Re[2]: Alternative to Wicket data binding

2007-08-26 Thread Oleg Taranenko





Hi Igor and Eelco,

Sorry, for interventing in your discussion :)

May java annotations can help us?

Say [EMAIL PROTECTED]/Write
or [EMAIL PROTECTED] or ever to protect all bean.

It would protect the field from accidently access in Wicket models
without any assumption on set/get functions.

How it lead to additional lag on processing the model, i can't estimate.

Cheers,

Oleg

2007-08-26 Thread Matej Knopp



 For the sake of clarity, I think this:

 with public getXXX and private setXXX the property is read only
 with public getXXX and no setXXX the property is read only


So do I. I think it needs to be fixed. If there is a private setter, we
should use it. Period. Johaaan?!

 Hi

 I have a form that is submitted by ajax.

 I have validation on fields of the form.

 Using AjaxFormValidatingBehavior the form will be validated and error
 messages displayed when the onblur event is used.

 However this is not what I need as the validation of one field depends on
 another. I have tried to set the AjaxFormValidatingBehavior to onsubmit but
 it appears that if the form is invalid then its not submitted so no errors
 are displayed.

 Is there any way I can validate my form using ajax only when it is
 submited ?

RepeatingView : Removing a table row

2007-08-26 Thread pokkie


I have a RepeatingView that I generate, each row is represented as a
WebMarkupContainer. 
At the end of each row I add a checkbox. When the Delete Selected button
is called, 
I wish to remove the selected row from the RepeatingView and update the page
to reflect 
this status. 

--
WebMarkupContainer mainExerciseItem = new WebMarkupContainer(newChildId());

add(mainExerciseItem);

mainExerciseItem.add(new CheckBox(exerciseSelected, new
PropertyModel(mainMemberProgramExerciseHolder,
memberProgramExerciseSelected)));
--

Currently, I iterate over the items in the RepeatingView, check if they are
selected, and 
subsequently call remove(WebMarkupContainer). 

--
while (exerciseTable.iterator().hasNext()) {
WebMarkupContainer container = (WebMarkupContainer)
exerciseTable.iterator().next();
if
(container.get(exerciseSelected).getModelObjectAsString().equals(StaticData.TRUE))
{
exerciseTable.remove(container);
}
--

The problem is that it seems that after calling the remove() method, it
seems to be entering a loop and 
never returns. 

I have tried to call the render() method, but haven't had any luck yet. 

Any help would be much appreciated

Re: Re[2]: Alternative to Wicket data binding

2007-08-26 Thread Igor Vaynberg

the processing impart would be nil because we cache a lot of the
information. however forcing wicket annotations on middle tier objects is
not a very good approach.

if people really wanted to do this they can create this kind of annotation
themselves and then install a security manager that would check it.

i really dont think this is breaking encapsulation. i will concede that
there is one case where it can break encapsulation and that is when you
start out with what is publically accessible and then later you change your
mind and make it completely private, but forget to remap the property model.
it is a case where it is easy to make the mistake of not updating property
models. all other cases i believe are unimportant because you would have to
go poke around the class to even know that private field is there to start
with.

  all i asked johan to do was to tweak property resolver to allow access to

  tries to access the getter/setter first, then the field.



  half of this thread you are arguing that we shouldnt allow access to 
  private


  fields/methods and half of it you are arguing that we should but try the

  getter first, so im pretty confused.


  No, again, I'm arguing to *either* allowing access to all private, or

  don't allow it at all. I am not against private member access per se,

  just want it to be consistent.

Re: RepeatingView : Removing a table row

Hi,

it worked fine for me, I attach my own code so you can compare. Btw, why
don't you just use a listview with a model that filters out the selected
items? Imo it's simpler and more elegant. And another remark: you can bind
your checkbox to a boolean (see my example).

And now that I *really* look at this

WebMarkupContainer container = (WebMarkupContainer)
exerciseTable.iterator().next();
if (container.get
(exerciseSelected).getModelObjectAsString().equals(StaticData.TRUE)) {

}

you should be removing items from you collection while iterating over it
with the iterator's own remove, not the collection's one.

Do you tell Wicket to re-render whatever you have in place for error

If you have a cancel button for instance, you would do

Dynamically created popup window, IE7 wicket 1.3

2007-08-26 Thread Wilko Hische


Hi,

For a chat application I would like to display a list of chat requests that
have come in.
This list is updated by making use of an AbstractAjaxTimerBehavior.

When the user clicks a chat request in the list, a popup window will open
containing that particular chat conversation. In FF all works fine.

The unfortunate thing is that whatever I try, in IE7, the window containing
the list will become the active window whenever the timer fires, thus hiding
the popup window.

Even more strange:

- If the popup was started from a static (ie non dynamically updated)
element the popup doesn't lose focus.

- In wicket 1.2.6 it works fine.

I have been trying various approaches, for instance my own little Java
script creating the popup links, but for some reason I just can't get it to
work. I am willing to accept that is another IE7 feature , but that
doesn't help me much.

I am not really comfortable with Javascript, so before I dive into the
Javascript differences between Wicket version 1.2.6 and 1.3.x I would like
to ask whether somebody on this list might have some suggestions.

I have attached the Index.html and Index.java for the current 1.3 snapshot.
In 1.2.6 it works (mutatis mutandis).

Regards,

Wilko Hische

From what I can see AjaxFormComponentUpdateingBehaviour does not help.

It appears that the only way to do this is to not use component validation but 
to write my own validation in the submit processing code.

Not the most maintainable of solutions :(

Re: AJAX form submit and validation

2007-08-26 Thread Ian Godman

I worked it out. Very simple solution!

On the AjaxSubmitLink override the onError method and add the feedback panel to 
the AjaxRequestTarget !

 Thanks but this does not solve my problem.

 I am submitting the form via ajax using an AjaxSubmitLink. If the form has
 errors on it then I do not get the submit, if the form has no errors then
 the submit code runs ok. The errors are not displayed.

 If I add a AjaxFormValidatingBehavior for the onblur event then I can see
 the errors but they check for required fields etc as soon as the first field
 is left therefore displaying errors too soon.

 With the AjaxFormValidatingBehavior set to onsubmit event I get no error
 reporting and no submit.

 I need to validate the entire form only when submit button is pressed
 pressed. One possibility is to do the validation by hand in the submit
 processing code.

Re: Markup of type 'html' for component 'wicket.contrib.gmap.GMap2' not found

2007-08-26 Thread Martin Funk


Hi Hung,

this addition to the pom.xml of
   groupIdorg.wicketstuff/groupId
   artifactIdwicket-contrib-gmap2-examples/artifactId

should not be needed since that pom inherits that setting form
the pom.xml of
   groupIdorg.apache.wicket/groupId
   artifactIdwicket-parent/artifactId
   version1.3.0-SNAPSHOT/version

All that should need to be done after checking the project out using svn is:

mvn eclipce:eclipes

or

mvn eclipse:clean eclipse:eclipse
if, for whatever reason, a '.project' file is already present.

After that should be importable into an eclispse workspace, as an 
eclipse project.

DataTable with DropDownChoice to set rowsPerPage

2007-08-26 Thread Jerry Anders

I would like to be able to add a dropdown to a DataTable so that a user can 
change the rowsPerPage.  Has anyone done this before?  If not, what is the best 
/ recommended approach?
I tried the following, but I get:

IllegalStateException: Attempt to set model object on null model of component: 
rowsFINALDataTable contacts = NEWDataTable(contacts, columns, 
contactProvider, rowsPerPage) {
@Override
PROTECTEDItem newRowItem(String id, INTindex, IModel model) {
RETURNNEWOddEvenItem(id, index, model);
}
};

List rows = Arrays._asList_(NEWString[] {5, 10, 15, 20, all});
add(NEWDropDownChoice(rows, rows) {
@Override
PROTECTEDBOOLEANwantOnSelectionChangedNotifications() {
RETURNTRUE;
}
@Override
PROTECTEDVOIDonSelectionChanged(FINALObject newSelection) {
IF(newSelection == all) {
contacts.setRowsPerPage(10); // use really big number to 
display all
} ELSE{

});

The format of the Exception got munged with the example code. This should
read as:

final DataTable contacts = NEWDataTable(contacts, columns,
contactProvider, rowsPerPage) {
@Override

Yes, that or setDefaultFormProcessing(false) as Eelco suggested before.
That's not doing validation by hand, just postponing the moment of
validation to fit your needs. Then, when validation should be done, call
process() on the form and that will carry on validation and model updating
as usual. It's as simple as that.
