Re: [Wicket-user] CheckGroupSelector with CheckBox

2006-12-31 Thread TH Lim


Hi,

I have a similar situation where I have CheckGroupSelector to select /
unselect all checkboxes in the list view. I have overrided
CheckGroup.wantOnSelectionChangedNotifications() to return true. Therefore,
checking and unchecking each checkboxes sends an AJAX respond back to the
server. However, if I check on the CheckGroupSelector to check / uncheck all
the checkboxes there is no AJAX respond sent and CheckGroup is not updated.
How do I make the CheckGroupSelector to send an AJAX respond so that the
selection in CheckGroup reflects the selection on the web front? Thanks.

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
 choice, that means the one selected object out of that list - of type enum
 -
 will be set into the model object.
 
 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

Re: [Wicket-user] CheckGroupSelector with CheckBox

2006-12-31 Thread Igor Vaynberg


actually when you override wantonselectionchangednotification() it is not an
ajax request, it is a regular request that repaints the page.

checkgroupselector was made to select checkboxes on the clientside only
exclusively, if you want to do it via a roundtrip it is actually simple

add a checkbox with wantonselectionchangednotification() set to true, and in
the handler add all the possible model objects into the collection that
controls the checkgroup, so when the page repaints next all checkboxes will
be selected for you

Re: [Wicket-user] Update ListView via AJAX

2006-12-31 Thread August Detlefsen

Actually, this approach did not work for me -The container updated every 
5 seconds, but the list of items generated from the database never changed.

After some digging through the wicket sources, I solved this by 
overriding the onAttach() method of WebMarkupContainer to remove the 
list and regenerate it from the DB on each rendering:



public class AjaxContainer extends WebMarkupContainer {

protected void onAttach() {
removeAll();

ListView comments = new ListView(comments, commentList) {

protected void populateItem(final ListItem listItem) {

...


Do you forsee any problems with this approach?

Regards,
August

Re: [Wicket-user] Update ListView via AJAX

2006-12-31 Thread Igor Vaynberg


the list did not refresh because you did not specify a model that can update
itself across requests on the listview.

the listview should use a detachable model, try a LoadableDetachableModel

[Wicket-user] brave cavity

2006-12-31 Thread Marshall


Since the collapse of the Soviet Union and the end of the old world order of 
the Twentieth Century, this process has quickened considerably. 'There is the 
tendency to believe that the threat is receding and this war is coming to a 
close,' he said. Questioned on the source of the disinformation campaign, 
Government representatives have been curt and dismissive.
But the ugly phenomenon of commercial propaganda between SBS programmes has 
already given newly contemptuous viewers a reason to turn off.
Commentators keen to turn to more substantial have instead found themselves 
discussing Ministerial comment on the extent of the dangerous disinformation's 
spread. Stories from the network's flagship programme Dateline should not be 
missed but are available online.
The war on terror may get us all killed, say our capable leaders,  statesmen, 
and officials. But Downer has a partisan view of the ongoing conflict.
Commentators keen to turn to more substantial have instead found themselves 
discussing Ministerial comment on the extent of the dangerous disinformation's 
spread. Annans' proclamation, made from the Secretary-General's seat of power 
in the United Nations building in New York, was screened live around millions 
of worlds.
But the attempts of the anti-nuclear lobby to spin a nightmarish tale from the 
incident have proved fruitless, with the nuclear accident in actuality nothing 
more than a red herring. Israel's abundantly aggressive reaction to the 
slightest sign of military competence from its adversaries  has itself been an 
obstacle to peace. But  it is certainly less dangerous than NOT arming 
ourselves to the eye teeth and climbing out of helicopters half a world a way, 
guns blazing, in order to take down a few of the locals.
