something like that.

 Hello everyone,

 I use a NonCachingImage component to show an image in a form. The image
 shows correctly when using the Google App Engine for Java (GAE/J)
 development application server but fails to show when the code is running
 on Google App Engine (GAE) proper.

 I believe that this may be due to the image's src tag not being
 interpreted by GAE's cloud, whereas it is rendered properly by the dev app
 server.

 Has anyone had this happening to them? Can anyone think of a solution or
 suggestion? (Can I remove the src attribute?)

please, note that wicket-users forum is plenty full of examples like

as suggested before, may you add onchangeajaxbehaviour to your

java:

@SuppressWarnings(serial)
public class DropDownChoicePage extends WebPage {

private Entity selected;

public DropDownChoicePage() {

ListEntity list = Arrays.asList(new Entity[] { new 
Entity(coco),
new Entity(liso), new Entity(pata), new Entity(tero) });

DropDownChoiceEntity select = new 
DropDownChoiceEntity(select,
new PropertyModelEntity(this, selected), list);
select.setNullValid(true);
select.add(new OnChangeAjaxBehavior() {

 Hi Igor,

 Thanks for the reply!

 the usecase is simple, one requesthandler handing work off to another
 one. an easy example is a request handler that handles a callback
 (such as a link being clicked) scheduling the handler that renders the
 page after it handled the click.

 Yes, it is very common for one request handler *scheduling* another
 to be executed after its own execution. However, I am referring to
 one request handling *executing* another during its own execution.

why does this need framework support? simply call respond() yourself
if thats what you need.

 all scheduled handlers go into a queue and are executed in order.
 usually there are only two handlers scheduled - event handler and page
 renderer.

 The code shows that the scheduled handler is stored into the single
 scheduledAfterCurrent field in RequestHandlerStack, while the
 requestHandlers linked-list is not really used. The only location
 a request handler is added to the linked-list is in the execute()
 method, but it is immediately removed after its execution.

i guess thats there to support embedded execution which is not exposed
to the request cycle because there is no need for it. it may just be
that this code needs to be cleaned up since the usecase is no longer
needed.

Redirect to External Application

2011-10-17 Thread martin.dilger
Hi,

we have the following use case - we need to redirect to an external
application, that handles authorization for us (cookie creation etc.).

For this, we need to redirect to this application and handle a callback url,
where this external application redirects after succesful login.

I tried the following (very simplified, but worked in 1.4 but not in 1.5):

String url =
((HttpServletRequest)RequestCycle.get().getRequest().getContainerRequest()).getRequestURL().toString();
throw new
RedirectToUrlException(http://someexternalapplication?jumpBackToMyApplicationURL=+url);

In 1.5 I get 404 - since this url looks like this:
http://localhost:8080/wicket/page, which is not a legal url, since the page
identifier is missing.

I would love to hear some thoughts, how to handle this in 1.5, 
thank you very much.

RE: Efficiency of 1.5 MountMapper weighted/matching algorithm

2011-10-17 Thread Chris Colman
We have already discussed this problem before.

Cool!

Topicus' (Martijn's daily job) biggest application have ~ 700 mounted
pages and this code is not a hotspot for them, that's why no one spend

Wow that's big! If you had a variety of main and side bar menus on each page 
that had links to say 40 or so Bookmarkable pages that would mean each page 
render would result in building 40 weight/mount pair collections, each with 700 
entries - and then throwing them away after each bookmarkable page link has 
been created.

I realize it may not be a hotspot but, intuitively at least, it sounds like 
your new caching improvement will help reduce CPU load. It should also reduce 
the workload of the garbage collector by not having, in the above example, 2800 
objects allocated and then dereferenced with every page render.

Martin Grigorov-4 wrote:
 
 What do you think?
 I think this problem deserves a ticket to be discussed in more details.
 

I'd like to see this resolved for the dynamic image case.  Example use case:
1. I have a form that I'd like to re-use between two roles - Admin and
Read-only User. That is, the form is enabled for an Admin (full
permission to change things) and disabled for a Read-only User (not
allowed to change anything). 
2. The form allows for an ID text field to be changed, which seeds the
generation of a dynamic image to be displayed within the form next to the
text field.
3. Both roles should be allowed to see the image (i.e. regardless of whether
the parent form is enabled).

Pre-Wicket 1.5.1 (was on 1.4.9), this was never an issue for dynamic images
- i.e. images still appeared within disabled forms. 

Has anyone raised a ticket for this already?  And/or perhaps can offer a
workaround?

Eric is learning how to use Wicket and enjoying the experience so far...
