Re: Setting a relevant value for radio buttons without using RadioChoice
Thanks thats taught me something about radio groups that I wasn't able to
find in the books I have. Your example was very helpful.

Hi ArchieC,
The way RadioGroup works is that it renders to a hidden field and stores
the selected value of the selected Radio.
i.e. the rendered markup is not that relevant and the model object for
the selected radio will be placed into the model for the RadioGroup when
the form submits.
This is how I've used it:
RadioGroup group = new RadioGroup (group, new Model());
Radio apple = new Radio (apple, new Model (Fruit.APPLE));
Radio orange = new Radio (orange, new Model (Fruit.ORANGE));
group.setModelObject (Fruit.APPLE);
Here by default the first radio is selected.
When the form submits group.getModelObject() will return either
Fruit.APPLE or Fruit.ORANGE depending on the selected radio button
In your case the RadioGroup will have as its model Object the value of
the selected radio.getModelObject() so whatever the value of user is
coming from the PropertyModel() for the selected option.

Mike
RadioGroup group=new RadioGroup(group, new Model(id));
final ArrayList SelectOptionLevel selectOptionLevel =
getDdcChoices();
ListView persons=new ListView(persons, selectOptionLevel) {
/**

private static final long serialVersionUID = 1L;
protected void populateItem(ListItem item) {
SelectOptionLevel option = (SelectOptionLevel)
item.getModelObject();
//Exampe of Icon setting
item.add(new Label(levelImage, img
src='images/icons/icon1.gif'/).setEscapeModelStrings(false));
Radio radio = new Radio(
radio,
new PropertyModel(modelObject, user)
~~ Need to set the value of the radio to
my option.getValue() value.
);
item.add(radio);
item.add(new Label(name, option.getLabel()));
}
};
group.add(persons);
add(group);
Apart from not getting a value it all looks great just as I want.

Re: Setting a relevant value for radio buttons without using RadioChoice
Hmmm but why not just do it with a LDM? Im a bit puzzled, heres what I do:
RadioGroupEventType eventTypeRadioGroup = new RadioGroupEventType(
eventType);
eventTypeRadioGroup.setLabel(new ModelString(Type of
Event));
ListViewEventType eventTypesListView = new
ListViewEventType(
eventTypeRadios, Arrays.asList(EventType.values())) {
@Override
protected void populateItem(ListItemEventType item) {
item
.add(new RadioEventType(eventType, item
.getModel()));
item.add(new Label(label, new ModelString(item
.getModel().getObject().getName(;
item.add(new IconPanel(icons, item.getModelObject()
.getIconTypes()));
}
};
eventTypesListView.setReuseItems(true);
eventTypeRadioGroup.setRequired(true);
eventTypeRadioGroup.add(eventTypesListView);
add(eventTypeRadioGroup);
Hmm this might be a bad example as I don't use LDM ../ But the important
line are :
item.add(new RadioEventType(eventType, item.getModel()));
if you select a certain radio within a group the group will return the
radios objectmodel...

Hi Nino,
I believe that this is not what Archie asked about, he wanted to
place database id's in the value of the radios.. Dont know why he
wanted to though... I might have gotten it wrongly though..
You're right that he wanted to use the database id but from his
example there didn't seem to be any client side use of this
information. My thinking is that he renders a list of users denoted
by radio buttons and he want to encode the user id (for a LDM?) as the
value for use on the form submission processing (i.e. which user to
work with in the next stage).
Because there is no requirement for the user id on the client side
there is no reason to care about the value used by the Radio as it is
just used internally by RadioGroup to know which model object to use
when the form is submitted.
There is no need for an IChoiceRenderer in this case because the Model
object of each Radio is never rendered.
He should just encode what he needs in the Model of each Radio and
expect to find it in the model of the RadioGroup when the form submits.
In his example:
RadioGroup group=new RadioGroup(group, new Model(id));
final ArrayList SelectOptionLevel selectOptionLevel =
getDdcChoices();
ListView persons=new ListView(persons, selectOptionLevel) {
/**
* */
private static final long serialVersionUID = 1L;
protected void populateItem(ListItem item) {
SelectOptionLevel option = (SelectOptionLevel)
item.getModelObject();
//Exampe of Icon setting
item.add(new Label(levelImage, img
src='images/icons/icon1.gif'/).setEscapeModelStrings(false));
Radio radio = new Radio(
radio, new
Model(option.getValue()) // -- this is how to wire the Radio Model
item.add(radio);
item.add(new Label(name, option.getLabel()));
}
};
group.add(persons);
add(group);
This will make group.getModelObject() return the option.getValue()
(i.e the user id) for the selected view item and allow him to proceed
to the next step.

Mike

Setting a relevant value for radio buttons without using RadioChoice
Hi All
Im fairly new to wicket and Im going insane with an issue Im having. Ive
been doing a trawl of many forums, Wicket in action, Pro wicket, nabble,
asking questions of friendly people and trying every option I can think of
to work this out for myself using RadioChoice, RadioGroup and odd
combinations of both.
I promise Ive been trying to avoid asking this question on the forum cause
Im expecting someone to call me an idiot. So here is my question.
RadioChoice has the ability to set a value thats not the standard radio7
type value. As far as we (myself and the java developer I am working with)
can see, we cannot seem to do the same for a Radio component in a
RadioGroup. Are we barking up the wrong tree completely or is there a way to
set a value to an ID from our database (for example).
EG.
Instead of input type=radio name=group value=radio7 /
I get input type=radio name=group value=353 / (353 being the
user_id of one of the accounts, set in option.getValue() - please see code
snippet below).
Here is the reason we cant just use a RadioChoice. The list we are making
contains about 1000 User account names, each with a user level denoted by an
icon next to each name and radio button. RadioChoice doesnt give the option
of doing different icons (Label with IMG html in it for Icons) for each name
as setPrefix just sets one for the whole list. The list is basically acting
like a drop down box so that I can select one of the accounts for editing on
the next page.
Im really stumped by this as I cant seem to find any reference to setting
this value on a Radio component and I cant believe the creators of Wicket
would make a pointless component.
Here is my code if that helps
RadioGroup group=new RadioGroup(group, new Model(id));
final ArrayList SelectOptionLevel selectOptionLevel =
getDdcChoices();
ListView persons=new ListView(persons, selectOptionLevel) {
/**
*
*/
private static final long serialVersionUID = 1L;
protected void populateItem(ListItem item) {
SelectOptionLevel option = (SelectOptionLevel)
item.getModelObject();
//Exampe of Icon setting
item.add(new Label(levelImage, img
src='images/icons/icon1.gif'/).setEscapeModelStrings(false));
Radio radio = new Radio(
radio,
new PropertyModel(modelObject, user)
~~ Need to set the value of the radio to
my option.getValue() value.
);
item.add(radio);
item.add(new Label(name, option.getLabel()));
}
};
group.add(persons);
add(group);

Re: Setting a relevant value for radio buttons without using RadioChoice
Erm from looking at the docs, Both Radio and RadioGroup only have an Id and an IModel in their constructor unlike RadioChoice which has a choice renderer. -- View this message in context: http://www.nabble.com/Setting-a-relevant-value-for-radio-buttons-without-using-RadioChoice-tp20978297p20978462.html Sent from the Wicket - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
Re: Setting a relevant value for radio buttons without using RadioChoice
Hmm it does'nt.. And you cant even overrride getValue() on radio since
it's final... :( Come it, I posted something about the fact that radio
uses autoIndex once regarding jmeter..
But you can override onComponentTag, I guess I'd probably roll my own
and rip most from Radio, but let it take the optional choicerenderer..

Re: Setting a relevant value for radio buttons without using RadioChoice
Hi ArchieC,
The way RadioGroup works is that it renders to a hidden field and stores
the selected value of the selected Radio.
i.e. the rendered markup is not that relevant and the model object for
the selected radio will be placed into the model for the RadioGroup when
the form submits.
This is how I've used it:
RadioGroup group = new RadioGroup (group, new Model());
Radio apple = new Radio (apple, new Model (Fruit.APPLE));
Radio orange = new Radio (orange, new Model (Fruit.ORANGE));
group.setModelObject (Fruit.APPLE);
Here by default the first radio is selected.
When the form submits group.getModelObject() will return either
Fruit.APPLE or Fruit.ORANGE depending on the selected radio button
In your case the RadioGroup will have as its model Object the value of
the selected radio.getModelObject() so whatever the value of user is
coming from the PropertyModel() for the selected option.

Mike

You're right that he wanted to use the database id but from his example

Because there is no requirement for the user id on the client side there

form is submitted.
There is no need for an IChoiceRenderer in this case because the Model
object of each Radio is never rendered.
He should just encode what he needs in the Model of each Radio and
expect to find it in the model of the RadioGroup when the form submits.
In his example:

}
};

This will make group.getModelObject() return the option.getValue() (i.e
the user id) for the selected view item and allow him to proceed to the
next step.
