Re: Form FileUploadField maxSize does not work

[Igor Vaynberg]

so is the problem that the form being submitted is the outer form and
it doesnt support the inner form's maxsize?

Re: Can't update TextField via Ajax after a validation error

[Jason Lea]

When a field is submitted and there is a validation error, it doesn't 
update the model and the field will redisplay with the invalid input.  
This way the user can see what they typed and can fix the problem.
With your populate link, you are updating the model, but wicket won't 
look at the model because the field is redisplaying the invalid input 
(in your case an empty field).


If you want to update the underlying model value and ignore the previous 
failed validation you will need to clear the input.
You could use Form.clearInput() to clear all invalid fields or 
testInput.clearInput() perhaps.

It doesn't sound like this is exactly what I want, though. I do need my

validation works when the link that fills in the Integer behind the property
model is clicked first, but the same link populating and updating the field
stops working after a validation error.

Transparent resolver parent child working but cannot add third component

[david]

Hello all, I have a WebPage parent transparent resolver that displays the child 
page OK. The parent page is a tabbed menu and the child is a row of submenus. 
When the submenu child is clicked I want an added third component (a WebPage 
class) to be displayed. But instead I get the usual ugly 
WicketRunTimeException: component added but markup not found. All classes and 
HTML are in the same package. Obviously, this issue is the result of some 
mismatch in the hierarchy but I thought the transparent resolver would fix the 
hierarchy dilemma. I have studied every transparent resolver example I can 
Google but nothing jumps out as a diagnostic to perform to resolve this 
problem. I don't want to refactor all of the classes from markup inheritance to 
Panel if this can be avoided as this will in all-likelihood break the menu 
pages. Please advise.

Can't update TextField via Ajax after a validation error

[Neil Curzon]

Hi all,

I'm having a weird problem that causes an input to refuse to update with an
AjaxLink click method when there's been a validation error. One field in the
form has a property model pointing to an Integer value. It's set to
required, and there are other links that set the Integer value.

What I see is that when I first click a link that populates the Integer
under the required field, everything works fine. But when I click submit
first, the populate links stop working. The handlers are still invoked, but
the HTML that comes back in the Ajax Debug shows an input with value=""
(even though the getModelObject() for that TextField returns the proper
value in debugging statements). This results in the input always being
showed empty. If I do things in the proper order, I see the correct value
populate in the text field as expected. It's not just a display issue,
either. The form refuses to submit successfully at all if there was a
validation error first (and you don't manually enter anything into the
field).

Below is a simple application that reproduces the issue I'm seeing. I'm
using wicket 1.3.7 but I've tried 1.4.1 with the same result. Any help would
be greatly appreciated.

[Pedro Santos]

Hi Johannes,

recently I develop an jmx panel, to view and operate the applications
mbeans. And latter I discover that the wicket stuff already has one!
I rememer that, because in the ocasion I was afraid to start use the jmx
wicket stuff panel, due it has the wicket 1.3.1 on classpath, and the
project was using 1.4.1

Wicketstuff really needs some updates

[Johannes Schneider]

Hi,

I really love the work that has been put into WicketStuff. The world is
much better *with* WicketStuff.
But unfortunately several files are outdated and many releases are missing.

So at first I want to say thank you to everybody who has put work into
that project. Then I want to motivate those with commit rights to update
the projects and release some of the modules...
I am offering some donuts ;-)


Thanks,

Johannes

Why replace the CSS?  Just override it with your own.

Re: calendar or room/time reservation components?

[Troy Cauble]

Thanks, timeline looks very slick for time-lines.
But it doesn't appear to give you control of the non-time-axis.
For a room reservation system you might get

[room 1 ] [ room 2] [room 7]
 [room 3]
  [room 1]
8am 10am  12 am

(It'd be much better to see "room 1" own a row.)
Maybe if I use (abuse?) "bands" for rooms?

Re: Form FileUploadField maxSize does not work

[nytrus]

Yes igor, below there is the code, even if is not very short.
The issue is that when I click on upload1 button the submitting form is
form0 instead of simpleUpload.
Maybe I've bad-coded some part.

/** the upload panel, very similar to the wicket example **/
public class UploadFilePanel extends Panel {
/**
 * Form for uploads.
 */
private class FileUploadForm extends Form implements
IFormVisitorParticipant{
private FileUploadField fileUploadField;
public FileUploadForm(String name, IModel model, Bytes
maxSize){
super(name);
// set this form to multipart mode
setMultiPart(true);
// Add one file input field
add(fileUploadField = new FileUploadField("fileInput", model));
setMaxSize(maxSize);
}

@Override
protected void onSubmit(){
final FileUpload upload = fileUploadField.getFileUpload();
if (upload != null){
// Create a new file
File newFile = new File(getUploadFolder(),
upload.getClientFileName());
try{
// Save to new file
newFile.createNewFile();
upload.writeTo(newFile);
FileUploadForm.this.info("saved file: " +
upload.getClientFileName());
}
catch (Exception e){}
}
}
}

public UploadFilePanel(String id, Bytes maxSize) {
super(id);

// Add simple upload form, which is hooked up to its feedback panel
by
// virtue of that panel being nested in the form.
if (maxSize==null) maxSize = Bytes.kilobytes(100);
final FileUploadForm simpleUploadForm = new
FileUploadForm("simpleUpload", new Model(null), maxSize);
add(simpleUploadForm);

final FeedbackPanel uploadFeedback = new
FeedbackPanel("uploadFeedback", new ContainerFeedbackMessageFilter(this));
add(uploadFeedback);
}
}
/** the panel html **/




  




  

/** the test page **/
public class TestPage extends WebPage {
Form form0 = new Form("form0");
UploadFilePanel upload0 = new UploadFilePanel("upload0",
Bytes.kilobytes(100));
form0.add(upload0); /*** this upload DOES NOT check max size ***/
add(form0);

UploadFilePanel upload1 = new UploadFilePanel("upload1",
Bytes.kilobytes(100));
add(upload1); /*** this upload DOES check max size ***/
}
/** test page html **/

Re: Palette rendering issue

[Troy Cauble]

Thanks,

I ended up making "Palette_noOrdering.html" and overriding
getVariation().  It works for finding my altered html.

But then I tried to make a small change in palette.css and can't seem
to get it picked up.  What's the trick to naming and placement for
replacing the css?

Also, I couldn't follow the references to "sourcePath" on the wiki page
(below) or in the referenced javadoc.  Can someone explain how that
alternative works?

Re: Setting th

you have to go low level and most likely override your form's
process() method to do this.

you can get the value by calling formcomponent.getinput() which will
give you the raw unprocessed value from the http request.

Doubtful; Ajax is primarily concerned with NOT replacing the whole page. 
If you always replace the page use a "normal" link instead which lets you 
set a RedirectRequestTarget for instance.

Re: radio and radiogroup default "checked" not working?

[Seven Corners]

I have a similar issue, but I don't know which radio should be checked until
runtime.  So I can't hard-code it in the HTML; I have to determine it from
my DAO in the radiogroup's parent panel constructor.  I'm using the model to
determine which radio to select, and it works fine once you click, but my
problem is that nothing is selected when the page first loads.  Here is the
code:

// This sets up the radiobuttons
private enum eContentTypeControl { TEXTFIELD, DROPDOWN };
private class ContentTypeControlBean implements Serializable
{
private static final long serialVersionUID = 1L;
private eContentTypeControl m_control = null;

public ContentTypeControlBean( eContentTypeControl control )
{
m_control = control;
}

public eContentTypeControl getControl()
{
return m_control;
}

public void setControl( eContentTypeControl control )
{
m_control = control;
}
}

// Figure out which radiobutton should be selected
List mimeTypeList = model.getCommonMimeTypes();
eContentTypeControl contentTypeControl = null;
if ( mimeTypeList.contains(
model.getCachedDefaults().getContentType() ) )
{
contentTypeControl = eContentTypeControl.DROPDOWN;
}
else
{
contentTypeControl = eContentTypeControl.TEXTFIELD;
}

// Create the radiogroup with the right 
m_ContentTypeRadioGroupBean = new ContentTypeControlBean(
contentTypeControl );
RadioGroup contentTypeRadioGroup = 
new RadioGroup( 
"contentTypeRadioGroup", 
new PropertyModel(
m_ContentTypeRadioGroupBean, "control" ) );
...
m_rbUseTextFieldContentType = 
new Radio( 
"textfieldContentType", 
new Model( new
ContentTypeControlBean( eContentTypeControl.TEXTFIELD ) ),
contentTypeRadioGroup );
contentTypeRadioGroup.add( m_rbUseTextFieldContentType );

m_rbUseDropDownContentType = 
new Radio( 
"dropdownContentType", 
new Model( new
ContentTypeControlBean( eContentTypeControl.DROPDOWN ) ),
contentTypeRadioGroup );
contentTypeRadioGroup.add( m_rbUseDropDownContentType );

and here is the HTML:

 

 

The dropdown radio is checked when the page loads if I have "checked =
'true'" in the HTML but since I don't know whether it should be checked at
compile time, I can't do that.  I tried using an AttributeModifier in the
parent panel's constructor but it has no effect:

if ( contentTypeControl == eContentTypeControl.TEXTFIELD )
{
m_rbUseTextFieldContentType.add( new AttributeModifier(
"checked", new Model( "true" ) ) );
m_rbUseDropDownContentType.add( new AttributeModifier(
"checked", new Model( "false" ) ) );
}

Flash/ExternalInterface does not work in IE if movie is fetched via Wicket/Ajax

[Mikko Pukki]

Hi,

This example demonstrates that ExternalInterface fails with IE only if movie is 
fetched via Wicket/Ajax.

ajaxtest.zip:
(http://download.syncrontech.com/public/ajaxtest.zip)

Page "first.html" fetches "second.html" page via Ajax. Second.html has Flash 
movie
that calls JavaScript methods with ExternalInterface and produces output
"Start..."
"ExternalInterface.available:true"
"ExternalInterface.objectID:testId"
"fromJs:text from js (first.html)"

This works both FF 3.5 and IE 7/IE8


quickstart_noname.zip:
(http://download.syncrontech.com/public/quickstart_noname.zip)

Same demonstration with wicket. This fails with IE

"Start..."
"ExternalInterface.available:true"
"ExternalInterface.objectID:null"
"fromJs:null"

ObjectId is null and JavaScript call does not return any value.

We are aware about EI/IE problems in past, but any of those does not seem to 
fit here.

Wicket 1.4.1, Flash Player 10, IE 7/8, FF 3.5

Has anyone encountered any similar behavior and/or has found any workaround?
Should I create a Jira issue?

Re: DropDownChoice and hibernate entities

[Martin Makundi]

Hi!

I have good experience from decouping hibernate and wicket. With this
I mean that what ever happens in wicket, should not logically affect
persitence.

This means that when I select something from a ddc, it is the primary
key that counts. If I need the actual object then I have a locking
mechanism in Hibernate to handle the different race conditions that
might occur.

And ofcourse, when I set  a foreign key I never automatically update
the foreign row. This reduces the amount of race situations.

DropDownChoice and hibernate entities

[Iain Reddick]

I'm having difficulty in seeing the best-practice way of handling DDCs 
who's choices are hibernate persisted entities.


Obviously the selection in this case would be a reference to a persisted 
entity, which is inherently bad, as this would put the entity into the 
session and also result in a "stale" entity reference on the next 
request (assuming you are using OSIV filter).


I'm aware that on form submit, the HTML selection results in a "fresh" 
object being pulled from the DDC choice list and set as the selection. 
As long as the choices are loaded dynamically, this works (although the 
selected entity will end up in the session).


However, I am using a wizard in the app that I am working on and want to 
pre-select a choice from a list of persisted entities. This DDC is used 
in step 3, which gives a hibernate "no session" exception when when the 
step is reached. This is understandable, as wicket's rendering needs 
will cause an attempted initialization of the proxy, which is attached 
to an old session.


The obvious solution is for the selection to be the entity's id.

What is the best way of handling this situation?

Form FileUploadField maxSize does not work

[Nicola Tucci]

I'm working with a file upload, using
http://www.wicket-library.com/wicket-examples/upload/single as example.

I've created an UploadPanel very similar to UploadPage.java of the example
(with the FileUploadForm form).
Well I've maxsize set to 100K and this check work if I add my uploadpanel to
the WebPage.

But If I add the upload panel to a form, the check does not work anymore.
The difference is that without outer form, the submit button of the upload
panel belong to FileUploadForm (with maxSize set).
With the outer form, the resulting submitting form correspond to the outer
form. I don't understand this as I'm still clicking the same submit button
of FileUploadForm. In this way, the maxsize is the one set in the outer form
(which I don't want to set! I want to have my UploadPanel component with
maxsize passed as parameter).

Re: Dynamic Optgroups in Wicket

[gary black]

Thanks Mike and everyone who responded.

I did manage to find a working solution by creating a OptGroup component by 
extending WebMarkupContainer and using fragments...
But was then was disheartened as it appears that you cannot nest optgroups 
inside one another in html - To represent the multiple levels within my list 
hierarchy.
If there is such a way to nest optgroups within one another, then I would very 
much appreciate the info but I suspect you can't from what I've read.
My final solution was just to use a select component and replace the labels 
using hyphens before the text to represent the current level:
Item1---Item1-1---Item1-2---Item1-3Item2---Item2-1---Item2-2--Item2-2-1--Item2-2-2---Item2-3Item3
Thanks

I created a custom implementation of SelectOptions and SelectOption (in 
wicket-extensions) that I use to render the optgroups.  What I do is use a 
wrapping object that contains the business object and the name of the optgroup 
and if it is the first or last wrapping object with that particular optgroup 
name.

Then I override the SelectOptions.newOption(...) to wire in my custom 
CustomSelectOption.  Note that newOption() is called in order for each option 
in the list so tracking the last optiongroup name can be used to determine if 
its changed or not. i.e. if the Custom.SlectOption.startOptionGroup or the 
CustomSelectOption.endOptionGroup parameter should be true or false.

This is the only change in the selectOption:

 �...@override
   protected void onRender(MarkupStream markupStream) {

       /*
        * Write out the option group wrappings if this is the first or last 
option in a particular group.
        */
       if (startOptionGroup) {
           getResponse().write("" + 
optionGroupName + "\n");
       }
       super.onRender(markupStream);
             if (endOptionGroup) {
           getResponse().write("\n");
       }
   }

The setting of the start and end flags are handled in 
SelectOptions.newOption(...) and then the above code is used to render the 
options into optiongroups.

Let me know if you need more details,

Regards,

Mike

Question regarding file uploading

[Daniel Dominik Holúbek]

Hello,i've got just one question.
I would like to make a photo gallery, and thus I need to let users upload
their images.
But if I redeploy my webapp afterwards, would I loose those images?
If yes, is there any workaround?

Thanks :)
