Re: Feedback within Form Weird Issue
Try with binding the session. Maybe you run in stateless mode.

I do have a function that gets the session and register the error to it. Can the feedback be apart of the form? I have tried it outside the form with no luck either.

Re: Server and client side validation
Hi Gabriel,

Hi Martin,
It does work with the following code:
/return $('#%s').closest('form').parsley( 'validate' );/
Thank you very much.
To find out whether the form is in a ModalWindow or not, I've used the
following code:
/@Override
public void renderHead(final IHeaderResponse varResponse) {
super.renderHead(varResponse);
// starts parsley for this form
if (this.findParent(ModalWindow.class) == null) {
I think you should look for the root form instead of a ModalWindow.
You can have nested forms in your app without ModalWindow around.
See org.apache.wicket.markup.html.form.Form#findForm
and org.apache.wicket.markup.html.form.Form#getRootForm
varResponse
.render(OnDomReadyHeaderItem.forScript(String.format($('#%s').parsley();,
this.getMarkupId(;
} else {
varResponse.render(OnDomReadyHeaderItem.forScript(String.format($('#%s').closest('form').parsley();,
this.getMarkupId(;
}
}/
Is there a better way to do that, or is it OK?
Regards,
Gabriel.

Just add this to your class and it should work.

RE: form processing adding new inputs with an ajax onupdate
Hi Paul, Thanks for your suggestion, hadn't tried that, but I have now and it doesn't fix my problem. I use the idiom rather than simply calling Because: 1. depending on the situation it can lead to many setVisible calls in different parts of the page 2. it localises the visible setting to the component to which it applies 3. i don't need to pepper the code with lots of references to the component whose visibility is to be set 4. http://wicketinaction.com/2011/11/implement-wicket-component-visibility-changes-properly/ Thanks anyway for your suggestion, Cheers Simon -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/form-processing-adding-new-inputs-with-an-ajax-onupdate-tp4658758p4658778.html Sent from the Users forum mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
RE: form processing adding new inputs with an ajax onupdate
Hi Paul, I was mistaken. I apologise. Previously I hadn't completely removed the onConfigure method from the form component and simply called the setVisible in the onUpdate method of the AjaxFormComponentUpdatingBehavior(onchange) / AFCUB(onchange). So your suggestion worked! Thank you very much. I would still really like to understand why the onConfigure way of setting the visibility of the component didn't work, does anybody have any idea about this?

Re: Deserialization InvalidClassException : no valid constructor
This could only work if BufferedImage itself had a no-arg constructor.
It is it the first non-serializable class in the hierarchy that needs to
have it,
not the first serializable one, like in your example.
Besides, you would still lose all data stored in the BufferedImage's fields
(i.e.
the image stored in it).

Today I encountered one famous deserialization problem :
InvalidClassException : no valid constructor
I googled and found some solution , but all are in-vain.
The solution says the first non-serializable super class should define a
no-arg constructor.
But I try to define a no-arg constructor to EACH class of the HIERARCHY ,
and EACH class implements Serializable... (which is not necessary , but I
want to make it simple , to pinpoint the problem)
My base class is an abstract class extends BufferedImage (java 2D)
while BufferedImage is not Serializable
So I make my abstract class implements Serializable and define a no-arg
default constructor.
The total hierarchy is :
public abstract class AbstractChart extends BufferedImage implements
Serializable {
public AbstractChart() {// I try to remove this constructor ,
but in vain
super(0 , 0, TYPE_INT_ARGB);
}
}
and first child class :
public class ChildChart extends AbstractChart implements Serializable {
public ChildChart() {
super(); // or not calling super()
}
}
and the grandson class :
public class GrandsonChart extends ChildChart implements Serializable {
public GrandsonChart() {
super(); // or not calling super()
}
}
No matter I calls super() in ChildChart or GrandsonChart ,
Caused by: java.io.InvalidClassException: foobar.GrandsonChart; no valid
constructor
It happens when I click a button ,use ajax to paint this GrandsonChart ,
and click another page , and use browser back .
The browser will be redirected to /context/wicket/page?xxx (The error page)
The screen shows :
Could not deserialize object using:
class
org.apache.wicket.serialize.java.JavaSerializer$ClassResolverObjectInputStream
and in the console log , I can see this InvalidClassException is thrown.
Any way to solve this problem ?
(I've already added default no-arg constructor , and make each class
implements Serializable , but still not working )
environment :
Wicket version : 6.7
Resin 4.0.25
Java HotSpot(TM) 64-Bit Server VM 20.4-b02-402, 64, mixed mode, Apple Inc

Agreed.
We can pre-register all known tags like: panel, border, head, container,
etc.
No need to do this lazily.
org.apache.wicket.markup.parser.filter.WicketTagIdentifier#wellKnownTagNames
is a static HashSetString. It won't be too much memory consumption.

I'm trying to override the markupSourcingStrategy because i want
this
class
to have it's own html file. Anybody an idea? I use wicket-core
6.7.0.
This is my java file:
public class ExtBookMarkablePageLinkT extends
BookmarkablePageLinkT {
private final Component label;
public C extends Page ExtBookMarkablePageLink(String id,
ClassC
pageClass) {
this(id, pageClass, new PageParameters()); } public C extends
Page
ExtBookMarkablePageLink(String id, ClassC pageClass, final
PageParameters
parameters) { super(id, pageClass, parameters); add(label =
newLabel(label)); }
protected Component newLabel(final String markupId) {
return new Label(markupId, new
ModelString()).setRenderBodyOnly(true);
}
@Override
protected IMarkupSourcingStrategy newMarkupSourcingStrategy() {
return
new
PanelMarkupSourcingStrategy(true);
}
public ExtBookMarkablePageLinkT setLabel(IModel? label) {
this.label.setDefaultModel(label);
return this;
}
}
and this my html file:
!doctype html
html xmlns:wicket=http://wicket.apache.org;
wicket:panel
span wicket:id=label/span
/wicket:panel
Re: Feedback within Form Weird Issue
Thanks I will try both things. I believe my pages are stateful.

Component twice in markup while ajax refresh in Wicket 6.7 (migrated from 1.5.10)
Hi
I migrated my application from Wicket 1.5.10 to 6.7
During testing I recognized that during an ajax update (replacement) of a
component, the markup of the component is twice in the HTML markup (the old
and the new markup). Thus the execution of javascript inside a component may
fail due to the fact, that two components with the same id are present in
the HTML markup.
EXAMPLE
*HTML:*
lt;a wicket:id=quot;testlinkquot;gt;testlinklt;/agt;
lt;div wicket:id=quot;testboxquot; style=quot;width: 100px; height:
100px; border: 1px solid #ccc;quot;gt;
lt;script type=quot;text/javascriptquot;gt;
alert(#39;hello#39;);
lt;/scriptgt;
lt;/divgt;
*JAVA:*
final WebMarkupContainer testbox = new WebMarkupContainer(testbox);
testbox.setOutputMarkupId(true);
add(testbox);
add(new AjaxLinkVoid(testlink) {
private static final long serialVersionUID = 1L;
@Override
public void onClick(AjaxRequestTarget target) {
target.add(testbox);
}
});
So while the ajax update is processed the 'testbox' DIV and its javascript
are present twice (the old and new DIV). If the javascript is a little more
complex and for example changes stuff inside the DIV, the javascript will
change stuff in the old instead of the new DIV container.
My javascript relies on the fact, that an id should always be present just
once.
Why is the old DIV not removed first, before the new DIV is appended? Can I
change this behavior somehow?
Thanks in advance
Nico

Re: Component twice in markup while ajax refresh in Wicket 6.7 (migrated from 1.5.10)
Hi,
We use
https://github.com/apache/wicket/blob/master/wicket-core/src/main/java/org/apache/wicket/ajax/res/js/wicket-ajax-jquery.js#L1617
because
it is faster than jQuery#replaceWith().
So yes, there is a small period when both the old and the new are in the
DOM.
As Sven asked - please create a quicktart and attach it to a ticket so we
can see whether we will find a solution or we will have to use the slower
way to replace.

Agreed.
We can pre-register all known tags like: panel, border, head, container,
etc.
No need to do this lazily.
org.apache.wicket.markup.parser.filter.WicketTagIdentifier#wellKnownTagNames

You are correct.
I have no idea why it failed for Andy the first time.
Now I realize what happens.
The usage of Panel.PANEL is inlined in PanelMarkupSourcingStrategy at
compile time, i.e. its String value is put in the place of the
constant.
That's why it doesn't trigger the static initializer.
since it's referring a constant of panel . yes but i agree not a
very

code flow so should be improved ,i always used to think they are

this in a very weird way :-)

Get rid of your newMarkupSourcingStrategy() override and place

This will not work because usually Link component has no its own

See Panel.java. It has:
static
{
// register wicket:panel
WicketTagIdentifier.registerWellKnownTagName(PANEL);
}
Just add this to your class and it should work.
I think this is a bug in Wicket though - this piece of code
should
be
executed by PanelMarkupSourcingStrategy, not by Panel itself.
Feel free to file a bug report.

Re: Attaching Ajax Function to Java Method
Select2's wicket integration should provide you with some pointers [1]. It basically points down to implementing a listener interface, and providing the url to it to your javascript code. You can then return your data when the listener interface's method is called.

Re: Attaching Ajax Function to Java Method
The following seems to work (using wicket 6.7 with the experimental bootstrap
module). Basically, this ajax behavior is called on page load. At that
point, it writes out the javascript to initialize the object with typeahead
parameters.
HTML:
input wicket:id=typeahead type=text data-provide=typeahead
data-items=4
JAVA:
add(new TextFieldString(typeahead).add(new TypeAhead()));
TypeAhead Behavior:
import org.apache.wicket.Component;
import org.apache.wicket.ajax.AbstractDefaultAjaxBehavior;
import org.apache.wicket.ajax.AjaxRequestTarget;
import org.apache.wicket.markup.head.IHeaderResponse;
import org.apache.wicket.markup.head.OnDomReadyHeaderItem;

public class TypeAhead extends AbstractDefaultAjaxBehavior {

}

String sources = toJSONArray(getOptions());
String script = String.format($('#%s').typeahead( { source: %s } );,
getComponent().getMarkupId(), sources);
target.appendJavaScript(script);
}
@Override
public void renderHead(Component component, IHeaderResponse response) {
super.renderHead(component, response);
response.render(OnDomReadyHeaderItem.forScript(
this.getCallbackScript() ));
}
// OVERRIDE THIS TO SUPPLY LIST OF OPTIONS
public ListString getOptions() {
return Arrays.asList( new String[] {Alabama, Aftermath, Absinth}

}
// There's probably a built-in method that does this…
private String toJSONArray(ListString strings) {
StringBuffer result = new StringBuffer([);
for (String string : strings) {

result.append(',);

Re: Attaching Ajax Function to Java Method
@Bas Gooren that code you linked was very helpful. I have what I want
up and working, but it's using a bunch of ugly jQuery ajax callbacks
hacked into StringBuilders :-(
@Don Ferguson I don't *think* this is what I'm looking for as I have
thousands of options and I don't want them rendered at page load.
Instead I want to register a function that will call-back to my Java
code when someone start typing and allows me to search. However, I did
not run it, just looked at the code.
Here is what I have, again it's ugly. Does anyone know how I can
clean-up the jQuery.ajax stuff? I've gotta imagine there is a way to
do it in Wicket.

Have you tried to implement just the Save link/button and then look-up the
model object from inside the onClick() method?
In your case it would come from the PropertyModel you use already:
TextField description = new TextField(description,new
PropertyModel[Meeting](meeting, description))
change to:
IModel descriptionModel = new
PropertyModel[Meeting](meeting, description));
TextField descriptionTextField = new TextField(description,
descriptionModel );
and your link becomes:
private class LinkSave(id: String, meeting: Meeting) extends
AjaxLink[String](id) {
@SpringBean
var meetingMediator: TMeetingMediator = _
def onClick(target: AjaxRequestTarget) {
meetingDAO.saveMeeting(descriptionModel.getObject())
}
}
Unless you want to also update some other element on the screen with each
user key press I really don't think you need the keyup listener.
~ Thank you,

I'm trying to implement a ListView and in on column of it I added a
listView, for each line,
I want to save the data inserted on it and update the model:
I'm implemented the code bellow:
val description = new TextField(description,new
PropertyModel[Meeting](meeting, description))
description.add(new AjaxFormComponentUpdatingBehavior(keyup) {
protected def onUpdate(target: AjaxRequestTarget) {
description.getDefaultModelObjectAsString
}
})
item.add(description)
And I added a link for each line of my ListView for save the information
in
database,
each line is a instance of a model meeting as is showed bellow:
item.add(new LinkSave(save, meeting))
private class LinkSave(id: String, meeting: Meeting) extends
AjaxLink[String](id) {
@SpringBean
var meetingMediator: TMeetingMediator = _
setVisible(clickavel.asInstanceOf[Boolean])
add(new Label(label, new Model[String]() {
override def getObject: String = Save
}))
def onClick(target: AjaxRequestTarget) {
meetingDAO.saveMeeting(meeting)
}
}
But unfortunately the code above doesn't work. It's fail to retrieve the
value of the text
field and also to set the attribute description of the Object meeting
with
the value of the text field, so in the database the column description is
never filled
Someone know where I am doing wrong stuff?
Thanks a lot!

Ill really apreciate the help to get the selected item of a DropDownChoice using Scala
Hi For some weeks I'm trying to implement a simple combobox, DDC, and I'm struggling with this. I asked for some help several times but unfortunately I didn't archive my goal because I'm failing sometimes to understand scala with wicket, I have a little background with them at the moment. Anyway, my code is showed bellow: *// ComboBox in a listView item.add(new DropDownChoice(customerSelection, new PropertyModel[Customer](customer, name), listCustomer, new ChoiceRenderer[Customer](name))* If I create a variable, for example,* val custName*, to receive the name of the selected customer which functions I need to implement on the creation of DDC object and how can I retrieve this value for the variable? Thanks very much for help me.
