Clear input form values
Hello,
I'm using Wicket 7.
Please help me with the following.
I have a test form, with only one input text field on it.
When pressing on a link, I need to have the values in the form cleared out.
This is the html and java code, but I could not make it work, the input
field just won't clear.
Name:
public TestPage(IModel model, final ReturnObjectPage returnPage) {
super(model);
this.returnPage = returnPage;
add(new TestForm("testForm", model));
}
class TestForm extends Form {
/**
*
*/
private static final long serialVersionUID = 1L;
public TestForm(String id, IModel model) {
super(id, model);
TextField txtName = new TextField("txtName", new
PropertyModel(getModelObject(), "name"));
add(txtName);
txtName.add(new AjaxFormComponentUpdatingBehavior("change") {
private static final long serialVersionUID = 1654345477970524731L;
@Override
protected void onUpdate(AjaxRequestTarget target) {
target.add(txtName);
}
});
txtName.setOutputMarkupId(true);
AjaxLink clearLink = new AjaxLink("clearLink", model)
{
/**
*
*/
private static final long serialVersionUID = 1L;
@Override
public void onClick(AjaxRequestTarget target) {
model.setObject(new TestBean());
TestForm.this.clearInput();
target.add(TestForm.this);
target.add(txtName);
}
};
add(clearLink);
}
@Override
protected void onSubmit() {
logger.info("OnSubmit");
}
}
Repeat every 2 rows in a table
Hello, I have in the html file, a table where I need to repeat every two rows. So, my table is backed by a bean, where the bean values fill 2 rows of the table. When new bean instance is created, I need to add new 2 rows to the table. Thank you
Re: Clear input form values
Hello,
The txtName field has the .setOutputMarkupId(true).
I have also added it to the form.
But it doesn't work howevere.
I have event tested adding it to the txtLink, but still no change.
However, the issue appears to come from the
txtName.add(new AjaxFormComponentUpdatingBehavior("change") {...}
If I comment out this part, the clear is done.
But I need to have this behaviour kept.
Could you please advise?
Thank you

Re: Clear input form values
Hello,
But that was it.
The code contained both the
txtName.setOutputMarkupId(true) and the
txtName.add(new AjaxFormComponentUpdatingBehavior("change") { ...
I will paste all the code again (I have now only added the
txtLink.setOutputMarkupId(true) and the TestForm.setOutputMarkupId(true); )
Thank you

Re: Repeat every 2 rows in a table
Hello Per, thank you for the links.
I have following html code:
Name
Code
Id
The Java code looks like this:
public TestPage(IModel model) {
super(model);
TestForm tst = new TestForm("testForm", model);
tst.setOutputMarkupId(true);
add(tst);
}
class TestForm extends Form {
/**
*
*/
private static final long serialVersionUID = 1L;
public TestForm(String id, IModel model) {
super(id, model);
List beans = Arrays.asList(new TestBean("Name1", "Code1", 1),
new TestBean("Name2", "Code2", 2));
add(new ListView("forEachItem", beans) {
/**
*
*/
private static final long serialVersionUID = 1L;
@Override
protected void populateItem(ListItem item) {
item.add(new Label("itemName", new PropertyModel(item.getModel(),
"name")));
item.add(new Label("itemCode", new PropertyModel(item.getModel(),
"code")));
item.add(new Label("itemId", new PropertyModel(item.getModel(), "id")));
}
});
}
@Override
protected void onSubmit() {
logger.info("OnSubmit");
}
}
The code crashes here because itemId belongs to another row.
Could you please advise?
Thank you

DropDownChoice with ChoiceRenderer
Hello,
I'm using Wicket 7.
I have this simple use case where I need to have a dropdownchoice, where to
display some values, but the model should retain other values.
I have done the following, however, the model always retains null.
So my dropdownchoice should display Code1 and Code2 but save in the model
the values C1 or C2. Instead it always saves null.
==HTML==
Name:
Code:
[Code]
==JAVA==
public TestPage(IModel model) {
super(model);
TestForm tst = new TestForm("testForm", model);
tst.setOutputMarkupId(true);
add(tst);
}
class TestForm extends Form {
/**
*
*/
private static final long serialVersionUID = 1L;
public TestForm(String id, IModel model) {
super(id, model);
TextField txtName = new TextField("txtName", new
PropertyModel(getModelObject(), "name"));
add(txtName);
txtName.setOutputMarkupId(true);
//choice
List lst = new ArrayList();
lst.add("C1");
lst.add("C2");
ChoiceRenderer renderer = new ChoiceRenderer("code") {
private static final long serialVersionUID = 8875819661197521211L;
@Override
public Object getDisplayValue(String arg0) {
return (arg0.equals("C1") ? "Code1" : "Code2");
}
@Override
public String getIdValue(String arg0, int arg1) {
return arg0;
}
@Override
public String getObject(String paramString, IModel> paramIModel) {
// TODO Auto-generated method stub
return null;
}
};
DropDownChoice code = new DropDownChoice("code", lst,
renderer);
code.setOutputMarkupId(true);
code.setModel(new PropertyModel(getModelObject(), "code"));
add(code);
}
@Override
protected void onSubmit() {
logger.info("OnSubmit");
System.out.println("Code=" + getModelObject().getCode());
}
}
==Bean for the MODEL==
public class TestBean implements Serializable{
/**
*
*/
private static final long serialVersionUID = 1L;
private String name;
private String code;
private Integer id;
public TestBean(String name, String code, Integer id) {
this.name = name;
this.code = code;
this.id = id;
}
public TestBean()
{
this.name = "";
this.code = "";
this.id = null;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getCode() {
return code;
}
public void setCode(String code) {
this.code = code;
}
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
}
Re: DropDownChoice with ChoiceRenderer
:) yes, that was it:
@Override
public String getObject(String paramString, IModel> paramIModel) {
return paramString;
}
solved it:)

Check Group selected items called from other form loses the checked values
Hi,
I have 2 forms.
Bottom form = testForm
- I have a listview with checkboxes.
As I needed a checkAll control also, I have uses CheckGroup,
CheckGroupSelector and Check wicket components.
Top form = testForm0
-I have only an link
The use case is the following:
I check one item (or all) in bottom form, but then I need to get the
selected values when click on link in top form.
The check doesn't do submit so the values are not retained. I alsways get
the
size = 0 message.
Could you tell me how I can manage this?
Here is the code:

Re: Check Group selected items called from other form loses the checked values
Hello,
I have actually made this to work by adding this behaviour to the
checkgroup:
group.add(new AjaxFormChoiceComponentUpdatingBehavior() {
private static final long serialVersionUID =
1654345477970524731L;
@Override
protected void onUpdate(AjaxRequestTarget target) {
target.add(group);
}
});
However, now I face following issue:
If I replace my ListView component, with a RefreshingView, I cannot check
any of the checks from the items. I check it, but then it gets unchecked
right away.
This is because the RefreshingView repaints its model at every roundtrip to
the server.
I have tried this:
http://stackoverflow.com/questions/12282492/add-row-to-refreshingview-without-repainting-entire-refreshingview
by setting:
listOfItems.setItemReuseStrategy(new ReuseIfModelsEqualStrategy());
But it did not change a thing for me.
Please guide on how to have a Check for every item of the RepeatingView,
that can be checked.
Thank you.

Re: Check Group selected items called from other form loses the checked values
Hello, Thank you for the samples.
But I will explain again what I have:
I have two forms on my page.
In the bottom form I have a RefreshingView component, with check all
checkbox in the header, and check components for each items.
In the top form there is a link, where I need to get the checked items from
the second form (the bottom form);
This is what I have done:
For checkAll and the individual checks I have used CheckGroup,
CheckGroupSelector and Check.
The issue is that because the refreshing view refreshes the model at every
server roundtrip, when I check on item, the check doesn't maintain it's
value, because it receives every time a new model.
So this bit from the RefreshingView always returns a new model which makes
the checks to dissapera:
@Override
protected Iterator> getItemModels() {
List lst = SpringCtx.getAppDB(TestBeanDao.class).selectAll();
List> models = new ArrayList>();
for (TestBean tstSN:lst) {
IModel modTst = new Model(tstSN);
models.add(modTst);
}
return models.iterator();
}
Isn;t there any way that I can still use the CheckGroup and Check
components? As this comes easy when it is needed a CheckAll functionality.
Thank you

AutocompleteTextField on submit : The value of .. is not a valid ...
Hi,
Please help me with following issue:
I'm using wicket 7.
I have a form with a AutocompleteTextField.
The autocompletion works ok until I need to submit the form, when I get
following message:
- The value of 'test' is not a valid TestBean.
Here is my component:
IAutoCompleteRenderer testRenderer = new
IAutoCompleteRenderer() {
private static final long serialVersionUID = -7038764178796856779L;
@Override
public void render(TestBean object, Response response, String criteria) {
response.write((new StringBuilder()).append("").toString());
response.write(object.getUniqueName());
response.write("");
}
@Override
public void renderFooter(Response response, int ItemId) {
response.write("");
}
@Override
public void renderHeader(Response response) {
response.write("");
}
};
AutoCompleteTextField txt = new
AutoCompleteTextField("test", new PropertyModel(this,
"myTestBean"), TestBean.class,
testRenderer, (new AutoCompleteSettings().setPreselect(true))) {
private static final long serialVersionUID = 1L;
private List TestList = null;
@Override
protected Iterator getChoices(String input) {
if (Strings.isEmpty(input)) {
return Collections.emptyIterator();
} else {
if (input.length() > 0) {
if (TestList == null || TestList.isEmpty() || !input.substring(0,
1).toUpperCase().equals(TestList.get(0).getUniqueName().substring(0,
1).toUpperCase())) {
TestList =
SpringCtx.getAppDB(TestBeanDao.class).selectAproxByUniqueName(input.substring(0,
1));
}
}
}
int autoCompleteFieldNumChoices = 20;
List choices = new
ArrayList(autoCompleteFieldNumChoices);
for (int i = 0; i < TestList.size(); i++) {
final TestBean testBean = TestList.get(i);
final String testName = testBean.getUniqueName();
if (testName.toUpperCase().startsWith(input.toUpperCase())) {
choices.add(testBean);
if (choices.size() == autoCompleteFieldNumChoices) {
break;
}
}
}
return choices.iterator();
}
};
How to access wicket parent page wicket:message
[pageTitle] Hi, I'm using wicket 7.5. I have a parent page, and child pages that extend it: In my child .properties pages, I always had the pageTitle=My Titile. I now need to dinamically change the title of the page, inside my child page constructor. Could you please advise? Thank you
Re: How to access wicket parent page wicket:message
Hello,
Could you please provide an example?
I have added the below line in my constructor, but nothing appears where
the title should be.
add(new Label("pageTitle", new ResourceModel("pageTitle", "my title")));
In the child .properties files I have left the pageTitle empty: pageTitle=
In the child .html page, I haven't added anything.
Thank you.

Re: How to access wicket parent page wicket:message
Hello again,
So I need to change the parent page markup?
I was thinking if there was a way to not change anything in the parent
page...
So my parent page html contains this markup:
[pageTitle]
I need in my child pages, to be able to dinamically change the title. Until
now, every child page had a pageTitle property in the .properties file
and that was setting the title.
But now, I have a situation where I need to open up the same child page
with different titles, based on some condition.
Thank you

DataTable with input columns, refresh values shown in other columns
Hello, I'm using wicket 7.5. I have a DataTable, where one of the columns is an input textfield with a clickable icon near it. When providing data for the input field, and clicking the icon, some validations are done, and the fields for other columns should be updated accordingly. However they are not updated at all. Could you please advise how I can implement this? Thank you.
Re: DataTable with input columns, refresh values shown in other columns
Hello, thank you for the help.
It did solve some of the situations, but not all of them.
Here is where I still face issues.
In my table row, I have an input field and a icon near it. I insert text
into input field and press the icon (AjaxLink component).
1. If data exists in the db for that input value, the data is shown in
others columns - OK, this works now.
2. If data does not exist in the db for that input value, a popup window
opens allowing to insert the new values - NOK
This does not work because when coming back from the pop window the row
is not refreshed with the new inserted values in the db.
3. on change event of the input, the data from the others row cells should
be emptied - NOK, this does not work either.
//this is how I get the row
MarkupContainer row = cellItem.findParent(Item.class);
//change event
txt.add(new AjaxFormComponentUpdatingBehavior("change") {
private static final long serialVersionUID = 1654345477970524731L;
@Override
protected void onUpdate(AjaxRequestTarget target) {
getModelObject().setValue1(null);
getModelObject().setValue2(null);
target.add(row);
}

Re: DataTable with input columns, refresh values shown in other columns
Hello,
2) Yes, the target.add(row) is on the callback from the modalWindow.
3) yes, I need to update the other values after user leaves the input, I
don't want immediate changes after each character change.
While in debug mode, I can see the change event being called, and the all
the values set to null, but the row is still not getting updated.

Datatable with drop down choice
Hello, Could you please advise what would be the best option to have in my DataTable, a column, where the cells contain a drop down choice? Thank you
Iterate through lines from datatable with editable columns
Hello, I m using wicket 7.5. I have a datatable, where some of the columns contain editable components: -dropdownchoices -checkboxes -TextFields After I edit some of the editable cells, when hitting a process button, I need to iterate through all lines from the datatable and save the changes. But I cannot see the changes. The initial values always appear. Could you please advise on how I can iterate through a DataTable, and get the values of the cells as they are shown? Thank you.

Form with backing loadabledetachable model
Hello, I have a list of items in a Refreshing View. When I click on a link inside the Refreshing View, a form in the same page should get populated with the values from the line. I have managed to do this, by having inside the Form a LoadableDetacheableModel and then use this model as backing model for the components in the form. However, I have also a drop down inside the form, but when changing the value, the LoadableDetacheableModel does not get updated with the new value. Or if using getModelObject(), all values are null, because, the backing model of the form is null. Could you please advise? Thank you
Re: Form with backing loadabledetachable model
Hello,
=Here is the RefreshingView link item. When clicking on this link, the form
should be filled with the values of this RefreshingView line.
When click on the link, I set the property itemmodel with the line model.
The itemmodel is then used by the LoadableDetacheableModel, to get the
values for the form.
// edit link
AjaxLink linkEditItem = new AjaxLink("linkEditForm", model)
{
private static final long serialVersionUID = 15L;
@Override
public void onClick(AjaxRequestTarget target) {
feedbackPanel.getFeedbackMessages().clear();
editForm.clearInput();
editForm.setItemmodel(new Model(item.getModelObject()));
target.add(editForm);
target.add(feedbackPanel);
}
};
=Here is the form:
class EditForm extends Form {
/**
* Form where you can edit the items from the list
*/
private static final long serialVersionUID = 1L;
private IModel itemmodel;
public void setItemmodel(IModel itemmodel) {
this.itemmodel = itemmodel;
}
public EditForm(String id, IModel model) {
super(id, model);
this.itemmodel = model;
final LoadableDetachableModel poItemsListModel = new
LoadableDetachableModel() {
private static final long serialVersionUID = 0L;
@Override
protected MyBean load() {
return itemmodel.getObject();
}
};
// Edit ITEMS
final WebMarkupContainer editContainer = new
WebMarkupContainer("editContainer");
editContainer.setOutputMarkupId(true);
add(editContainer);
final MyBean tst = poItemsListModel.getObject();
// unrepairable
DropDownChoice unrepairable = new
DropDownChoice("unrepairable", lstSN, renderer) {
private static final long serialVersionUID = 1L;
*@Override*
* public boolean isEnabled() {*
* return (tst.getId() == null || (tst.getIrreparableSal() != null &&
!tst.getIrreparableSal().equals("S")));*
* }*
};
unrepairable.setModel(new PropertyModel(poItemsListModel,
"irreparableSal"));
unrepairable.setOutputMarkupId(true);
editContainer.add(unrepairable);
unrepairable.add(new AjaxFormComponentUpdatingBehavior("change") {
private static final long serialVersionUID = 1L;
@Override
protected void onUpdate(AjaxRequestTarget target) {
target.add(unrepairable);
}
});
In this piece of code(also in bold above), I cannot ever get the actual
values of my LoadableDetacheableModel; they are always null, they never get
updated with the values of the line.
*@Override*
*public boolean isEnabled() {*
* return (tst.getId() == null || (tst.getIrreparableSal() != null &&
!tst.getIrreparableSal().equals("S")));*
*}*

ListView color background lineitem dinamically not working
Hello,
I have a listview and I want to dinamically color some of the rows (items).
But it is not working, nothing gets colored when it should.
*Here is the markup:*
[item1]
[item2]
[item3]
[item4]
[item5]
[item6]
[item7]
[item8]
[item9]
[item10]
Area
*Here is the code:*
@Override
protected ListItem newItem(final int index, IModel model) {
return new ListItem(index, getListItemModel(getModel(), index)) {
@Override
protected void onComponentTag(final ComponentTag tag) {
Items line = getModelObject();
if (line.getIdLn() == 6)
tag.put("style", "background-color:green");
else if (line.getIdLn() == 4 )
tag.put("style", "background-color:red");
// continue with default behavior
super.onComponentTag(tag);
}
};
}
Could you please advise?
Re: ListView color background lineitem dinamically not working
Thank you so much for you explanation.
I had to put the two inside the because I need to
repeat every two rows.

Thank you so much for you explanation.
I had to put the two inside the because I need to
repeat every two rows.
Do you have any hint on how to do it and still be able to change the color?
