Re: [Wicket-user] Standalong Radio component ?

[Ingram Chen]

Ok, I try nested with list but found a problem while SingleRadioChoice try to find parent

//original code:
private RadioChoiceGroup findGroup() {
        MarkupContainer parent = getParent();
        while (parent != null) {
            if (parent instanceof RadioChoiceGroup) {
                return (RadioChoiceGroup) parent;
            }
        }
       //..... omit
}

this make findGroup() run infinitely.

I try to fix this by:

private RadioChoiceGroup findGroup() {
        MarkupContainer parent = getParent();
        while (parent != null) {
            if (parent instanceof RadioChoiceGroup) {
                return (RadioChoiceGroup) parent;
            } else {
                parent = parent.getParent();
            }
        }
       // omit....
 }

and now work !

the singleradiochoice is not tied *directly* to the group. Its requirement is that the group component be somewhere above in the hierrachy. so per your example:

 

RadioChoiceGroup group=new RadioChoiceGroup(....);

group.add(list);

...

Thank quick response ! This almost fit my requirement. but SingleRadioChoice seems tight to RadioChoiceGroup. My form is dynamic constructed from database, so I need to use ListView to build, like:

ListView list = new ListView("checks", listOfData) {
     @Override
       protected void populateItem(ListItem item) {
            item.add(new SingleRadioChoice("choice", new PropertyModel(myModel,"selected"));

            Data data = "" item.getModelObject() ;
            item.add(new TextField("input", new PropertyModel(data, "input"));
       }
};

Any Idea ?

Yes, wicket lacks one of these. Just threw one together, let me know if it works for you or if you find any bugs. Something like this is too small for a wicket-stuff project, any ideas what i should do with it?

 

Basically it works like this.

 

Person p=new Person(); /// this is the model

 

RadioChoiceGroup group=new RadioChoiceGroup("group", new PropertyModel(p, "name"));

 

g.add(new SingleRadioChoice("c1", new Model("bob"));

 

g.add(new SingleRadioChoice("c2", new Model("dean"));

 

----

 

<span wicket:id="group">

 

    <input type="radio" wicket:id="c1">choose bob</input><br/>

 

    <input type="radio" wicket:id="c1">choose dean</input><br/>

 

</span>

 

the single choice components connect to the group by searching up the component hierarchy for the first group.

I know there is a RadioChoice component and it works great.... , but IChoiceRenderer
seems not enough when I need to do like:

    <p>Choose your anwer:</p>
    <input type="radio" >Answer 1 </input><br/>
    <input type="radio" >Answer 2 </input><br/>
    <input type="radio" >Other: <input type="text" name="others" /> </input><br/>

Is there a standalone radio componet like CheckBox ?
Or another way to solve above problem ?

Thanks
