Very cool Anantha, do you have a site online that uses the bundler that we
could take a peek at as a running example?

Re: Page load after an action

[Riyad Kalla]

Stephane,

I'll let someone smarter than me address the wicket issue of removing the
item from the ListView and seeing if that helps -- but is there a chance you
are using Hibernate and the Level 2 ehcache plugin or any 2nd-level caching
with your persistence code? I ask because I've seen code like this "I don't
see my changes until the 2nd refresh!" a lot with folks using 2nd level
caches and not seeing immediate persistence of those changes.

Re: Page load after an action

[Riyad Kalla]

Seems weird to me as well that 'detach' has to be explicitly called. Also
still curious why Stephane was seeing the log ordering he did when the link
was clicked:


Loading all news
News deleted


I'd expect to see "news deleted" first, from his onClick handler then the
"loading all news" caused by the call to "load()" before the response was
sent -- in which case it seems he wouldn't have run into this issue in the
first place.

It's entirely possible I'm missing the wicket processing sequence here being
something else which would explain this.

Re: Image Bundler For Apache Wicket

[Riyad Kalla]

Just ran across another base64-based method of spriting images that
Cappuccino is using:
http://cappuccino.org/discuss/2009/11/11/just-one-file-with-cappuccino-0-8

pretty interesting and supports back to IE6. Just wanted to share incase
anyone else reading on this subject was curious about other techniques.

Igor, will FeedbackPanel correctly consume the messages from the session
scope and remove them -- or do you have to manually remove them once they've
been rendered?

Re: images not under the context root directory

[Riyad Kalla]

This seems like adding a large amount of overhead to an image-heavy site
(e.g. image blog or something), I thought I read in Wicket in Action that
WicketFilter ignored HTTP requests for non-wicket resources now and passed
them through to the underlying server to handle avoiding the need to remap
your wicket URLs to something like /app/* so you could have /images and
other resources under root and not have them go through the filter.

Is this not the case?

I have some pretty interesting stuff, like a BeanPanel that displays a
bean's properties in a nice looking key:value format, and another one
that allows you to upload a file, but is abstracted so you can upload
from a file on the local computer or from a web URL.

My most innovative one accepts a list of files as input, and
automatically generates zip/tar.gz/tar.bz2 archive downloads. I'm sure
these will come in useful to many. If anybody knows how to go about this

Re: Repeating View Horizontally

[Riyad Kalla]

Josh,

Just what Tor said -- repeaters will just repeat whatever markup you feed it
over and over again doing substitution on each one according to the backing
components. So just make sure you are repeating an element that flows right
to left -- a  or  -- probably a  is what you want (or heck,
even LI's that are styled like a menu to flow left to right would work, just
takes more CSS). Don't use  because they are block level elements and
won't flow the way (l > r) you want them to.

Best,
Riyad

Re: know the last page user comes from

[Riyad Kalla]

Martin,

It looks like you are trying to implement the flow for authorization
manually (User tries to go from PageA to PageB, but they require
authorization, so you temporarily send them to PageC -- if they fail, send
them back to PageA, if they succeed, send them to PageB).

The good news is that Wicket has nice support for denoting pages as
requiring authorization and then automatically walking users through an
auth-page and handling moving them forward or back for you if necessary.

Also you can checkout the wicket signin example:
http://wicketstuff.org/wicket14/signin/;jsessionid=1FF7784E87DBECFF9CF8624411BA0FA8?wicket:bookmarkablePage=:org.apache.wicket.examples.signin.SignIn

Re: images not under the context root directory

[Riyad Kalla]

Ernesto,

Sorry about that -- I didn't mean to imply your impl was back, that was more
directed at Francois along the lines of "that's a lot of overhead, are you
sure you need to do that?" -- but now that I understand what his use-case is
(saw his last reply about /usr/ext/img/) I get it. I was
thinking they were under /webapp/images.

I'll go back to sitting in my corner ;)

Re: Wicket Pattern to reduce session size

[Riyad Kalla]

Gaetan,

You can mark whatever instance that is causing the session to be so large as
'transient' to avoid it being serialized -- you'd have to recreate it each
time it was needed though. So if it's in your model:

=
private String chartName;
private String chartArguments; // maybe from a page param or something?
private transient DynamicImageResource chartImage; // won't get serialized
=

Re: AjaxFallbackDefaultDataTable and delete via ModalWindow

[Riyad Kalla]

Andreas,

This might be a dumb question, but are you sure at the point that the page
reloads and re-renders, the object *has* been erased from the database or
cache you are utilizing? For example, right after you delete, if you put in
some silly/junk code to immediately re-query for that object, it comes back
null right?

I'm sure this is an Ajax/model issue, but 1 time it took me 2 days trying to
figure out why something "Wasn't deleting" just to find out it was, but my
cache was deferring the operation to a few seconds later. So I figured I'd
throw that out there just incase.

Re: images not under the context root directory

[Riyad Kalla]

Matthew, this seems like a glassfish question... if you can "mount" local
system dirs in glassfish as web dirs, for example:
alternatedocroot_1 from=/uploads/*
dir=/Users/insane/path/under/netbeans/glassfish/domain1/uploads/Videos

would you access that content using http://www.mysite.com/uploads/*

Again, I'm not sure how that mounting rule in glassfish works, it might be
relative to your app root, but it seems it should work and just be treated
as a normal path -- in the case of the previous fellow I understood his
situation to be that he *had* to host resources out of a system directory
that wasn't web-addressable. I believe in your case they are web addressable
if that glassfish feature mounts them up as such?

Re: images not under the context root directory

[Riyad Kalla]

Good call -- going the intercept-and-stream route is great when you cannot
read from a web-addressable folder, but if you can do that, and can avoid
all that server-side processing by using a direct URL and just let the app
server do it's thing, then +1 on that.

Sounds like you got it going that way.

Re: nested forms onSubmit

[Riyad Kalla]

Are nested forms a valid HTML construct? I'm running through the use-case
here in my head and it doesn't click -- form submission is 1:1 with an HTTP
POST, what do multiple embedded forms even mean in this regard?

I don't think this is kosher...

Re: AjaxFallbackDefaultDataTable and delete via ModalWindow

[Riyad Kalla]

Andreas,

I'm glad you nailed down what was going on -- that being said, can you just
issue a .stop() on the timer on the first callback? So you get your 1
update, then the timer gets killed off and you are good to go?

Don't know that much about the Ajax Data Table, otherwise I would recommend
something way smarter :)

Re: Save a form's markup

[Riyad Kalla]

At first I thought you would override the Component.onRender method to see
what is going back to the client and save that, but iterating through the
MarkupElements looks expensive (to rebuild the page) and might leave the
response in an unexpected state. Also though you could possibly override
WicketFilter.doFilter call to try and snag the response on render, but then
realized searching for  HTML specifically is going to suck.

I then found this example on getting Wicket components to cough up their
HTML into a dummy output stream that you can do what you want with:
http://www.danwalmsley.com/2008/10/21/render-a-wicket-page-to-a-string-for-html-email/

THEN
I was reading on the Wicket Wiki (the WiWi if you will) about rendering
Panels to Strings, which is essentially what I think you want to do, and
found this:
http://cwiki.apache.org/WICKET/rendering-panel-to-a-string.html#RenderingPaneltoaString-renderpanelstring

--
I just included all the other resources incase they help with what you are
trying to do, wasn't clear on the use-case.

Have fun

Re: better look & modern css for wicket

[Riyad Kalla]

Shipping a few different custom themes as part of the Wicket SDK could be
interesting -- for the standard Wicket components that just back HTML4
elements it's a little less necessary I suppose, but for those custom
components, like Data Tables, making them look nice out of the box could be
a nice win. I suppose the same goes for some standard HTML widgets
(buttons?)

I wonder if there could be a Wicket 1.6 addition of a ThemeManager that all
wicket components could call into for "default" styles -- including the
custom components -- allowing artists to define well-known style names that
would get applied automatically and allow Wicket to ship themes out of the
box with it?

e.g. in Application.init() -- ThemeManager.setDefault("green-gloss.css")

As superficial as it is, we all know bling counts. If there is a huge demand
for making Wicket components look like an 1990s AOL webpage, I'll take the
lead on this... otherwise we should probably ask if anyone is a designer? :)

Re: How to simulate browser back button?

[Riyad Kalla]

JavaScript is your only option -- that should work in IE, that's some pretty
classic JavaScript right there.

If your IE install has JS turned off, I'm not aware of any other way to
programatically issue a 'back' to the browser.

Sorry I think my reply came across confusing -- I'm very green with Wicket,

use.

Re: Fix super(new CompoundPropertyModel(this)) error in the WIA book

[Riyad Kalla]

As someone working his way through WIA as well, will there be another wiki
entry showing differences between book and 1.5? (I'm fairly interested in
page mounting and nice URLs as well).

-- also I realize the cost to constantly maintain book diffs by the authors
is high, but just wanted to ask incase there were plans for it.

Re: Wicket best practice

[Riyad Kalla]

Vineet, very cool stuff you are wooing on. As for best practices with regard
to layout, there is actually a Maven Wicket archetype that would probably
answer those questions well. From what I remember its pretty straight
forward maven web layout. And yes, HTML and Java source are in same main
packages together.

On Feb 6, 2010 1:33 PM, "Vineet Manohar"  wrote:

Hi,

I am trying to write a code generator (using Clickframes code generation
framework) which would generate a fully working Wicket project directly from
the Spec. Is there a document which describes the best practice for
folder/package structure in a wicket project.

To write the code generator, the only thing I need to know is the Wicket
project structure that I should be created. For example:
1) should html files be colocated in src/main/java/com/mypackage/ along with
Java files (as in the helloworld example) or in src/main/webapp.
2) should there be one html file per page (I am assuming yes)
... and other such questions related to folder structure

I am the lead developer of open source code generation framework Clickframes
(http://www.clickframes.org) and have written a similar code generator for
JSF/Seam which instantly gives you a working app directly from the spec
which the developer can then customize. I think a similar approach for
Wicket would be very helpful to Wicket users who are trying to start a brand
new project.

Here's what I have so far.
http://code.google.com/p/clickframes-wicket-plugin/

I am a Wicket novice, so any help or direction is appreciated.

Thanks,

Re: TabbedPanel replaced by AjaxTabbedPanel shows request NS_BINDING_ABORTED

[Riyad Kalla]

Kulbhushan,

I think this is the result of Wicket using abort() calls on the
recycled XMLHttpRequest objects that are pooled as discussed here?

Re: Changes of html-files are not directly available - need to re-deploy

[Riyad Kalla]

Joachim,

Troubleshooting redeployment issues can be maddening. The *very first*
thing you have to rule out is that the file is actually getting placed
on disk in the deployed location. I don't know how NetBeans handles
it's deployments, if it points Tomcat at the internal project and runs
"in place" or if it actually copies out the project contents on-disk
to some deployed location.

Regardless, find the deployed location. Go change your HTML, save it,
then using a file explorer, go to the deployed location and manually
open the file that is in the deployed location (e.g. using Gedit on
Ubuntu) and confirm that those changes are in that HTML.

If they are, then the issue would be with Wicket polling and seeing
the changes and reloading them. If you don't see the changes, then the
issue is with NetBeans either not placing the files in the right
location or not being *Able to* place them -- i.e. a permission
problem (That running as root should have addressed).

NOTE: 1 last thing, I don't know how you are running Tomcat, but if
you are running it externally make sure it's running as the same user
as NetBeans. Othertiwse you could run into a silly situation of
NetBeans writing out files as "root" and Tomcat trying to read/load
the deployed files but not having read-perms on those "root-owned"
files.

Just want to avoid weirdness.

Re: Listening key pressings on server side

[Riyad Kalla]

Roland,

It might be the browser + event that you are listening for that is the
issue. Try onkeyup, here's a ref:
http://www.tutorialized.com/view/tutorial/Get-key-press-event-using-JavaScript/9689

or onkeydown:
http://www.dreamincode.net/code/snippet1246.htm

Otherwise I think you had the right idea at the beginning with where
to add the listener to, hopefully it's just the event that is the
issue.

Re: Example for Combobox wanted

[Riyad Kalla]

Nino,

I think what PDiefent wants is literally to re-create the Swing
combobox component, so something like:

[TEXT_FIELD][BUTTON]

and when you click [BUTTON] it causes a DIV to appear with a list of
choices, but the user can also type their own in.

PD, the only way I can think to do this is just to distill the issue
down to it's simplest components in Wicket and give it a go.




where I imagine dropdownButton would be an AjaxButton of some kind
that would set the visibility of the popupListBox when clicked.
popupListBox would be a ListView of some kind.

This is all just guess-work from my part, I haven't tried to build a
component like this before. Sorry.

Re: expecting different behavior from form validation - potential bug?

[Riyad Kalla]

Antoine,

I think this was discussed 3 days ago in the thread titled
"Form#anyComponentError change in 1.4 breaks validation" (Russel
Morrisey), basically noting that in a recent release of Wicket, the
form "onError" behavior was changed to checking for errors on ANY
component in the form, to just Form-based components.

Related JIRA Issues:
http://issues.apache.org/jira/browse/WICKET-2202
http://issues.apache.org/jira/browse/WICKET-2026

And eventually this issue created:
https://issues.apache.org/jira/browse/WICKET-2734


Hope that helps incase you wanted to jump in on any of that.

Re: add form components via ajax

[Riyad Kalla]

setMarkupId(true) is used to ensure there is a placeholder generated
in the HTML where the addition of the  (or whatever) will take
place.

You don't set this typically on the form itself, but on a placeholder
inside the form that you probably replace with a MarkupContainer of
some kind with the same name that contained the new form elements that
you wanted to inject.

I think you're exactly right to use the

MetaDataKey(example
code uses ROLE) it seems that was one of the intents.

Re: Scroll to Anchor on Form Submit

[Riyad Kalla]

Tony,

I'm not sure if you can mess with the URL (e.g. append a #errors) from
within Wicket without causing a redirect (and loosing your errors from the
request and form state) -- someone smarter than me can address that -- but
if you wanted to get creative, maybe in the onError handler your can
contribute a behavior of some 'window.onload' JavaScript to the body of the
page that does a 'window.location=#errors' or somethig like
that, so as soon as the page comes back up, the JS "redirects" to the exact
same page but an anchor on it.

Not sure if that would cause a redirect or not...

Re: OnChangeAjaxBehavior: nth character

[Riyad Kalla]

Vineet is exactly right, just to further flesh it out:

You want to add a subclass of AbstractDefaultAjaxBehavior to your page, this
automatically contributes the wicket-ajax.js file to your page which exposes
these JavaScript methods for you:

===
function wicketAjaxGet(url, successHandler, failureHandler, precondition,
channel)
and
function wicketAjaxPost(url, body, successHandler, failureHandler,
precondition, channel)
===

(paraphrased from Wiki)

The part I'm not clear on is which URL do you call with the JavaScript and
which method on the server side is intercepting the GET (or POST)?

That information seems to be missing from the wiki unless it's easier than I
realize and I'm overthinking this...

That depends on how much traffic your app gets. GAE isn't cheap if you start
getting serious traffic and depends on the services you tie into.

Re: Wicket used for mobile.walmart.com

[Riyad Kalla]

Joachim,

Very very cool info. A few days ago folks were talking about slides for
"convincing management of Wicket" and trying to create some common slides
for folks to utilize -- information like *this* (Walmart, Wells Fargo) is a
gold-mine for those business cases for Wicket.

Would it be alright with you if that info (that wicket was deployed on those
two mobile sites) were shared in that slide set or by people trying to make
cases for Wicket in their workplace? (I assume yes since this is a public
mailing list, but want to make sure)

Best,
Riyad

Re: [OT] Wicket App Hosting

[Riyad Kalla]

Slicehost or RimuHosting - support from both is excellent and immediately
accessible which I find invaluable given that when things are working,
almost any of the 150 VPS hosts out there are all the same.. it is when
stuff breaks that they differentiate themselves.

Best,
Riyad

Re: Model to use for static Label text

[Riyad Kalla]

Serban,

I really wouldn't trying and mess with detachable models unless you were
dealing with 100s of individual Strings that were climbing up beyond 4k each
or something like that -- if you are literally talking about UI labels, that
is so few bytes that leaving them static references is going to far
out-weigh the extra byte code written to try and manage loading them each
time they are needed, even if it's from something fast like a local
properties file.

As for your last question, I think the answer is "yes" -- a stateful page is
a page that maintains state -- some dynamic state based on something the
user has done. In the case of a static label, there is no *state*. The label
"Username" always is the label "Username" no matter what, so it's not
stateful.

That's my 2 cents atleast.

Re: Conditionally Render Different Fragments (via Radio Choice Selection)?

[Riyad Kalla]

JD,

If you flip the initial visible fragment to the 2nd one, does the inverse
condition apply? (frag2 is visible and frag1 isn't visible?)

If you check the source of the generated HTML, you are seeing the generated
placeholder tag for the 2nd fragment so it can be made visible right?

Re: Conditionally Render Different Fragments (via Radio Choice Selection)?

J.D.,

What did your HTML look like for each of these conditional "fragments" and
how were they represented in your code before you fixed it?

Curious what it looked like before/after for my own know-how.

Re: Debugging in Netbeans - Lists don't load

[Riyad Kalla]

Garrett,

I would start simple, remove Wicket as much as possible from this situation
first. In your DAO or whatever you are using to do the query and load the
results from the DB -- just System.out the contents of the list to the
console.

Until you get that working, don't bother thinking about Wicket and what is
going on there -- it will just muddy the water.

Check your console logs on startup, your persistence framework (Hibernate)
may be crapping out an error that is scrolling by really quick, like it
cannot find a driver or your credentials for the DB connection are wrong.

Also try and check the console when issuing your first query, look for the
same sort of data.

Troubleshoot that DB connection first and foremost. At that point, it's
either a Spring issue or something else, but make sure you get that data out
of the DB first before moving on.

Re: Print friendly panel

[Riyad Kalla]

This is what I've done in the past as well, allows your user to just "print"
the page they are staring at and have the browser do the right thing in
using an alternative style sheet for rendering the page -- this includes
using a lot of display:none to trim down the parts of the page that you
don't want printing. This way all you need on your page is a "Print" link
that invokes the Print dialog, no other popups ontop of popups.

Some info:

Re: Serialization and Form Models

[Riyad Kalla]

Matthew,

A quick absolute way to make sure those values are serialized is to use the
Java 'transient' keyword. But Wicket will be assuming that when a user hits
the Back button, that it can re-constitute the page from the serialized info
it has on disk, if it cannot, then yes you'll need a LoadableDetachable
model that can rebuild that expensive graph when demanded but you won't need
to persist it.

Re: Wicket-securty

[Riyad Kalla]

Josh,

I think if your security is just needing role/authentication enforcement
(e.g. "Ok Bob is an ADMIN, he can do all this stuff, but Jeff is a NORMAL
user, so he can only do this and Anon is ANONYMOUS so he can only view")
Wicket should have you covered. I'm not familiar with Shiro, so I don't know
what else it provides that you might need.

Re: Ajax refresh outer panel

[Riyad Kalla]

If there was a  container in your HTML that
contained your loggedIn or loggedOut panel, then I imagine in your page code
you would have a WebMarkupContainer that you did a removeAll() on then added
the appropriate panel to it when building the page.

I imagine your loggedOut panel has a Username/Password field and a "Login"
button on it, so that'll post to the server at which point you could do that
work?

Re: How can i know when a users redirects to other page

[Riyad Kalla]

Martin can you explain your use-case, namely what is the importance of
seeing which page a user is no-longer on?

Seems like a super-easy way to do this would be to extend a base-page that
updates a Session metadata element with the current page the user is on and
allow a listener to be notified when this changes?

But depending on who you want listening to this I suppose you could do away
with the whole listener/metadata thing and just have your basepage call some
trigger method onRender that would do some work?

Re: How can i know when a users redirects to other page

[Riyad Kalla]

1 other idea (among others that would probably work) is a custom
IRequestCycleProcessor impl that checks the returned IRequestTarget (
http://wicket.apache.org/docs/1.4/org/apache/wicket/IRequestTarget.html) to
see if it's sending back the PageRequestTarget (
http://wicket.apache.org/docs/1.4/org/apache/wicket/request/target/component/PageRequestTarget.html)
that belongs to the page that generates the temp file, and if it is,
generate the file, if it isn't, erase it.

I'll admit I've not done any of this, so I'd defer to someone smarter for
the "right" approach. These are just ideas.

Re: Cant Read Variable From PageParameters (Wicket 1.4.6)

[Riyad Kalla]

Can you paste the code for the page that isn't working? You have a
constructor for that page that takes a PageParameters arg that you named
'params' right?

Re: Making label visible using Ajax, does not update model

[Riyad Kalla]

Anna,
Try this:

==
f.add(new Label("label1", new PopertyModel(data, "label1")));
f.add(new Label("label2", new PopertyModel(data, "label2")));
==

That way when the model is queried for the value, the propertymodel
will dynamically query "data"'s appropriate property name (in this
case label1 and label2) for the values.

Re: image from outside web application directory

[Riyad Kalla]

Mike,

The solution is writing a wicket component that finds the image on-disk and
streams the bits back to the browser. Try these search results:
http://old.nabble.com/forum/Search.jtp?forum=13974&local=y&query=dynamic+image

and
these:
http://old.nabble.com/forum/Search.jtp?query=image+on+disk&local=y&forum=13974&daterange=0&startdate=&enddate=

Your
answer is in there somewhere. The thread recently (3 weeks ago?) about it
was pretty long and someone pasted a complete impl that they were using that
folks said worked great. I just don't recall the class name otherwise I'd
search for it :)

Re: Page Expired

[Riyad Kalla]

Alexander,

Maybe this has to do with the persistence store you are using to make Wicket
work on GAE not actually persisting your pages to a location that they can
be retrieved again? I know by default the DiskStore that Wicket uses won't
work on GAE, so I imagine you plugged something else in -- if you did and
it's just tossing out the previous versions of the pages, that would explain
what you are seeing "no version  of page" errors.

What store do you have configured?

Re: validate

If you have that string literally copy-pasted in some Java code somewhere,
you need to double escape the escape chars...

Re: [newbie] Wicket, Spring, Hibernate and transactions in views.

I'm not DB expert, but why are you using transactions for "read only"
(SELECTs) queries? I've only ever seen transactions used to wrap
INSERT/UPDATE/DELETE statements (writes)

Re: Wicket button label

[Riyad Kalla]

Natalie,

What have you tried thus far to change the label? Another approach
might be to set the visibility on the CancelButton to false and true
on another FinishButton and then refresh the whole button bar to paint
that state for the last panel?

Re: setResponsePage() in AjaxSubmitLink.onSubmit() redirects to relative URL

[Riyad Kalla]

Nikita,

The wicket team started the vote on if 1.4.7 was ready to go out a few
days ago, it should be either late this week or early next when the
release goes out if that helps at all (don't know how immediate your
need is).

[Riyad Kalla]

I take that back, the vote passed, looks like 24hrs per Igor's comment
on wicket-dev?

===
the vote has passed with

3 +1 binding votes and 5 +1 nonbinding votes

i will upload the artifacts to mirrors and write up an announcement
after the mirrors have synced (24 hours).

cheers

Re: how to use the google trends for searching wicket?

[Riyad Kalla]

You can use grouping and "AND" and "OR" operators to improve the
accuracy... but there is no great magic to Trends, it's hard to pull
awesome stats out of commonly named things from it.

Usually the news articles help you know if it's hitting the right
search items, but a lot of times they are missing. I just tried more
specific terms:

http://www.google.com/trends?q=(gwt)|(google+web+toolkit),+(apache+wicket)|(java+wicket)|(wicket+1.3)|(wicket+1.4)&ctab=0&geo=all&date=all&sort=0

and it comes up with garbage... using just 'wicket' isn't great
because if you Google for it, you'll notice maybe the 2nd/3rd/etc.
results are for basketing and what not.

Anyone else have suggestions?

Re: image from outside web application directory

GW,

Good pt... at the least it should probably be in the Wiki. I think it's just
an issue of one of the leads not having time to go through it's impl and
figure out if it should go in or not? I'm sure there are probably a few
different ways to write such a component.

Re: Planned 1.4.7 Release?

[Riyad Kalla]

The "hot item" in 1.4.7 I am aware of is the fix for redirected/relative
paths when using Ajax components that was broken in 1.4.6 -- and yesterday
Igor said he would begin promotion to the mirrors and writeup an
announcement, so I think the release is... "any minute now"?

Re: URL pattern /app/* does not work for Wicket 1.4.6 and WebSphere 6.1

[Riyad Kalla]

Steve,

So your context-root is /JobCenter and the URL mapping /app/* -- and after
submitting the form WebSphere(?) is redirecting to the server's root, not
even to /JobCenter?

I can't think of a case where WebSphere wouldn't honor the context root
atleast unless you are returning a redirect from the form in Wicket that is
incorrect? What does that onSubmit code look like?

Re: deployment problem

[Riyad Kalla]

bono,

Looks like some dependencies are missing from your WAR
===
***/server/DatabaseManager.java:[8,34] package
org.springframework.core.iodoes not exist

Can you grab the WAR, unzip it and check WEB-INF/lib and see if those libs
are in there? Might just be a packaging issue.

Re: Clear feedback panel

[Riyad Kalla]

I thought the feedback messages were stored in the request by default? At
least I remember a thread from a week and a half ago about a person doing a
redirect and loosing his messages so he had to manually switch to saving
them in the Session...

Re: Where to put an application's configuration parameters?

[Riyad Kalla]

David,

Given your requirements, I'd recomment putting them in a properties file
along side your custom WebApplication class for your particular application
and then inside of the WebApp's init method, reading in the properties file
and storing the information in the WebApplication.get/setMetaData methods to
store that free-formed information:
http://wicket.apache.org/docs/1.4/org/apache/wicket/Application.html#getMetaData(org.apache.wicket.MetaDataKey)

You
could be fancy and spin off a thread that checks every 10 mins for changes
to the files and re-sets the metadata info if you want to be able to change
that data while the app is running without a restart. Either way, it's just
a plain properties file.

Best,
Riyad

Best way to create a "Root Page" that every page in your app extends

[Riyad Kalla]

Hey guys, having a major brain-fart today... I swear I had this figured out
at one point.

I essentially want to create a RootPage (extends WebPage) that represents
the root of every page in my app. It has an associated RootPage.html file
with it that has all the DOCTYPE stuff in it, sets all the meta-tags at the
top and page title, and right inside the  tags, it has a:



The idea being that every page that extends RootPage, would provide the
actual body of the page.

I know I can do this with Panels, in that every single sub-page would
actually supply a Panel with the id "pageBody" to be added, but I was
curious what the "right" way to do this is.

Igor,
Thanks for the reply, found the page (ref:
http://cwiki.apache.org/WICKET/markup-inheritance.html), read it, felt
really stupid, and am now happily making pages :)

I think I just got a little bamboozed with all the seemingly different ways
to do this, but MI is exactly the type of solution I was looking for.

Best,
Riyad
