formComponentPanel with content generated by RepeatingView
hi,
Im trying to implement a simple form component that accepts List of Strings
*public class AccountsPanel extends FormComponentPanel<List<String>>
{
** **public AccountsPanel(String id, ArrayList<String> accounts) {
** ** **super(id, new Model(accounts));
buildComponents();
}
}
*and I am using RepeatingView to create as many TextField as many Strings
are in the List, and this is fine but how then convert each edited value of
the TextField back to List of Strings???
using convertInput would be a good choice I guess but I have no idea how to
iterate over panel's components and read value
*
@Override
protected void convertInput()
{
List<String> accounts = getModelObject();*
????
*setConvertedInput(accounts);
}*
or maybe this is happening automagically :D ????
pozdrawiam

yep I did it like that and it works
public class Editor extends FormComponentPanel<List<String>> {
private ListView<String> item;
/**
* If you dont have ArrayList you can always copy your collection to new
ArrayList.
*
* @param id of the control
* @param accounts a list of all accounts assigned to the peron.
*/
public Editor(String id, IModel items) {
super(id, items);
buildComponents();
}
private void buildComponents()
{
setOutputMarkupPlaceholderTag(false);
add(new SimpleAttributeModifier("class", "editor-panel"));
final List<String> items = getModelObject();
item = new ListView<String>("item", items){
@Override
protected void populateItem(ListItem<String> listItem)
{
String number = listItem.getModelObject();
listItem.add(new NumberInput("number", number));
listItem.add(new RemoveButton("remove", number, items));
}
};
item.setReuseItems(true);
Link addButton = new Link("add"){
@Override
public void onClick() {
items.add("");
item.detach();
}
};
add(addButton);
add(item);
}
@Override
protected void onComponentTag(ComponentTag tag) {
tag.setName("section");
super.onComponentTag(tag);
}
@Override
protected void convertInput()
{
setConvertedInput(saveConvertedData());
}
private List<String> saveConvertedData()
{
final List<String> items = new ArrayList<String>();
item.visitChildren(NumberInput.class, new
Component.IVisitor<NumberInput>(){
@Override
public Object component(NumberInput component) {
String number = component.getConvertedInput();
items.add(number);
return Component.IVisitor.CONTINUE_TRAVERSAL;
}
});
return items;
}
}
thanks for help

Use a ListView instead of RepeatingView, it recreate its list item
components each render and it already resolve which value goes to which
component.

heh i thought I was smart :] as each component in FormComponentPanel is
converted and validated so it would be easy to intercept value set on
components model and add it to List (which is model of whole FCPanel)
because Im not really converting components value to something bigger.
the only problem is getting value for each component as interface is only
getObject and setObject so there is no information model could decide which
value goes to which component

You can set any model in your form component panel. But its value will be
set during the form processing, after the validation step.
FormComponent#convertInput is invoked before the validation step, and it
only sets the converted input in the FormComponent (see
FormComponent#setConvertedInput). It don't set the model already.

hej,
on the second thought I can implement (in this simple case) a model backuped
by List or Set and then let Form (or FormComponentPanel) to process all
fields.

Override convertInput is a good option. Keep in mind that at this point of
the form processing (converting input), component models will not be updated
yet. So you need to rely on children converted data
(see FormComponet#getConvertedInput) in order to assemble the
FormComponentPanel converted input.
In order to access your children components, you can use the visitor API,
e.g. MarkupContainer#visitChildren
