Hello to y'all,
I'm facing a nasty problem for a very simple requirement. In my application
a user can enter an application code for working with that application
(deployments and so on).
Now I want to add a button that opens a Wiki-documentation page for that
application in a new browser tab. The URL for the wiki-page is stored in the
same database table as is the application code. I implemented this at first
with an ExternalLink, but I want to show an information message if the URL
is not entered in the database.
I can't get that done with an ExternalLink, so I used a Link instead. Well,
that gives the possibility to display info messages, but then I have to open
the URL myself by something like:
public void onClick() {
String docRef = getRefFromDb();
if (docRef == null) {
info("Please supply wiki-url first");
return;
}
RedirectRequestHandler redirectRequestHandler = new
RedirectRequestHandler(docRef);
RequestCycle.get().scheduleRequestHandlerAfterCurrent(redirectRequestHandler);
}
Obviously I leave my page when the link is clicked, so I added
onBeforeRender() in which I add PopupSettings if the url is found, so at
least I have a new window for the wiki-page (but I want a new tab). And if
not, I have to nullify the PopupSettings...
This is very awkward.
Please, anyone, a simple solution?
Btw, I'm (still) using Wicket 1.5.4.
Regards, Hans
