Re: "Streaming" a huge ZIP file
IIRC, DownloadLink and Igor's anonymous class will lock the session, so if
you have one downloading over a very slow connection, other users will get a
timeout.

Re: "Streaming" a huge ZIP file
But still youj could generate to a tmp file onm disk and stream that.
But you xan also generate on the fly and stream that direcly to a
response stream

Does wicket support looping form elements...
Hi All, I have a large project I wrote in Echo1/Spring1 many years ago. I'm planning to rewrite this application. I'm trying to choose between Wicket/Spring2 or JSF/Seam. Because I used Echo you can tell I'm a believer in the advantages of Wicket over JSF. Critical to my choice is the ability to 'mount' user created eforms. So basically i'll need to loop over some SurveyQuestion objects and create wicket field components for some of the form elements on the page. In Echo it wasn't hard because you could either use the HtmlTemplate page (as we do for most of the app - hence the interest in wicket) or you can 'build' the page/forms by hand without a html template. JSF will allow me to loop in the view. I had planned to use Velocity/Freemarker integration to get this effect with Wicket but I just read in Pro Wicket that you cannot use these panels for form elements. I've read something about wicket fragments and the fact that you can use a wicket List/Loop object to display a list of panels or fragments but I'm thinking this was designed for master-detail type views and not really for programatically looping over a form definition and building a form. I'd very much appreciate if anyone illuminate me as to whether I will be able to build this in wicket or not?

"Streaming" a huge ZIP file
Hi there,
The downside of an easy-to-use framework is the influx of users with
little understanding of the underlying servlet technology, like me.
Observe:
I'd like to provide a ZIP file (could be TAR, anything Windows PCs can
save and later extract from) as a download, one that is potentially
too big to be kept in memory in full.
So I guess I'd need to "stream" it in chunks, or as a java stream or channel.
Can I do that from wicket?
Or does the servlet interface require a fully assembled response in memory?
Currently I assemble the ZIP file in a byte array in full, but it
feels awkward. Would extending WebResource fit the bill?
ByteArrayOutputStream bout = new
ByteArrayOutputStream();
ZipOutputStream zout = new ZipOutputStream(bout);
// Add entries
zout.finish();
zout.close();
Resource resource = new
ByteArrayResource("application/zip",
bout.toByteArray());
ResourceStreamRequestTarget target = new
ResourceStreamRequestTarget(resource.getResourceStream());
target.setFileName(new
SimpleDateFormat("MMddHHmmss").format(Calendar.getInstance().getTime())
+ ".zip");
getRequestCycle().setRequestTarget(target);
All suggestions are welcome.

RE: Creating a form submit listener using IBehavior
Are you trying to submit the form from within an ajax event? If so you can simply do: target.appendJavascript(getForm().getMarkupId()+".submit()");//get the markupId for the form and append javascript to submit it In any case, it seems like form.submit() might do what you are looking for? -Clay -Original Message- From: Ryan [mailto:[EMAIL PROTECTED] Sent: Tuesday, December 11, 2007 1:56 PM To: users@wicket.apache.org Subject: Creating a form submit listener using IBehavior All, I have a use case where I would like to submit a form via javascript and have wicket map this submission back to a java onSubmit method (using wicket 1.3-rc1). On the surface this is very similar to adding a SubmitLink, hiding the submit link markup elements, then using a javascript function to trigger the onclick handler for that SubmitLink. This approach works however I would like to find a more elegant solution.. Something that can be added to any form and not require changes to that form or its markup. Adding a hidden link seems hackish. This lead me to my first attempt which was to create a behavior that is added to the form that emulate's SubmitLink.getTriggerJavascript and render that javascript into a function. This doesn't look like it will work out because getTriggerJavascript uses a package private method Form.getHiddenFieldId() and also relies on the fact that the SubmitLink itself is a component within the Form (I am trying to create a behavior). My second attempt was to make use of Form.getJsForInterfaceUrl(interfaceUrl) passing in a url generated using form.urlFor(behavior, IBehaviorListener.INTERFACE). I could then use my behavior to add a javascript function that executes the javascript from Form.getJsForInterfaceUrl(interfaceUrl). This is not working for two reasons: 1) Form.getTriggerJavascript (line 1045 in wicket 1.3-rc1) requires the request target to be an instance of ListenerInterfaceRequestTarget ( IBehaviorListener.INSTANCE is creating a BehaviorRequestTarget). 2) requestTarget.getTarget() is returning the form instead of my behavior, so even if Form.getTriggerJavascript accepted BehaviorRequestTarget it would not execute my behavior. Clearly I am missing something about hooking into the submit process for a form. Could someone that has a better understanding of this area of wicket point me in the right direction?

Creating a form submit listener using IBehavior
All, I have a use case where I would like to submit a form via javascript and have wicket map this submission back to a java onSubmit method (using wicket 1.3-rc1). On the surface this is very similar to adding a SubmitLink, hiding the submit link markup elements, then using a javascript function to trigger the onclick handler for that SubmitLink. This approach works however I would like to find a more elegant solution.. Something that can be added to any form and not require changes to that form or its markup. Adding a hidden link seems hackish. This lead me to my first attempt which was to create a behavior that is added to the form that emulate's SubmitLink.getTriggerJavascript and render that javascript into a function. This doesn't look like it will work out because getTriggerJavascript uses a package private method Form.getHiddenFieldId() and also relies on the fact that the SubmitLink itself is a component within the Form (I am trying to create a behavior). My second attempt was to make use of Form.getJsForInterfaceUrl(interfaceUrl) passing in a url generated using form.urlFor(behavior, IBehaviorListener.INTERFACE). I could then use my behavior to add a javascript function that executes the javascript from Form.getJsForInterfaceUrl(interfaceUrl). This is not working for two reasons: 1) Form.getTriggerJavascript (line 1045 in wicket 1.3-rc1) requires the request target to be an instance of ListenerInterfaceRequestTarget ( IBehaviorListener.INSTANCE is creating a BehaviorRequestTarget). 2) requestTarget.getTarget() is returning the form instead of my behavior, so even if Form.getTriggerJavascript accepted BehaviorRequestTarget it would not execute my behavior. Clearly I am missing something about hooking into the submit process for a form. Could someone that has a better understanding of this area of wicket point me in the right direction? Ryan
Re: dropdownchoice
here is the version that stores the id in the model instead...maybe at
some point it can make its way into extensions or core
import java.util.List;
import org.apache.wicket.markup.html.form.DropDownChoice;
import org.apache.wicket.markup.html.form.IChoiceRenderer;
import org.apache.wicket.model.IModel;
public class DropDownIdChoice extends DropDownChoice
{
public DropDownIdChoice(String id, IModel model, IModel choices,
IChoiceRenderer renderer,
Class type)
{
super(id, model, choices, renderer);
setType(type);
}
@Override
public String getModelValue()
{
final Object id = getModelObject();
if (id != null)
{
return getConverter(getType()).convertToString(id, getLocale());
}
else
{
return NO_SELECTION_VALUE;
}
}
}

Re: dropdownchoice
Fair question. Why return the Id, instead of just using a Property model to bind the member field of an object to a child component's model? Thanks for your insight. Yevgeni: If you do that you will have to have an object (can be the same one that extends DropDownChoice) implement IChoiceRenderer, so that you can see the field you are interested in on the dropdown. And also do not forget to say setChoiceRenderer(this); In the constructor.

Google Wicket Public Calendar
I thought we already had one, but couldn't find it so i created one: http://www.google.com/calendar/embed?src=cGQwY29vanBodDduc3Fib3Q3dTJxNW1jNDhAZ3JvdXAuY2FsZW5kYXIuZ29vZ2xlLmNvbQ People who want to contribute to this calendar please feel free to ask me so that we can have a nice wicket calendar with User Group Meetings, Conferences and other Events. Martijn will set the release date in the calender for 1.3 and 1.4 ;) johan
Re: dropdownchoice
yes this is true, you have to have a selected object that comes from the
choices
Why is this so hard to understand? I find that completely logical.
Maybe with generics (1.4) this will be more clear
*
public* DropDownChoice(String id, IModel model, IModel> choices,
IChoiceRenderer renderer)
So if your model object ins an integer, Then you also have to have a List of
integers..
Are you guys working with pojos like: Person.getAddressId() instead of
Person.getAddress() ??

Re: dropdownchoice
I am not sure what the design decision was behind this and perhaps one of the
Wicket Gurus can weigh in on this but I ran into something very similar
recently, and here are my thoughts:
I think you are mixing the model object that backs the Dropdown and the
actual Broker object. They are not the same thing. For example, having
Broker id's in the final rendered HTML is a potential security risk.
That being said, I could not find a elegant solution to the same exact
problem. I ended up subclassing DropdownChoice. Adapted to your code, it
looked something like:
private HashMapmap = new HashMap();
...
//get a list of the String that will be your choices
for(Broker b : (Application)
getApplication()).getBrokerDao().getUniqueBrokers())
{
map.put(b.getName(), b);
}
setChoices(new ArrayList(map.keySet()));
...
public HashMap getMap()
{
return map;
}
Then, in your onSubmit() method for the containing component you can access
the Id of each broker like this:
brokerDropDown.getMap().get(modelObject.getBrokerName()).getId()
I hate this approach. I would love to have someone point me in a better
direction.

RE: JRPdfResource onResourceRequested() file dialog not displayed when using AjaxFallbackLink
I had a similar problem with showing a file download dialog from an ajax event, I got around it by doing target.appendJavascript(getMarkupId()+".submit()"); which submits the form, and then forwarding the user to the file in the onSubmit() method of the form.

Use ajaxCallDecorator and javascript. There is a jquery plugin, called blockUI. You can use it, or write something similar to get the same behavior. Regards, Alex.

Re: When to use getModelObject, getConvertedInput, getInput
you shouldn't call getConvertedInput() or getInput yourself except if you where making a special formcomponent itself. The model of an component lives as long as the component does. But the dropdownchoice (or all select tag components) have another special thing call IChoiceRenderer That first tries to convert the string to an option object. johan On Dec 11, 2007 1:47 PM, wicket user <[EMAIL PROTECTED]> wrote: > Hi, > > This is more a question of understanding models and input of a particular > component, lets say DropDownChoice (DDC) for example. > > You give it a model initially on creation, this has nothing to do with, in > the case of a DDC the selected values as that is supplied by the Choices > paramater in the constuctor. > > So we now have a DDC configured. > > A user comes along and selects a value, if we have and > AjaxFormComponentUpdatingBehavior associated we see that the > getModelObject > returns null as well as getConvertedInput but getInput actually has > something but it's in string form.

When to use getModelObject, getConvertedInput, getInput
Hi, This is more a question of understanding models and input of a particular component, lets say DropDownChoice (DDC) for example. You give it a model initially on creation, this has nothing to do with, in the case of a DDC the selected values as that is supplied by the Choices paramater in the constuctor. So we now have a DDC configured. A user comes along and selects a value, if we have and AjaxFormComponentUpdatingBehavior associated we see that the getModelObject returns null as well as getConvertedInput but getInput actually has something but it's in string form. Is this because we are intercepting the event before the input is converted to the model? Basically I'm never sure when to use which accessor and the trial and error method that I have been using so far is starting to scare me. I guess the lifecycle of model is what I really need to understand and googling hasn't thrown up much. I have read the wiki article on models but it doesn't go into details such as this... Anyway, it will be a nice thing to not have nagging me over xmas! thanks simon
Component.visitParents visits the calling component as well
Hi, I see that Component.visitParents() also visits the component on which the call is made. Is this behavior correct? If so, I think that the method name is a little bit confusing. The method MarkupContainer.visitChildren() doesn't visit the calling component, but only it's children (as the method name suggests).
