RE: How to fail validation if ListMultipleChoice is empty

[Coleman, Chris]

That was my plan exactly but I didn't know of a way to tell which button was 
doing the form submission until now!

Thanks for that Form#findSubmittingButton works beautifully!

I don't even think it's a hack as that validation should only really a problem 
if the user is submitting the form, not when they are merely adding items to 
the list.

We are using models for the storage of which items are in the list when the 
user clicks OK.
We are also using models to keep track of which items the user has selected 
(multiple selection is turned on).

The form is a classic 'tranfer' setup - with 2 list boxes and 2 buttons 
add/remove. The user can transfer items from one list to the other.

Good catch on AjaxSubmitButton being deprecated, I guess an IDe would have
made that obvious ;)

I do have to say using the getChoices over a proper model may give you more
work than needed in updating the underlying model objects (maybe consider
overriding the getConvertedInput to return getChoices)

It sounds like you have different buttons for adding and submitting. Correct
me if this is too hackish, but you could change the validator to check if
the addBtn is the submitting button, and ignore the validation in that case:

  form.add(new AbstractFormValidator()
  {
public FormComponent[] getDependentFormComponents()
{
  return null;
}

public void validate(Form form)
{
  List sets = targettedSetsList.getChoices();

  if ((*!addBtn.equals(form.findSubmittingButton()) &&* sets.size() == 0
) {
targettedSetsList.error((IValidationError)new
  ValidationError().addMessageKey("error.noSetSpecified"));
  }
}
  });

Re: wicket 1.5 AbstractDefaultAjaxBehavior bad url

[msj121]

SOLVED:

After some debugging I noticed the following:

In the constructor the url generated is:
./wicket/page?54-0.IBehaviorListener.0

In onBeforeRender and onAfterRender the url is
./wicket/page?54-1.IBehaviorListener.0

I was pretty much getting the url as a string and passing it to WiQuery (ie:
another object). When the url is finally updated after the constructor (ie:
later in the request cycle) the string was obviously not altered though the
url was no longer good.

Furthermore, reloading the page doesn't always seem to call the constructor
leaving a further off url. Meaning the string stored was for a previous
version number so it might be 52-0 instead of the intended 53-1 etc


This may be obvious to someone who understood the url changes even after the
constructor of the page was called. I suppose it boggled me as this is only
an issue now in Wicket 1.5 somehow.

RE: How to fail validation if ListMultipleChoice is empty

[Coleman, Chris]

According to the doco the default form processing behavior is executed for 
AjaxButton and AjaxSubmitButton (in fact AjaxSubmitButton appears to be 
deprecated - behaves the same as AjaxButton anyway?).

I am using AjaxButton.

I actually don't care about the selections but rather, the entries that the 
user has added to the list (whether selected or not) which is why I call 
getChoices() rather than getConvertedInput()

The button code is:

  AjaxButton addBtn = new AjaxButton("add") {
@Override
protected void onSubmit(AjaxRequestTarget target, Form form) {
  update(target, selectedAvailableSets, availableSetsList, 
targettedSetsList);
}

@Override
protected void onError(AjaxRequestTarget target, Form form) {
}
  };

  addBtn.setOutputMarkupId(true);

  add(addBtn);

Re: DataTable's view does not always update

[Clint Checketts]

Make sure that sendredirect.compatibility property is set to false or
deleted. It causes problems. You didn't say if it had originally be set or
not though, lets make sure it didn't get left on at some point.

Watch the URL, if you typed in http://localhost/myApp and it renders as
http://localhost/myApp/*myApp* (note the duplicate context root) you could
get 404s.

Also convert to using the WicketServlet, WAS had trouble pointing to a
filter as an endpoint (unless you have an empty index.htm file). Lets see if
that gets you back on track. I suspect that is why your clean app isn't
working, you have no index.htm file to trick WAS into working.

Re: How to fail validation if ListMultipleChoice is empty

[Clint Checketts]

You are correct that the Form's validation should only fire when submitting
the form. When an individual element is updated via ajax (as in an
AjaxFormComponentUpdatingBehavior) then just the processing and validations
steps are fired for the individual form component.

It makes me wonder if you are using an AjaxSubmitButton instead of just an
AjaxButton. (Or similarly an AjaxSubmitLink instead of an  AjaxLink) Mind
including your button's code?

Also, why are you calling getChoices() instead of getConvertedInput() in the
validator? Choices represent the possible selection options, the converted
input is the value of the selected choices.

RE: How to fail validation if ListMultipleChoice is empty

[Coleman, Chris]

Yes, it's all via AJAX.

In the last few minutes I've tried a different approach and it works ok but it 
introduces another problem:

  form.add(new AbstractFormValidator()
  {
public FormComponent[] getDependentFormComponents()
{
  return null;
}

public void validate(Form form)
{
  List sets = targettedSetsList.getChoices();

  if ( sets.size() == 0 ) {
targettedSetsList.error((IValidationError)new 
ValidationError().addMessageKey("error.noSetSpecified"));
  }  
}
  });

This accurately detects when nothing is in the list and displays an error 
message but once emptied we can not add new elements to the list because the 
validation is also executed when the 'add' button is pressed. The validation 
fails because the list is empty so the 'add' fails, making it impossible to add 
new elements when the list is empty.

I thought validation would only occur when the user submits the form but it 
appears to be fired off whenever the user presses the 'add' button. Is this to 
be expected?

Lets see the code about 'adding elements by pressing on a button'.  The
'getValue()' method is returning the value from the list box's HTTP
submitted values, if the add button is submitting values via ajax or some
other means then it may need a different approach.

Re: DataTable's view does not always update

[D D]

I have a filter in web.xml file - however I did not set it up. At the
same time I've started to question the setup because I tried to deploy
a "clean" test app (by clean I mean new ear file for the test app and
no extra ear files and configuration - just a strip down example from
wicket's website) and I'm getting 404 trying to bring the application
up.

So the original application with problem is having 404 on ajax calls
but it will start up. Test app will not start up - shows 404 all the
time.

Is it a WAS setup issue?

Thanks,
Dave

Re: How to fail validation if ListMultipleChoice is empty

[Clint Checketts]

Lets see the code about 'adding elements by pressing on a button'.  The
'getValue()' method is returning the value from the list box's HTTP
submitted values, if the add button is submitting values via ajax or some
other means then it may need a different approach.

Re: DataTable's view does not always update

[D D]

I tried the setting with true and false settings. It still doesn't work.

Here is Ajax Debug
INFO: Initiating Ajax GET request on
?wicket:interface=:0:dataForm:dataPanel:rxEntryTabs:panel:link::IBehaviorListener:0:-1&random=0.6781234819490185

ERROR: Received Ajax response with code: 404

I also traced through debug the response sent to HttpResponse object
and it's what I'm expecting:

“

Not only it's written but the response object is properly closed too.
Not a single exception is thrown in Wicket's code.

The problem has to be somewhere inside WAS processing, right?

Any ideas where?

How to fail validation if ListMultipleChoice is empty

[Coleman, Chris]

We have an app that allows people to add elements to a ListMultipleChoice by 
pressing on a button. We want the form to fail validation if the 
ListMultipleChoice contains no elements.

I've tried this:

  targettedSetsList.add(new IValidator()
  {
public void validate(IValidatable validatable) {
  // Always contains no items - strange
  Collection list = (Collection)validatable.getValue();

  if ( list.size() == 0 ) {
ValidationError ve = new ValidationError();
ve.setMessage("No sets have been specified for deployment");
validatable.error(ve);
  }
}
  });

but at validation the list.size() is always 0 even if the user has added 
elements. Am I doing it the right way? Is there a better way?

Re: SubmitLink with confirmation dialog

[Pedro Santos]

Hi, SubmitLink already write some JavaScript in the onclick handler, so you
need to prepend the confirmation JavaScript in order to maintain the default
behavior. e.g.

submitLink.add(new Behavior() {
onComponentTag() {
tag.put("onclick", "if(!confirm('c')) return false;" +
tag.getAttribute("onclick"));
}
});

In Wicket 1.5 RC4 you can also use the AttributeAppender to prepend the
confirmation JavaScript.

Re: Ajaxifying existing application

[meduolis]

Use ajax with responsibility. To much ajax can make bad things :]. I can not
undestand, why you would like to change page to panel, and rerender it all,
just like setResponcePage does. Try to sit and decide, which parts of page
should be ajaxified and which should be left as it is.--

However, weather I click 'Cancel' or 'OK', the code in the onSubmit() method

Re: Ajaxifying existing application

[splitshade]

Hi James, yes, thats exaclty what I meant.

The Problem is, we have an existing infrastructure, that depends on pages.

The idea to change everything to a "setResponsePanel"-Method seems to be
very good, I think we could realize that very cheaply, thanks for the hint!

Would that be something that could be of interest for the framework itself?
Would it be possible/reasonable to integrate that into an
AbstractAjaxWebPage or something?

I did not try this out, but it seems to be a good idea that could be of
interest to many people?

Regards

Martin

SimpleAttributeModifier("onclick", yourJsHere) is the way if you want
to use JavaScript alert(). onSubmit() method is called at server side
only if onclick at the client side returned true.

Hi there,
I have a SubmitLink and I'd like to add a very simple confirmation dialog to

I've tried to add a SimpleAttributeModifier, but it overwrites the behaviour

Re: Table repeater: repeat across row AND column

[Martin Grigorov]

I like your current approach better than what you want to do.
Anyway here is how to do it:

int currIndex = item.getIndex();

ListItem nextItem = get(Integer.toString(currIndex + 1));
if (nextItem != null) {
...
}

Table repeater: repeat across row AND column

[Alexandros Karypidis]

Hello,

I am trying to create a web page that lists contact addresses in a table.  
My repeater can easily lay out one address per row, but I need to be able  
to list 2 addresses per row (actually, ideally I'd like to list N  
addresses per row). The problem is that ListView's operation  
[populateItem()] only provides you with one item to work with. So with  
this markup:















If I uncomment the second cell above, I need to be able to access the  
"next" item, something like:


final ListView rowContainer = new ListView(
"addresses", model) {
private static final long serialVersionUID = 1L;

@Override
protected void populateItem(ListItem item) {
Address a = item.getModelObject();
AddressPanel ap = new AddressPanel("address",
new CompoundPropertyModel(
new 
AddressLoadableDetachableModel(a.getId(;
item.add(ap);
/*
// DOES SUCH AN API EXIST?
//
if (item.hasNext()) {
item.next();
a = item.getModelObject();
AddressPanel ap2 = new AddressPanel("address2",
new CompoundPropertyModel(
new 
AddressLoadableDetachableModel(a.getId(;
item.add(ap2);
}
*/
}
};

My only solution currently is that I convert the list of addresses to a  
list of address tuples (pairs), so that I am able to repeat over pairs of  
addresses. In short, I am just wondering if there is a better way to do  
this rather than (pseudocode):


List addresses = myRepository.loadAddressList();
List> addressPairs = convertToPairs(addresses);
// Make the above repeater iterate over "List>"  
having access

// to two addresses per repetition

Any pointers on this? Thank you in advance.

Re: Share data in TabbedPanel

[jcgarciam]

I didn't checked the API before posting the example was using the kind of
the same code you provide earlier, just to give u a quick start :)

But the idea is to pass a model to the underlying panel on each tab, that
points to the same object reference.

Re: Ajaxifying existing application

[Igor Vaynberg]

if all your pages extend a base page then you can change the base page
to extend a panel instead.

than s/setResponsePage/setResponsePanel/

create a page that has the necessary infra to swap content panels and
wire in the new setResponsePanel to use that.

If you can create a quickstart that reproduces the problem then please
attach it to a ticket in Jira.

Re: wicket-tree checkboxes managing

[Sven Meier]

Hi,

you can utilize the usual Check/CheckGroup/CheckGroupSelector 
combination. I've added a convenience CheckContent implementation 
recently (now for Wicket 1.4 too):


  
http://code.google.com/p/wicket-tree/source/browse/branches/wicket-tree-0.4.x/wicket-tree/src/main/java/wickettree/content/CheckFolder.java


Hope this helps

Sven

Re: Share data in TabbedPanel

[jcgarciam]

Lets say you have a property in your page that point to the dataobject you
are creating and manipulating on first tab.

The model of the tabs that should see this dataobject as well can be
reference as:

tp.setDefaultModel(new PropertyModel(this,"mySharedObject"));


Being "mySharedObject" the property on you page (this) that have the object
reference that you want to shared across tabs.

Re: Ajaxifying existing application

[James Carman]

I think he meant that rather than using a page-oriented design, that
they'd need to switch to more of a one page, switch panels design?

Re: Running Wicket under WebSphere

[Clint Checketts]

I heard that Webspere gets confused with a filter as the endpoint. Try
WicketServlet. I think there also is a patch for more recent Websphere
versions.

Re: wicket-tree checkboxes managing

Hi Sven,
I'm on back on it now.
To hidden the checkboxes for roots I've put the 'if' into the
'newContentComponent' method

something like this
public Component newContentComponent(String id, final AbstractTree tree,
IModel model)
{
if (model.getObject().isRoot()) {
return new Label(id, model);
} else {
return new CheckedFolder(id, tree, model)
{ ... }

We are using WebSphere 6.1, front ended by Apache (IBM HTTP Server)

When moving our war file from our Eclipse/Jetty environment to Websphere,

WebSphere WILL find it. If anyone has any ideas how to resolve the issue,
thanks very much.
