Hi all,
I have a Page with a DropDown Component and a Panel. The Panel displays
some stuff based on the model object of the DropDown.
In the constructor of my page, I set panel.setVisible(false) to prevent
the panel from being rendered while the model object of the DropDown is
null because the user has not yet selected an option.
Now I want the Panel to be rendered once a valid choice is selected by
the user. I tried this:
protected void onEvent(AjaxRequestTarget target) {
log.debug("ddMonth onChange triggered.");
if(month != null) {
reportPanel.setVisible(true);
reportPanel.updatePanel(getServiceManager(),
getUser(), month);
target.addComponent(reportPanel);
}
}
The event is triggered, the panel is not rendered though. Is there a way
to achieve this without reloading the entire page?
If not, how would I trigger a page reload from the onEvent method?
Thanks,
Stephan
