[Wicket-user] OnChangeAjaxBehavior and Repeater issue on FireFox

2007-07-30 Thread Flavius

Greetings.

I have a page that uses the new OnChangeAjaxBehavior. When values
are typed into the text field, it updates a RepeaterView. It works
with the first key press but, almost always, it doesn't fire the onUpdate()
event on subsequent key presses, but only on FireFox (I'm using 2.0.0.5).

It works fine with IE 7. To make sure I didn't configure anything
incorrectly,
I copied the OnChangeAjaxBehaviorPage sample to my project and ran it.
That works fine for both IE and FireFox. Since I can reasonably eliminate
environment, it seems like the probable issue has something to do with
the repeater code, or its container. In looking at the AJAX DEBUG window
it looks like the ajax is completing successfully.

I'm using the wicket 1.3.0-beta2 build. I also tried now with the
snapshot from today (561103). The same results.

I put up a test page at http://24.248.103.44/pages/TestAjax. The
page has the java code on it.

IE works fine, but FF fails after the first key press.

I also have the sample from examples too:

http://24.248.103.44/pages/OnChangeAjaxBehaviorPage

That works for IE and FF.

I'd appreciate any insight into what I may be doing wrong.

Re: [Wicket-user] setVisible on Fragment with AjaxFormComponentUpdatingBehavior

2007-05-23 Thread Flavius

There are no errors. I did try setting the outputMarkupId to
true for the fragment. In the examples (and in my own code
with just the TextField), setting the container was sufficient.
Adding this to the Fragment had no effect.

Here is the Ajax output from the console:

INFO:

Like I mentioned, if I just add a TextField (or any other form component)
it works great. But my pages need to remove the control
and label. In a couple of places, it needs to remove several controls,
a prime candidate for a fragment or panel, imho.

I've read other threads discussing setting the visibility like this:
http://www.nabble.com/Changing-visibility-via-ajax-tf1974532.html#a5418508

So I must conclude I'm doing something wrong.

How does it not work? What does the Ajax debug console say?
What is the error message / stack trace, if any?

Looking quickly it occurs to me that maybe you should set
outputMarkupId(true) to the Fragment. If this is the case,
it should be obvious from the error message on Ajax debug
console.

Re: [Wicket-user] setVisible on Fragment with AjaxFormComponentUpdatingBehavior

2007-05-23 Thread Flavius

The fragment contents appear fine.
When I change the value on the dropdown, I expect the
AjaxFormComponentUpdatingBehavior.onUpdate() to set
the visibility to false.

My dropdown has this added:

dropDown.add(new
AjaxFormComponentUpdatingBehavior(onchange)
{
protected void onUpdate(AjaxRequestTarget
target)
{
target.addComponent(container);

text2Fragment.setVisible(false);
}
});

Now if I substitute a TextField instead of a fragment (or panel), it
correctly
sets the visibility to false. But with the fragment, it stays visible when
the
onchange event fires.

I put up a couple of test pages, if you want to see:
http://24.248.103.44/pages/Test (this is just the component, which works)
http://24.248.103.44/pages/Test2 (this is with the fragment, which does not)

I included the java source on each page.

[Wicket-user] setVisible on Fragment with AjaxFormComponentUpdatingBehavior

2007-05-22 Thread Flavius


I am trying to setVisible on a Fragment using the
AjaxFormComponentUpdatingBehavior object.
It doesn't seem to work.  I've also tried this with a Panel and that's not
working either.

However, if I use a component, like a TextField, that works.

In my java, this is the pertinent code for my Form:

DropDownChoice dropDown = new DropDownChoice(dropDown, new Model(),
choiceList);
add(dropDown);

final WebMarkupContainer container = new WebMarkupContainer(container);
container.setOutputMarkupId(true);

final Text2Fragment text2Fragment = new 
Text2Fragment(text2Fragment,
text2FragmentId);
container.add(text2Fragment);
add(container);

dropDown.add(new 
AjaxFormComponentUpdatingBehavior(onchange)
{
protected void onUpdate(AjaxRequestTarget 
target)
{

target.addComponent(container);
text2Fragment.setVisible(false);
}
}); 

My fragment:
private class Text2Fragment extends Fragment
{
public Text2Fragment(String id, String markupId)
{
super(id, markupId);
TextField text2 = new TextField(text2);
add(text2);
}
}



My HTML:
tr
tdDropDown:/td
tdselect wicket:id = 
dropDown/select/td
/tr   
tr
tdText 1/td
tdinput wicket:id=text1/td
/tr
--spaces in span are for nabble 
sp an wicket:id=container 
sp an wicket:id=text2Fragment/sp 
an
/sp an

tr
tdText 3/td
tdinput wicket:id=text3/td
/tr

My Fragment:

wicket:fragment wicket:id=text2FragmentId
tr
tdText 2/td
tdinput wicket:id=text2/td
/tr
/wicket:fragment

If I put the text2 TextField in place of the fragment, the control
successfully
disappears.  I want a fragment so I can also remove labels, et al.

I'd appreciate any feedback on what I'm doing wrong.

Re: [Wicket-user] Receive event when user navigates away from current page

Thanks Martijn.

getBodyContainer().getBodyContainer().add(new AjaxEventBehavior(onunload)
{
protected void onEvent(AjaxRequestTarget target)
{
//handle cleanup here
}
});

This works well, except it doesn't fire when the browser is closed.
I'm keeping a ref to uploaded files in a list on the session. When
valueUnbound fires in my session, any remaining files that have
not been handled can be removed then.

That should cover BSOD, and any other client issues.

Martijn Dashorst wrote:

body.onunload could be your friend

However, don't depend on this behavior to be a failsafe: kill -9 will
not trigger the body onunload in the browser, or a power failure on
the client side, or a BSOD, or ...

Re: [Wicket-user] DropDownChoice binding question

2006-12-31 Thread Flavius



ok, I see where you're going with this.
very cool.

My enum is in a helper class and I started writing conversion methods in the
helper class.  But I like the way you wrapped your conversion methods
 in a class to use on the Page class.

I also gave some thought last night to using a MapInteger, String with
the same conversion technique.  Then my dropdown uses Integers and
I can do a map.get() in getDisplayValue() for the String.

Thanks for your help, Igor.

 you are passing a list of enum objects into the list model of the dropdown

 so there are two ways to do this
 
 you can pass in a list of ints into the choice component, that way the
 selected int will be set into your model
 
 or you can write a model decorator that does the transform
 
 class SizeEnumToIntModel extends Model {
private final IModel delegate;
public SizeEnumToIntModel(IModel delegate) {
  this.delegate=delegate; }
 
   public Object getObject(Component c) {return Size.forValue(
 delegate.getObject(c); // convert int to enum }
   public void setObject(Component c, Object o) {
 delegate.setObject(((Size)o).getintvalue();
 // convert enum to int }
   public void detach() {  delegate.detach(); }
 }
 
 then
 
 new DropDownChoice(id, new SizeEnumToIntModel(new PropertyModel(form,
 size))
 
 you lose the nice compound model syntax, but oh well
 
 you might also be able to use a convert to accomplish the same, but i
 havent
 looked into that

[Wicket-user] DropDownChoice binding question

2006-12-30 Thread Flavius


Greetings,

I am trying to take the value (only) of a DropDownChoice
and put it in a model set on the Form.

Ideally, I'd like to use a (java 5) enum, but any type of
name value pair will work.

For example, if I'm trying to set the size of a Shirt class, 
here is my Shirt, and a sample enum:


public class Shirt
{
private int size;
private int color;  
//. . . 
//(setters and getters removed to compact)
}

public static enum SIZE
{
Small(2),
Medium(4),
Large(6),

private String id;

SIZE(String id)
{
this.id = id;
}

public String getId()
{
return id;
}

public String getName()
{
return id +  -  + this.toString();
}
}

Now, in my Form, I set the shirt as a model.  When I add my size
DropDownChoice to the form, I am binding it to the size field of my
Shirt class:


private class InputForm extends Form
{
public InputForm(String name)
{
super(name, new CompoundPropertyModel(new Shirt()));


DropDownChoice sizeChoice = new DropDownChoice(size,
Arrays.asList(SIZE.values()),   

new ChoiceRenderer(name, id));

sizeChoice.setRequired(true);
add(sizeChoice);
//. . .
}

}

When I submit this form, it fails because I get a Small, Medium, or
Large
object back.  What I want is the id of the selected object.
I looked at the examples in DropDownChoicePage.java in the compref package
of the
wicket examples and I could do that: create a list of Integers and use a
switch
or other technique to get the display value.

What I really want to do is bind the id property of the enum to the
Shirt.size property.
I've done this in reverse with a PropertyModel, binding a property of the
model to a field
on the page.  I having some trouble doing it this way.

I read through a number of the posts on DropDownChoice as a search item. 
None seem to hit the
nail on the head.  One poster mentioned using ChoiceRenderer, but I'm not
following how
that would work.

Any suggestions would be greatly appreciated!
I'm using Wicket 1.2.3 and java 5 in Tomcat.

Re: [Wicket-user] DropDownChoice binding question

2006-12-30 Thread Flavius



I tried this:

DropDownChoice severityChoice = new 
DropDownChoice(size,  
Arrays.asList(SIZE.values()), 
new ChoiceRenderer()
{
public Object getDisplayValue(Object object)
{
return ((SIZE)object).getName();
}

public String getIdValue(Object object, int 
index)
{
return ((SIZE)object).getId();
}   
});

The page renders fine.  But when I submit the form, I get this error:

WicketMessage: unable to set object Small, model:
Model:classname=[wicket.model.CompoundPropertyModel]

Root cause:

wicket.util.convert.ConversionException: Cannot parse 'Small' using format
[EMAIL PROTECTED]
at
wicket.util.convert.converters.AbstractConverter.newConversionException(AbstractConverter.java:72)

As I understand it, it's trying to set an int in the Shirt model for size,
but the drop down returned the Small object.  What I really need is
Small.getId().  So I need to tell the form to bind the id property of the
return object to the field size

 IChoiceRenderer allows you to specify the id and display values for a
 DropDownChoice.  It's exactly what you're looking for.  To explain a bit:
 
 getDisplayValue(...) - returns the value you want the user to see. 
 Small,
 Medium, etc.  This is where you'd return SIZE.getName().
 getIdValue(...) returns the value submitted to the application.  This is
 where you'd return SIZE.getId().

[Wicket-user] Wicket 1.2.2 home page loads twice

2006-10-26 Thread Flavius



I'm new with wicket and started a vanilla project.  I created my application
class which extends WebApplication and defined a home page called Home.java
(and Home.html).

When I nav to the root of the app, it successfully takes me to the home
page.
But the app loads that page twice.  I am determining this because
in the constructor I am logging the value of getId().

In debug mode, first time through getId() = 0, and 2nd time through
getId() = 1.

I want to think I misconfigured something (like page pool size or
something),
but the only configuration I've done is the web.xml, which I mimiced from
one of the wicket-examples projects I looked at.

I've googled a bit and can't find anything quite like mine.

I'm running this with both merve tomcat (5.5.17) and jetty launcher.
Same behavior from both of these.

Any suggestions on where to look would be appreciated.

Re: [Wicket-user] Wicket 1.2.2 home page loads twice

2006-10-26 Thread Flavius



I found the issue.

I'm putting the images in for the home page.

One tag didn't have an entry for the src, like

img src= . . . .

That was calling the home page.  :-(
