Re: DataTable's FilterToolbar generics broken
Confused I am not :)
Let me give you three examples...
I. filtering with a subset of properties
This is a class that worked perfectly in 1.4.19:
public class CustomersDataProvider extends
HibernateDataProvider implements
IFilterStateLocator {
@SuppressWarnings("unused")
public static class CustomerFilter implements Serializable {
private Stringname;
private Stringnip;
public String getName() {
return name;
}
public void setName( String name ) {
this.name = name;
}
public String getNip() {
return nip;
}
public void setNip( String nip ) {
this.nip = nip;
}
}
private CustomerFilterfilter= new CustomerFilter();
public CustomersDataProvider() {
super( Customer.class );
setSort("name",
true );
}
@Override
public CustomerFilter getFilterState() {
return filter;
}
@Override
public void setFilterState( CustomerFilter state ) {
filter = (CustomerFilter) state;
}
@Override
public IModel model( Customer object ) {
return new CustomerModel( object );
}
@Override
protected void filter( Criteria c ) {
CriteriaHelper.ilike(c,
"name",
filter.getName() );
CriteriaHelper.ilike(c,
"nip",
filter.getNip() );
}
}
why? Customer is a class with lots of properties. I am unable to
provide proper filtering for all properties so I create a
CustomerFilter having only two properties: name and nip. This way I am
stating to other developers that my IDataProvider filters by two
properties only.
II. filtering date properties
Let's have a Sale entity with "date" property. Dates are usually
filtered by date ranges. So in filter I need startDate and finishDate
with two inputs rather than one (Sale.date). It is impossible if the
filter does not differ from base collection type.
with wicket 1.4.19 it was:
@Getter @Setter
public class SaleFilter implements Serializable {
private DatedateFrom;
private DatedateTo;
private StringcustomerName;
private Stringdescription;
private Statusstatus;
private GroupingModegroupingMode;
}
class SalesDataProvider extends HibernateDataProvider implements
IFilterStateLocator {
private SaleFilterfilter= new SaleFilter();
private final LongcustomerId;
public SalesDataProvider( Long customerId ) {
super( Sale.class );
this.customerId = customerId;
setSort("date",
false );
}
@Override
protected Criteria setupCriteria( Session session ) {
Criteria c = super.setupCriteria( session );
c.createAlias("customer",
"customer" );
return c;
}
@Override
protected void filter( Criteria c ) {
if ( customerId != null )
c.add( Restrictions.eq( "customer.id",
customerId ) );
else if ( !StringUtils.isBlank( filter.getCustomerName() ) )
CriteriaHelper.ilike(c,
"customer.name",
filter.getCustomerName() );
CriteriaHelper.dateFilter(c,
"date",
filter.getDateFrom(),
filter.getDateTo() );
CriteriaHelper.ilike(c,
"description",
filter.getDescription() );
if ( filter.getStatus() != null )
c.add( Restrictions.eq( "status",
filter.getStatus() ) );
if ( filter.getGroupingMode() != null )
c.add( Restrictions.eq( "groupingMode",
filter.getGroupingMode() ) );
}
@Override
public IModel model( Sale object ) {
return new SaleModel( object );
}
@Override
public SaleFilter getFilterState() {
return filter;
}
@Override
public void setFilterState( SaleFilter state ) {
this.filter = state;
}
}
III. filtering with a superset of properties
Lets design a data provider for Order.
How would you create a filter for orders containing a selected
product? Probably so:
@Getter @Setter
public class OrderFilter implements Serializable {
private Date creationStartDate;
private Date creationFinishDate;
private String customerName;
private Long selectedProductId;
}
In this case the filter contains MORE pro
DataTable's FilterToolbar generics broken
I started migrating my code from wicket 1.4.19 to 6. Finally ! :) I found a FilterToolbar bug: Once you were able to create DataTable wrapped inside of FilterForm currently FilterToolbar requires you for those two types to be identical: public FilterToolbar(final DataTable table, final FilterForm form, final IFilterStateLocator stateLocator) It looks like commit 9b3f9ca1df064fe9c6fde64ccc37fecc504b09a6 introduced a bug long time ago and it carried on: - public FilterToolbar(final DataTable table, final FilterForm form, + public FilterToolbar(final DataTable table, final FilterForm form, FilterToolbar constructor should state: public FilterToolbar(final DataTable table, final FilterForm form, final IFilterStateLocator stateLocator) cheers. -- Leszek Gawron - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org

wicket as template engine
I know I could use freemarker, velocity or any other tool. But these
tools require me to create a full blown template model up front as
wicket allows for a bunch of models chained togeter pulling data from
different sources when they are needed.
I have a set of load of panels that create a single Page. The customer
wants me to export page contents to pdf so I thought I could:
1. create a "print" skin for the panels
2. render the panels/page using "print" skin to the external html file.
3. use some html to pdf rendering tool (like flying saucer)
4. serve pdf as with content-disposition: attachment
Everything is easy apart from 1). Can you advise?

Panel factories and @SpringBean
Hello,
Let's say I want to write some UI to edit some complicated configuration
split into multiple entities in multiple maven modules. The UI needs to
have one entry point though. So:
Let's create the UI based on TabbedPanel. Each of the tabs will be
provided by different maven modules by the means of factories:
> public interface JukeboxConfigPanelFactory extends Ordered {
public IModel getPanelTitle();
public Panel getPanel( String id, IModel jukeboxModel );
}
Provided that I have a list of all panel factories (that is an actual
problem!) I can do that:
List tabs = new ArrayList();
for ( JukeboxConfigPanelFactory factory : getPanelFactories() )
{
tabs.add( new
JukeboxConfigPanelFactoryAwareAbstractTab( factory, getJukeboxModel() ) );
}
add( new AjaxTabbedPanel( "tabs", tabs ) );
The problem is: HOW do I get all the panel factories defined in Spring
context?
I cannot do :
@SpringBean
private List factories;
because this is not supported by
org.apache.wicket.spring.injection.annot.AnnotProxyFieldValueFactory.
I could create another spring bean:
public interface JukeboxConfigPanelFactoryManager {
public List getPanelFactoryList();
}
@Component
public class JukeboxConfigPanelFactoryManagerImpl implements
JukeboxConfigPanelFactoryManager, InitializingBean {
private List factoryList;
@Autowired
public JukeboxConfigPanelFactoryManagerImpl(
List factoryList ) {
this.factoryList = factoryList;
}
@Override
public List getPanelFactoryList() {
return Collections.unmodifiableList( factoryList );
}
@Override
public void afterPropertiesSet() throws Exception {
Collections.sort( factoryList,
new OrderComparator() );
}
}
so now I am able to get all factory implementations in one place:
List tabs = new ArrayList();
for ( JukeboxConfigPanelFactory factory :
panelFactoryManager.getPanelFactoryList() ) {
tabs.add( new
JukeboxConfigPanelFactoryAwareAbstractTab( factory, getJukeboxModel() ) );
}
add( new AjaxTabbedPanel( "tabs", tabs ) );
But now the JukeboxConfigPanelFactoryAwareAbstractTab will fail
miserably at serializing as only the manager has been wrapped with a
proxy and not the factories underneath.
How can I approach the problem using current state of wicket-spring
module? I haven't found a way to wrap the "factory" beans with proxy
manually.

yes ... your modal window has to be put into a form, so the panel's form
is nested:
Example:
public class TrackerGroupsPanel extends Panel {
@SpringBean
private FleetServicefleetService;
@SpringBean
private TrackerService trackerService;
private ModalWindow modalWindow;
protected FeedbackPanel feedback;
public TrackerGroupsPanel( String id, final IModel model ) {
super( id, model );
setOutputMarkupId( true );
add( new Form( "form" ) {
{
add( feedback = new FeedbackPanel( "feedback" )
);
feedback.setOutputMarkupId( true );
add( modalWindow = new ModalWindow(
"modalWindow" ) );
modalWindow.setWindowClosedCallback( new
WindowClosedCallback() {
@Override
public void onClose( AjaxRequestTarget
target ) {
target.addComponent(
TrackerGroupsPanel.this );
}
} );
add( new AjaxLink( "registerGroup",
model ) {
@Override
public void onClick( AjaxRequestTarget
target ) {
modalWindow.setTitle( "Nowa grupa
pojazdów" );
modalWindow.setContent( new
TrackerGroupPanel( modalWindow.getContentId(), Model.of( new TrackerGroup(
getModelObject() ) ) ) {
@Override
protected void onSave(
AjaxRequestTarget target ) {
modalWindow.close( target );
}
} );
target.addComponent( feedback );
modalWindow.show( target );
}
} );
[...]
then you will hit another bug if your form starts using ajax onchange
notifications ... but that is another tale :)

On 2010-10-07 04:51, Mauro Ciancio wrote: Hello everyone, I'm using spring in one wicket project and I'm lost about how the proxy stuff works. I've realized that the fields marked with @springbean are injected when the component injection listener runs. Also, I've looked in AnnotProxyFieldValueFactory.class to find out how the bean proxy is created and how it can be serialized. Now, this is my issue. The page is created by wicket, the injection is done and I have the bean ready for use. If the page is serialized, the bean will be reconstructed using the bean factory (through the proxy). But, somehow when I click a non bookmarkable link in my page, the bean is never reconstructed and I have the previous reference to the bean (I mean, the same object). Is this the correct behavior? Shouldn't this bean be reconstructed when another request arrives? BTW, I've defined all the beans with prototype scope, so it's not a spring issue. AFAIR the once the bean is looked up from spring it is being cached by AnnotProxyFieldValueFactory itself. So using prototype scope will not work anyway: either way you always get a fresh bean (so you cannot keep state) or you will always get the same bean (even worse if the bean is stateful). You probably should convert your code to using singleton beans and pass appropriate state from wicket component itself. lg -- Leszek Gawron http://lgawron.blogspot.com - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org

I'm using Spring to inject the Entity Manager into my DAO-ish DB logic wrapper

There is a "ItemsPage" that lists items from a database table using a DataView
with a
SortableItemProvider (SortableDataProvider) and a PagingNavigator. It
also has a member
AppDAO that is a @SpringBean. The page uses a SortableItemProvider
(SortableDataProvider) to
provide data for the DataView.
The SortableItemProvider receives an AppDAO instance from the page (as a
constructor parameter)
during the page constructor and stores it as a member variable. It then passes
the AppDAO off to
the DetachableItemModel (DetachableLoadableModel) when it creates them.
public class MyDataProvider ... {
@SpringBean
private AppDAO appDao;
public MyDataProvider() {
InjectorHolder.getInjector().inject( this );

and you'll be fine. You do not have to pass it from the page.
Injector injects a serializable proxy instead of the bean directly.

Lets say there are on the page:
- some panels has it's own FeedbackPanel (properly filtered)
- some panels with no FeedbackPanel
Is there a possibility to put a "global" FeedbackPanel on the page and
put in it ONLY the messages that have been filtered out by every "local"
FeedbackPanel?
Or the other way around: global FeedbackPanel filters out anything that

No no .. This is exactly the opposite of what I want.
I cannot setDefaultFormProcessing to false for Wizard buttons - some
screens may need other settings.
I need the nested form validators NOT to fire when pressing wizard
navigation buttons.

Pressing wizard "Next" button makes addContactForm validate which raises

Is there a way to fire form/field validators only if a specific button

Is this a bug? Or is there anything obvious I missed?
I stumbled upon exactly the same poblem. The only thing I can tell you:
you don't need wicket:enclosure in your case. Simply remove the tag and
as Link.isVisible returns false it will not be rendered.
If you put anything else apart from into wicket:enclosure you
should see correct behavior.
This probably IS a bug. File a JIRA request for that.

The situation that I'm dealing with most commonly is where I'm dealing

case, to create a proxy for each object in the object graph which is
not serializable until you get down to the actual data (i.e.
primitives, Strings, etc.) which is serializable. The proxies would
have to keep track of whatever information they need to de-serialize
themselves (e.g. class name and constructor). It seems like this has
not been implemented, but do you think it is possible to do so?
That sounds cumbersome too :)
If the objects are in fact serializable, why can't you make
them Serializable?
As I am learning AspectJ lately I try to solve every problem with it :)
it turns out you could weave DTOs you have no control over to implement
Serializable interface:
public aspect SerializerImplementer {
declare parents: ProductDTO implements Serializable;
declare parents: ContractorDTO implements Serializable;
declare parents: InvoiceDTO implements Serializable;
}
You can do it once and have no problem with it ever again...

messages. That's crazy !:)
jWeekend wrote:
Leszek,
Thank you asking such a deep question ;-)
We may not all agree, but in the end, at least you have been offered around
87 well-intentioned solutions you can ask your customer to choose from; that
will teach them to request such complex features and fuctionality!
I was really blown by the amount of approaches you all presented. Thank
you for all of them.
Some answers:
1. Dave wrote:
A slightly different approach: I would talk with the customer again, because
this is a really stupid (excusez le mot) requirement. I hope you understand
their motivation, possibly some legacy system that depends on uppercase
information? Maybe the problem can be shifted to that legacy system that
uppercases all data read from the database?
I thought so too but actually it's not that stupid after all. The
customer has to enter A LOT of names, addresses etc. It speeds things up
not to have to think about Proper Word Capitalization. Anything you type
in always looks good.
2. I wanted to go with most non invasive way to do it. That is why I like:
public class UpperCaseBehavior extends AttributeAppender
{
private static final long serialVersionUID = 1L;
public UpperCaseBehavior()
{
super("style", new Model("text-transform: uppercase"), ";");
}
@Override
public void bind(Component component)
{
super.bind(component);
component.add(new AttributeAppender(
"onkeyup", new Model("this.value = this.value.toUpperCase()"),
";"));
}
}
especially used with some nasty logic that would apply the behavior to
every string field.
This is why I find this:
public void setFoo(String foo) {
this.foo = foo == null ? null : foo.toUpperCase();
}
really ugly. Remember that I have to apply this for 99% of my domain model.
3. Igor, will this work:
class uppercasetextfield extends textfield {
public void updatemodel()
{
final String str=getconvertedinput();
setdefaultmodelobject((str==null)?null:str.touppercase());
}
}
If the form model is a loadable detachable model?
The solution I chose:
@UpperCased
@Entity
@Table(name = "usr")
@Inheritance(strategy = InheritanceType.JOINED)
public class User extends Persistent {
private boolean active = true;
private String code;
@NormalCased
private String username;
@NormalCased
private String password;
private String firstName;
private String lastName;
private Set roles = new HashSet();
private String mobilePhone;
private String workPhone;
private String colour;
> }
and:
public aspect Uppercaser {
pointcut setString( String value ) : ( ( set(String (@UpperCased *).* )
&& set(!...@normalcased String *.* ) )
|| set(@UpperCased String *.* ) )
&& args( value );
void around( String value ) : setString( value ) {
proceed( StringUtils.upperCase( value ) );
}
}
because:
1. I decided that the uppercasing should available for junit
tests/command line tools etc.
2. It introduces the least changes into existing code.
3. It allows me to get rid of uppercasing just by recompiling the domain
model library without the aspect (if ever my customer came back to
"sanity").
It feels like I'm introducing way too complicated tool to solve an easy
task (maybe judging by the number of the posts - not that easy after
all), but what the hell...
Thank you for all posts. You are by no means one of the most helpful and
vigorous OS community there is.
PS. I laughed almost to tears reading some posts. Very refreshing :)

Uppercasing inputs
Hello,
one of my customers has this weird requirement that all data should be
input/shown uppercase. I can easily add
input {
text-transform: uppercase;
}
to my css rules, but this does not change the fact that data written
into database will still be case sensitive.
How can I create a behavior for TextField so that the dat is uppercased
before being written to the model?

I think, in my opinion, that the approach of declaring the Form as an inner class makes the code more "dirty". I mean, the Page class grows a lot and by inspecting the code is hard to understand at a first glance the scope of each entity and field. So I prefer to declare the Form as a top class instead inner class. Is there any reccomendation that denies such thing? It's probably a matter of preference and how big your form code actually is.

}
Now the problem:
the links created for clicks on table row look like this:
http://localhost/app/properties/wicket:interface/:3:properties:filterForm:dataTable:rows:2::ILinkListener::/
while the url for "normal" Link is:
http://localhost/app/properties.3.2?wicket:interface=:3:properties:filterForm:dataTable:rows:3:cells:3:cell:edit:2:ILinkListener::
Clicking on the table row makes no redirect. Usually there is a redirect
to: http://localhost/app/properties.3.2
When I hit refresh I get:
WicketMessage: unable to find component with path
properties:filterForm:dataTable:rows:5 on stateless page [Page class =
eu.org.squash.appcomponents.properties.example.PropertiesPage, id = 3,
version = 5, ajax = 0] it could be that the component is inside a
repeater make your component return false in getStatelessHint()
the row index "properties:filterForm:dataTable:rows:5" keeps advancing
every time. There are only 2 rows in my test DataTable.
Could anyone comment? Maybe I am simply building the link for the row
incorrectly.

converter can not convert org.myproject.Something to a string

This leads to:

displayValue = converter.convertToString(objectValue,

The check does not seem correct. How can converter class be ever
assignable to an model object class? Or am I missing something?

In the api it says to use refreshingview instead of using listview when

what is better to use?

please mind that you shouldn't create anonymous model classes as they
keep the reference to the page/panel and you will fall into other memory
issues.

there is a single resources but it produces different content basing on

Model question
Assuming eventModel is loadable detachable model sould I implement some
marker interfaces in the following model?
private static class SystemWarningEventImagePathModel extends
AbstractReadOnlyModel {
private IModel eventModel;
public SystemWarningEventImagePathModel( IModel eventModel ) {
this.eventModel = eventModel;
}
@Override
public Object getObject() {
SystemWarningEvent event = (SystemWarningEvent)
eventModel.getObject();
return event.isReadFlag() ? "img/mobile/event_read.png" :
"img/mobile/event_new.png";
}
}
There are a number to take into account: IWrapModel, IChainingModel.
Please advise.

The model looks like this:
unitconfig -> thermometers
each thermometer is being wrapped with loadable detachable thermometer
model which holds its id
thermometer -> lowlevelsensor
lowlevelsensor -> actions
each action wrapped with loadable detachable action model
everything is based on property models apart from building refreshing
list elements which do not need parent model.
