Re: [Wicket-user] check box questions how to I associate an object with a boolean seletion from a checkbox component

ok so i'm trying to implement my own model but i have little idea what i am
suppose to be trying to do here. can someone please give a brief overview as
to what the getObject, and setObject expects and does please. I am really
lost and need some help with this. also how does the model intereact with
the componenet..what do they tell each other.?

Re: [Wicket-user] check box questions how to I associate an object with a boolean seletion from a checkbox component


this part of the concept i understand...what i don't get is a little
deeper...from your example i am accessing a property in input. however, I
don't have such a property in my object. I some how have to figure out if
that mode is selected. basically, i want to implement imodel as show in a
example on the forum to put my object in a collection if it is selected. In
the example ivan implements imodel. and set  that model as the model that
the checkbox works with.

 Wicket models are a way to locate values.
 
 Let's take a look at wicket.examples.compref.CheckBoxPage. That page
 has a nested static class called Input, with a property bool:
 
   private static class Input implements Serializable
   {
   public Boolean bool = Boolean.TRUE;
   }
 
 Then, in CheckBoxPage's constructor we do (simplified):
 
   final Input input = new Input();
   setModel(new CompoundPropertyModel(input));
   Form form = new Form(form);
   form.add(new CheckBox(bool));
 
 CompoundPropertyModel might be a bit distracting, so let's rewrite
 this to use a normal model:
 
   final Input input = new Input();
   Form form = new Form(form);
   form.add(new CheckBox(bool, PropertyModel(input, bool)));
 
 another way to rewrite the model:
 
   form.add(new CheckBox(bool, new Model(input)
   {
   public Object getObject()
   {
   return ((Input)super.getObject()).bool;
   }
 
   public void setObject(Object object)
   {
   ((Input)super.getObject()).bool = (Boolean)object;
   }
   }));
 
 and yet another to rewrite the model is:
 
   form.add(new CheckBox(bool, new IModel()
   {
   public Object getObject()
   {
   return input.bool;
   }
   
   public void setObject(Object object)
   {
   input.bool = (Boolean)object;
   }
   
   public void detach()
   {
   }
   }));
 
 and *yet* another way is:
 
   form.add(new CheckBox(bool, new AbstractCheckBoxModel()
   {
   @Override
   public boolean isSelected()
   {
   return input.bool;
   }
 
   @Override
   public void select()
   {
   input.bool = true;
   }
 
   @Override
   public void unselect()
   {
   input.bool = false;
   }
   }));
 
 If you compare these examples, the constant factor is that we're after
 the bool property of the Input instance. It is important that you
 understand that the typical thing for Wicket models to do is to pass
 and get values from other objects, typically your domain objects or
 'form beans' (that's the name which other frameworks often use). Here,
 the Input instance is that object, and any of the above combinations
 just provides the facility for components to work on that object in a
 generic fashion.
 
 So... the CheckBox component calls getObject on it's model to
 determine whether it should render itself as checked or not. It calls
 setObject on the model when it receives input. The typical case for
 that is when it is part of a form. The form calls updateModel on all
 nested components, and the components then call setObject with the
 received  (and converted) input.
 
 Now, to get back to your original question. We could rewrite the above
 example to work on a list of checkboxes/ input objects like this:
 
   ListInput inputs = new ArrayListInput(Arrays.asList(new Input[] {
 new Input(),
   new Input(), new Input() }));
   ListView l = new ListView(list, inputs)
   {
   @Override
   protected void populateItem(ListItem item)
   {
   // item.getModel().getObject() would give the Input 
 instance for
   // this particular list element
   item.add(new CheckBox(bool, new 
 PropertyModel(item.getModel(),
 bool)));
   }
   };
   form.add(l);
   System.err.println(selection for the second input:  +
 inputs.get(1).bool);
 
 As you can see, the idea stays the same; in both cases we're after the
 bool property of instances of Input.
 
 I'd say, let this sink in a bit, and try to play with this code
 yourself, so that you understand better how it works.
 
 Hope this helps,
 
 Eelco

I read the thread again and still don't quite understand. I thought i
understod models but maybe i don't i am going to read the wiki on that now.
but in between this is what i think all the tread is saying tell me if i'm
wrong or not.

its saying that you create a custom model that takes as an argument in the
constructor the object/model that you want to tie to a check box. this model
is used as the model that we pass to our check box component. the setObject
method gets called at the push of the submit button and sets that

Re: [Wicket-user] form processing - getting dropdown selection back to onSubmit method.

2007-03-20 Thread GS-ikiini


don't understand: look up a localized string with the key nullValid
(rather than  
null) to represent the null option. - can you elaborate a bit please.
need to know what a localised string is and what is its key. thank you

 DropDownChoice.setNullValid(true)
 
 And remember that for a null valid drop down choice, Wicket will  
 look up a localized string with the key nullValid (rather than  
 null) to represent the null option.
 
 Also see the JavaDocs for DropDownChoice and it's superclasses, plus  
 this wiki page: http://cwiki.apache.org/WICKET/dropdownchoice- 
 examples.html

 the model for each dropdown is specified as a propertymodel where  
 this
 refers to the page and the string refers to the property on that  
 page.

 so the selected user object will go into the user page property,  
 and the
 selected logtype will go into the page's logtype property just  
 like the
 property models specify.

 then your dataprovider picks up those two properties and uses them to
 filter
 the result just like the code shows.

 the models are just glue between formcomponent and properties on  
 some java
 bean - which in this case happens to be the page.

I see..I am still thinking in old java style...let me try again...

i have my dataprovider class/model. my page class and 2 beans. in my
dataprovider class.model, the 2 beans are properties. that i need to set via
drop down choice. so i set them as specified here. what i don't understand
is where does the user object that we set come from? if i select string x
from the drop down how do we get the object that sting x in the drop down

[Wicket-user] form processing - getting dropdown selection back to onSubmit method.


hey all,

I am attempting to do some form processing for a filter that i am building.
I user 4 dropDownChoice in a form with a submit button. I want to overide
the onSubmit method, which i did. however when i try to get the values
selected from the drop down in the method for prodessing, they come back
empty. I am using pro wicket as a reference. i wrote simple helper methods
as illustrated in the book but they don't seem to work:


...
desc = new FilterChoice(description,ldp,processTypeDropDownList,logs);
...
 
protected String getDescriptionSelection(){
return desc.getModelObjectAsString();
  }

...
@overide
onSubmit(){
if(MyClass.this.getDescriptionSelection() .equals(something)){
   do something...
}

thing is...I insert some log.debugs in there to see what was being returned
and nothing came back. How can i get the selection back to my onSubmit
method i guess is my question. Thank you

Re: [Wicket-user] form processing - getting dropdown selection back to onSubmit method.

yes i have but i am not quite sure how to apply it to what i am doing. It
calls for a model on which the current selecting is designated thing is in
my selection list i have a strings. but in the model that need setting i
have only mostly bean properties. what i want to do is as the user makes a
selection, i want to take that selection and look up the appropriate bean.
then pass that bean to the model which does something with it. any
suggestions on how to accomplish this?

Re: [Wicket-user] form processing - getting dropdown selection back to onSubmit method.

i seei have a fair understaning of models this is what i am doing: I have
a dataprovider that services a dataview. this data provider is the the model
that i ultimately need to update. however the properties within this are
beans i need to set them using the selection from the dropdown. so fo
instancemy dataprovider has a property that is a saya user. this user
itself has a property called name. which is a string. now in my webpage
class i have a dropdown with a list of names. what i need to do is select a
name and get the appropriate bean to pass it to the dataprovider so that it
can do its thing and return its results to the dataview. how would i go
about this?

Re: [Wicket-user] form processing - getting dropdown selection back to onSubmit method.

I have an implementaion of IDataProvider. that has setters in it and
originally i used it like a model. however the properties have now been
changed to beans. can i still use what you say below? does that populateItem
go into my implementaion of dataView?

in other words,

Imodel myModelwhichImplementsIDataProvider = new
PropertyModel(item.getModel(),user)//user is the name of the user property
in myModelwhichImplementsIDataProvider.

igor.vaynberg wrote:

first of all the dataprovider is a readonly interface, it has no set

that said what you want is simple:

populateitem(item item) {
final imodel namemodel=new propertymodel(item.getmodel(), name);
add(new dropdownchoice(names,namemodel,nameslist));
}

Re: [Wicket-user] form processing - getting dropdown selection back to onSubmit method.


 The popilateItem as i know it is used within the dataview. That part i
understand. let me re-explain myself.

on my webpage class, i have a dataview component. i also have a dropdownview
component . they are both children of a form component. i have a beans user,
log and logtype. (I am using wicket along with spring.). now in my webpage
i have a drop down class whic implements dropdownchoice. the list for the
drop down is generated earlier in the webpage class. i have a drop down for
the user. and a drop down for the log type. I want to get the user selection
for these two, tie it back to the appropriate bean then set those beans in
the implementation of the dataprovider then use the implementation of the
data provider as the model for the dataview. My problem lies is getting the
user selection from the drop down. I can't seem get it without having a
model to tie it to.

Re: [Wicket-user] spring bean injection and interfaces(IDataProvider)


how do i do this? can you please give me an example. below is what i did.
maybe you can point out what i need to do.

in the myProjectApplication{

public myProjectApplication() {
super();
  }

  @Override
  protected void init() {
// Spring injector
addComponentInstantiationListener(new SpringComponentInjector(this));
}
...

public class thePage extends WebPage{

@SpringBean(name = adminService)
  private AdminService adminService;
  private dataProvider dp;
public thePage(){

  String test = adminService.print();
  log.debug(Checking adminService: + test);
  dp = new DataPrivicer();
 }

...

now this is the problem..

public class DataProvider implements IDataProvider {

  @SpringBean(name = adminService)
  private AdminService DPadminService;
  

public DataProvider(){
String test = BLDPadminService.print();
log.debug(Checking adminService in the BLDP constructor: + test);
   }

..

the above returns a nullpointer exception. by the way, the above is used is
the pageclass.

please please tell me how i would use your method to fix this
