Re: few (not only) AutoCompleteTextField questions

dlipski wrote:

Hi,

First, problem description:
Recently I was asked to change DropDownChoice field into
AutoCompleteTextField.
Everything was ok untill I noticed that old DropDownChoice field has
attached OnChangeAjaxBehavior.
Ofcourse what works well with DropDownChoice doesnt work as I want with
AutoCompleteTextField.
The problem is that I want to update a model after user selects one of
choices(from autocomplete) not after any change of text field.
I found getOnSelectJavascriptExpression method in
AbstractAutoCompleteRenderer (since Wicket 1.4 ?) and I thought that it
would be a good place to call some JS to update text field model.
I looked at
http://cwiki.apache.org/WICKET/calling-wicket-from-javascript.html to see
how to call server side Wicket code from JavaScript.
Next I had the idea to attach to text field
AjaxFormComponentUpdatingBehavior and call its getCallbackUrl() from
JavaScript returned from mentioned earlier
getOnSelectJavascriptExpression().
The problem is that AjaxFormComponentUpdatingBehavior expects event name
in constructor - in this case I dont need any onXXX event because I will
call its getCallbackUrl() directly from JS.

Now few questions:
1)How to update (via Ajax) model of some FormComponents from JavaScript?
Do I have to attach AjaxFormComponentUpdatingBehavior to some dummy event
and call its getCallbackUrl() directly in JavaScript ? If so, its kind of
hacking for me and AjaxFormComponentUpdatingBehavior should provide
no-argument constructor.

2)Does JavaScript returned from getOnSelectJavascriptExpression is called
after corresponding TextField value has been set ?

3)At Wicket wiki I found description how to work with
AutoCompleteTextField and Models:
http://cwiki.apache.org/WICKET/autocomplete-using-a-wicket-model.html
I dont understand why this problem is not solved by subclassing directly
form AutoCompleteTextField and overriding getConverter and provide some
custom converter ?

Ps. My colegue told me to attach AjaxFormComponentUpdatingBehavior to
onBlur event, maybe this is the solution ? (but still, for me better place
to update a model is in Javasript from getOnSelectJavascriptExpression()
than in onblur event handler...)

Best regards
Daniel

It was as simple as using a AjaxFormComponentUpdatingBehavior... I was
confused because I started with OnChangeAjaxBehavior and it was broking
AutoCompleteTextField - thats why I started thinking of diffrent approaches.

BTW. Why AjaxFormComponentUpdatingBehavior works well with
AutoCompleteTextField and OnChangeAjaxBehavior doesnt ? Is it a bug in
OnChangeAjaxBehavior or the purpose of this class is different ?

Regards Daniel

OnChangeAjaxBehavior receives only first input character

2008-10-28 Thread Daniele Dellafiore

Hi all.

I am using an OnChangeAjaxBehavior on a textField to filter contents
of a table.
My code is very similar to this example:
http://www.wicket-library.com/wicket-examples/ajax/on-change-ajax-behavior

The problem I have is that the first input character is received and I
can get it in the onUpdate method of the Behavior. Then it stops
sending event, the wicket ajax debug console confirm that nothing is
sent anymore. If I remove and give the focus back to the field, I
receive a new character, and only one again.

Here is the debug console output for the first char I receive.

INFO: focus removed from
INFO: focus set on filter5

Change row appearance in a DataGrid

2008-10-28 Thread bjolletz


Hi!

I've just started learning Wicket and like it very much so far. I've found
the very nice DataGrid component, for which I have a question:

Is it possible to alter the appearance of a row in the grid in some custom
way? What I want to do is that depending on my row data, I want all text in
certain rows to be printed with bold text-weight. In other words, I want to
add a class attribute to some of the rows, for which I can provide a style
sheet.

Is this possible in some way?

Thanks in advance!

Re: Change row appearance in a DataGrid

Override newRowItem() and decorate it however you want (using

Hi Guys

The JQuery stuff project arent compiling, seems to be dependant on

Re: DataTable cell link


Hi
I dont know wicketopia project (and any of its classes like FragmentColumn)
so I can misunderstand your idea but as far as I am able to read that code
It looks like you are adding a link to the table cell, not making a cell
itself a link.

If I understand your code it is familar to:

tdlt;agt;textlt;/agt;/td

but Im wondering how to achive:
td on click=xyztext/td

where xyz is code generated by Wicket (like in Link component class)

If I misundestood you could you give me some more details hot to make cell

Re: Change row appearance in a DataGrid

2008-10-28 Thread bjolletz


Thanks for the very quick reply!

I may be stupid but DataGrid doesn't seem to have a newRowItem() method to
override. I did some googling and found that you can do just this for
DataGridView, but I'm using DataGrid, which does not extend from
AbstractGridView (which has the newRowItem method), but from AbstractGrid.

Am I missing something obvious here?

Re: no title in ExternalLink

Yeah you can do that, you can do it heaps of different ways, but why  
not have a title field on an ExternalLink component, its such a basic

Currently this is only achieved by using AttributeAppender and  
setting

the title attribute onto the link component. I propose a new
construcotr that takes the title attribute as a parameter (or the
ExternalLink set a title by default).

I have filed a Jira ticket here:

There are lots of ways of making accessibility happening, but throwing

Instead of taking this narrow vision, perhaps start a discussion of
how we can make accessibility easy to implement, while not raping our

 Yes you can add it manually, but you can do many things manually. If the

 If you don't manually add it, you won't get a title on your link.

 Come on, lets get some accessibility happening. Then we can tout Wicket as

problem with PropertyModel and setDefaultFormProcessing(false) for button

2008-10-28 Thread itayh


Hey,

I have a page that contain a hidden form. When the user press on Add Item
or Edit Item then I set the visability of the form to true and the user
can add details and the OK button save the data and set the visability of
the form to false.
The problem is if the user press on cancel. I need to set
setDefaultFormProcessing(false) for the cancel button (since I don't want to
do validation checks) but It cause the next problem:
After the cancel press next time I press the Add Item or Edit Item the
data that I see is the old data (The one I press cancel on)
Changing setDefaultFormProcessing(true) for the cancel fix that problem.

Here is the code:

private String name;
TextField nameField = new TextField(name, new PropertyModel(this,
name));
addGameItemForm.add(nameField);

...

Link link = new Link(edit-link, item.getModel()) {
public void onClick() {
onEditItem((Item) getModelObject());
}
};

...

Button save = new Button(save, new Model(Save)) {
public void onSubmit() {
onSaveItem();
}
;   
addItemForm.add(save);

addItemForm.add(new Button(cancel, new Model(Cancel)) {
public void onSubmit() {
onCanceItem();
}
}.setDefaultFormProcessing(false));

private void onCancelGameItem() {
addItemsForm.setVisible(false);
}

protected void onEditItem(Item item) {
name = gameitem.getName();
addItemsForm.setVisible(true);
}

In case that the setDefaultFormProcessing is false for the cancel button,
the name is not the one I press edit on. It is the old one.

Any Idea?

 Button save = new Button(save, new Model(Save)) {
public void onSubmit() {
onSaveItem();
}
 ;
 addItemForm.add(save);

 addItemForm.add(new Button(cancel, new Model(Cancel)) {
public void onSubmit() {
onCanceItem();
}
 }.setDefaultFormProcessing(false));

 private void onCancelGameItem() {
addItemsForm.setVisible(false);
 }

 protected void onEditItem(Item item) {
name = gameitem.getName();
addItemsForm.setVisible(true);
 }

 In case that the setDefaultFormProcessing is false for the cancel button,
 the name is not the one I press edit on. It is the old one.

 Any Idea?

Re: wicket and 508 compilance

What are you referring to when you say DDC? The Dewey Decimal System?  
Used by pretty much every library around the world making it really  
easy to find books? I'd call that accessible.


So my vision for wanting to enforce a bit of accessibility on the web  
is narrow(?), but no one wants to move forward with the most simple of  
modifications to make it easier to implement accessibility. The most  
basic of things to do would be to update the JavaDocs for the API to  
say:


NOTE: you should always include an AttributeModifier/Appender (or  
roll your own implementation) to include the title attribute on every  
link. here's some examples, etc


Or would that be too much bloat as well?

Yes you can add it manually, but you can do many things manually.  
If the
constructor is there it allows people to automatically take  
advantage of it.

If you don't manually add it, you won't get a title on your link.

Re: problem with PropertyModel and setDefaultFormProcessing(false) for button

 Hey,

 I have a page that contain a hidden form. When the user press on Add

 The problem is if the user press on cancel. I need to set
 setDefaultFormProcessing(false) for the cancel button (since I don't want
 to
 do validation checks) but It cause the next problem:
 After the cancel press next time I press the Add Item or Edit Item
 the
 data that I see is the old data (The one I press cancel on)
 Changing setDefaultFormProcessing(true) for the cancel fix that problem.

 Here is the code:

 private String name;

 name));
 addGameItemForm.add(nameField);

 ...

 Link link = new Link(edit-link, item.getModel()) {

 In case that the setDefaultFormProcessing is false for the cancel button,
 the name is not the one I press edit on. It is the old one.

 Any Idea?

Well the last post was unclear about which patch he was referring to  
(Javadoc or codebase).


From the previous discussions, it's clear that a patch for a new  
constructor won't be considered. I will, however, get some information  
to extend the Javadocs and submit that.

Write XML response

Hello,

I wonder if you can help.  I'm trying to send back some XML from an 
AbstractAjaxBehavior  like this:

public class MyAjaxBehavior extends AbstractAjaxBehavior {

@Override
public void onRequest() {
 
String reply = XML document as String.
RequestCycle.get().setRequestTarget(new 
StringRequestTarget(reply));
 
} 
}

How can I set the response type to text/xml ?  The clients get the 
response okay, but the fact that they don't know it's XML is causing 
problems in Firefox and Chrome.

Many thanks,

Re: Migration to 1.4 - generic headache

yes it sucks. i agree. personally i prefer code written against wicket
1.3. even in 1.3 i hardly had to cast anything and even with those
casts i do not remember getting any class cast exceptions.

i do think imodelt makes a ton of sense, but the types on components
are pretty bad.

in 1.5 i have an idea to fix it, but i am not sure it is going to work
without giving up compound property model. the idea is to remove the
default model from component completely and have user keep the model
as a field. in ondetach() we can then detach any fields that are
imodel via reflection. this will neatly solve all generics problems
but it has limitations.

anyways, we will see how it goes. until 1.4 i think the generics will
stay the way they are unless we hear a ton of users complaining.

 Hi Guys,

 In the weekend I tried to migrate our application to wicket 1.4.
 I was very happy to use generics with wicket but now I frustrated.

 I love Wicket and I know it is nobody fault (it java fault! :)) but the
 generics sucks.

 Our application is quite big, more than one thousand classes and after
 adding generics
 the code looks awful and it is unreadable. I could live with that but
 especially frustrating are
 more than 4.000 warnings that I have now.

 Most of them I cannot fix. For example the warnings apply to the components
 that don't have models but I have to add them a type. What type? Any?
 Example:

 add(new Link(link) { //warning here
 @Override
 public void onClick() {
 //do something here
 }
 });

 I have a warning here because I didn't set a type of Link. But it doesn't
 have any model. I know I can add @SuppressWarnings(unchecked) but I don't
 want to do
 that in more than 4000 places in my code. If I do than I will loose all the
 warnign event that I would to have or could save me in the future.

 So a question is there any way to workaround about this warnings problem?
 I don't want to stay with wicket 1.3 because I realize that it will be
 abandon in a year or something.


 Thanks in advance,
 Artur

Since r4284 wicketstuff-parent/pom.xml has this:
 properties
java.src.version1.5/java.src.version
wicket.version1.4-m3/wicket.version
slf4j.version1.5.2/slf4j.version
runtime.logtarget/velocity.log/runtime.log
/properties


Where did you see 1.3.1 ?

 Hi Guys
 
 The JQuery stuff project arent compiling, seems to be dependant on 
 Wicket 1.4 and using generics. But the pom uses this parent:
 groupIdorg.wicketstuff/groupId
 artifactIdwicketstuff-parent/artifactId
 version2-nojavadoc/version
 Which includes wicket 1.3.1...
 
 Whats up?

Re: few (not only) AutoCompleteTextField questions

probably because textfields do not receive onchange event, or
something else was hijacking it.

BTW. Why AjaxFormComponentUpdatingBehavior works well with
AutoCompleteTextField and OnChangeAjaxBehavior doesnt ? Is it a bug in
OnChangeAjaxBehavior or the purpose of this class is different ?

Re: wicket and 508 compilance

both 1899 and 982 are pretty friggin vague :)

how often are link titles dynamic? i am thinking not very often at
all, so why add another imodel slot to make the component event bigger
for a small percantage of usecases.

in most cases a wicket:id=external-link title=
wicket:message=title:key-to-title../a works just fine for
internationalization. for the very few times where you do need a
dynamic title you can use an attribute appender or subclass
externallink and write a trivial implementation.

we try to keep the core components with as small a footprint as
possible, but we also make them pretty damn trivial to extend.

Re: no title in ExternalLink

2008-10-28 Thread Michael Sparer


I always go for accessibility and each of my links do have a title and I'd be
the last one to say that accessibility (and usability) isn't important. But
I think the footprint of the components should be kept as small as possible.
It isn't hard to extend them anyway. If you only use titled externallinks
(like I do) just subclass externallink and add an abstract method to return
the title. This way you're forced to come up with a decent title - which in
turn improves accessibility/usability. then you're not tempted to use a
default constructor ... well just my two cents - if the JIRA goes through,
I'll be fine with it too :-)

Re: DataTable cell link

2008-10-28 Thread Michael O'Cleirigh


Hi Daniel,

If you subclass DefaultDataTable there is a protected method call 
newCellItem(...) that you can use to attach the onclick class onto the td.


like:

class MyDataTable extends DefaultDataTable {
/* (non-Javadoc)
* @see 
org.apache.wicket.extensions.markup.html.repeater.data.table.DataTable#newCellItem(java.lang.String, 
int, org.apache.wicket.model.IModel)

*/
   @Override
   protected Item newCellItem(String id, int index, IModel model) {


   Item cell = super.newCellItem(id, index, model);


   cell.add(new AttributeAppender(onclick, new Model 
(someJavascriptCall();));


   return cell;
   }
}

Alternately you can use a custom column implementation like the 
FragrementColumn and add the onclick when the cell is created like:


class MyOnClickColumn extends AbstractColumn {
...
public void populateItem(Item cellItem, String componentId, IModel rowModel)
   {
  Label cell = new Label(componentId, new PropertyModel(rowModel, 
property))


   cell.add (new AttributeAppender(onclick, new Model 
(someJavascriptCall();));


   cellItem.add(cell);
   }
}


I think the second version would attach the onclick to the label within 
the td/td of a cell.


Regards,

Mike

I dont know wicketopia project (and any of its classes like FragmentColumn)
so I can misunderstand your idea but as far as I am able to read that code
It looks like you are adding a link to the table cell, not making a cell
itself a link.

If I understand your code it is familar to:

tdlt;agt;textlt;/agt;/td

but Im wondering how to achive:
td on click=xyztext/td

where xyz is code generated by Wicket (like in Link component class)

If I misundestood you could you give me some more details hot to make cell
itself a link ? (not adding a link to the cell) ?

Regards 
Daniel

although my html file contains a head tag, and the javascript code

any idea?

Re: inserting javascript from java to html file

use iheadercontributor, that should work much better

also make sure your page has body tag.

Re: Serialization problem - detaching an oblect from session


the object negotiates between the user and a server that provides a messaging
service.
there is a new object for each user - thus it must sit in the session.
The object contains non serializable objects such as sockets and
httpRequests...

Re: inserting javascript from java to html file

huh? it did not create the fileyour javascript will be inlined!

you are using the onloadjavascript which needs support for the onload
event, which is why the wicket-event.js is included before your
javascript.

all this is apparent just by looking at the output code, you can see
your code being inlined...

Re: DataTable cell link


All this solutions are correct but the problem is not in attaching some
custom Javascript to td element (which can be done in multiple ways) but
in making td element work as a link.

What exactly should I do to achive this ? What components should I add at
server side at what JavaScript should I render at markup ? 
If I have to copy-paste bunch of Link class code it looks like some
design/implementation problem of DataTable (or one of components it has).

Its really supprising that such common issue is such problematic.
I hope there is some simple and intuitive solution(if I find one I'll post
it here)

Thanks for your help

 Hi Daniel,
 
 If you subclass DefaultDataTable there is a protected method call

 Item cell = super.newCellItem(id, index, model);
 
 
 cell.add(new AttributeAppender(onclick, new Model

 return cell;
 }
 }
 
 Alternately you can use a custom column implementation like the 
 FragrementColumn and add the onclick when the cell is created like:
 
 class MyOnClickColumn extends AbstractColumn {
 ...
 public void populateItem(Item cellItem, String componentId, IModel
 rowModel)
 {
Label cell = new Label(componentId, new PropertyModel(rowModel, 
 property))
 
 cell.add (new AttributeAppender(onclick, new Model 
 (someJavascriptCall();));
 
 cellItem.add(cell);
 }
 }
 
 
 I think the second version would attach the onclick to the label within 
 the td/td of a cell.

 It looks like you are adding a link to the table cell, not making a cell

 If I understand your code it is familar to:

Re: Serialization problem - detaching an oblect from session

you can keep those in your application object, or servlet-context if

so application.mapsessionid,object and when the session is destroyed
you remove it from the map.

Re: few (not only) AutoCompleteTextField questions


Textfields do recive onchange event, even AutocompleteTextField has modified
version off onchange event handler.
Whats more new AjaxFormComponentUpdatingBehavior(onchange){..}; works well
in this scenario but
OnChangeAjaxBehavior not. 
I looked at OnChangeAjaxBehavior implemenation and this is a subclass of
AjaxFormComponentUpdatingBehavior class with super(onchange); call in its
constructor. 
This class only provides its own implementation of onComponentRendered
method so there should be a problem. 
When I looked at OnChangeAjaxBehavior class contract description in JavaDoc
(A behavior that updates the hosting FormComponent via ajax when value of
the component is changed. This behavior uses best available method to track
changes on different types of form components.) there is no mention that it
shouldnt be used with some components so I think its bug either in
OnChangeAjaxBehavior class or AutocompleteTextField class.

Correct me if I'm wrong.

 Hi,

 First, problem description:
 Recently I was asked to change DropDownChoice field into
 AutoCompleteTextField.
 Everything was ok untill I noticed that old DropDownChoice field has
 attached OnChangeAjaxBehavior.
 Ofcourse what works well with DropDownChoice doesnt work as I want with
 AutoCompleteTextField.
 The problem is that I want to update a model after user selects one of
 choices(from autocomplete) not after any change of text field.
 I found getOnSelectJavascriptExpression method in
 AbstractAutoCompleteRenderer (since Wicket 1.4 ?) and I thought that it
 would be a good place to call some JS to update text field model.
 I looked at
 http://cwiki.apache.org/WICKET/calling-wicket-from-javascript.html to
 see
 how to call server side Wicket code from JavaScript.
 Next I had the idea to attach to text field
 AjaxFormComponentUpdatingBehavior and call its getCallbackUrl() from
 JavaScript returned from mentioned earlier
 getOnSelectJavascriptExpression().
 The problem is that AjaxFormComponentUpdatingBehavior expects event name
 in constructor  - in this case I dont need any onXXX event because I
 will
 call its getCallbackUrl() directly from JS.

 Now few questions:
 1)How to update (via Ajax) model of some FormComponents from JavaScript?
 Do I have to attach AjaxFormComponentUpdatingBehavior to some dummy
 event
 and call its getCallbackUrl() directly in JavaScript ? If so, its kind
 of
 hacking for me and AjaxFormComponentUpdatingBehavior should provide
 no-argument constructor.

 2)Does JavaScript returned from getOnSelectJavascriptExpression is
 called
 after corresponding TextField value has been set ?

 3)At Wicket wiki I found description how to work with
 AutoCompleteTextField and Models:
 http://cwiki.apache.org/WICKET/autocomplete-using-a-wicket-model.html
 I dont understand why this problem is not solved by subclassing directly
 form AutoCompleteTextField and overriding getConverter and provide some
 custom converter ?

 Ps. My colegue told me to attach AjaxFormComponentUpdatingBehavior to
 onBlur event, maybe this is the solution ? (but still, for me better
 place
 to update a model is in Javasript from getOnSelectJavascriptExpression()
 than in onblur event handler...)

 Best regards
 Daniel


 It was as simple as using a AjaxFormComponentUpdatingBehavior... I was
 confused because I started with OnChangeAjaxBehavior and it was broking
 AutoCompleteTextField - thats why I started thinking of diffrent
 approaches.

 BTW. Why AjaxFormComponentUpdatingBehavior works well with
 AutoCompleteTextField  and OnChangeAjaxBehavior doesnt ? Is it a bug in
 OnChangeAjaxBehavior or the purpose of this class is different ?

LoadableDetachableModel for drop-down menu selection

2008-10-28 Thread Gianni Doe

I'm starting out with Wicket and following the Wicket In Action  
examples through and I'm a bit stuck on how to make use of a  
LoadableDetachableModel in a drop-down menu situation.


I've got a drop-down menu of countries which is populated from a  
LoadableDetachableModel, this works perfectly but my selected Country  
is then stored in the page as a complete object, I'd like to be able  
to make use of LoadableDetachableModel also for the selectedCountry  
but I'm not clear on where and how I should instantiate it.

}
});

ChoiceRenderer locationRenderer = new  
ChoiceRenderer(description, id);

locationChoice = new DropDownChoiceLocation(

}
}

Re: DataTable cell link


Exaclty, problem is with 'consuming' td element by Item object.

The problem is that if you have wide column but short text in it some users
have problem with hitting the text (which is a link) .The idea is to make
whole td element 'clickable'(or linkable). 
The solution would be if table could have any component as row or cell
element not only Item object. 
But I know that this is a big change in DataTable class (or one of its child
component class) .

 Right, the td element is already consumed by the Item object, so you
 can't attach your link to it.
 
 What exactly should I do to achive this ? What components should I add at
 server side at what JavaScript should I render at markup ?
 If I have to copy-paste bunch of Link class code it looks like some

 Hi Daniel,

 If you subclass DefaultDataTable there is a protected method call
 newCellItem(...) that you can use to attach the onclick class onto the
 td.

 like:

 class MyDataTable extends DefaultDataTable {
  /* (non-Javadoc)
  * @see
 org.apache.wicket.extensions.markup.html.repeater.data.table.DataTable#newCellItem(java.lang.String,
 int, org.apache.wicket.model.IModel)
  */
 @Override
 protected Item newCellItem(String id, int index, IModel model) {


 Item cell = super.newCellItem(id, index, model);


 cell.add(new AttributeAppender(onclick, new Model
 (someJavascriptCall();));

 return cell;
 }
 }

 Alternately you can use a custom column implementation like the
 FragrementColumn and add the onclick when the cell is created like:

 class MyOnClickColumn extends AbstractColumn {
 ...
 public void populateItem(Item cellItem, String componentId, IModel
 rowModel)
 {
Label cell = new Label(componentId, new PropertyModel(rowModel,
 property))

 cell.add (new AttributeAppender(onclick, new Model
 (someJavascriptCall();));

 cellItem.add(cell);
 }
 }


 I think the second version would attach the onclick to the label within
 the td/td of a cell.

 Regards,

 Mike
 I dont know wicketopia project (and any of its classes like
 FragmentColumn)
 so I can misunderstand your idea but as far as I am able to read that
 code
 It looks like you are adding a link to the table cell, not making a
 cell
 itself a link.

 If I understand your code it is familar to:

 tdlt;agt;textlt;/agt;/td

 but Im wondering how to achive:
 td on click=xyztext/td

 where xyz is code generated by Wicket (like in Link component class)

 If I misundestood you could you give me some more details hot to make
 cell
 itself a link ? (not adding a link to the cell) ?

Re: DataTable cell link

Depending on what you are linking TO, it can be very simple.  You can call
urlFor(YourBookmarkablePage.class, pageParamsOrNullIfNone).  So, you could
do:

cellItem.add(new SimpleAttributeModifier(onclick, location.href = ' +
urlFor(YourBookmarkablePage.class, pageParamsOrNullIfNone) + '));

Of course, that JS could be better for triple click problems, etc.

Really, you may just consider using another Repeater rather than DataTable.
DataTable is for a very specific purpose, and it is often easier to roll
your own than make DT fit your purpose.

AbstractDefaultAjaxBehavior in a panel not working when loaded from an ajax context

2008-10-28 Thread adrienleroy


Hello,

I am trying to implements this JavaScript timedatepicker
http://labs.perifer.se/timedatepicker/ as an AbstractDefaultAjaxBehavior
here my class

public class TimePickBehavior extends AbstractDefaultAjaxBehavior {

private static final CompressedResourceReference TIMEPICKER_JS = new
CompressedResourceReference(
TimePickBehavior.class, resource/jquery.timePicker.js);
private static final CompressedResourceReference TIMEPICKER_CSS = new
CompressedResourceReference(
TimePickBehavior.class, resource/timePicker.css);
private String startHourMarkupId;
private String endHourMarkupId;

public TimePickBehavior(String startHourMarkupId, String
endHourMarkupId) {
this.startHourMarkupId = startHourMarkupId;
this.endHourMarkupId = endHourMarkupId;
}

@Override
public void renderHead(IHeaderResponse response) {
super.renderHead(response);
response.renderCSSReference(TIMEPICKER_CSS);
response.renderJavascriptReference(TIMEPICKER_JS);
String timePickerJS = jQuery(function() {;
timePickerJS += $(\# + startHourMarkupId + ,# + endHourMarkupId
+ \).timePicker();;
timePickerJS += var oldTime = $.timePicker(\# + startHourMarkupId
+ \).getTime();;
timePickerJS += $(\# + startHourMarkupId + \).change(function()
{;
timePickerJS += if ($(\# + endHourMarkupId + \).val()) {;
timePickerJS += var duration = ($.timePicker(\# + endHourMarkupId
+ \).getTime() - oldTime);;
timePickerJS += var time = $.timePicker(\# + startHourMarkupId +
\).getTime();;
timePickerJS += $.timePicker(\# + endHourMarkupId +
\).setTime(new Date(new Date(time.getTime() + duration)));;
timePickerJS += oldTime = time;;
timePickerJS += };
timePickerJS += });;
timePickerJS += $(\# + endHourMarkupId + \).change(function()
{;
timePickerJS += if($.timePicker(\# + startHourMarkupId +
\).getTime()  $.timePicker(this).getTime()) {;
timePickerJS += $(this).addClass(\error\);;
timePickerJS += };
timePickerJS += else {;
timePickerJS += $(this).removeClass(\error\);}});});;
//timePickerJS += //fin du script;
response.renderJavascript(timePickerJS,null);
}

@Override
protected void respond(AjaxRequestTarget arg0) {
throw new UnsupportedOperationException(Not supported yet.);
}
}

I have a page where i call a panel in ajax with this behaviour in it. In
that case the JavaScript is not working. But if i refresh the page it is
working.
In debug mode the JavaScript generated by this behaviour is between the
header-contribution encoding=wicket1  mark-up of the response. But it
seems unevaluated.

It seems to works in a none ajax context only.

I have tried different things to find where the problem is, but i am out of
ideas.

Thanks for any help

Re: DataTable cell link

If that's your problem, I'd suggest using CSS, something like:

TD A {
display: block;
}

This is much better because the anchor will fill the box (fixing your
problem), and you are more compatible (if JS is off, etc).

Meetings in the Netherlands (or neighbouring countries)

2008-10-28 Thread Harro Lissenberg

A colleague and I are getting more and more interested in Wicket and
where wondering if any meetings/presentations/lectures in or around
the Netherlands are being planned.
The community meetups page is rather out-of-date:

http://cwiki.apache.org/WICKET/community-meetups.html

So, anybody out there know of any meetings that might be worthwhile?

Feedback Panel on Modal Window With Field Validation does not work

2008-10-28 Thread sureshram


Hello,

  I am trying to add auto validation in the modal window but I don't see any
error messages. I added a feedback panel on a modal window which has a
required text field.  When I try to submit, the modal window does not do any
thing and I think what happens here is wicket does validation (which is
failing) and does not submit the form. It does not show error messages in
the feedbackpanel also.

public class AddAccountModalWindow extends ModalWindow {

public AddAccountModalWindow(String id) throws Exception {
super(id);
setInitialHeight(450);
setInitialWidth(500);

setTitle(Add New Account);
AddAccountContentPanel newAccPanel = new 
AddAccountContentPanel(content)
{   
private static final long serialVersionUID = 1L;

void onCancel(AjaxRequestTarget target) {
close(target);
}

};
setContent(newAccPanel);

};

}

public abstract class AddAccountContentPanel extends Panel {

public AddAccountContentPanel(String id) throws Exception {
Form accForm = new Form(accForm);
accForm.setOutputMarkupId(true);
setModel(new Model());
add(accForm);

feedbackPanel = new FeedbackPanel(feedback, new
ContainerFeedbackMessageFilter(accForm));
accForm.add(feedbackPanel);

TextField  accName = new TextField(accName, new
PropertyModel(clearingAccount, mnemonic));

   AjaxFallbackButton createAccount = new
AjaxFallbackButton(createAccount, accForm){
 protected void onSubmit(AjaxRequestTarget target,
Form form) {
//hidden code here.
 }
   }
  accForm.add(accName);
  accForm.add(createAccount);

}

}

Re: Forcing property models to update

2008-10-28 Thread walnutmon


I did as you said, and have the unit tests, and read the wiki on chaining
models... something still isn't clicking though.  BTW, I have Wicket in
action and it is fantastic, perhaps there is still something elduing me
though...  I still can't wrap my head around why that property model doesn't
update in the first case you show me.  If the property model is calling that
object, and doing a get description each time it's called it's own
getObject() method, why doesn't changing the reference externally work?

If you simply point me to a page number and tell me to read until I
understand, I would be greatful!

Thanks again!
Justin

 PropertyModel pm = new PropertyModel(s, description);
 assertEquals(I haven't read Wicket in Action but hear it helps solve

 This is basically what you are doing in your panel.
 
 but if you did:
 State s = new State(Foo);
 Model m = new Model();
 m.setObject(s);
 PropertyModel pm = new PropertyModel(m, description);
 assertEquals(Foo, pm.getObject());
 
 and now for the coup de grace:
 
 s = new State(Bar);
 m.setObject(s);
 assertEquals(Bar, pm.getObject());

 When I pass a news object into the panel on creation all of the form
 elements fill as expected.  However, if I set that object through a
 setter
 in the panel class, the elements do not update.  My theory (which may be
 wrong) is that the property model makes a defensive copy and therefore is

 If that's not true, any insight as to what I may be doing wrong?

Re: wicket and 508 compilance

2008-10-28 Thread Pointbreak

I don't understand why you keep insisting that a title attribute should
always be included in an anchor. In most cases the text within the
anchor tag is enough information for what the purpose of the link is,
certainly if you think a minute about that text. In such cases a title
attribute will just confuse users with an overload of unnecessary
information. Which by the way is especially irritating for users that
use screenreaders. Yes some accessibility guideline checkers will
generate warnings or errors if you omit the title tag, but what do they
know, they are just stupid programs.

Re: GMap2 - GInfoWindow

2008-10-28 Thread Martin Funk


Jeremy Thomerson wrote:
I'm not sure who maintains GMap2 (Martin F?) 

I guess one could say that :-)

- but I just created a class
that allows me to show an info window when a GMarker is clicked.  This could
actually be abstracted to allow other calls on a GMarker fairly easily.

Two questions:
1 - is there a better way already built in?  (I couldn't find one)
  

It's hard to say what way is better. Look at what we've done in
wicket.contrib.examples.gmap.top.HomePage
I think it pretty much implements the same as what you came up with.
But it does it in an ajax way, clicking a Marker sends an ajax call to 
the server, which generates what has to show up in the Infowindow and 
sends it back.
As I understand your code example the html for the InfoWindow has to be 
known by the time the marker is inserted in the map.

Which might suite your needs.


2 - can you use this class or a better method to include this functionality
in GMap2?
  
If you want your code to be preserved for others, come up with a patch 
for wicket-contrib-gmap2-examples.
And if you are desperate you could ask for commit rights on the 
userlist, and do it yourself.


Feel free  have fun,

Martin

Thanks for the GMap2 contribution!!

Wicket and URLs

2008-10-28 Thread S D


Hi,

I was browsing through examples, it looks very impressive but there's a thing 
that bothers me somewhat. The Basic Label example uses the following URL:

http://wicketstuff.org/wicket13/compref/;jsessionid=F8C6R0F2601C96D1Y3CAD8B69E8779D4?wicket:bookmarkablePage=:org.apache.wicket.examples.compref.LabelPage

The problem with that is that we'd like to have an appearance of a technology 
neutral site (or at least not to be blatant about it) but Jsessionid and 
especially 
wicket:bookmarkablePage=:org.apache.wicket.examples.compref.LabelPage 
destroy that impression completely.

I understand it's possible to remove Jsessionid from URL but what about 
Wicket's contribution to the URL? We'd like to keep our URLs as clean and

So, if I understand you correctly, I'd have to call mountBookmarkablePage() for 
all wicket URLs used in the application. Sounds somewhat tedious but should be 
doable.

No simpler way to achieve this?

Thanks

Re: Wicket and URLs

You can also mount all pages in a package with one single call.   You will
find this in old emails on the list, blogs, etc..

Google search for wicket mount package:
http://www.google.com/search?hl=enrls=com.microsoft%3A*q=wicket+bookmarkable+urls

The third result:
http://www.javalobby.org/java/forums/t68753.html

And in that page:
mount(/main, PackageName.forClass(AlohaPage.class));

Hope this helps!
