Iterate over Pages in Pagemap
Hi all, how to iterate over latest version of all pages in pagemap? All my Pages have the ability to reload the navigation, but to accomplish this, I need to tell the page to reload the navigation. So my first idea was to iterate over latest version of all pages in pagemap and call the needed method on it. But Session#getPageMaps returns a list of IPageMap which doesn't offer an iterator. How can a accomplish this? Greets Chris
Force page reload/re-render
I have a link on a panel that is included in many pages. When the user clicks on the link, I change something in the user settings that will affect what gets displayed on the page. However, for that to work, I need to reload the page after the user clicked on the link as by default the other components that now need to be checked for conditional visibility don't re-render (why not?). setResponsePage() requires me to pass into the panel a target page and this becomes complex when you have a mix of statefull and stateless pages as targets (and it just doesn't feel right). I am sure there must be an easier way to just re-render a page? Any tips?

You can also use your logger implementation and then log in a format
that a log analysis tool can read. This however, is a very old style
approach compared to analytics in my opinion. The quality of the
analysis and ease of implementation with analytics is just so much
better.

Inheritance strips XML header
Hi all, It seems that Wicket 1.4.3 is stripping the XML header when using page inheritance for layout. My super page defines the layout and has a ?xml header at the top. If a sub page has content, when wicket renders it, the ?xml header will be excluded. Strangely, for subclasses with no content (no html file), the ?xml header is preserved. Am I doing something wrong? If not, I have a sample application that shows this issue and would be happy to file a bug. We're actually using 1.3.7, but if this will only be fixed on 1.4, that would be a great excuse to upgrade :) Thanks, Neil

It wouldn't matter because they're not "injecting" it into the

RE: Combination CompoundPropertyModel and ChoiceRenderer on DropDownChoice gives problems
I am a newb here, so I may be way off, but this works for me:
public final static ChoiceRenderer listRenderer = new
ChoiceRenderer("description", "id");
Expose description and id on your model's object.
And just add the listRenderer to the DDChoice (last param).
Seems a lot simpler than what you are doing.

Got it!
Here is the code i got into. Improvements and critics are welcome !
class MappedModel extends Model {

return (String) map.get(id);
}
}
// Localized choices
final MappedModel countryModel = new MappedModel(){

Re: serialization
sorry sorry i made a mistake in the populateItem
these is a nested listview
populateItem(ListItem item) {
final ValueObject valueObject = item.getModelObject();
add(new ListView("child", getOthers()) {
populateItem(ListItem item) {
Money price =
getPricingService().calculatePrice(valueObject,
item.getModelObject())
}
}
}
Looks like the problem has to do with me accessing the valueObject
variable from inside the nested ListView. any clean way around this?

Re: serialization
hrm, nothing interesting there.
can you post the code for the entire page/panel...
also the serialization checker should tell you the exact field that is
holding the reference to the object further in its message...

serialization
Hi. Wondering if someone can help me with a serialization problem I'm
having.
To start off, the domain model in this application does not use
serializable domain objects (the project is using db4o, which does not
play well with serialized objects).
I have a page with this code:
IModel valueObjectList = new
LoadableDetachableModel() {
protected void load() {
return getVOGenerator().generateVOs();
}
}
add(new ListView("vos", valueObjectList) {
...
});
I'm getting this error:
org.apache.wicket.util.io.SerializableChecker
$WicketNotSerializableException: Unable to serialize
class: ...ValueObject
How do I get around this?

Re: Autogenerating HTML files ...?
Hi Ashley, I actually wrote the list regarding a similar idea about a year ago. It seems like a handy thing for RAD and for newbies struggling with keeping simple CRUD pages in sync.

you dont need to put any code in your onsubmit...
class mysearchpage extends webpage {
private searchcriteria criteria=new searchcriteria();
public mysearchpage() {
add(new searchcriteriaform("form", new propertymodel(this,
"searchcriteria")));
^ form object connected to the criteria field of this page via a
property model
add(new listview("results", new propertymodel(this,
"searchresults")) {...});
^ listview that will display results retrieved from the
getSearchresults() method on this page
}
public list getSearchresults() {
// get whatever results based on the criteria field
}
}
so in short, form pushes your criteria into the criteria field,
listview uses the criteria field to build the resultset. yes, its that
simple :)

Re: Combination CompoundPropertyModel and ChoiceRenderer on DropDownChoice gives problems
Got it!
Here is the code i got into. Improvements and critics are welcome !
class MappedModel extends Model {

public String getDescription(Object id){
return (String) map.get(id);
}
}
// Localized choices
final MappedModel countryModel = new MappedModel(){
public Object getObject() {

return new ArrayList(super.map.keySet());
}
};
DropDownChoice ddcCountry= new
DropDownChoice("country",countryModel);
ddcCountry.setChoiceRenderer(new IChoiceRenderer() {
public Object getDisplayValue(Object object) {
return countryModel.getDescription(object);
}
public String getIdValue(Object object, int index) {

Re: Combination CompoundPropertyModel and ChoiceRenderer on DropDownChoice gives problems
Hi Ernesto, Sven,
Regarding the usage of localizeDisplayValues, I see that if I put simply "M"
or "F" it also works. Wonderful! Now I can define a general description for
"M" and "F", and provide specialized ones in case of need (thinking about
yes/no literals). But, could I someway define 'groups' of yes/no
descriptions (i.e. yes/no, positive/negative) and tell someway the component
to look for one or antoher having only the "Y", "N" literals? (maybe out of
scope on this question)
Why not use IChoiceRenderer?
>
I suppose you mean anonimously subclassing ChoiceRenderer and overriding
getDisplayValue in order to get the proper description... Something like
what Pedro proposed here maybe?
http://mail-archives.apache.org/mod_mbox/wicket-users/200911.mbox/%3c341aa5500911040801j3f2cb9e0tc1109314522d5...@mail.gmail.com%3e
That could be good, although maybe pulling out the description for each
choice could penalize performance...
Igor also proposed a solution to another problem that might come in handy in
http://www.mail-archive.com/wicket-u...@lists.sourceforge.net/msg26881.html
I'd like to do something like this:
// Localized choices
final Model countryModel = new Model(){
public Object getObject() {
return referenceData.getCountries(getLanguage());
}
};
DropDownChoice ddcCountry = new DropDownChoice("country",countryModel);
ddcCountry.setChoiceRenderer(new IChoiceRenderer() {
public Object getDisplayValue(Object object) {
return ((Map)countryModel.getObject()).get(object);
}
public String getIdValue(Object object, int index) {
return object.toString();
}
};
Only that countryModel's getObject should return a List instead of a Map
(and I'd like the model to be dynamic)
Thanks a lot!

best approach for a criteria and result page
Hi all,
I browsed a lot of wicket example and searched through many articles,
but never found this classical web application example : I would have on
the same page a form with some criteria, a search button and a result
list : I enter some data, hit search and get the results under my
criteria, just like google does.
No problem for me to define all these parts using wicket components, but
I don't know how to manage the workflow, and especially what code
should I put in my form's onSubmit method.
Here is a sample code :
public class TestPage extends WebPage {
public TestPage() {
super();
createComponents();
}
@SuppressWarnings("serial")
protected void createComponents() {
final WebMarkupContainer datacontainer = new
WebMarkupContainer("data");
Form searchForm = new
Form("searchForm",
new
CompoundPropertyModel(new SearchParameterBean())) {
@Override
protected void onSubmit() {
SearchParameterBean searchParam =
(SearchParameterBean) getModelObject();
// get contract list in a
LoadableDetachableModel, but can't give it to ListView
IModel>
contractListModel = new LoadableDetachableModel>()
{
@Override
protected List
load() {
List
contractList = manageContract.getContracts();
return contractList;
}
};
// This is working, but I must have an
inner class and final WebMarkupContainer datacontainer
// What to do if I want to create a
class ConsultForm extends Form
datacontainer.setVisible(true);
}
};
searchForm.add(new TextField("Id"));
add(searchForm);
datacontainer.setVersioned(false);
datacontainer.setVisible(false);
add(datacontainer);
// here I do not have access to my contractListModel
PageableListView listView = new
PageableListView("contracts", contractListModel, 10){
@Override
public void
populateItem(ListItem listItem) {
ResultParameter contract =
listItem.getModelObject();
Label name = new Label("Name",
contract.getName());
listItem.add(name);
}
};
datacontainer.add(listView);
}
The questions I have are :
- How to pass model between the onSubmit() message which defines it, and
the FormView which shows itin the page ?
- Do I have to define a setResponsePage() in my onSubmit() ? If I do so,
I must go to another page, and then I lost the user's choosen criteria
- What is the best practice to build such an application ?

Unnecessary method calls in IDataProvider?
Hey, I could have sworn that if a IDataProvider used in a DataView returns 0 as size, the iterator(int,int) method won't be called. But that assumption proved me wrong some minutes ago. Is there any specific reason why iterator gets called when the only possible result is an empty Iterator? Wouldn't it be more sensible to assume an empty iterator if size() returns 0 and leave out the method call? regards, - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org

Re: Combination CompoundPropertyModel and ChoiceRenderer on DropDownChoice gives problems
Hi Sven,
Absolutely awesome. So sweet how problems vanish away when you know the
right way to address them on Wicket: ).
But, what if I had a list of countries in the database (better example than
gender in this case), with its descriptions in it? Should I store a Country
entity in my bean, instead of simply and Id (taking into account this entity
possibly contains the descriptions and other unuseful stuff) ? Could I
manage someway, using the countryId's in the ddc's choiceList model, to look
for those descriptions in i.e. a memory-stored Map ?
Thanks a lot!

It is a consequence of disabling null values; you need to tell the dropdown to accept null values which is what "Choose Option" represents: theDropdownComponent.setNullValid(true); You will also want to override the display value property in the .properties file: theDropdownComponent.null_valid=Not set - Tor Iver - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org

Re: Combination CompoundPropertyModel and ChoiceRenderer on DropDownChoice gives problems
You want to select one value from a list of values, so obviously everything
has to have the same type.
These 'IdDescrBeans' smell like Struts, such constructs are not needed.
What's wrong with the following:
List genders = new ArrayList();
list.add("M");
list.add("F");
form.add(new DropDownChoice("gender", genders) {
protected boolean localizeDisplayValues() {
return true;
}
});
Creating an enum would be a nice alternative to strings though.
Put the following keys in you page's property file:
gender.M = male
gender.F = female
i18n for free.

Your Page (HomePage) contains a reference to your SpeedService EJB. Since that one is not serializable, your page cannot be serialized. A possible solution is to inject your ejb (by using for example @SpringBean). This makes serializable proxies, so your page can be serialized... 2009/11/9 zabian > Hi there, > I am working on the project using Wicket and EJB3.0 on Glassfish AS. > I've got such case: > There is a page with some test, using Sateful bean.

Autogenerating HTML files ...?
Dear All, I have seen a feature in Wicket Bench (I think it is) that can automatically generate the Web component object construction hierarchy for a given Web form with Wicket ids. It's a neat feature. However, I am wondering if it would be possible to do the reverse. Could Wicket classes be extended to automatically generate the HTML file (based on the Wicket object hierarchy) if the HTML file doesn't already exist? Obviously, it couldn't generate the non-dynamic HTML aspects of a Web page, but at least it could provide a skeleton page? This could be configured to overwrite (or not) existing files each time the code changed. Perhaps it could be configured to include (for debugging purposes) some Wicket information for each item in the page (almost like a RAD solution but the intention is not for RAD). Perhaps it could even use a form of the "generation gap pattern" by putting each dynamic chunk into a separate HTML file and then #include them into a main HTML file which it doesn't get overwritten. Though I'm not sure how this would exactly work ... I've seen Wicket RAD and Wicket Web Beans but these are not what I am thinking about. Eventually, I would want a graphics / Web designer to complete the page around the skeleton dynamic HTML parts (that perhaps Wicket has autogenerated). I know this would never be the full solution but it may allow one to concentrate just on the Java code and not even have to worry about the HTML to start with. I think it could be an interesting approach. Is this possible? Has this already been done? Any comments appreciate.

Hello all, Is it possible to automatically encode PageParameters? When I put a String like "bien-être" in a parameter, and redirect to a page using that parameter, I get an illegal url request. (only 0-9, a-z, A-Z and some characters are legal). Is it possible to encode it automatically, to: "bien-%C3%AAtre"?

Re: Combination CompoundPropertyModel and ChoiceRenderer on DropDownChoice gives problems
Hi Ann,
I've also encountered this problem, but with RadioChoice instead of
DropDownChoice.
This is the thread I started about it:
http://mail-archives.apache.org/mod_mbox/wicket-users/200911.mbox/browser
After all this thread, I still don't know what should I do to model, for
instance, a gender radioChoice which would be backed by a String property
("M" of "F"), providing a list of choices (multilingual) with IdDescrBeans
like you propose.
Should I change my bean's 'String gender' property to 'IdDescrBean gender' ?
Why should I store description's information on my model entity ?
Although I agree with having same object's on choices and model when it's
about more complex data...
Possible solutions I've thought of so far:
- Ideally, do not use different object types in compundpropertymodel's
bean and choice List. Use same object type instead.
- When using RadioChoice, it works if you substitute it with a RadioGroup
and Radio's, using the 'id' property as the Radio's model and the
'description' property as the label's model. However, when it's about
DropDownChoice, I'm clueless about it at the moment (already having problems
with them).
- Provide a list of choices in which each element is an Id, and then
provide a ChoiceRenderer display expression such that gets the proper
description (I don't like that at all).
- Modify IdDescrBean so that it returns the 'id' property in its
'toString' method, and, assuming the compundpropertymodel's bean related
property is String, provide an implementation for some useless method
('trim' for example), so that it returns the desctiption. Then, in the
ChoiceRenderer, you can set the displayExpression to 'trim()', which will
ensure that when the component model's object is a String, this error will
not happen (also, it will return the trimmed id as description, but that
will have no effect). But there is more to it, in order to achieve
AbstractSingleSelectChoice's getModelValue() to identify the selected choice
element, it calls 'indexOf' on the Choice List, using the
compundpropertymodel's bean related property value. That is, it searches in
a List of IdDescrBean a String. Problem is 'indexOf' invokes
'searchedElement.equals(choices[i])', which will never return true. I got it
to work overriding 'getModelObject' and doing this search with the opposite
comparation (choices[i].equals(searchedElement), and providing a suitable
implementation of 'equals' in the IdDescrBean class... But that's extremely
hacky and ugly, and... it would not work for ListMultipleChoice, as
getModelValue is final...
