Hello,
in my application I have a table with some custom toolbars. This table shows
some data from the database if the user clicks an ajax button. But if the user
clicks the button again, the table will be replaced by a new table with the new
data. Here an example:
target.add(page.get("table").replaceWith(getNewTable(newData)));
This works fine. :)
Now the problem. When the user clicks the ajax button again the ajax request
begins running, but the user is able to click one of toolbars of the shown
table. So I get an exception: the table.toolbar was not found. This is ok
because of the replacement with a new table. I want to disable the shown table
while the ajax request is running. If the request detaches the old table will
be replaced by the new table with enabled toolbars.
I tried to override the onEvent-method of my table. Here you can see the code:
@Override
public void onEvent(IEvent<?> event){
if(event.getPayload() instanceof AjaxRequestTarget){
AjaxRequestTarget actualRequestTaget =
(AjaxRequestTarget)event.getPayload();
actualRequestTaget.addListener(new
AjaxRequestTarget.AbstractListener(){
@Override
public void onBeforeRespond(Map<String,Component> map,
AjaxRequestTarget target) {
setEnabled(false);
}
@Override
public void onAfterRespond(Map<String,Component> map,
AjaxRequestTarget.IJavaScriptResponse response) {
setEnabled(true);
}
});
}
}
But this didn't work. I can click the toolbars while the request is running and
then I get the old excetion. The table will be disabled if the request has
finished.
Is there any possibility to realize it?
Mit freundlichen Grüßen
