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.

I know how to add the attribute, I just don't know how to later remove it

Problem with that though, is that it would always add the readonly
attribute. If I remember correctly, the actual value doesn't matter
much.

Always add the attribute modifier, override isEnabled and let that
return true if you want to add the attribute, and false if you don't.

Re: VisitChildren bottom-up
Just a quick think on how to fix with minimal impact on MarkupContainer, I
wonder if it would be possible to do something like the following:
public interface IPostVisitor extends IVisitor
{
public Object postComponent(component C);
}
then in MarkupContainer.visitChildren() after the recursive visitChildren()
call do something like:
if (visitor instanceof IPostVisitor)
{
if (clazz == null || clazz.isInstance(child))
{
// Call visitor
value = ((IPostVisitor)visitor).postComponent(child);
...
Or something like that, just thinking out loud a bit...

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?

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.

Re: RadioChoice and ListView
This looks wrong too:
List participationList = exModel.getEx
().getParticipationList();
ListView subjectListView = new ListView("list",
participationList) {
if your experiment model is intended to be a detachable one, ie. if you are
loading it from a database or something, then you shouldn't instantiate the
listview with a list but with a model that loads that list (or delegates to
another model that eventually loads the entity to which the collection
belongs...). If you pass the plain collection you are defeating the entire
purpose of having the loadabledetachablemodel in the first place. For
example, use new ListView("list",
new PropertyModel(exModel, "participationList"));

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]
Example of pseudo-ajax file uploading using iframes
Hi all, here is a hopefully functional example showing how to use an iframe to upload a file and afterwards call a behavior on a component belonging to the top frame, so that an ajax action could be carried on in consequence (maybe to get rid of the iframe, or to show an informative message, or whatever). This is along the same venue as other examples that are around the web, like http://www.air4web.com/files/upload/. I don't have the time to write a proper wiki page just right now, so I simply attach the example here. Hope it helps.

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: 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
attribute on that field.

Re: Wicket capability for LARGE forms
yeah, with ajax instead of simply disabling them you can remove them completely, or replace them with something else entirely. however, if all you really want to do is to make them disabled on clientside that should work also. might not be as straight forward but should work. -igor On 8/29/07, Antony Stubbs <[EMAIL PROTECTED]> wrote: > > > Ah yes, DataTable, I see, like a data grid... > And what about changing the fields to enabled / disabled?

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

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);
}
}
});
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?

Re: Updating Panels with AjaxLazyLoadingPanel
Why not just use the AjaxLazyLoadingPanel? I'm currently using it and my lazy loaded component is updated via AJAX. So, page comes up, ALLP loads the report panel which can take a few seconds. Then I have an AJAX submitted form that updates the filters for the report and refreshes that table using (from memory IndicatingAjaxSubmitButton) so while the report panel itself doesn't get the spinner on the update, the button gets that indicator showing that things are working.

Re: Wicket capability for LARGE forms
Ah yes, DataTable, I see, like a data grid... And what about changing the fields to enabled / disabled?

That's one way to do it. But a better way typically is to build up your pages dynamically, using panels for content that can change. Or a combination of the two.

Re: best practice for a header component with links defined by the page
Igor, sorry if I've irritated you. I know some of my frustration comes from A. an ugly reluctance to embrace change and B. Wicket is doing great things but it's somewhat early days, and the documentation (tutorial books and recipe collections) is still scanty. Eelco, thanks, your summary was accurate. I thought about a repeater, it seemed like overkill, and I thought maybe there was a "third way". (I still have to look into how the encompassing page would feed the links into the component, maybe not that difficult) So am I correct in thinking that, in general, most HTML pages in WIcket will have all possible subcomponents listed, and the visibility will control things that shouldn't be there...

Best way to add a MarkupFilter
What's the best way to add a markup filter to my app? I noticed that in the settings I can override the MarkupParserFactory and provide my own filter, but that is not what I want to do. I just want to use the default factory, but add my own filter. Thanks! - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Yeah, you definitively should not just add all these examples by hand :) What you do is e.g. use a DataTable component. The data provider would return the rows, and you define the columns on that data table. Rest should be straightforward. Don't forget to set the itemReuseStrategy if you're working inside a form (e.g. to use ReuseIfModelsEqual).

Apparently there is a javascript library that allows you to do just this. http://jroller.com/wireframe/entry/auto_previewable_wicket_pages I'm wondering why such a tool is not part of wicket? I will give it a try. Thank you all for your help.

Wicket capability for LARGE forms
I have a couple of pages with _very large forms_, that are also modified dynamically to set which fields are editable using javascript, dependant on the value of a drop down list. Please see the example image attached. And that's only the first page the application is in - *gasp* - struts. I love what I've seen so far with Wicket, but I'm unsure what it's like to use compared to say, Stripes, Struts 2, Click, Tapestry etc when it comes to very large forms. being that setting up each field in wicket is kinda verbose... What are people's experiences? How do you find Wicket to use in very large forms? Thoughts? Ideas? Alternatives?

Re: RadioChoice and ListView
break in your onsubmit and look at the list that the listview is pointing
to. make sure the data is there, the fact that it isnt being persisted might
be a problem outside of wicket's scope.

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?

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. And you then need only one placeholder on the page (for the panel). -Matej On 8/29/07, Kirk Israel <[EMAIL PROTECTED]> wrote: > > Hey there-- > So I came up with a solution to this, but I suspect it's not very > Wicket-y, so I'd like some suggestions on best practices: > > We want a header component that can go on different pages, with 1 2 or > 3 links to other pages. > (Well, I guess ideally any #, but with my approach it was easier to > match it to the maximum shown in the spec).

Wicket getting some bad press at Slashdot.org
Over in the Slashdot article about "GWT in Action" there are some negative opinions toward Wicket expressed. Just thought I'd mention it in case any of the gurus want to weigh in too. (Head over to this link, set the threshold to 4, then search for "Wicket", http://books.slashdot.org/article.pl?sid=07/08/29/1418229 ). - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

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
the database upon hitting "on submit". If no one knows the solution, does
anyone have any ideas on how I could debug this? Is there some way I can
reference the selections of the radiogroups from the the onSubmit method so
I can see what their values are?

Re: Is Wicket a proper framework for a Webshop ?
GWT for a webshop? that doesnt look as a right fit to me. Also you need nice bookmarkable an crawleable urls for a webshop, that is possible just fine now in wicket (especially the new hybrid url support in 1.3) but with gwt this is not really possible, a full ajax webshop is in my eyes a contradiction..

best practice for a header component with links defined by the page
Hey there-- So I came up with a solution to this, but I suspect it's not very Wicket-y, so I'd like some suggestions on best practices: We want a header component that can go on different pages, with 1 2 or 3 links to other pages. (Well, I guess ideally any #, but with my approach it was easier to match it to the maximum shown in the spec). Visually, the end result would be Back to: _LINK1_, _LINK2_ or _LINK3_ As far as i can tell, the links and their labels should be created by the page containing the component. The trouble is, since the HTML and wicket:id for displaying each link is in the HTML for the component, the page has to "know" what ID to assign its link (and it doesn't seem like you can change the id of a component object after its created, which would have meant the page could just hand a list of un-ID'd labeled links in, and the component could have re-IDed them to match the HTML) So the component has a static callback getIdPrefixForLink() and getIdPrefixForLinkLabel(), and the page uses that, and then uses that string + 0, 1, or 2 for the links its making and handing to the constructor of the Header component. So if the Component only gets 1 Labeled Link, it then creates placeholder objects for the other 2, to make sure the hierarchy as outlined in the HTML is still ok, and then just hides them. And there's a tad more logic for the commas and the "or". So, this all seems really hacky to me. What's a better way? In other words: Is having to make place holders for everything that ever MIGHT appear on a page or component, and then making them invisible when you don't need them, the Wicket way, or is there something more direct? And/or is there a standard way of letting parent pages or component make subsubcomponents to be added to a subcomponent (e.g the Page making PageLinks to be added to the Header component -- incidentally I can't just pass in a reference to the class, because of what we had to do to make "lazy loading" links that don't fully instantiate the page they go to until that link is clicked.) - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: Why AJAX call resets the focus on the component?
you can call AjaxRequestTarget#focusComponent(Component). either you pass the AjaxRequestTarget to the replacing panel and let it set the focus itself or you can have a method which returns the component that should get the focus. gerolf On 8/29/07, Francisco Diaz Trepat - gmail <[EMAIL PROTECTED]> wrote: > > Hi, I am changing a panel inside a page with an ajax link, I > change them from one to another panels A B C D etc. > Inside each of the panels there is a field (textfield, choicefield, etc, > depending on which panel) that must have the focus when loaded. > > I previously built a behavior that can be added to any component that > needs > the focus. > That behavior function is called perfectly but before the pos-handlers for > the ajax call end. > So what happens is that the ajax functions are putting the focus on the > component that had it before the call started, in this case the ajax link. > > And what is happening due to that call is that my component gets the > focus, > but immediately after gets blur or the focus is taken away from the field > and back to the link. > > > Is there another way? or a form to avoid refocusing of components in ajax > calls? > > > f(t) >

Hi, I use DatePicker with DateTextField. Date form the DateTextField is bound to an object with PropertyModel. I want that user can choose no date. I put there an AjaxLink which will set null in model object and repaint DateTextField. But when I use this link DatePicker doesn't work anymore. I opens the calendar but if i choose something it does not appear in the DateTextField. What only helps is to go on other page and then come back. What i am doing wrong?

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.

Why AJAX call resets the focus on the component?
Hi, I am changing a panel inside a page with an ajax link, I change them from one to another panels A B C D etc. Inside each of the panels there is a field (textfield, choicefield, etc, depending on which panel) that must have the focus when loaded. I previously built a behavior that can be added to any component that needs the focus. That behavior function is called perfectly but before the pos-handlers for the ajax call end. So what happens is that the ajax functions are putting the focus on the component that had it before the call started, in this case the ajax link. And what is happening due to that call is that my component gets the focus, but immediately after gets blur or the focus is taken away from the field and back to the link. Is there another way? or a form to avoid refocusing of components in ajax calls? f(t)

I'm new to wicket and have a very simple question: Got a usual html template for all my pages: HEADER ... page content ... FOOTER Inside my span elements for header and footer I have actual markup and this allows me to see a full page with headers and footers by just opening the html in a browser. The markup gets replaced by wicket once the page is rendered via a web server. Obviously I don't want to replicate the markup inside my span elements to all my other 100s of pages but I do want to be able to open all the other pages in a browser and see the header and footer. Is this possible perhaps with some wicket tool?
Re: RadioChoice and ListView
Thank you for the quick reply, but this fix doesn't seem to work. The
selections are never persisted on form submit. Any ideas?

Re: Updating Panels with AjaxLazyLoadingPanel
my understanding is that AjaxLazyLoadingPanel is most useful when you have a component that is very costly on the serverside (e.g. loading a big pile of data from the database or doing some crazy calculations, ...). so instead of having to wait for that single component to finish processing, you add the lightweight AjaxLazyLoadingPanel to the page. as soon as the page is rendered, the ALLP lazily loads the heavyweight component via ajax. this obviously leads to faster inital page loading. although you could also load an ALLP via ajax (which in turn loads the heavyweight component), but that needs an additional ajax-roundtrip. but there could still be a valid usecase for that... so basically, if you just want to load a component via ajax and want the little wheel, you could take a look at (AjaxIndicating)[Fallback](Link|Button) which automatically render the little wheel during an ajax request. puh, enough for now ;) please let me know if i got something wrong... hth, gerolf On 8/29/07, Francisco Diaz Trepat - gmail <[EMAIL PROTECTED]> wrote: > > Hi list, I have a simple site with a menu on the left and a content in the > center that needs some wicket magic. ;-) > > Instead of reloading the page from menu link to menu link, I would like to > have AjaxLinks and a kind of AjaxLazyLoadingPanel that could change by > each > click without reloading all pages. > > Thankfully one big part is done.

Re: Hibernate/Spring transaction problem
I dont know anything about Spring Hibernate template. But I use a class
HibernateUtil from book Manning: Hibernate in Action (or Java perzistnce
with Hibernate, it is a 2nd edition of first book) and it works super. I
have only one SessionFactory in JVM, and only one Session and Transaction in
every thread. U can look for it.

Take for instance Hmmm... I didn't quite finish that sentence. Basically, I mean arguments like how many hits on job search sites it has, whether it is backed by big vendors, how many component libraries and tools there are for them (regardless of the fact the quality of them and whether that is a good thing in the first place), etc. Arguments that may have some merit in them, but I hate to see those managerial arguments prevail in technical discussions so often.

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.

You can pile on the functionality without the code becoming a nightmare, and reusing components is even easier when no one is obsessing over appearance. Even on the front end, checkout is a multistep process that I would hate to code without managed state.

Don't think Struts is obvious to many people, even if you can learn it in a few hours. > I am not quite sure why Eelco is being so pushy on claiming no OOP is > done there Well, sorry for having an opinion. Model 2 frameworks encourage procedural programming. I'll repeat that a thousand times if you like. 'Actions' are not stateful, and their abstraction level matches the request/ response cycle, not anything more granular. If you're coding with model 2 frameworks, you are basically receiving a request, interpreting the parameters sent with that request, preparing the data for use in the view - which you in fact do globally for that template! - and finally requesting the framework to render a template. Now in contrast, applying OOP means that you can create abstractions that combine data (stateful) and behavior (scoped on the class, not the request/ response cycle) and that you can properly apply data hiding (link A doesn't have to have knowledge of link B/ rest of the page to function). > but I would really stay away from his opnions unless > they are somehow Wicket directed :-) Wow.

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 List 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);
add(new ParticipationForm("form"));
exModel.detach();
}
class ParticipationForm extends Form {
public ParticipationForm(String id) {
super(id);
List participationList = exModel.getEx
().getParticipationList();
ListView subjectListView = new ListView("list",
participationList) {
private static final long serialVersionUID = 1L;
/*
I imagine the correct code should be something like
this...?
*/
public void populateItem(final ListItem item) {
Participation participation =
(Participation)item.getModelObject();
item.add(new Label("name", participation.getUser
().getName()));
RadioGroup rg = new RadioGroup("choice");
rg.add(new Radio("participated", new Model(
Participation.PARTICIPATED)));
rg.add(new Radio("no show", new Model(
Participation.NO_SHOW)));
rg.add(new Radio("showed", new Model(
Participation.SHOWED)));
item.add(rg);
}
};
subjectListView.setReuseItems(true);
add(subjectListView);
}
@Override
protected void onSubmit() {
/*
* Somehow I have to set each Participation object in the user's
participationList
* to the choice from corresponding the radio group.
*/
exDAO.persistExperiment(exModel.getEx());
exModel.detach();
}
}
}
Does anyone know how to do this easily? I imagine it's not difficult, I just
can't figure it out
from the examples on the web.
Thanks!

Updating Panels with AjaxLazyLoadingPanel
Hi list, I have a simple site with a menu on the left and a content in the center that needs some wicket magic. ;-) Instead of reloading the page from menu link to menu link, I would like to have AjaxLinks and a kind of AjaxLazyLoadingPanel that could change by each click without reloading all pages. Thankfully one big part is done. All pages basically creates a new panel instance that holds its contents, so I already have every panel developed. I just need to load them into the main page by ajax means and if it is possible, have the little wheel from the AjaxLazyLoadingPanel. f(t)
Re: MarkupCache Issue
wicket caches markup, that is needed. so what you should do is add a component in your basepage that outputs the base tag. -igor On 8/29/07, Kumarasun Nadar1 <[EMAIL PROTECTED]> wrote: > > Hi All, > > In our aplication we are using a filter to populate the HTML tag > with the base URL. > But since the markupcache caches the page markup the base tag is getting > populated incorrectly for 2 different users using different hostnames. > > Is there a way wherein we can tell wicket not to cache the base tag and > populate it for each request. > > > Thanks > kumar >
MarkupCache Issue
Hi All, In our aplication we are using a filter to populate the HTML tag with the base URL. But since the markupcache caches the page markup the base tag is getting populated incorrectly for 2 different users using different hostnames. Is there a way wherein we can tell wicket not to cache the base tag and populate it for each request. Thanks kumar
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]

Re: DataTable with DropDownChoice to set rowsPerPage
Ok, got it working, thanks to igor. Here is the code for Wicket version
1.2.3 that dynamically updates the rowsPerPage for a given DataTable:
List rows = Arrays.asList(new String[] {"5", "10", "15", "20"});
add(new DropDownChoice("rows", new IModel() {
public void setObject(Component component, Object e) {
Integer rows = Integer.parseInt((String) e);
contacts.setRowsPerPage(rows);
}
public Object getObject(Component component) {return
contacts.getRowsPerPage();}
public void detach(){}
public IModel getNestedModel() {return null;}
}, rows) {
@Override
protected boolean wantOnSelectionChangedNotifications() {
return true;
}
});

Re: Hibernate/Spring transaction problem
Have you the same problem using directly the Hibernate session?
It's also interesting to read this article about the Hibernate template:
http://blog.interface21.com/main/2007/06/26/so-should-you-still-use-springs-hibernatetemplate-andor-jpatemplate/
I remember I had in the past similar porblems with the hibernate
template... actually I didn't understand the problems I was
experiencing but after having red the article I tried to use directly
the session and it worked.
My code now looks in this way:
public Account saveOrUpdate(Account account) {
account.setDateModified(new Date());
getSession().saveOrUpdate(account);
//Maybe flush and refresh can be avoided...
getSession().flush();
getSession().refresh(account);
return (Account) account;
}
Hope this helps.
Ciao,

Other factory methods exist to provide choice for these attributes. But while you are in there adapting it to 2.3.0, by all means feel free to make whatever adjustments you want. You might even want to start with a clean slate, since the work YuiHeaderContributor was set up to do has been made redundant with the addition of the dynamic loader. best, jim - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Testing AbstractAjaxTimerBehavior with WicketTester, executeBehavior???
Ok this is becoming a habit answering my own questions but I've just worked
it out, please let me know if there is a more elegant solution:
tester.assertComponent("resendLabel", Label.class);
tester.assertLabel("resendLabel", "in 20 seconds");
tester.executeBehavior((AbstractAjaxBehavior)tester.getLastRenderedPage().getBehaviors().get(0));
tester.executeBehavior
((AbstractAjaxBehavior)tester.getLastRenderedPage().getBehaviors().get(0));
Label resendLabel = (Label)tester.getLastRenderedPage().get("resendLabel");
assertEquals("Resend label has not updated", "in 19 seconds",
resendLabel.getModel().toString());
Hope that helps some noob like me.

Hibernate/Spring transaction problem
i have a button on a form, when clicked it saves a object to the database (via Spring's HibernateTemplate), but for some reason when i look in the db it is not there, until i go to another page, then suddenly the object is being written into the database. i am presuming that the session is not being flushed, until i go to another page, so i added a flush to my save method, but still experience the same behaviour. either the session or i am thinking that it might be running in a long running transaction, which only ends once a new request is coming in, and subsequently write the data to the database. any thoughts? -- pokkie -- View this message in context: http://www.nabble.com/Hibernate-Spring-transaction-problem-tf4347663.html#a12386692 Sent from the Wicket - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Testing AbstractAjaxTimerBehavior with WicketTester, executeBehavior???
Hi, Another noob question here but I'm trying to setup a test case that tests the abstract timer on my page, like the WorldClock example. I see there is the executeBehavior method in the WicketTester but I'm not entirely sure how to set this up. Basically I want to fire the timer event that I've setup on the page and check the appropriate changes have been made to the labels on the page. So for the world clock example it would mean that I would fire the event in my test then check that the time had updated in the label. Help would be much appreciated. Cheers Simon

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.

RE: Is Wicket a proper framework for a Webshop ?
Could you elaborate on what is lacking in Wicket when referring to the back button support (when compared to GWT)? I was under the impression that Wicket had robust back button support? -Original Message- From: Eelco Hillenius [mailto:[EMAIL PROTECTED] Sent: Tuesday, August 28, 2007 1:56 PM To: users@wicket.apache.org Subject: Re: Is Wicket a proper framework for a Webshop ? It sounds to me like GWT might be a better choice, especially if you need Ajax & robust back button support. Wicket is a good choice when you need a mixed approach. I don't think SpringMVC would be a better choice in any way. Eelco On 8/28/07, neekibo <[EMAIL PROTECTED]> wrote: > > Hi all Wicket-users! > > I am new to web development and so to Wicket.

Re: Is Wicket a proper framework for a Webshop ?
Thanks to all, I will analyse how complex my UI will be and than evaluate if Wicket fits in. Thanks for pointing at Stripes... I always thought: "Spring is so cool, everybody says that." So SpringMVC is the way to go, but as mentioned here it is quite low-level. My today's two favourites :=) 1. Wicket - SpringCore - Hibernate 2. Stripes - SpringCore - Hibernate Thanks for pointing at http://databinder.net/site/show/overview Databinder . I will discuss with myself if abandon Spring is an option. I guess using Spring only makes sense when you have to code quite a bit of business logic. Discussion, especially arguments against Wicket, my case in mind, are welcome :=) Paul -- View this message in context: http://www.nabble.com/Is-Wicket-a-proper-framework-for-a-Webshop---tf4341788.html#a12384390 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: No localizer has been set
thats odd
on your production machine you have enabled debugging:
if (log.isDebugEnabled())
{
log.debug("detaching " + this + " for requestCycle " +
RequestCycle.get());
}
and that code is not executed for development machine?
Thats a bit the reverse what it should be..
But the problem is that StringResourceModel.toString() calls getString()
thats wrong it shouldn't do that.

Re: Panel/Localizer issue
yes that should also be lazy through a model
can you create an jira issue ? (with a patch if possible)

Re: PasswordTextField no longer supports cookies in beta3
In a reaction to myself: I can now see why the change was valid: it is easy to allow persistence again by overloading method supportsPersistence(). Giving false is the safest default value for PasswordTextField. It should be added to the migration list though (I'll do that in a sec). Regards, Erik. Erik van Oosten wrote: Dear wicketeers, In 1.3beta3 I can no longer call new PasswordTextField(...).setPersistence(true); as this results in a: java.lang.UnsupportedOperationException: FormComponent class org.apache.wicket.markup.html.form.PasswordTextField does not support cookies I do not understand why PasswordTextField no longer allows this. Okay, it is not super safe, but it is also not very unsafe and very desirable in some circumstances. Could someone provide the rationale for the change?
