model(Edit)) {
public void populateItem(Item cellItem, String
componentId, IModel
model) {
cellItem.add(new ActionPanel(componentId,
model));
}
public String getCssClass() {
return edit;
}
});
class ActionPanel extends Panel {
public ActionPanel(String id, IModel model) {
super(id, model);
add(new Link(edit) {
public void onClick() {
Integer thingId = ((Thing)
getParent().getModelObject()).getId();
PageParameters params = new
PageParameters();
params.put(thingId, thingId);
params.put(sort,
dataProvider.getSort().getProperty());
params.put(ascending,
dataProvider.getSort().isAscending());
setResponsePage(ThingEdit.class,
params);
}
});
}
}
Note - I am attempting to pass the id of the selected row in the table,
plus the sort column, and the ascending direction to the CRUD page.
The ThingEdit CRUD page takes all the page params from the ThingListing
page, does normal CRUD work, then passes back all the params back into the
main listing page constructor so that when the listing page reloads, it
maintains its state (main selection criteria, sort column, sort order)
from the page the user selected before triggering the CRUD page - eg:
public class ThingEdit {
private PageParameters pageParams;
public ThingEdit(PageParameters p) {
pageParams = p;
...
}
...
private void addCancelButton(Form form) {
Button cancel = new Button(cancelbutton) {
public void onSubmit() {
setResponsePage(ThingListing.class, pageParams);
}
};
cancel.setDefaultFormProcessing(false);
form.add(cancel);
}
However, I can't work out how to go back to the page number that the user
was on before he loaded the CRUD page. That is, if the user was on page 3
of 20, then after clicking a record to edit goes to the CRUD page, then he
goes back to the listing the correct order and sort are maintaine, but
he's always at page 1 of 20 instead of page 3.
I have tried manually setting the ThingSortableDataProvider.iterator()
first and count and with additional page params - but this just ends up
with it being called twice - once with my page params, and again by the
default 0 and count.
So, any way to make this work?
I think am probably still missing the point with Wicket (can't really get
my head around Models) and revert to attempting to use page params and
manually adding to session to pass data from one page to another and back
again.

If you mark that DAO as transient, what will happen after deserialising
your

home-made dependency injection mechanism?
Are you just trying to avoid using Spring or do you just not like
@SpringBean and the underlying Wicket proxying beneat h the covers? FYI,
it
has worked fine for us.
You may end up with a solution that is quite convoluted, hard to
learn/maintain, less elegant and hard to get just right in all cases (for
example testing, serialization/deserialisation etc...). But at the end of
the day, one of the key features of a framework like Wicket is that you
can
do anything that Java lets you - so the choice is always yours.

No -- I mark them as transient.
How will you mock out your Locator for unit tests?
I didn't provide the implementation in the parent, but it's pretty
obvious:
/** Use for unit tests */
public static class MockLocator extends Locator {
HashMapString, Object map= new HashMapString, Object();
Object find(String name) {
return map.get(name);
}
public void put(String name, Object value) {
map.put(name, value);
}
}
class MyTest extends TestCase {
void setUp() {
MockLocator mockLocator= new MockLocator();
MyDAO dao= new MyDAO(...);
mockLocator.put(dao, dao);
Locator.register(mockLocator);
}
}
Hope this makes sense.

Dear All --
I was having an issue with @SpringBean injection -- my dao class was
not
initialized properly with the dependent beans. I spent some time
exploring internals of CGLib and Spring Injections and then a thought
struck me: how really helpful is this injection?
Consider this code:
class MyPage extends Page {
...
@SpringBean
MyDAO dao;
...
}
vs. this code:
class MyPage {
...
MyDAO dao= Locator.find(myDAO, MyDAO.class);
...
}
The Locator is a pretty straightforward guy who pulls
ApplicationContext out of thin air^ThreadLocal variable and looks
up
on it, see the example code below.
The former uses annotations, CGLIB and delicate injection. The latter
uses nothing and is a lot simpler and robust. Aside from marginal
savings in typing I couldn't find any advantages of the former
approach.
Can you?
Unless convinced otherwise, I am going to skip the @SpringBean
altogether and use the Locator thing in my application.
Thanks,

Re: Crystal Report
Hello, Yah, Cryastal Report has some concurrent process licensing issue. i just encountered it in the project where I'm supporting to. It is such pain in the ass that we don't know what going wrong until we found that freaking CPL issue. Nwei, im encouraging the PM of next project I'm into to use jasper instead but client is using crystal report for their current app's. So there is a struggle between. But just in case we use crystal report, i might post again for help. Thanks a lot. Cheers. msc65jap wrote: Yeah, I have with a Wicket app. that serves Crystal Reports XI reports. I scrapped using its J2EE business connector and, instead, wrote the reports in PDF format to the local filesystem and emailed them to user. I would recommend doing this asynchronously because of the expensive I/O costs. You don't have to email them but I had to do as it was my use case. Crystal Reports API is a big pain in the backside so good luck! Best, James.

Re: @SpringBean injection -- why pretend?

Does the trace at the end of this note, in my PS, look familiar?
Now try the following code (notice the addition and use of the IBean2

your component (a Page in this case) the interface. If you can't do that on
your project (eg Bean2 is from a 3rd party library) then we'll have to take

Re: @SpringBean injection problem
this isnt really wicket-specific. this is just something you need to
be aware of when dealing with IOC containers. if you wanted to eg have
transactional methods on this bean you would run into the same problem
as spring would try to create a proxy of your class to manage
transactions (unless you were using direct bytecode weaving...)

Re: @SpringBean injection problem went away
Igor and all --
I also had this problem when using default constructor and
initialization by properties.
OTOH I have Hibernate DAO classes using transactions, and they work fine.
Good news, the problem went away when I broke the Bean1-Bean2 chain
because of application reasons. If/when the problem reappears, I will
try to report in more detail.
Thanks everyone for your help,

I have no idea. Martijn and I (or rather, my parents in Holland) received a bunch of paper copies, so the actual book *is* out.
