TreeTabel and file download
Hello list, I'm trying to implement small file browser and I use TreeTable. PropertyTreeColumn shows file names and I can get (newCell -> getTreeTable().getTreeState().isNodeSelected(node)) java.io.File. Now, I'm need force to download file after click on the file name. Any suggestions? Thanks, Anton - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
AjaxLazyLoadPanel and back button
I'm using the AjaxLazyLoadPanel to load images I'm generating from reports. When I'm on a page with the AjaxLazyLoadPanel, click a link to another page (like a BookmarkablePageLink) and then click back, the image that was generated is still in place. However, if I submit a form that's on the panel's page and then hit the back button, it goes back to the page with the spinning busy indicator and it spins forever, rather than displaying the already rendered image. Is this by design or should the generated image be rendered as it does when clicking a link? I'm using wicket 1.4.15. -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/AjaxLazyLoadPanel-and-back-button-tp3168379p3168379.html Sent from the Users forum mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
Re: radio group stated not updated via AJAX. Possible bug?
all components need that after they have been submitted once. how is
component to know that you have updated its model object? have you
called component.modelchanged()? clearinput() will do the same as
that.

Re: radio group stated not updated via AJAX. Possible bug?
Igor,
Thanks for your answer. Yes, I thought about that possibility but
somehow it seems weird to me that you have to call clearinput() to get
the component update its state based on the model value: in particular
because other form components do not need that trick to work properly.
Would the override
public boolean isInputNullable() {
return false;
}
have any other (undesirable) side effects? This "solution" has the
advantage that I can roll out my own AjaxUpdatebleRadioGroup and thus
I do not have remember to call clearinput() over and over.
Regards,
Ernesto

call clearinput() on the radiogroup so it refreshes based on new model
value you set.

Hi,
Apologies for the somewhat lengthy e-mail.
Consider the following situation
1-I have a form with a RadioGroup, several Radio buttons, an AJAX
submit button and some AJAX links that fetch "information" that can be
used to repaint the form and the RadioGroup.
In simplified code more or less this.
public class RadioPage extends WebPage {
private static final long serialVersionUID = 1L;
private WebMarkupContainer context;
private Gender gender;
private FeedbackPanel feedbackPanel;
public RadioPage() {
Form form = new Form("form");
add(form);
context = new WebMarkupContainer("context");
context.setOutputMarkupId(true);
form.add(context);
RadioGroup gender = new RadioGroup("gender",
new PropertyModel(this,"gender"));
gender.setRequired(true);
context.add(gender);
// hombre
Radio sexoH = new Radio("male", new
Model(Gender.MALE), gender);
gender.add(sexoH);
Radio sexoM = new Radio("female", new
Model(Gender.FEMALE), gender);
gender.add(sexoM);
add(new AjaxLink("makeMale") {
private static final long serialVersionUID = 1L;
@Override
public void onClick(AjaxRequestTarget target) {
RadioPage.this.gender = Gender.MALE;
if(target != null) {
target.addComponent(context);
}
}
});
add(new AjaxLink("makeFemale") {
private static final long serialVersionUID = 1L;
@Override
public void onClick(AjaxRequestTarget target) {
RadioPage.this.gender = Gender.FEMALE;
if(target != null) {
target.addComponent(context);
}
}
});
form.add(new AjaxSubmitLink("submit") {
private static final long serialVersionUID = 1L;
@Override
protected void onSubmit(AjaxRequestTarget target,
Form form) {
form.info("Gender was set to " +
RadioPage.this.gender);
target.addComponent(feedbackPanel);
}
@Override

}
});

Male

Updating RadioGroup via AJAX does not work:
Make male and Make female.
and
public enum Gender {
FEMALE,
MALE;
}
2-You click on the AJAX submit button without selecting any of the
radio buttons. This seems to set the rawinput of RadioGroup to null.
3-You click now on one of the AJAX links (Make male or Make female in
the example) in order to fetch the "information" and repaint the form
via AJAX. But radios checked condition is not updated:-(
This seems to be because of following code on Radio.onComponentTag():
// compare the model objects of the group and self, if
the same add the
// checked attribute, first check if there was a raw input on
the group.
if (group.hasRawInput())
{
String rawInput = group.getRawInput();
if (rawInput != null && rawInput.eq
