AW: set table disabled while ajax request is running
The problem ist that the links in the table aren't ajax links. There are also
the navigation toolbar and the the headers toolbar which I want to disable
while the ajax request is running. The button which starts the ajax call isn't
in the table too.

You can use AjaxChannel with the same name for all Ajax buttons/links in the
table and with type ACTIVE.
This way only one Ajax request for this channel will be executed. All other
will be discarded.

Re: Form multipart exception on firefox : "xmlAsString is undefined"
I finally found that the problem occures because of a javascript decorator on my ajax links. I need to investigate but without my decorators, all works fine. I should look those decorators first ... :( Thanks for your help. -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/Form-multipart-exception-on-firefox-xmlAsString-is-undefined-tp4663577p4663592.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: Wicket-Bootstrap Question
In the init() method of your application class :
final BootstrapSettings settings = new BootstrapSettings();
//add theme (optional)
settings.setThemeProvider(new
SingleThemeProvider(BootswatchTheme.CERULEAN));
Bootstrap.install(this, settings);
In your page class :
@Override
public void renderHead(final IHeaderResponse response) {
super.renderHead(response);
Bootstrap.renderHead(response);
// font-awesome (optional)
response.render(CssHeaderItem.forReference(FontAwesomeCssReference.instance()));
}
Then you should have all the css and js needed in your page.

Gabriel.

Re: Why is getDisplayValue in getDisplayValue final?
I dont remember exactly, but I guess I did it four or five times. That is not much but know what each of these is a hidden fork of the original implementation. I wish I had written my custom annotation @WicketFork for these classes ;-) Bye, Oliver Am 08.01.14 10:07, schrieb Martin Grigorov: This is true. The good thing is that Wicket is open source and you can copy the class and modify it locally. If you want to remove the copied code later you will contact us and tell us your use case. This way we get some feedback from our users and improve either Wicket code or users' code :) How many times you had to copy code for this reason ? There are no many complains about this in the mailing lists or in Jira. Last few years we don't use 'final' as the in the early development of Wicket. But we cannot just go over the code and remove all finals. Some of them have to be final. But if the user gives us a good reason we will consider it.

AW: set table disabled while ajax request is running
It is nice to show additional text oder something like this, but I cant hide or
disable the shown table. So the user has still the possibility to click at one
of the toolbars, which will throw an exception.
Are there no other ways?

Re: Determine which submit buttons was pressed
Maybe I'm missing something but it seems to me that the submittingComponent parameter passed to process is just an anonymously generated class that implements IFormSubmitter. Although it is not null when process is called, it only gives me access to the form and whether or not default form processing is enabled. Is there someway that this can lead me to the button that triggered the submit? -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/Determine-which-submit-buttons-was-pressed-tp4663550p4663582.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: set table disabled while ajax request is running
Hi,
You may show a veil above the table to prevent clicking on elements during
the ajax call

Re: Form multipart exception on firefox : "xmlAsString is undefined"
Hi, Can you reproduce this in a quickstart app ? If YES then please attach it to a ticket in Jira. What OS do you use ?

Form multipart exception on firefox : "xmlAsString is undefined"
Hello, I have a wicket page with a form. The form has to be multipart because an upload file component can be added dynamically into the form by ajax. When this upload file component is added/removed from the form, a javacript error occurred sometimes on Firefox : "xmlAsString is undefined" The code failing is in wicket-ajax-jquery (Wicket6) in htmlToDomDocument method : "var xmlAsString = htmlDocument.body.outerText;" I don't understand multipart form mechanism but I have done some investigations : 'htmlToDomDocument' method is called only when multipart form "iframe" is in 'BackCompat' mode. On Firefox, empty iframes are in 'BackCompat' mode. So 'htmlToDomDocument ' can be called on Firefox. However, body.outerText is an IE/Webkit property , not a Firefox property. Thanks, Jean-Philippe
set table disabled while ajax request is running
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 map,
AjaxRequestTarget target) {
setEnabled(false);
}
@Override
public void onAfterRespond(Map 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?

StalePageException when AjaxFallbackLink opened in new tab
Hi, I've few AjaxFallbackLink links in my page [not versioned], when I try to right click on these link and use the "open in new tab" option, page gets opened in new tab and results a StalePageException, because render count doesn't match [verified this by debugging org.apache.wicket.core.request.handler.PageProvider.getStoredPage(int)], but it gets into a infinate loop of refresh [due to repeated StalePageException s]. Can one point me to how to fix this?
