[Wicket-user] wicket legacy integration (high level suggestion)
i think it will help wicket's cause if it has some way of integrating into existing applications, especially existing pages. what can be done is to have a way for the page's markup (the html), to be a url which is then retrieved to get the html page. if this url points to struts/jsp/servlet, then those technologies will render it with what they have, and if there are wicket:id attributes, they will appear in the resulting html, which wicket can now process or, support embedding wicket generated html snippet in another page (by jsp:include). i've done some work here (and posted most of it), but there is still a strong tie with Page classes (that is, the embedded snippet needs to be a Page implementation). ittay -- === Ittay Dror Chief architect, openQRM TL, R&D, Qlusters Inc.

Re: [Wicket-user] conversion
the case here is different i think - the component has the converter - the component doesn't have the type set --> the converter is not used in convert() --> the converter *is* used when setting the object model. --> the conversion fails, but not in a nice way (because it is late in the process) Eelco Hillenius wrote: Yeah, I'm not totally crazy about that either.

Re: [Wicket-user] conversion
yes, after i saw the exception, and looked at the code to find the exact
reason, i added the type
Johan Compagner wrote:
we try to do it:
if (object instanceof String)
{
// and that String is not empty
final String string = (String)object;
if (!Strings.isEmpty(string))
{
// and there is a non-null property type for the
component
final Class propertyType = propertyType(component);
if (propertyType != null)
{
// convert the String to the right type
object =
component.getConverter().convert(string, propertyType);
}
}
}
PropertyResolver.setValue(expression, modelObject, object,
component==null ? null:component.getConverter());
But if you use a compound/propertymodel as the texfields own root model
then the component isn't there
so the Session will be used.
Why don't you se the right type on the textfields? That is the prefered
way because the error is catched much earlier
and validators can work on the right object.

which was considered unexpected, and so the page was redirected to
the error page (rather than showing a conversion error)

Re: [Wicket-user] conversion
I guess you mean "only try to convert when there is a type set" ?Checkbox is abit of a bad example, A DropDown or anohter Choice is a better oneConverter is Type conversion String to Date or Integer or what ever. But convertValue (used in the Choice classes) is not type conversionBut it is more a Lookup conversion (or how do i say this better)The input/request value is an id and for that id a object is lookupped.. The normal converter can never do that. Because it doesn't have any context (The Choices List and the IChoiceRenderer in this case)But as i said we always try to use the converter of the component.But for this particulair case we don't have the component. Maybe we should have a getRootObject(Component) and setRootObject(Component) methodsin the ICompoundModel interface, So that we can give the component to the model.johan On 5/10/06, Eelco Hillenius <[EMAIL PROTECTED]> wrote: Yeah, I'm not totally crazy about that either.

Re: [Wicket-user] What's the purpose of PackageResource.bind in IInitializer ?
It's something we probably will try to get rid of for Wicket 2.0;
instead of the pessimistic, register first approach we have now, we
can choose an optimistic approach which will allow disallow in a
similar fashion as file filters work.

Re: [Wicket-user] Visibility of clearInput method
you just want only to clear the input on that specific FormComponent?So you don't want to call Form.clearInput() ?Calling FormComponent.valid() does the same thing by the way. It clears the rawInput(and calls onValid())
But i guess this is not that logical to do (know)clearInput can be public final in my eyes.johanOn 5/9/06, Roan O'Sullivan <
[EMAIL PROTECTED]> wrote:
Could the FormComponent#clearInput() be made public?
This is my scenario:
* a recipient property on my model object
* a DropDown (that listens to selection change events) lets users select from a list of Recipient beans
* a TextField is bound to the email field for the model object's recipient property
When I select a new Recipient, the display value of the email TextField is still blank. In 1.1.1 the TextField would show the new model object value (which is the correct behavior for my page).
I assume the change in behavior with 1.2 is due to the introduction of FormComponent#rawInput (which, by the way, works like a dream in most other scenarios). The #getRawInput() method on the TextField bound to "
recipient.email" returns empty string ("") in the #onSelectionChanged() listener for the DropDown bound to recipient.
If I could invoke #clearInput() on the TextField bound to "recipient.email", I assume that model value for the newly selected recipient would get rendered just like I want it to. Are developers willing to consider API changes this late in the game for a
1.2 release?
If #clearInput() cannot (or should not) be made public, can anyone think of any other ways to achieve this effect?
Thanks, Roan
Re: [Wicket-user] What's the purpose of PackageResource.bind in IInitializer ?
also no cluster or what ever. Simple one tomcat installationThe only thing is you need to do some maintenance. So you shutdown tomcat or the webapp contextupdate it and restart it again. The shutdown did save the session to disk..
Then after restart all sessions comes in memory again. And the request comes in.But now pages are not made because the come from the session. So resources are not bound anymore.. (or yet)With an initializer that is taken care of.

Re: [Wicket-user] composite component
why this strange method: private CompositeComponent getThis() { return this; }why not CompositeComponent.this on the places where you use that.also i see a nullpointer:
public String[] getInputAsArray() {// go over all children, and create a list.final List list = null;you don't create the list.but do access it in the innerclass.
And are the children you put in that composite also again formcomponents?Why why aren't that just Check or Radio classes normal webcontainers Because you are now creating a hierchy in FormComponents?

Re: [Wicket-user] (conceptual) bug in getModelObject()?
i think the compound concept needs to be generalized.
the ICompoundModel is really IAutomaticallyInheritedModel. whether it is
compound (a model simulating holding other models) is not important i think.

I believe it's because of compound models. e.g. when you have
compound property model, getObject(Component) returns you the
property of the model object which name is sme as component id.
getObject(null) returns you the whole model object.
If you have a form for instance and set it a compoundpropertymodel,
the modelObject of the form is the object you put to the model.
but the model objects of components placed into the form are
actually properties of the object you set to the model. (as the
components will inherit the model from the form)

Re: [Wicket-user] (conceptual) bug in getModelObject()?
It is not simulation holding outer models.It is the model for every child that doesn't have a model so yes it inherits its.But that is just the name. And i can't really discuss that what the real meaning is of comound and if it is the 'good' word for that or not.
So i don't know what you mean with "generalized" because you just say it should be renamed? But from the perspective of the componentyou set it the model on i find a IAutomaticallyInheritedModel very strange. If it is inherited why do i need to set a inherited model on something?
ICompoundModel could have a getRootObject() that would be the samething as getObject(null)But remember that getObject(null) is not really only for Compounds it is also for the normal PropertyModels.They also should just return the complete object.
A normal none property model also just returns the complete object on null (the difference that it just completely don't look what the component is)It is just a contract..johan

I believe it's because of compound models. e.g. when you have compound
property model, getObject(Component) returns you the property of the
model object which name is sme as component id.
getObject(null) returns you the whole model object.
If you have a form for instance and set it a compoundpropertymodel, the
modelObject of the form is the object you put to the model.
but the model objects of components placed into the form are actually
properties of the object you set to the model. (as the components will
inherit the model from the form)

RE: [Wicket-user] ListChoice changes appearance from dropdown to listbox
Hi Johan
Yeah it must be something
like that. But there are multiple rows for this case. I do also have a
properties files where the default text are in, im not sure if that has any
impact.
Somehow it must have
slipped my mind that there where the dropdownchoice I guess I’ll just use
that instead since it’s the correct one to use.

ListChoice changes appearance from dropdown to listbox
A ListChoice should
always be a List instead of a DropDown (for a drop down we have the
DropDownChoice)
I don't know why you see a difference it shouldn't look at all to the model
that holds the selection.
It only looks at the choices:
tag.put("size", Math.min(maxRows, getChoices().size()));
so i guess if maxRows of size() == 1 then it becomes a dropdown?

Hi
Im not sure if this is the intended functionality, but I belive I've
discovered an oddity or featureJ
.
When I use the constructor which also takes a model
(ListChoice("dropdown_job", new Model(),myList, new myRenderer)) my
listchoice is no longer displayed as a dropdown but as a listbox.
If I instead of using the constructor with the model property call the
set model method (listChoice_job.setModel(new Model())) then it remains
displayed as a dropdown
Code snipplet:
// this gives a listbox
listChoice_job = new ListChoice("dropdown_job",new
Model(),jobcenter.toArray().getList(), new DataItemRenderer())
//this gives a dropdown
listChoice_job = new ListChoice("dropdown_job",
jobcenter.toArray().getList(), new DataItemRenderer())
listChoice_job.setModel(new Model());
Code snipplet end
It's that latter I want displayed.

Re: [Wicket-user] using feedback not based on labels
nice thing about having an interface is that you dont have to do that, you can aggregate on demand and for things like Iterator simply return a compound iterator. but this is more work.i guess your way works too. create a patch and attach it to our sf.net tracker and one of the core devels will merge it in.-IgorOn 5/9/06, Ittay Dror < [EMAIL PROTECTED]> wrote:Igor Vaynberg wrote:> hrm, so now if you want to join the two what do you do in getMessages() > of the compound impl?>> create a new arraylist and merge messages from the other two? do you do> the merged array generation on every call or keep it in a transient field?i copy the code from FeeedbackMessagesModel ;-) (it keeps the array in a transient field) >> -Igor>>> On 5/9/06, *Ittay Dror* <[EMAIL PROTECTED]> [EMAIL PROTECTED]>> wrote: >> ok, i have it. how do i send it?>> i created an AbstractFeedbackMessages, which has 2 abstract methods:> isReadonly() and getMessages(). the rest use them>> i'm thinking of maybe change it to ReadonlyFeedbackMessages and > FeedbackMessages which will extend it, and CompoundFeedbackMessages> will extend it also.>> what do you think?>> Igor Vaynberg wrote:> > maybe you can submit a patch > >> > here is what i would suggest> >> > extract IFeedbackMessages interface from FeedbackMessages and> create a> > CompoundFeedbackMessages impl, that way you can join the session and > > page messages yourself and still use the same utility methods in> > FeedbackMessages on the joined collection.> >> > how does that sound?> > > > -Igor> >> >> > On 5/9/06, *Ittay Dror* <[EMAIL PROTECTED]> [EMAIL PROTECTED]>> > [EMAIL PROTECTED] [EMAIL PROTECTED]>>> wrote:> > > >> >> > Igor Vaynberg wrote:> > > so you want to use it outside the model?> >> > outside of an IModel context, yes. > >> > >> > > but then feedbackpanel.anyMessage(int level) is just> > >> > > Page.getFeedbackMessages ().hasAnyMessage(new > > > ErrorLevelFeedbackMessage(level)) no?> >> > no, because the model joins the page messages and session> messages> >> > > > > > -Igor> > >> > >> > > On 5/9/06, *Ittay Dror* < [EMAIL PROTECTED]> [EMAIL PROTECTED]>> > [EMAIL PROTECTED] [EMAIL PROTECTED] >>> > > [EMAIL PROTECTED] [EMAIL PROTECTED]>> [EMAIL PROTECTED] [EMAIL PROTECTED] wrote:> > >> > > it will be too much of a pain, since most issues are > because i'm> > > using wicket in an existing application, built on struts.> > >> > > however, i would appriciate it if you could answer > some specific> > > questions.> > >> > > i'm trying to create my own feedback panel. an issue i> > encountered > > > is that FeedbackPanel has the anyMessages() method,> which i also> > > need, i can copy the code, but isn't it better to move> it to> > > FeedbackMessage, as static utility methods? or, better > yet,> > create a> > > FeedbackMessages class which has the logic found in> > > FeedbackMessagesModel, so it can be reused outside of the > > context of> > > a model?> > >> > > ittay> > >> > > Igor Vaynberg wrote: > > > > give us an html snippet of what you want as the end> result> > and> > > tell us> > > > where the components are. it is very difficult to > talk on> > such a huge> > > > abstraction level.> > > >> > > > -Igor> > > > > > > >> > > > On 5/9/06, *Ittay Dror* < [EMAIL PROTECTED]> [EMAIL PROTECTED]>> > [EMAIL PROTECTED] [EMAIL PROTECTED]>>> > > [EMAIL PROTECTED]> [EMAIL PROTECTED]> [EMAIL PROTECTED] > [EMAIL PROTECTED] > > > [EMAIL PROTECTED]> [EMAIL PROTECTED]> [EMAIL PROTECTED]> [EMAIL PROTECTED] >>> > [EMAIL PROTECTED] [EMAIL PROTECTED]>> [EMAIL PROTECTED] [EMAIL PROTECTED]> wrote:> > > >> > > >> > > > > > > > Igor Vaynberg wrote:> > > > > but what is really a problem then i dont> > understand? all> > > you want > > > > to do> > > > > is write out some _javascript_ based on feedback> > messages?> > > instead of > > > > > using a feedbackpanel add a label that> writes out the> > > _javascript_ you> > > > > want. you can get the messa
