Re: [Wicket-user] error(...) No page found for component
yeah, your patch would work, but i think we agree that the
session approach is better and cleaner (both functionally and
conceptually) for the long term even if it could at least
/conceivably/ break some especially odd code (which it
seems likely does not even exist).
the semantics are actually quite nice in the session version.
messages added directly to the session would still have a
null reporter and persist until rendered, as they currently
do (no changes there).
messages reported by components would all be cleared at
the end of a request (not the beginning of the next one).
this is conceptually clearer and simpler and it actually
reduces memory load (as does the removal of all aspects
of feedback message storage from Page).
so i can't actually see any important disadvantage to the
session approach. and there seem to be several nice
little wins. probably less code too.

I think I'm fine with a session based solution. The thing that
wouldn't work anymore is when you assign messages to components/ pages
which are not rendered this request but a next request. That might be
too far-fetched to support though. However, the solution which I'll
post as a patch on the end of this message will support anything it
does now. The thing I like about putting them in the session is that
it is clean and will save a little bit of memory in the page. WDYT?

Do feedbackmessages in the session really need to be synchronized with CopyOnWriteArrayList? I'm in doubt whether synchronization helps that much, but if it does, wouldn't it be more efficient to use a normal synchronized one?

i am not so sure this is correct. we often deal with two page instances inside the same request - the current one and the response page. this breaks any kind of scoping as errors reported against current page will now make it into response page? dont know how likely the above usecase is, but probably more likely then having to report errors at component construction. -igor On 3/31/07, Jonathan Locke <[EMAIL PROTECTED]> wrote: yeah, threadlocal would work. it would also get rid of the need for Session feedback messages. in some sense, i think the error is really being registered for the request (thread) anyway, not any object. so i like that idea. it can just be a threadlocal in the appropriate class and everyone's happy, we actually remove code and component stays the same size. +1 Eelco Hillenius wrote: > >> Apparently the usecase is pretty rare (only discovered after 2 years of >> production use) > > Well, you can't really know as you don't know how many people ever > bumped across this and decided to implement a workaround without > mentioning it to us.

> Apparently the usecase is pretty rare (only discovered after 2 years of > production use) Well, you can't really know as you don't know how many people ever bumped across this and decided to implement a workaround without mentioning it to us. More importantly, I just don't think it is right users cannot do this, and there's a ton of ways to solve this. I agree with your queue idea, that's the nicest one. Eelco - Take Surveys. Earn Cash.

Re: [Wicket-user] error(...) No page found for component
Sure, sounds good. Can you make a proposal please? It's kind of where
we started in the first versions, but then again, much was different
and this time that can work.

Re: [Wicket-user] error(...) No page found for component
I don't like the addition of the 4 bytes to the component. Apparently
the usecase is pretty rare (only discovered after 2 years of
production use), and this will increase memory usage considerably for
a small benefit.
Isn't a message queue that isn't bound to a component but to the
current thread, that registers the object that receives the feedback,
and is queried at the end of the request to store any messages at the
appropriate place?

Re: [Wicket-user] Get versionManager null error after upgrading the wicket to the current snapshot.
Is it the latest svn version? There have been several important
versioning fixes lately, i suggest you checking the latest from svn.

Re: [Wicket-user] error(...) No page found for component
Why don't we fix this how? Errors are stored in page. In component
constructor you don't know the page. What could work would be a
temporary array in component that would be copied to page in onattach,
but i don't really this is a common usecase.
If you need to add errors, just do it in onAttach.

but when i open it again , it will generate the bellow error. i searched the
form ,and find someone also happen the same error.
final DefaultDataTable table = new DefaultDataTable(listContainer, "dataList",
columns, dataProvider, 15);
table.setOutputMarkupId(true);
final ModalWindow modal1 = new ModalWindow(this, "modal_add");
modal1.setPageMapName("modal_add-1");
modal1.setPageCreator(new ModalWindow.PageCreator()
{
public Page createPage()
{
return new EditFilterWordPage(getPage(), "");
}
});
modal1.setWindowClosedCallback(new ModalWindow.WindowClosedCallback()
{
public void onClose(final AjaxRequestTarget target)
{
target.addComponent(table);
}
});
modal1.setCloseButtonCallback(new ModalWindow.CloseButtonCallback()
{
public boolean onCloseButtonClicked(final AjaxRequestTarget target)
{
target.addComponent(table);
return true;
}
});
new AjaxLink(this, "createRecord") {
public void onClick(AjaxRequestTarget target) {
modal1.show(target);
}
};

wicket 2.0 has been discontinued for various reasons. you might want to
switch your project to the 1.x branch.
new DropDownChoice(form, "profile",
profileManager.getProfiles(getProfile()),
thats all you need - ie dont specify the model. that way ddc will use the
compound property model you have and put its selection into the "profile"
property for you.
also notice that profilemanager.getprofiles(getprofile()) should be new
LoadableDetachableModel() { load() { return profilemanager.getprofiles...

Re: [Wicket-user] error(...) No page found for component
You component is not attached to a parent yet.
You could try doing that work in onAttach().

[Wicket-user] How do you update domain object from Model/DropDownChoice
I'm a divorced Struts programmer the breakup took place when I found
Wicket. So I'm new to Wicket and I have a question about
Model/DropDownChoice/Domain Object updating.
Sorry about the long email.
Here is my question:
How do I update the Buyer object with a different Profile object if the
user selected a different Profile object on the form. I tried the
onSelectionChanged in the DropDownChoice component and that worked but I
would have to hit the submit button twice and that didn't feel right.
So what is the most correct way to do this with in wicket?
My environment is:
Java 1.5
Wicket 2.0-SNAPSHOT
Wicket-Spring 2.0-SNAPSHOT
Hibernate 3.2.1-GA
Spring 2.0.2
Here is my code:
public class Profile
{
private String identity;
private String name;
... setters/getters ...
}
public class Buyer
{
private String identity;
private String firstName;
private String lastName;
private Profile profile;
... setters/getters ...
}
BuyerPage.html:
Select Profile
Profile1
Profile2
Last Name
First Name
...
public class BuyerPage extends MyBasePage
{
...
public BuyerPage(PageParameters params)
{
Buyer buyer = new Buyer();
IModel buyerModel = new CompoundPropertyModel(buyer);
new FeedbackPanel(this, "feedback");
identity = params.getString("identity");
if( identity != null )
{
buyer.setIdentity(identity);
buyer = buyerManager.findByIdentity(buyer);
if( buyer != null )
{
buyerModel = new CompoundPropertyModel(buyer);
}
}
else
{
isNew = true;
buyer.setProfile(getProfile());
}
initializeForm(buyerModel);
}
protected void initializeForm(IModel buyerModel)
{
BuyerForm form = new BuyerForm(this, "buyerForm", buyerModel);
TextField lastName = new TextField(form,
"contact.lastName");
lastName.setRequired(true);
TextField firstName = new TextField(form,
"contact.firstName");
firstName.setRequired(true);
... other components ...
Profile profile = buyerModel.getObject().getProfile();
new DropDownChoice(form, "profile", new
Model(profile), profileManager.getProfiles(getProfile()),
new IChoiceRenderer() {
public Object getDisplayValue(Profile profile)
{
return profile.getName();
}
public String getIdValue(Profile profile, int i)
{
return profile.getIdentity();
}
})
}
class BuyerForm extends Form
{
public BuyerForm(MarkupContainer markupContainer, String s,
IModel buyerModel)
{
super(markupContainer, s, buyerModel);
}
public void onSubmit()
{
buyerManager.save( getModelObject() );
setResponsePage(BuyerListPage.class);
}
}
}
TIA,

[Wicket-user] error(...) No page found for component
Hi.
I have a problem in that inside the constructor of a page(panel actually) i
invoke a stored procedure which needs to get the model for the panel. The
stored procedure may throw an error message. The error message should be
seen by the user, he can understand what he did wrong. So inside the
constructor i have something like this:
public PanelConstructor() {
try {
} catch(UserPresentableException e) {
error(e.getMessage);
}
}
The problem is that if the error is thrown i get a No page found for
component. I understand that the cause of the error is that the "error
component" not being instantiated because of the constructor not being
finished(or i think that's the cause).
Any ideas of solutions that i can implement?
I know that i could set wicket to production instead of development and get
rid of the stack trace. The problem is that i would like to keep the error
message - to show the error message back to the user-. Should i instead of
doing error(e.getMessage) rethrow the message inside a new defined exception
and have a custom error page for that exception in which i would show only
the message of the error.
Is there any option that would keep me from treating the errors in the
constructor other than how i treat an error from a button push?
Thanks.

Re: [Wicket-user] complex user case
looks not very complex - base would be the "Autocomplete Example" http://www.wicket-library.com/wicket-examples/ajax -> Auto Complete... rest is a bit CSS playing + Contentvalidating - only the point with the keystroke would need add. ajax and seems odd to me as i dont know a secure way to capture keyboard input - as this is not valid for JS to bind a command to a window (afaik), but i also dont see the reason you need this...

The application requires a richish user interface (don't they all now!) The 'richest' user case is 1) The user starts entering the name of a client into a text field. 2) After entering a few letters they enter a special keystroke. This results in a server side call looking for clients with that name. 3) If only one client is found, then the clients name is entered into the text field and the focus moves onto the next text field. 4) If more than one client is found, then a pop up is displayed to user. This pop up contains the search results as well as extra controls so that the user can further narrow his search. This could either be a multi page table with ordering and filtering, or a 'google type' search result. By selecting one of the items, the pop up is closed and the client name is entered into the text field and the focus moves to the next control. Can Wicket be used to implement the user case?

Re: [Wicket-user] complex user case
What comes close is Wicket's autocompletion field. It works just like google's autocompletion. It is quite flexible and easy to use.
