Re: Ajax refresh component with initial setVisible(false)
This is my submitCommentPanel:
public SubmitCommentPanel(String id, final PostDomain postDomain,
final UserDomain userDomain) {
super(id);
this.setOutputMarkupId(true);
AjaxFallbackButton ajaxCommentSubmitButton = new AjaxFallbackButton(
"commentSubmitButton", commentForm) {
/**
*
*/
private static final long serialVersionUID = 1L;
@Override
public void onSubmit(AjaxRequestTarget target, final
Form form) {
/*
* Populating commentDomain instance for
submitting comment.
* This instance is then passed to
CommentService class
*/
if (target != null) {
try {
// some processing
} catch (Exception exception) {
error(exception.getMessage());
}
target.add(submitCommentFeedbackPanel);
*target.add(SubmitCommentPanel.this);*
}
}
};
* here, I am adding one more panel which should not be visible in a
situation ...
ShowCommentPanel showCommentPanel = new ShowCommentPanel(
"showCommentPanel", postDomain, userDomain);
showCommentPanel.setVisible(!postDomain.getCommentDomainList().isEmpty());
add(showCommentPanel);*
}
Now ShowCommentPanel is:
public ShowCommentPanel(final String id,
final PostDomain postDomain,
final UserDomain userDomain) {
super(id);
// TODO Auto-generated constructor stub
* @SuppressWarnings("rawtypes")
Label numberOfCommentLabel = new Label("numberOfCommentLabel",
new PropertyModel(postDomain,
"numberOfComments"));
add(numberOfCommentLabel);*
}
Now what is happening that when showCommentPanel visibility is initially
false but later becomes true after ajax refresh, even then
*numberOfCommentLabel * does not appear. I have to refresh the whole page to
make them appear. After that they refresh properly by ajax.

Did you add your component to the AjaxRequestTarget for update? target.add(ajaxPagingNavigator); ??

Refresh component 'ajax'
I normally use 'target.addComponent(someOtherComponent)' to refresh/rerender that HTML content. Are there other ways to render/reload that component? Also, we are using wicket version 1.4.13
Re: refresh component
do something like this ...
on the markup template
some text
on java
Label mySpan = new Label("mySpan", new AbstractReadonlyModel(){
public String getObject() {
return myUpdatedText ;
}
});
mySpan.setOutputMarkupId(true) ;
//on your ajax line
updateMyText();
ajaxRequestTarget.add(mySpan);

Re: refresh component
Hi there,
you have to add the span to the AjaxRequestTarget inside your links
"onClick"-method. Your span has to be a Wicket component, of course.
So if your HTML looks somewhat like this:
...
...
your Java has to look somewhat like this:
...
Label myLabel = new Label("myspan"); // The label / span you want to refresh
myLabel.setOutputMarkupId(true);
Link myLink = new Link("myLink") {
@Override
public void onClick(AjaxRequestTarget target) {
target.add(myLabel) // Add label to requestTarget to get it updated on click
});
...
Hope that helps.
Cheers,
Andy

Re: Ajax refresh component
Hello,
Your problem is that you calling setOutputMarkupId(true) on the wrong
panel (you are calling it on LawView page constructor where in fact it
should be called on the component
that is added to the ajax request target, LawPanel). Also I think the
updated panel has to replace the current instance in the page hierarchy
as well as being added to the ajax request target.
Your class could benefit from using model's in a more intelligent way.
Make the LawPanel detail panel work with an IModel model. Control
the visibility of the details panel based on if there is a Law object
present.
When an ajax link is clicked just update the model value of the details
panel with the selected Law object and add the existing LawPanel into
the AJAX request target. This will allow your link to still work when
it is just a normal link (the fallback case).
For example:
Assuming the details panel lawPanel is a private variable in the main class.
Assuming in the page constuctuor the lawPanel.setOutputMarkupId(true)
method was called.
public void populateItem(final Item item) {
AjaxFallbackLink link = new
AjaxFallbackLink("linkViewLaw") {
@Override
public void onClick(AjaxRequestTarget target) {
Law law = (Law) item.getModelObject();
lawPanel.setModelObject (law);
if(target != null) {
target.addComponent(lawPanel);
}
}

Hi,
I've been searching the archives on a simple way to repaint a

The usecase:

2. Presses save (could be a wicket component)
3. An ajax-call is made to update a datasource (non wicket call)
4. Success-handler should repaint a wicket component
In 2 I tried with an AjaxButton and
requestTarget.prependJavascript("doAjaxSaveInOtherLibrary()")..
The problem with that is the timing. The prepended javascript function
returns and then the wicket ajaxcall gets executed before the
success-handler in the non wicket library...
I guess what I'm looking for is a simple way to add a markupcontainer
with an AbstractDefaultAjaxBehavior that I can reference from my non
wicket javascript.
Hi Mats,
how about this (pseudo code):
componentYouWantToPressOnForSave.add(new AjaxEventBehavior("onclick")
{
protected CharSequence getCallbackScript(boolean
onlyTargetActivePage)
{
return
generateCallbackScript("doAjaxSaveInOtherLibrary('" +
getCallbackUrl(onlyTargetActivePage) +
"'");
}
);
than you can decide if you want to initiate the AjaxCall to the
AjaxEventBehavior or not.
Just call
wicketAjaxGet(callbackUrl)
somewhere in your JavaScript on success-handler.

Re: How to refresh component many times in one ajax request
it should work fine.
A self updating timer only works once.. as far as i know
then it does the call. And the SelfUpdating add its component back to the
ajax request target
so that normally the timer is inserted again and started when the ajax
request finishes.
and the isEnabled() is checked when the component renders its behaviors.

Nope
thats already done:

*if* (behavior *instanceof* IHeaderContributor &&
isBehaviorAccepted(behavior))

Re: How to refresh component many times in one ajax request
I'm not entirely sure isEnabled() works properly on timer behaviors.
If it doesn't please add a feature request, the current implementation
is way too simplistic and needs to be enhanced.

I must do something wrong becouse it doesn't start refreshing.
My refreshing label:
counterLabel.add(new
AjaxSelfUpdatingTimerBehavior(Duration.seconds(2)) {
@Override
protected void onPostProcessTarget(AjaxRequestTarget
target) {
if (counter == 0 && confirmed) {
window.close(target);
}
}
@Override
public boolean isEnabled(Component component) {
return confirmed;
}
});
counterLabel.setOutputMarkupId(true);
add(counterLabel);
My confirm button:
form.add(new IndicatingAjaxButton("confirmButton", form) {
@Override
protected void onSubmit(final AjaxRequestTarget target,
Form form) {
confirmed = true;
setEnabled(false);
setOutputMarkupId(true);
new Thread() {
public void run() {
//do something here
counter--;
}
}.start();
target.addComponent(this);
target.addComponent(counterLabel);
}

Re: How to refresh component many times in one ajax request
AjaxSelfUpdatingTimerBehavior implements IBehavior interface, which has the following method: boolean isEnabled(Component component); Override it and provide your business logic there. Alex.

There is no enable/disable method in the AjaxSelfUpdatingTimerBehavior.

I think that the better approach would be to enable/disable the behavior, instead of adding it. Alex.

Thanks for reply Guys! My business case is much more complicated. This was
just simple example.
I did like you said. It was interested that I had to start new thread to
process the loop.
Without it the label didn't refresh the counter value.
Here is my code, maybe it would be helpful for someone else:
this.counter = 100
final Label counterLabel = new Label("counter", new
PropertyModel(this,
"counter"));
counterLabel.add(new
AjaxSelfUpdatingTimerBehavior(Duration.seconds(3)) {
@Override
protected void onPostProcessTarget(AjaxRequestTarget
target) {
if (counter == 0) {
//close the window after countdown :)
window.close(target);
}
}
});
counterLabel.setOutputMarkupId(true);
add(counterLabel);
Form form = new Form("form");
add(form);
form.add(new IndicatingAjaxButton("confirmButton", form) {
@Override
protected void onSubmit(final AjaxRequestTarget target,
Form form) {
setEnabled(false);
setOutputMarkupId(true);
target.addComponent(this);
new Thread() {
public void run() {
for (int i = 0; i < 100; i++
) {
synchronized (this) {
//do business
here ;)
try {
wait(300); } catch (InterruptedException e) {
e.printStackTrace(); }
counter--;
}
}
}
}.start();
}
});
Btw, is is possible to add Behavior to the component in the
AjaxRequestTarget?
For exampel I want to add AjaxSelfUpdatingTimerBehavior but when the user
click on the button.
Thanks,
Artur

Re: How to refresh component many times in one ajax request
What you're doing right now is to send a request to the server, iterate a
hundred times, replace a component a hundred times, even before the response
from the server reaches the client again.
That what you want to achieve would involve 100 ajax requests and responses,
it IS feasable, but better try a javascript-solution, because 100 roundtrips
is just too much if it's just for changing the label to a fixed value.
But if it's more than that, AjaxSelfUpdatingBehavior might be your friend

How to refresh component many times in one ajax request
Hi!
I try to do something like this
final Label counterLabel = new Label("counter", new
PropertyModel(this,
"counter"));
counterLabel.setOutputMarkupId(true);
add(counterLabel);
Form form = new Form("form");
add(form);
form.add(new AjaxButton("confirmButton") {
@Override
protected void onSubmit(AjaxRequestTarget target, Form
form) {
for (int i=0; i <100; i++ ) {
synchronized (this) {
try {
wait(1000);
} catch (InterruptedException
e) {
e.printStackTrace();
}
counter += i;
target.addComponent(counterLabel);
}
}
}
});
The component doesn't refresh. Only for the last time. How to make it work?
Thanks,
Artur
