How to update an ajax form panel?
Hi, iam totally stuck and get confused at all.
In my DB-based application i want to use the common data-table-lists (this
works) with linked action (edit, delete, create what ever)
But i want to edit a clicked "entity" under my form. So i think i have to
use a panel for this form i want to update ...
http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd";>
http://www.w3.org/1999/xhtml";
xmlns:wicket="http://wicket.sourceforge.net/";
xml:lang="en"
lang="en">
Name
[Name]
But i cant figure out how to Fill this Panel right. Actual i tried it this
way:
public class MyPanel extends Panel {
public final String LABEL_NAME = "panel_name";
public MyPanel (String id) {
super(id);
add(new Label(LABEL_NAME));
// TODO Auto-generated constructor stub
}
public MyPanel (String id, Functionsbereich bo){
this(id);
this.setOutputMarkupId(true);
add(new Label(LABEL_NAME, bo.getLabel()));
}
}
and in my page
item.add(
new AjaxLink(
"action",
(IModel)
new LoadableDetachableModel() {
@Override
protected Functionsbereich load() {
return el;
}
}){
@Override
public void onClick(AjaxRequestTarget target) {
target.appendJavascript((String)
dialog.open().render());
target.addComponent(new FunctionsbereichPanel("content",
el));
}
});
but this don't work.. it always tell me that markup with ID "panel_name" is
still registered and has to be unique,
cause i have to define the panel initially as Member in my Page, else wise
the "No definition for markup 'panel_name' markup found" raises.
//Empty Panel
final FunctionsbereichPanel panel = new FunctionsbereichPanel("content");
I hope anyone understood my problem.
Thanks in Advance and apologise for my English, its not my mothers tongue.
Updating Form Elements by Ajax with new POJO-Model
Iam totally confused.
Iam using the Todo-List-Example from here :
http://www.wicket-library.com/wicket-examples/ajax/todo-list.0
to play around with wicket.
This example works, but i want to display a list of Entities from the
Backend and edit one of them with my "new-entity"-Form.
So i want to click on "edit" in a row and want to use the *same* *form *as i
use to add a entity. How could i handle this?
I tried sooo much but nothing works right.
The "addForm" (showForm(target)) function works right. But in public void
showForm(AjaxRequestTarget _t, Functionsbereich el)
i deliver "el" which is my POJO and i cant figure out how to treat the Form
to use now my new "Model"...
I tried with modelChange() und mondelChanging() but nothing works =( allways
the "empty Form" is shown ;(
Thanks a lot for any help!!
private final class FormContainer extends WebMarkupContainer{
private EditForm f;
public FormContainer(String id) {
super(id);
setOutputMarkupId(true);
add(f = (EditForm) new EditForm("form").setVisible(false));
add(new AjaxFallbackLink("link"){
@Override
public void onClick(AjaxRequestTarget target) {
showForm(target);
}
});
}
public void showForm(AjaxRequestTarget _t){
f.setVisible(true);
_t.addComponent(this);
}
/** Shows form with entity **/
public void showForm(AjaxRequestTarget _t, Functionsbereich el){
//add(f = new EditForm("link", el));
f.modelChanging();
f.setModel(new CompoundPropertyModel(el));
f.modelChanged();
f.setVisible(true);
_t.addComponent(this);
}
}
private final class EditForm extends Form{
public EditForm(String id){
this(id, new CompoundPropertyModel(new
Functionsbereich()));
}
public EditForm(String id, Functionsbereich _el){
super(id,new CompoundPropertyModel(_el) );
}
public EditForm(String id, CompoundPropertyModel
_model) {
super(id, _model);
setOutputMarkupId(true);
add( new TextField("form_text", _model.bind("label")));
//add(new Label("vendor", _model.bind("vendor.name")));
}
}
Howto load StringResources from Database for Iternationalization?
Hello Folks, i don't know if this question was ever done, but i didn't find anything suitable for me. In a huge webapplication which is being in the first steps of implementation, we want to use a Database (table) to store there any "String Resources" by locale for translation. I have been jumping through the class-hierarchy for many hours but i haven't found the right point to "plug-in" a ResourceLoader from Database. There are some different "Interface" of them i could imagine "This is the right place" but I am not sure at all. Have i to Implement my own *IResourceSettings*? I hope not, cause the Implementation "Settings" looks very complicated to me. or is it enough to implement *IStringResourceLoader*? But then, where can i add my own loader to the "Chain" of processing? Thanks a lot for any hints. Its very urgently to know and to understand if wicket is useful for our "wishes" before we really decide which framework we "want" to use. Please apologise for my English, its not my mothers tongue. - Matty
Easier using of FormComponentFeedbackIndicator for many fields?!
Hi Folks,
i've to implement many form-pages with a lot of (more than 30) input fields,
and each of them should be validated at least of "required" or not.
but the request is to show the validation-errors behind the depeding
component.. so iam using FormComponentFeedbackIndicator now and everything
works fine with:
searchfield = new RequiredTextField("seachfield", new
PropertyModel(SearchPanel.this, "searchString"));
add(searchfield);
indicator = new FormComponentFeedbackIndicator("searchfield_indicator");
indicator.setIndicatorFor(searchfield);
indicator.setOutputMarkupId(true);
indicator.setOutputMarkupPlaceholderTag(true);
add(indicator);
this is an ajax-form so i have to add this to onSubmit too for each
validating field.
protected void onError(AjaxRequestTarget target, Form form) {
target.addComponent(indicator);
}
Is there any Hint to easier this implementation?
What i imagine is something like:
searchfield = new *RequiredValidatedTextField*("seachfield", new
PropertyModel(SearchPanel.this, "searchString"));
and inside this child class iam building a indicator
but how could i add the "indicator"-Span dynamically to the markup and how
could i do the target.addComponent than?
Thanks for any hints.

How to add and remove css classes the right way?
Hi Folks,
I'am getting totally confused how to add and remove css classes to and form
my text-input-fields on ajax-form-validation.
At first i try to add two css classes step by step:
Iterator iter =
Session.get().getFeedbackMessages().messages(getFeedbackMessageFilter()).iterator();
if(iter.hasNext()){
indicatorFor.add(new SimpleAttributeModifier("class","validation_error"));
indicatorFor.add(new SimpleAttributeModifier("class", "test"));
}
But gets the Markup only with "class='test' "
How can i add more than one "value" to "class"?
And how can i remove one special css-class from an component if the
validation is okay to this field?
Thanks in Advance for any help.

Delegate a Modelchange to the child components. Or using a ModalWindow for displaying different Models of a specific Type.
Its not easy to find the right topic, but i will try to explain my problem
as best as i can.
I want to display an user-detail View (User is an BusinessObject in my
Application) inside a specific Modal window.
So at the rendering of the Site i place an "empty" or dummy UserObject
inside my UserEdit-Panel and later if the user choose one specific user from
a Table i want to replace this dummy-Model with the clicked-User-Model.
public class UserEdit extends Panel {
/**
* @param id
* @param model
*/
private IModel model;
CompoundPropertyModel cpm;
public UserEdit(String id, IModel _model) {
super(id, _model);
this.model = _model;
init();
}
private void init(){
cpm = new CompoundPropertyModel(this.getDefaultModelObject());
this.add(new TextField("lastname", cpm.bind("lastName")) );
}
}
I dont know if its the right choice to use a cpm ... but i think its the
proper way right?
The UserEdit is the "content" of my ModalWindow implementation so i bore up
the "show" method with a new Model-Parameter to delegate them to the Inside
Content...
(inside ModelOverlay.class)
public void show(final AjaxRequestTarget target, IModel model)
{
if (shown == false)
{
getContent().setVisible(true);
getContent().setDefaultModel(model); // <- my new Line ;o)
target.addComponent(this);
target.appendJavascript(getWindowOpenJavascript());
shown = true;
}
}
The Model inside "UserEdit" is changed. But how can i archieve that the
lastname-Textfield now displays the Value of getLastName() from the new,
submitted Model?
In my opinion i tried everything... tried to override the
"onModelChange"-Event and tryed to set the new Model with an Visitor of
every childfield... but than i
lost my "expression" from the CPM and only
pages.adminuserpage$u...@17eea10is shown inside the Textfield.
Thanks for any help. Am i totally lost.. or am i on the right way and few
steps before the solution?
I hope you understand my problem... if not so tell me and i will try to
explain it in another way or even better...
