how to call a javascript function?
Hi, I have a form in a page, after user fill some data in and press 'Save' I
want to call/or not to call a javascript function, in my code I was try to
do like:
Form form = new Form(form, new CompoundPropertyModel(this)){
protected void onSubmit(){
activity.setReference(reference);
(new ActivityManager()).storeActivity(activity);
//setResponsePage(new ActivityTypesMenu());
}};
TextField activityDateTF = new TextField(activityDate, new
PropertyModel(this,reference));
activityDateTF.setRequired(true);
form.add(activityDateTF);
Button saveBtn = new Button(save);
saveBtn.add(
new SimpleAttributeModifier(
onclick, something();));
form.add(saveBtn);
add(form);
However I don't think I am doing it right, one thing that javascript
function not be called so I am asking help again here...
Many thanks again.

working with JSP problem, thanks!
Hi, my wicket pages need to be worked with some other jsp pages, and for some reason I need two startup place so in xml conf files I got: servlet servlet-nameAdminPagesApplication/servlet-name servlet-classorg.apache.wicket.protocol.http.WicketServlet/servlet-class init-param param-nameapplicationClassName/param-name param-valueapto.umbrella.wicketInterface.AdminPagesApplication/param-value /init-param /servlet servlet-mapping servlet-nameAdminPagesApplication/servlet-name url-pattern/Admin/*/url-pattern /servlet-mapping so I was try to put more something like: servlet servlet-nameAdminPagesApplication/servlet-name servlet-classorg.apache.wicket.protocol.http.WicketServlet/servlet-class init-param param-nameapplicationClassName/param-name param-valueapto.umbrella.wicketInterface.AdminPagesApplication/param-value param-valueapto.umbrella.wicketInterface.AdminPagesApplication2/param-value /init-param /servlet servlet-mapping servlet-nameAdminPagesApplication/servlet-name url-pattern/Admin/*/url-pattern servlet-nameAdminPagesApplication2/servlet-name url-pattern/Admin2/*/url-pattern /servlet-mapping But then it won't work, I think it probably something really simple to change, sorry to bother again for those newbie questions!

Re: required field in a form, help :)
Thansk very much, I finally use a Link instead, much better.

Read the JavaDoc of Button:
One other option you should know of is the 'defaultFormProcessing'
property of Button components.
When you set this to false (default is true), all validation and
formupdating is bypassed and the
onSubmit method of that button is called directly, and the onSubmit
method of the parent form is
not called. A common use for this is to create a cancel button.
Or search the archives:

Hi, I have some inputs in a form, some are required field, they work fine
when I press 'submit' button, however, I also include a cancel button, in
which onclick event my code is like:
add(new Button(cancel){

setResponsePage(new ActivityTypeList());
}
});
But I think it's probably button 'cancel' has attribute type='submit' in
html page, but I can't put reset, so I don't know what to do to avoid the
validation when user press 'cancel' ?
Many thanks,

problem of updating a panel
Hi chaps, I am using a panel in a page, and I actually using a DataView with paging enable in the panel for show some data, I pass the datasource from the webpage to that panel, something Like final Panel p = new BoxListPanel(boxListView,boxList);, everything is fine, but now the data getting too much so I decide to use lazy_loading like the repeater in wicket example: http://www.wicketstuff.org/wicket13/repeater/ so I only get the data I actully need for the page, and it was working fine, however, in my page user can customize the data source, so I need to update the panel after user click on some ajaxLink, I can do this in previous way but after I use the IDataProvider like the example in repeater, I can't update the panel, in my page I define the panel like: final Panel p = new myPanel(boxListView,new BoxDataProvider(selectContion)); so I actully then pass a selectContion for the panel instead the actualy data source, but it only working at the first load, if I change the selectContion, the data is not changing, but if I pass in the actully data then it's fine. I hope this make sense... or is there any other good lazy-data loading examples? -- View this message in context: http://www.nabble.com/problem-of-updating-a-panel-tf4758150.html#a13606873 Sent from the Wicket - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

question about 'isInstantiationAuthorized' method, thanks!
Hi, I am using isInstantiationAuthorized method in a application class for some simply security check, which is working fine, if the user doesn't have the right to access a page, page display: Access Denied You do not have access to the page you requested. Return to home page However, I can't change the url for 'Return to home page' link, as the homepage is a jsp page but 'Return to home page' link just send me to the default wicket homepage which specifed in xml file right?

how to change format in DateTimeField?
there is a good example about use DateTextfield in : http://www.wicketstuff.org/wicket13/dates/?wicket:bookmarkablePage=sources%3Aorg.apache.wicket.examples.dates.DatesPage however, I want to add the time field as well, so I found DateTimeField which is working, however i don't know how to change the format of the date it displayed, in DateTextfield I believe I can do that with using its constructor: new DateTextField(dateTextField, new PropertyModel(this,date), new StyleDateConverter(S-, true)), but DateTimeField only has a constructor: new DateTimeField(dateTimeFromTextField, new PropertyModel(this, date)) so I don't know how to change its format, also I want to prevent user to type in invalid date in the text field as well, becuase if user type some letters in the textfield next to the date picker then the date picker won't start properly as well. I might asking dump question becuase I am too new to wicket (I use asp.net before).

DropDownChoice - how to get the current selected value and I can't use OnSelected event as well :(
Hi, I am quite new to wicket and got 2 questions about DropDownChoice don't
know how to solve even after some googling as well from this forum so need
some helps again:
1. I want to get the current selected item's value from DropDownChoice, I
was looking for something like
DropDownChoiceObject.selectedValueOrID() - something equitvalent, I saw the
example from wicket website, it's using:
DropDownChoice ddc =
new DropDownChoice(name,
new PropertyModel(employee, managedBy),
new LoadableDetachableModel() {
...
}
);
so do I have to pass in a PropertyModel to achieve what I want? mine is:
final MapString, String choiceMap = new HashMapString,
String();
final ListString jpNameString = new ArrayList();
for (JobProfile j : jobProfiles){
choiceMap.put(String.valueOf(j.getId()), j.getName());
jpNameString.add(String.valueOf(j.getId()));
}
IChoiceRenderer renderer = new ChoiceRenderer() {
public Object getDisplayValue(Object object) {
return choiceMap.get(object);}
public String getIdValue(Object object, int index) {
return object.toString();
}
};
final DropDownChoice ddc = new DropDownChoice(
filterByJobProfileName, jpNameString, renderer)
2. my second question is how to use event OnSelectionChange, I saw two
events from the API, one is final so I can't overide, one is pretected:
final void onSelectionChanged()
protected void onSelectionChanged(java.lang.Object newSelection)
I can't use either like:
final DropDownChoice ddc = new DropDownChoice( filterByJobProfileName,
jpNameString, renderer){
void onSeclectionChanged(){
//I want to do somethign here if this is working :(
}
};
Many thanks for your help!

hi questions about Wizard again, thanks!
Hi, sorry to ask questions again
I have a WizardPage, got 2 questions don't really know how to solve,
My WizardPage is like
public class AddDeliveryWizardPage extends AbstractExamplePage{
public AddDeliveryWizardPage(){
super();
WizardModel model = new WizardModel();
int numberOfBoxes = 0;
ListBox boxesList = new ArrayListBox();
//variable 'numberOfBoxes' will be set in this
step
model.add(new SetNumberOfBoxesWizardStep());
//set box entity objects according to variable
'numberOfBoxes' set from last step
model.add(new SetBoxEntityWizardStep(int numberOfBoxes));
Wizard wizard = new Wizard(wizard, model)
this.add(wizard);
}
}
question 1: as model step is added at compile time, so I don't know how to
get the value of variable 'numberOfBoxes' after it got set from the 1st
step, in the 2nd step 'numberOfBoxes''s value is default value 0.
question 2: in the 2nd step I probably need user to input multiple box
object's details, for a single model, I can use somthign like setModel(new
CompoundPropertyModel(box)), but what about for multiple objects? is it
something like setModel(new CompoundPropertyModel(boxeslist)) - boxeslist
is a arraylist of box objects.
Many thanks for your guys help, this is the best forum I can find for wicket
:)

You should make numberOfBoxes variable accessible in both the steps. One
way to do it:
public class AddDeliveryWizardPage extends AbstractExamplePage{
private int numberOfBoxes;
private final ListBox boxesList = new ArrayListBox();
public AddDeliveryWizardPage(){
super();
IModel boxesAmountModel = new PropertyModel(this,
numberOfBoxes);
WizardModel model = new WizardModel();
//variable 'numberOfBoxes' will be set in this step
model.add(new SetNumberOfBoxesWizardStep(boxesAmountModel) {
public void applyState() {
for (int i = 0; i numberOfBoxes; i++)
boxesList.add(new Box());
}
});
//set box entity objects according to variable 'numberOfBoxes'
set from
last step
model.add(new SetBoxEntityWizardStep(boxesAmountModel,
boxesList));
Wizard wizard = new Wizard(wizard, model)
this.add(wizard);
}
}
question 2: in the 2nd step I probably need user to input multiple box
object's details, for a single model, I can use somthign like
setModel(new
CompoundPropertyModel(box)), but what about for multiple objects? is it
something like setModel(new CompoundPropertyModel(boxeslist)) -
boxeslist
is a arraylist of box objects.
Notice that I added a boxesList parameter for the second step in the
code above. So then in the SexBoxEntityWizardStep you could use some
repeater to generate html inputs for every box. For example here is a
ListView example:
add(new ListView(boxes, boxesList) {
protected void populateItem(final ListItem item) {
item.add(new TextField(name, new
PropertyModel(item.getModelObject(), name));
}
});
Many thanks for your guys help, this is the best forum I can find for
wicket

Hi experts,
I want to implement a wizard, user need to input some data, I can do it
with
a single page using form, but I don't know how to do it in wizard, I put
a
couple of input textfield etc. then I get a error:
java.lang.IllegalStateException: Attempt to set model object on null
model
of component: wizard:form:view:expectedNumberOfBoxes
Note: expectedNumberOfBoxes is the first textfield I declared in the java
class, after googling a few hours(not too much information) I think I
need
to setup a 'model'? but I probably need more details how... my code is
like:
public class DeliveryDetails extends WizardStep {
public DeliveryDetails(Delivery delivery, String title, String
content){
super(title, content);
RequiredTextField expectedNumberOfBoxesTextField = new
RequiredTextField(expectedNumberOfBoxes, Integer.class);
add(expectedNumberOfBoxesTextField);
RequiredTextField receivedNumberOfBoxesTextField = new
RequiredTextField(receivedNumberOfBoxes, Integer.class);
add(receivedNumberOfBoxesTextField);
}
Yep, you need to work with models. For instance:
RequiredTextField receivedNumberOfBoxesTextField = new
RequiredTextField(receivedNumberOfBoxes, Integer.class, new
PropertyModel(delivery, receivedNumberOfBoxes));
add(receivedNumberOfBoxesTextField);
or:
setModel(new CompoundPropertyModel(delivery));
RequiredTextField receivedNumberOfBoxesTextField = new
RequiredTextField(receivedNumberOfBoxes, Integer.class);
add(receivedNumberOfBoxesTextField);
