wicket problem
hi i am facing problems in retriving the values from a multiple choice box i made in wicket frame work.I wrote a onSibmit() function but it througes an exception saying that propertymodel is set to null. Can somebody tell me how to implement this. thanks

Re: Re[2]: Alternative to Wicket data binding
Perhaps to keep us newbies happy a pointer in the javadoc to what to do if you want vanilla Java Bean behaviour might be handy. I just pulled a face and put it on my todo list to change. Anyway, I still can't decide between the verbose solution with tool support and concise magic without tool support. Will make my tech lead decide, that is what he gets the big money for :) igor.vaynberg wrote: cmon, there are plenty of things you can abuse in wicket, or any other framework. that is just the nature of the beast. as framework developers we put out features and hope that our users know how to use them responsibly. we cannot continuously cater to newbie users, we have to cater to power users as well - and that sometimes means making things that newbie users might think unclean available anyways so power users can use them easily. having two property models might work but it just adds clutter. we are going about this in circles, so what i propose is that someone who really cares about this to put out a vote. -igor On 8/28/07, Kent Tong [EMAIL PROTECTED] wrote: igor.vaynberg wrote: i really dont think this is breaking encapsulation. i will concede that there is one case where it can break encapsulation and that is when you start out with what is publically accessible and then later you change your mind and make it completely private, but forget to remap the property model. it is a case where it is easy to make the mistake of not updating property models. all other cases i believe are unimportant because you would have to go poke around the class to even know that private field is there to start with. I think the problem is that by allowing the default, core model in Wicket (PropertyModel) to access private fields, you're telling people that it is OK or even desirable to access private fields, while in fact, in your mind this power should only be exercised to *keep* encapsulation, instead of breaking it. For the moment many users don't know about this feature, so there is practically little impact on them. But once they learn about it, they will go ahead to access private fields even though the author of the class explicitly indicated that they shouldn't be accessed by not providing setters. Yes, those users can always access private fields using Java reflection. But they had to go through hops to do that. Now Wicket is telling them it is perfectly fine to do that and is making it super-easy to do. That makes a difference. Greater power comes with greater responsibility. The problem is it is easy to give people power but hard to make them realize the associated responsibility (when to use that feature). That's why I always suggest to have a PrivateFieldModel class (probably in Wicket extensions) extending PropertyModel to provide that extra power. Due to the non-default nature of PrivateFieldModel, only if one is clear about the responsibilities will he get to power. -- View this message in context: http://www.nabble.com/Alternative-to-Wicket-data-binding-tf4322899.html#a12364419 Sent from the Wicket - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] -- View this message in context: http://www.nabble.com/Alternative-to-Wicket-data-binding-tf4322899.html#a12381449 Sent from the Wicket - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

handle resource with several formats (minified, gzipped,...)
Hi,
To avoid runtime/on-the-fly compression (js minification/packing,... gzip
compression) of static resources (!= dynamic),
I do it at compile time (done via the yuicompressor-maven-plugin) and provide 3
formats (original, minified, minified+gzip)
But I need to choose the right at runtime.
if !settingsMinifiedSuffixes.isEmpty() {
foreach minifiedSuffix {
if resource with minifiedSuffix exists {
resource = resource with minifiedSuffix
}
}
}
if gzipAllowed {
if resource with gzip exists {
resource = resource with gzip
}
} else compress(resource)
setHttpHeader(gzip)
}
In your opinion where is right (simplest/best) place to implement the Resource
Selection Policy (may be later could be generalized with locale and style
selection).
1/ When resource is requested
2/ When url of the resource is build
3/ In a filter
4/ ...
optionals requirements :
* define settings at Application level (init)
* no need to patch wicket source
* applied and compatible with existing Resource's implementation
What are your suggestions ?
Regards
/David

Re: Is Wicket a proper framework for a Webshop ?
I'm in the process of slapping the developers around here, trying to get them to wake up. Senior dev's recommending struts 1 for gods sake... now that's what i call afraid of change It's out of ignorance, and their unwillingness to see what else is out there. It could also mean their unwillingness to commit their time and money on education. Do not rush with this kinds of claims. Everyone has their reasons - not everyone is lazy. If you have good enough reasons to make them move to Wicket they will probably do so. Otherwise, blame yourself for your inability to influence. Component based frameworks are not obvious. While a reasonable developer of decent experience could pick up Struts 1/2 and be efficient with it in a couple of hours. I would definitely drop Struts 1, and stick with Struts 2 as that is a different kind of animal. I am not quite sure why Eelco is being so pushy on claiming no OOP is done there, but I would really stay away from his opnions unless they are somehow Wicket directed :-) - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Ajax operations on Panels nested in Fragments
I just lost a few hours on a problem where an ajax operation on a Panel nested in a Fragment was failing as my nested panel could not find its associated markup. It seems this was because a Fragment will only reliably find its markup if you explicitly provide it with the Component that contains its markup in the Fragment constructor. If you don't, Fragment.getAssociatedMarkupStream() will find its markupProvider field is null, and so have to take a guess at where its markup might be. If your fragment usage happens to be as a direct child of the component that defines the fragment markup then it will all work out, but if you have nested it in something like a ListView then it will fail. ...So watch out kids, if you use fragments, use a constructor that tells it where its markup is. Would you like to have to guess who your real parents are? I think not. Oli - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
MarkupCache Issue
Hi All, In our aplication we are using a filter to populate the HTML base tag with the base URL.

RadioChoice and ListView
Hi all,
I'm trying to use a Radio Choice component inside a Listview so that each
list
item has one RadioGroup with three choices. When the form submit button is
pressed,
each selected choice should set a field in the model object of each list
item.
The code below should explain the problem more fully:
/*
The ultimate goal is to set the status field in each Participation object
in the participationList of the object below.
*/
public class Experiment {
private String name;
private ListParticipation participationList;
/* Other fields, constructors, getters, setters, etc */
}
public class Participation {
public static final int PARTICIPATED = 1;
public static final int NO_SHOW = -1;
public static final int SHOWED = 0;
private User user;
private int status;
public Participation() {
status = SHOWED; // Default value
}
/* getters, setters, etc */
}
/* This is the web page that is supposed to do the setting*/
public class ParticipationPage extends BasePage {
private static final long serialVersionUID = 1L;
@SpringBean
private ExperimentDAO exDAO;
private DetachableExperimentModel exModel;
public ParticipationPage(Experiment ex) {
exModel = new DetachableExperimentModel(ex, exDAO);

exModel.detach();
}
class ParticipationForm extends Form {
public ParticipationForm(String id) {

ListParticipation participationList = exModel.getEx

RadioGroup rg = new RadioGroup(choice);
rg.add(new Radio(participated, new Model(

rg.add(new Radio(no show, new Model(
Participation.NO_SHOW)));
rg.add(new Radio(showed, new Model(

}
};
subjectListView.setReuseItems(true);

Re: RadioChoice and ListView
problem is here
RadioGroup rg = new RadioGroup(choice);
you are not setting the model for the radiogroup choice so your choices go
no where
RadioGroup rg = new RadioGroup(choice, new PropertyModel(item.getModel(),
status));
or leave it as it is and use PropertyListView instead

I was under the impression that Wicket had robust back button support? Wicket's back button support is pretty robust for normal (non-ajax) requests. The problem we have with the Ajax back button comes down to the fact that we have to synchronize client with server state in such a fashion that it also keeps working with normal requests. GWT is all client side and thus doesn't have that problem. It's *Ajax* back button support is better, though it's not very automatic from what I've seen, and I wonder how it survives leaving a single page approach. We haven't given up on better Ajax back button support for Wicket though. See https://issues.apache.org/jira/browse/WICKET-271. Contributions are welcome as always.

Thanks Gabor. I had the same idea. I'll try it soon and leave here a message how it works. Btw I think many people would appreciate an article about wicket application architecture.

Or to get bookmarkable pages, keep it in the PageParameters. Except for the variables which truly belong to the session, like logged in user, of course.

wantOnSelectionChangedNotifications causing table redraw
I have a DataTable in which I have a panel which contains a textfield and a
radiogroup. When the user changes the selection in the radiogroup I'd like
to populate a value in the textfield. I subclassesed RadioGroup to catch the
selectionChangedEvent
RadioGroup choice = new RadioGroup(workflowFrame_radioPanel_radioGroup,new
Model()){
protected void onSelectionChanged(java.lang.Object newSelection) {
//Figure out what is selected and set value in textfield
}
protected boolean wantOnSelectionChangedNotifications() {
return true;
}
};
As soon as I override the wantOnSelectionChangedNotifications method I get
the notifications but the table is redrawn as soon as the user selects an
option in the radiogroup while if I do not override this method the UI does
not do this ugly redraw when the user toggles the selection in the
radiogroup. I am using AJAX to redraw my table in other instances so that
the table redraw is smooth. Is there any way I can catch the selection
changed event and have the table not redraw? I can redraw it myself with an
AJAX target after I set the value in the textfield.

Re: RadioChoice and ListView
I'm sorry to spam the list like this, but I really need help on this. Igor's
solution doesn't seem to change anything. No information is transferred to

anyone have any ideas on how I could debug this? Is there some way I can

I can see what their values are?

Re: best practice for a header component with links defined by the page
You should use panels for this. You can have panels for 1 link, 2 links a 3 links. Or even put a repeater into panel to generate as many links as you want.

Re: best practice for a header component with links defined by the page
So let me try to rephrase your problem: you have a header component that shows a variable number of components (links). Use a repeater (e.g. list view or repeating view) for the variable number of components, and you probably want to wrap the header component in a panel so that it is easy to move it around, place it on other pages, etc. Think a bit about whether those links should be internal or to bookmarkable pages, and that should do the trick, right?

Wicket capability for LARGE forms

setEnabled(false) on FocusableTextField breaks persistence
I posted this on the Databinder forum but no one seems to know of a
work-around so I thought I'd post it here.
Essentially I have a FocusableTextField that gets set by a DropDownChoice.
If the choice is not other then I setEnabled to false and I place the
string value of the DropDownChoice into the FocusableTextField. However the
model is not persisted when setEnabled is false.
Here is the code:
// list of existing emailAddresses
final List emailTypeList =
Arrays.asList(EmailAddress.Type.values());
final ListView emailAddresses = new
PropertyListView(emailAddresses) {
@Override
protected void populateItem(final ListItem item) {
final EmailAddress email = (EmailAddress)
item.getModelObject();
final FocusableTextField emailLabel = new
FocusableTextField(label, page);
if (email.getType() != EmailAddress.Type.OTHER)
emailLabel.setEnabled(false);
item.add(emailLabel);
item.add(new DropDownChoice(type, emailTypeList) {
@Override
protected boolean
wantOnSelectionChangedNotifications() {
return true;
}
@Override
protected void onSelectionChanged(final Object
newSelection) {
if (newSelection == EmailAddress.Type.OTHER) {
emailLabel.setEnabled(true);
emailLabel.requestFocus();
} else {
emailLabel.setModelValue(newSelection.toString());
emailLabel.setEnabled(false);
}
}
});
snip
In this email example the dropdown choices are home, work, and other.
If user selects home or work I want the value of the FocusableTextField to
be home or work and I do not want the user to be able to edit the field.
That's why I set the field's isEnabled to false. On the other hand, if the
user selects other, then I set isEnabled to true so that the user can edit
the field. This works properly (persists the value) because isEnabled is
true.
Is there a workaround for this problem or can someone recommend a different
approach?

VisitChildren bottom-up
Hi all,
I've writing a very heavily javascripted app in wicket and finding wicket
handles the complexity wonderfully. I've used VisitChildren(IVisitor)
successfully in numerous places but have a problem with a case where I'd
like to use it 'backwards'. I'm writing some base components which will be
used by our application programmers and our base Panel has an onClose()
method which will contribute javascript to a closing panel (rendered on
AjaxRequestTarget.prependJavascript()) What I would like to do is have a
closing panel's children automatically call onClose().
So I started with:
protected final void close()
{
visitChildren(JumbuckPanel.class, new IVisitor()
{
public Object component(Component c)
{
((JumbuckPanel)c).onClose();
return IVisitor.CONTINUE_TRAVERSAL;
}
});
}
Then I realized that this had a problem - being onClose() I needed the
children to be traversed from the bottom-up, whereas visitChildren always
seem to go top-down. That is, from looking at VisitChildren() in
MarkupContainer, it goes..
-visit this node
-if this is a container, visitchildren recursively.
wherease I need:
-if this is a container, visitchildren recursively
-visit this node.
So originally I tried to write reverseVisitChildren() in my sublcass of
MarkupContainer but then realized all of the access functions (children_size
and children_next) are private in markupContainer and my recursive call to
reverseVisitChildren would only work on my custom panel, not generic
MarkupContainers, if that makes.
Is anyone able to suggest a simple solution to this problem, as right now
the best solution I can think of is to add that functionality to
MarkupContainer as I think it might prove useful for other people at some
stage also.
Thanks,
Dean

Re: setEnabled(false) on FocusableTextField breaks persistence
the entire point of disabling the component is that you do not want it to
process submitted input and update its model. you are looking for readonly
behavior rather then disabled i think. why not just set the readonly

Re: VisitChildren bottom-up
hrm. i have implemented a postorder traversal for formcomponents (see
FormComponent.visitFormComponentsPostOrder) so you can either take that code
and use it in your app, or we can bring it up to markupcontainer and
generalize it.
the problem is that we already have visitComponents, and having a
visitComponentsPostOrder next to it seems a little inconsistent. what do
other devs think?

Re: TreeTable...how to refect a label change on TreeNode
After further evaluating what I need done...I don't believe I need AJAX. The Tree Node needs to be updated to reflect a data change, i.e. name. However, the name change occurs in a page...not in the same page as the tree. Am I correct in this...no AJAX is needed since I am changing Pages? If this is correct (no AJAX)...how to tell the nodes in the TreeTable to update/reload their information? -- View this message in context: http://www.nabble.com/TreeTable...how-to-refect-a-label-change-on-TreeNode-tf4300479.html#a12400148 Sent from the Wicket - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: VisitChildren bottom-up
Thanks for the quick reply Igor. For now I'm just going to take your
FormComponent visitor example and adapt that to my case since it looks tidy
and straightforward. It would be nice if this functionality could somehow
find its way into markupcontainer though.
Cheers,

Hi all,
I've writing a very heavily javascripted app in wicket and finding wicket
handles the complexity wonderfully. I've used VisitChildren(IVisitor)
successfully in numerous places but have a problem with a case where I'd

be
used by our application programmers and our base Panel has an onClose()
method which will contribute javascript to a closing panel (rendered on
AjaxRequestTarget.prependJavascript()) What I would like to do is have a
closing panel's children automatically call onClose().
So I started with:
protected final void close()
{
visitChildren(JumbuckPanel.class, new IVisitor()
{
public Object component(Component c)
{
((JumbuckPanel)c).onClose();
return IVisitor.CONTINUE_TRAVERSAL;
}
});
}
Then I realized that this had a problem - being onClose() I needed the
children to be traversed from the bottom-up, whereas visitChildren always
seem to go top-down. That is, from looking at VisitChildren() in
MarkupContainer, it goes..
-visit this node
-if this is a container, visitchildren recursively.
wherease I need:
-if this is a container, visitchildren recursively
-visit this node.
So originally I tried to write reverseVisitChildren() in my sublcass of
MarkupContainer but then realized all of the access functions
(children_size
and children_next) are private in markupContainer and my recursive call
to
reverseVisitChildren would only work on my custom panel, not generic
MarkupContainers, if that makes.
Is anyone able to suggest a simple solution to this problem, as right now
the best solution I can think of is to add that functionality to
MarkupContainer as I think it might prove useful for other people at some
stage also.
Thanks,

Re: setEnabled(false) on FocusableTextField breaks persistence
So it sounds like I would use something like:
final AttributeModifier ro = new AttributeModifier(readonly, true, new
Model(readonly));
if (email.getType() != EmailAddress.Type.OTHER)
emailLabel.add(ro);
If so, then the question becomes, how would I remove that attribute or reset
emailLabel to editable?

Essentially I have a FocusableTextField that gets set by a

If the choice is not other then I setEnabled to false and I place the
string value of the DropDownChoice into the FocusableTextField. However
the
model is not persisted when setEnabled is false.
Here is the code:
// list of existing emailAddresses
final List emailTypeList =

final EmailAddress email = (EmailAddress)

emailLabel.setEnabled(false);
item.add(emailLabel);
item.add(new DropDownChoice(type, emailTypeList) {

{
emailLabel.setEnabled(true);
emailLabel.requestFocus();
} else {
emailLabel.setModelValue(newSelection.toString());
emailLabel.setEnabled(false);
}
}
});
snip
In this email example the dropdown choices are home, work, and
other.
If user selects home or work I want the value of the FocusableTextField
to
be home or work and I do not want the user to be able to edit the field.
That's why I set the field's isEnabled to false. On the other hand, if
the
user selects other, then I set isEnabled to true so that the user can
edit
the field. This works properly (persists the value) because isEnabled is
true.
Is there a workaround for this problem or can someone recommend a
different
approach?

create a dynamic model instead of new Model(readonly)

Re: setEnabled(false) on FocusableTextField breaks persistence
I know how to add the attribute, I just don't know how to later remove it once added. Like I said, override isEnabled in your attribute modifier. When that returns false, the attribute won't be added. For normal requests, where a page is rendered everytime again, it simply doesn't show up. For ajax request, you'll have to add to the ajaxrequest for re-rendering and the attribute should disappear as well.

Re: setEnabled(false) on FocusableTextField breaks persistence
I don't understand. Are you saying that I should use setEnabled(false) or are you saying that I should use: final AttributeModifier rof = new AttributeModifier(readonly, false, new Model(readonly)); Either way this doesn't seem to work. - JA Eelco Hillenius wrote: I know how to add the attribute, I just don't know how to later remove it once added.

I don't understand. Are you saying that I should use setEnabled(false) or
are you saying that I should use:
final AttributeModifier rof = new AttributeModifier(readonly, false, new
Model(readonly));
new AttributeModifier(readonly, true, new Model(readonly) {
public boolean isEnabled(Component c) {
return shouldTheAttributeBeAdded();

}
and don't add the attribute in your markup.
