You should do the form submission on the server side - not actually forcing
the client to literally submit a form to their server. In other words, use
HttpClient or similar and make the POST request to chinabank's servers
yourself.

You haven't said anything about what payment solution you're using. The
thing is, if you have to redirect the user to the payment solution with the
pricing (or whatever your "important" param is) as a URL parameter, then
that will NOT be secured by putting it in JS. An intelligent user can just
as easily see the param there.

Re: Javascript from panel does not work
Please make sure that your JS files are loading. I suspect you may be getting a 404 when loading the JS because you are not referencing them correctly (you're using a relative URL, which may not work depending on where your panel is placed). Also, where is the JS that adds the onclick handler that highlights a row when it is clicked? I'm assuming it much be "ToggleHighLigh.js"? -- Jeremy Thomerson http://www.wickettraining.com On Tue, Apr 6, 2010 at 5:41 PM, Daniela Valero wrote: > Hi everybody > > I'm having a problem with my call to javascript from a panel.

Re: Display timeout page for long running requests
alternatively you can have a filter that adds the current thread to some background monitoring process which can, if needed, take over the request. you will need to play around with that and your container - eg test what happens if you interrupt a thread, etc. -igor On Tue, Apr 6, 2010 at 3:33 PM, Gerolf Seitz wrote: > you can use an ajax timer to check if the long running process has finished > after > 5 seconds and abort the process and redirect the user to the timeout page if > it hasn't. > > gerolf > > On Wed, Apr 7, 2010 at 12:11 AM, Mak wrote: > >> Hi All, >> I am new to wicket framework.

Re: ajaxfallback
before adding a component to the ajaxrequesttarget, simply check that the target is not null (aka the request is an ajax request). otherwise you don't need to add the components to the ajaxrequesttarget anyway. gerolf On Wed, Apr 7, 2010 at 12:20 AM, tubin gen wrote: > I am using AjaxLink all my application and we add to AjaxRequestTarget > for > repainting components , now we want to change it to use AjaxFallback , but > in ajaxfallback AjaxRequestTarget is null and I get null pointer > exception.Please tell me if there is any way I can move from AjaxLink to > AjaxFallBack link without breaking ? >
Re: Display timeout page for long running requests
you can use an ajax timer to check if the long running process has finished after 5 seconds and abort the process and redirect the user to the timeout page if it hasn't. gerolf On Wed, Apr 7, 2010 at 12:11 AM, Mak wrote: > Hi All, > I am new to wicket framework.

I am using AjaxLink all my application and we add to AjaxRequestTarget for repainting components , now we want to change it to use AjaxFallback , but in ajaxfallback AjaxRequestTarget is null and I get null pointer exception.Please tell me if there is any way I can move from AjaxLink to AjaxFallBack link without breaking ?
Display timeout page for long running requests
Hi All, I am new to wicket framework. I have a requirement that my wicket application needs to abandon its request processing after the specified time (say 5 secs ) has elapsed. Also, an error page / popup should be displayed after timeout to notify the user. In other words, from user point of view either we should get the correct output page before 5 seconds or display timeout page after 5 seconds. Any ideas/directions on how to implement this requirement would be highly appreciated!! Thanks Mak

RE: Build custom JavaScript
If the javascript will change often then it's probably best to include it directly into the of the page, otherwise it's just another HTTP request that probably won't be cachable. So to put something in the , you can try a StringHeaderContributor or implement IHeaderContributor. If you really want to use a file, I guess you could probably use JavaScriptResourceReference. The Resource itself would be WebResource or one of its subclasses and would return a StringResourceStream that wraps your generated JS. This is just a guess though since I haven't actually tried it.

Re: DataView, ReuseIfModelsEqualStrategy, Ajax
No - I mean use jQuery, YUI, or whatever you are currently using (or custom
JS that you write without one of these frameworks), and just add a CSS class
to the dom element on the client-side. There is no reason to make a
roundtrip to the server to simply change the CSS class. That wastes time
and resources, and makes the app less responsive.
Do something (jQuery code) like
onfocus="$(this).parent().addClass('highlightedfield');" to get started,
then onblur="$(this).parent().removeClass('highlightedfield');"

Re: DataView, ReuseIfModelsEqualStrategy, Ajax
Hi Jeremy, I'm doing something similar than Araun, but with
item.add(new AjaxEventBehavior("onclick") {
@Override
protected void onEvent(AjaxRequestTarget target) {
HighLitableDataItem hitem =
(HighLitableDataItem)item;
hitem.toggleHighlite();
target.addComponent(item);
}
});
But, when I click the item, it Highlites a few seconds, then turns back its
normal style.
Is that because you suggest do not do it with ajax?
Is there a way to do this, without rendering all page?
When you said "JS library and attach to onfocus.". Do you reference
JSLibrarie inside wicketStuff trunk?

RE: What happens after browser's 'back' b utton?
You're right James, I failed to mention that my approach will not work for
stateless pages. A stateful URL is needed to identify the previous page
instance. Regarding Firefox's lack of server trip on back button, this is what
I was getting at with the cache header stuff I mentioned. The WebPage class's
setHeaders method (in v1.4.1) looks like
protected void setHeaders(WebResponse response)
{
response.setHeader("Pragma", "no-cache");
response.setHeader("Cache-Control", "no-cache, max-age=0,
must-revalidate"); // no-store
}
The "// no-store" is actually there. Overriding it with
protected void setHeaders(WebResponse response)
{
response.setHeader("Pragma", "no-cache");
response.setHeader("Cache-Control", "no-cache, max-age=0,
must-revalidate, no-store");
}
Will cause firefox to make a trip to the server when back button is pressed.
In my experience this is required for AJAX & the back button, otherwise wicket
won't know that the user hit back and will ignore AJAX requests because they
are being executed against a page that (as far as wicket knows) is not the
active page.

Not exactly. How would Wicket know to pull the "old" page instance if
the browser is re-requesting a bookmarkable URL? It wouldn't. It
would just reconstruct the page from scratch. In fact, Firefox
doesn't re-request anything from Wicket when you click the back button
(at least it doesn't in my app when IE does, go figure). The way
Wicket keeps everything in synch is that each URL in your rendered
page (for forms, links, etc.) has information on it that "points" to a
specific page in the page map (that's what all the ?wicket:interface
stuff is). So, when a form is submitted or a link (non-bookmarkable)
is clicked on your page, Wicket will load the specific page instance
from the page map and invoke the request on that.

I totally agree with you here. I find JSR-303 to be a great standard that
addresses the validation problem very well, so having a minimal start point
inside wicket to use it would be a good idea.
Seeing as it is only 2 simple classes, and that the external dependencies
can be reduced to a minimum (just javax-validation-api), I proposed a RFE in
wickets jira: https://issues.apache.org/jira/browse/WICKET-2825 Vote for it

Re: DataView, ReuseIfModelsEqualStrategy, Ajax
Don't do this with AJAX - that's overkill. Just use a JS library and attach
to onfocus.

retrieve class value
Hello, It is pretty easy using SimpleAttributeModifier to set the class of a Label for example, but how to retrieve it ? My css classes due to lot of AjaxBehaviors change very often for a Label field and I would like to find the associated class before changing it ? thanks arnaud
Speaking about Wicket
Hi guys, I am organising a talk on Wicket at the end of April for the Java User Group Scotland. We expect about 20 people for our meeting in Edinburgh and are comparing the framework to GWT which was presented last month. I am posting to the list because I was wondering if anyone was in the area and would be happy to come and speak. If not I would still be interested in any useful material or tips for such a topic. Many thanks in advance for any responses, Andrew Williams Java User Group Scotland - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
Re: DataView, ReuseIfModelsEqualStrategy, Ajax
ok, find, so just do:
item.setOutputMarkupPlaceholderTag(true);
and
myTextField.add(new AjaxEventBehavior("onfocus") {
@Override
protected void onEvent(AjaxRequestTarget target)
{
item.add(new SimpleAttributeModifier("class",
"selected"));
target.addComponent(item);
}
});

Re: multiple feedback panels in same page
I just had this page with 2 forms issue - each form has some
RequiredTextFields, and some fields with custom StringValidators that I
didn't want to change from error to form.error.
This thread got me 90% of the way there, but
new FeedbackPanel("feedback", new *Container*FeedbackMessageFilter(myForm))
did the trick for my situation.
Just thought I'd mention it for benefit of fellow googlers in case they try
*Component*FeedbackMessageFilter and wonder where the messages went...

method error on construction time
Hi all,
I have a page when an error is thrown. This page is constructed in
MyCustomRequestCycle.onRuntimeException. This page is also use to send any
kind of message apart from errors. I add an
error("some error has occurred, please complete the form explaining what
happened ");
for error cases. But this message is not render in the page.
The cases I usually use for error messages are in the onClick and onError
methods.* But this is the first time I need an error message in construction
time. Why is not rendered?*
thanks in advance

RE: LoadableDetachable Models
Sorry; what I meant is that the value of the model is stored as a hard
reference. So this will work if your model is a string (person.firstName) but
the OP was concerned with manipulating a list of objects. The concern is if
your model's value is also a persistent object. For example a drop-down, to
select person.manager from a list; or a custom list control to set the value of
person.managerList, if person has 7 bosses (and has to hear about their
mistakes 7 times). The value of "manager" would be stored on the proxy (which
is a potential issue if the value of "manager" is a persistent person object).

It doesn't hold onto the persistent object. Here's an example usage:
IModel personModel = ...; // Some LDM here!
ProxyModelManager mgr = new ProxyModelManager();
add(new TextField("firstName", mgr.proxy(new
PropertyModel(personModel, "firstName";
Then, later on in the onSubmit() method, you'd call mgr.commit().
It's not going to hold onto the object that's loaded from the LDM. It
would hold onto the property values of the object that's loaded from
the LDM, but that's okay.

AW: Best Practices for Using JavaScript With Wicket
Hi Nishant,
you should use
component.setOutputMarkupId(true);
this tells wicket to generate a unique markup id. You can refer to the
generated id with
component.getMerkupId();
later.
If you want to add some javascript to your page, you may use two different
tricks:
A: Ajax-related
If you have an AjaxTrigger (e.g. an AjaxLink) do the following
AjaxLink() {
onClick(AjaxRequestTarget target) {
target.appendJavaScript();
// e.g. doSomethingWithDomelementWithId('"+
component.getmarkupId()+ "');
}
}
B. during page creation
If you want to bind some javascript during page creation/HTML render time try
this
Class MyPanel extends Panel {
...
@Override
public void renderHead(HtmlHeaderContainer container) {
container.getHeaderResponse().renderJavascriptReference();
container.getHeaderResponse().renderOnDomReadyJavascript("soSomethingWith('" +
getMarkupId() + "');");
}
}
And: Please have a look at the javadocs.
Stefan

Re: Forms in a base class
Hi All, I'm sorry if this is off-topic but I have a problem that's very similar and since you are talking about this here and seem to know what you're doing, I was thinking you might be able to help. I'm trying to create a basic form that all other forms in my project will extend, it's gonna have basic fields like name and description, and the rest (type specific fields) will be implemented by the children. however, my question is, does a form have an associated html file like a panel, or should all the children write the name and description fields in their respective markups? Now I saw that you're using a different methodology, which could maybe apply to my use case, but this method makes more sense to me but maybe it's not possible. just to reiterate, here's what I'm trying to do: Let's say i have 2 Pages A and B Now these both share a form that has a name and description field (and a specific ajax submit button and action) so page 1 will have a line like: add(new BaseForm()); and then we will add other fields to that form and the same will be in page 2 but the question is, will this form have an associated html? are we going to have to write the html with the name and description wicket fields on each page that has that form, or is there a way to generalize it? or should i just use the method defined in the thread above? -- View this message in context: http://old.nabble.com/Forms-in-a-base-class-tp27981164p28153812.html Sent from the Wicket - User 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

debugging traces in our code and the wicket code to help us understand
but that doesn't feel right..

Re: Properties of model are set to NULL even though we have setRequired set to true
Hi Nino,
we cannot reproduce it locally at all. Only happens in production.
we have a straight forward setup - apache balancing to 2 tomcat
instances - no clustering.
really annoying!

Re: Properties of model are set to NULL even though we have setRequired set to true
Hello Wayne,
I understand your frustration. Recently, I got a similar case but it eventually
turned out that it was my fault due to being new in Wicket. Long story short,
for a dropdownchoice list with loadabledetachablemodel, I set up a load method,
but in another place, I used dropdownchoice#setChoices to update the list for
ajax update. This method actually changes the model, but i did not know about
its impact. I spent almost a whole day to figure out why the load method did
not get called again.
So in your case, there MUST be a reason. Look everywhere these fields get
changed.
Good luck!
David

Re: Properties of model are set to NULL even though we have setRequired set to true
Hi Wayne
I guess you've tried debugging it, so it's not a consistent error? Are
you using any special web container or is wrapped somehow (like
terracotta)?

Build custom JavaScript
For my application I need to dynamically generate JavaScript, which can either be in its own file or even added to my HTML document. I'll handle the generation of the JavaScript, but does anyone have any good strategies for injecting it into a web page or even generating a JavaScript file with Wicket?

RE: root context, IE, home page is not found
Hi,
I use Glassfish v 2.1.1 with wicket 1.4.6 and in this version is redirect to
root changed form "./" to "."
(BookmarkablePageRequestTarget.respond(RequestCycle requestCycle)).
But I have still problem with this in IE(See attached picture).
When I send redirect with location finishing with "." IE will generate new
request with url also finishing with "." than IE receives redirect response
(it is not generated from wicket) with location "./" and we are at the same
point like in version wicket 1.4.3 where root context was represented by
"./" Result is the same 404 Page not found.
I used "/" for context root and it works fine in all browser. Why we are
using "." in wicket 1.4.6 or "./" in 1.4.3?
Thanks Dave.

How would Wicket know to pull the "old" page instance if the browser is re-requesting a bookmarkable URL? It wouldn't. It would just reconstruct the page from scratch. In fact, Firefox doesn't re-request anything from Wicket when you click the back button (at least it doesn't in my app when IE does, go figure). The way Wicket keeps everything in synch is that each URL in your rendered page (for forms, links, etc.) has information on it that "points" to a specific page in the page map (that's what all the ?wicket:interface stuff is). So, when a form is submitted or a link (non-bookmarkable) is clicked on your page, Wicket will load the specific page instance from the page map and invoke the request on that. - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
Re: What happens after browser's 'back' but ton?
As long as you prevent the browser from caching the page with the form (just
the page itself, caching the resources is fine) then when the user hits back
wicket will pull the old page instance from the pagemap and rerender it. That
page instance is the same one that was used the first time, so its state will
still be the same. Just set some flag when the user submits, and also check
that flag when processing the form like this:
onSubmit(...) {
if (!submitted) {
submitted = true;
// do some stuff
} else {
// redirect to another page
}
}
Wicket does set some cache headers, but to disable it in FF we had to set 1
extra header. If you check the setHeaders method in WebPage you'll see that
they set 3 headers I think and then there is one other header (must
revalidate?) that they have commented out. That commented header did the trick
for us. As for the redirect, you might be able to pull the 'last valid page'
as you call it from the page map, not sure though.

Wicket GAE performance
Hi Tony, I presume that you have studied the GAE/J documentation about datastore transactions at "http://code.google.com/intl/en/appengine/docs/java/datastore/transactions.html";. In particular, I note: "JDO performs all actions between the call to tx.begin() and the call to tx.commit() in a single transaction. If any action fails due to the requested entity group being in use by another process, JDO throws a JDODataStoreException or a JDOException, cause by a java.util.ConcurrentModificationException." In essence, let the JDO transaction do all the work for you! This should help you in the case where a maximum of one thread (= request) only is allowed to update persistent data at any time. All you will need to do then (apart from thinking though your design) is to handle the exceptions mentioned properly.

What happens after browser's 'back' button?
Hi, our first Wicket-based application is about to go into testing and I'm feeling rather uncomfortable about the fact that I don't really understand what happens when user uses browser's back button and then submits some 'outdated' form. Can someone elaborate please on what exactly happens when Wicket receives submit from the 'old' page? On a more specific note, I will most probably need to block user from submitting the same form more than once. E.g.: - If I wanted to prevent user from using back button at all, how would I determine that the incoming submit is from the 'old' page? - If I determined that Wicket received submit from the 'old' page, how would I send user back to the last 'valid' page they were on? - If I wanted to detect that user submits the same form twice (without necessarily blocking the back button in all cases), how would I go about it?

Re: Wicket GAE performance
Thank you very much, Ian, you clarified some things to me. I'm trying to block some entity got for processing by one session from other possibly concurrent session. I know what i would do if it were RDBMS: lock my object with "FOR UPDATE", if success, i would check if status field is still what i assume it must be and then update it to new status. But i'm not sure yet how to do this in GAE. -- Tony On Tue, Apr 6, 2010 at 12:06 AM, Ian Marshall wrote: > > Hello Tony, > > > > Anton Veretennikov wrote: > > > > This is a transaction of every session? > > > > I believe that there is some pooling of at least one of > PersistenceManager[s] (PM[s]) and Transaction[s] (TX[s]).

Displaying HTML
Hi guys; I am using TinyMCE to created styled text and save it in the database. I want to display the same on for example a label, is there any component that displays the text as HTML , i mean i dont want to see the tags, i want to see some formatted text. Kind regards. Josh
DataView, ReuseIfModelsEqualStrategy, Ajax
Hello,
I have a simple DataView where each row has some labels and textfields. Each
time the user enter in a textfield I would like to highlight the selected
row. (The idea is to adapt the wicket stuff example (OIRPage.java) with an
AjaxFormComponentUpdatingBehavior("onfocus") instead of a simple Link)
The example in wicket stuff
(
http://wicketstuff.org/wicket/repeater/?wicket:bookmarkablePage=:org.apache.wicket.examples.repeater.OIRPage
)
shows how to highlight the selected row using ReuseIfModelsEqualStrategy
when the user click on a Link.
Using the AjaxFormComponentUpdatingBehavior with the "onfocus" event I try
to simulate the Link click but it does not work...
myTextField.add(new AjaxFormComponentUpdatingBehavior("onfocus") {
@Override
protected void onUpdate(AjaxRequestTarget target) {
HighlitableDataItem hitem =
(HighlitableDataItem) item;
hitem.toggleHighlite();
// target.addComponent( ??? don' know what to put
here, how to re-render the item)
}
});
Well, any idea
thanks
Arnaud
