Re: How to execute Wicket project in Eclipse
I just created a Main application using Jetty and run it through that... my
main server is jboss/tomcat but for development Jetty works real fine and is
very easy to set up.
Something like:
public static void main( String[] args ) throws Exception
{
logger.debug( "Starting web server..." );
// create an instance of the web server
Server server = new Server();
// Create a connector channel to allow communication with our local
web server
Connector connector = new SelectChannelConnector();
connector.setPort( 8080 );
connector.setHost( "127.0.0.1" );
// add the connector to the server
server.addConnector( connector );
// create a web application context
WebAppContext applicationContext = new WebAppContext();
// set the context path of the application
applicationContext.setContextPath( "/" );
// path to the exploded application. Will automatically locate
web.xml
applicationContext.setWar( APPLICATION_BASE_DIRECTORY );
// set the application context onto the server
server.setHandler( applicationContext );
// kill server on shutdown
server.setStopAtShutdown( true );
// start the web server
server.start();
server.join();
}

IE7 + Vista + SP1 + AjaxFallbackLink.
Hi. My friend has a default installation of the above. I notice that onClick(null) is being called in AjaxFallbackLink therefore making the target null. He tells me that XMLHttp is enabled and the browser appears to work fine with other AJAX enabled sites. Any thoughts as to why this may be? Anyone encountered this? It doesn't happen with other Vista +IE7 computers... (unfortunately I run Linux/Mac so can't test). A search on the forum showed nothing significant.

Feedback panel filtering...
Hi. I couldn't find the answer on the forum, but I'm sure its been done before: I have a page with a feedback panel at the top for 'serious' errors. The page contains a form. The form has input components (for example text required field). When the user hits submit I want the form component feedback panels to show the form component related errors. Only on a major issue (for example after submit we try to connect to a server - if the server cannot be connected to then there is a major issue) I want to appear in the page feedback panel. For the life of me I cannot figure out how to get this filtering working. Any advice welcome.

Re: Autocomplete text concatenation
One idea I had was to do something like the following code:
This class would be added to the AutocompleteTextField (as below).
inputSoFar would be the input to the getChoices() method minus the string we
are looking for, so for example:
fred,jim,b
inputSoFar would be 'fred,jim'. input (to getChoices( String input )) would
be 'b' after chopping off "fred,jim," - once the user selects 'bob' from the
autocompleter, then input would be 'bob' also.
So finally in the ChangeBehavor class, inputSoFar + input would resolve to
"fred,jim,bob" and be populated in the text field.
Two problems with this:
a) It seems a bit hokey.
b) I have to store inputSoFar as a private member variable in the
AutocompleteTextField, which seems like an overhead to me.
Anyone got any thoughts?
Many thanks, Graeme.

Hi there! Something like that - but I was hoping it might be easy to somehow do this with autocompletetextfield from wicket extensions - I guess there may be a little trickery to manipulating the unsubmitted text in the textfield itself (although this comes in as the input for getChoice so I was wondering if it were somehow useable from that). francisco treacy-2 wrote: > > if i understand correctly you need a "multi" autocompleter. > > do you mean something like this? > http://digitarald.de/project/autocompleter/1-1/showcase/delicious-tags/ > (i have integrated it with wicket, it's indeed used when you edit > topics of a module in wickethub). > > francisco > > > On Mon, Dec 15, 2008 at 8:36 PM, Graeme Knight > wrote: >> >> Hi. >> >> Couldn't find an answer but perhaps this is a common thing to want to do: >> >> Using an AutoCompleteTextField I want to allow the user to select choices >> as >> he types, then update the text area by appending the selected choice. >> Similar to the way a web mail application would allow a user to type >> email >> address after email address and see them appended to the text field. >> >> Is there an easy way to achieve this? >> >> Many thanks, Graeme. >> -- >> View this message in context: >> http://www.nabble.com/Autocomplete-text-concatenation-tp21020322p21020322.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 >> >> > > - > To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org > For additional commands, e-mail: users-h...@wicket.apache.org > > > -- View this message in context: http://www.nabble.com/Autocomplete-text-concatenation-tp21020322p21020726.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
Autocomplete text concatenation
Hi. Couldn't find an answer but perhaps this is a common thing to want to do: Using an AutoCompleteTextField I want to allow the user to select choices as he types, then update the text area by appending the selected choice.

Re: IMG SRC URL in iframe - part 2.
Hi Ernesto,
Certainly the way you suggested makes a lot of sense to me. It is a nice
resource that can just receive the requests and process based resolution of
the SRC attribute - given that the content if the iframe is populated after
the body has been rendered and really Wicket is not doing any processing
from a component point of view.
Thanks again, Graeme.

IMG SRC URL in iframe - part 2.
Hi.
I recently had a question which I put to the forum here:
http://www.nabble.com/IMG-SRC-URL-in-iframe.-td20805408.html Generating IMG
SRC to replace CIDs.
I believe I have found the answer (thanks to Ernesto's help) which I would
like some verification of if possible (not sure if it needs a wiki page):
Here's the solution:
1) In my application I create a new shared resource:
@Override
protected void init()
{
getSharedResources().add( "cidImageResource", new CIDImageResource()
);
mountSharedResource( "/imageStuff", "cidImageResource" );
}
2) My CIDImageResource class is a subclass of DynamicImageResource.
It has a single important implementation of a method in it: byte[]
getImageData().
This method will be passed a filename as a parameter. This filename is
the image file we wish to render and is known by its attachment on
url-to-cid-image-resource?filename=image.png . Note that 'image.png' is the
name of a file that has previously been serialized onto the file system and
replaces the CID in the HTML email that we are rendering.
3) There is a magic class that I have that loads the HTML email data from
the filesystem and parses out the CIDs, replacing the
SRC="CID:sdkfhsakhfskdfh13213123" with the correct URL to the correct file.
This URL is gotten in the following way:
First we get the following:
ResourceReference ref = new ResourceReference(
"cidImageResource" );
RequestCycle requestCycle = getRequestCycle();
We then loop around all our known CID references in the HTML email and call
the following:
String contentFileName = UserDefaults.resolveUserHomePath(
userName ) + uploadData.getUploadFileName();
ValueMap parameters = new ValueMap();
parameters.put( "filename", contentFileName );
String link = requestCycle.urlFor( resourceReference, parameters
).toString();
Once we have the link to the file, we replace the correct "CID:". We do this
numerous times for the entire HTML email.
4) The HTML email is rendered in an iframe.
See my previous post, which I got working, and sets the innerHTML on the
iframe:
http://www.nabble.com/Populate-IFRAME-innerHTML-on-AJAX-load-of-panel.-td20887803.html
iframe innerHTML post.
The shared resource (cidImageResource) that I created in the application is
then called repeatedly during rendering of the iframe, and the image byte
data is returned to the browser and rendered correctly in place of the CIDs.
Does this sound about right? I hope this may be useful to someone else if it
is!
All the best, Graeme.

Hi Bruno.
I WILL create a Wiki page soon. How do I do this - is there a process?

RE: Populate IFRAME innerHTML on AJAX load of panel.
Yahhhyahhh!
The answer appears to be a HeaderContributor with a call to
renderOnLoadJavascript.
Bruno - you're a star!
I will respond with a more sensible sentence than above as soon as I have
proven it (so far it works).
Rgds, Graeme.

Re: Populate IFRAME innerHTML on AJAX load of panel.
Hi guys, I'm making some progress. wicketGlobalPostCallHandler doesn't seem to be working for me, but I can do something like this after the iframe: StringBuilder buffer = new StringBuilder( "" ); buffer.append( "IFrameArea.populateContent( false, true, 'hello world' );" ); buffer.append( "" ); Label scriptLabel = new Label( "scriptLabel", buffer.toString() ); scriptLabel.setRenderBodyOnly( true ); scriptLabel.setEscapeModelStrings( false ); add( scriptLabel ); This will add a nice bit of Javascript into the whole lot that will call the populateContent function (hurray). Now the thing is, the text (hello world) flashes on the screen - then disappears. If I hit the 'refresh' button on the browser then the innerHTML 'hello world' sticks. If I can solve this tricky problem then I think I'm good to go. Is it REALLY this simple? Why does Wicket have to be so cool? Cheers, Graeme.

Re: Populate IFRAME innerHTML on AJAX load of panel.
Hi Ernesto,
No - I didn't solve this problem as yet. However, this is part of the
process of parsing the HTML prior to insertion on the innerHTML. If I can
get that bit working I'm going to get back to our thread on the CIDs very
soon!
Cheers, Graeme.

Hi Bruno,
No I didn't try this the Label idea... I'll give it a go!
Thanks for the link I'll let you know how it works out ... watch this space!

Re: Populate IFRAME innerHTML on AJAX load of panel.
Hi Bruno,
Right, that far I DID get. I have a Javascript file that contains the
required Javascript for my editor.
(Sorry, I don't have the code now):
When the user hits the tab and the panel goes into another context I create
the panel, add a HeaderContributor that adds the Javascript file.
This panel is not created via a page refresh - it is replaced as per the
code above (i.e. currentPanel = new ). Will the HeaderContributor
actually be utilized at this point or is a full page refresh required?
My BIG problem (this is the crux) is HOW to call that Javascript function -
the call to 'popupateContent' effectively has to be AFTER the iframe is
initialized (so an innerHTML exists). This can't be part of a
HeaderContributor - it has to be further down the chain of execution. My
confusion is how to make this happen.
Almost there! What are the guidelines for the Wiki when I get this working?
Perhaps I can submit to the Wicket people for verification?
REALLY appreciate your discussion on this.
Cheers, Graeme.

Re: Populate IFRAME innerHTML on AJAX load of panel.
Hey Bruno,
Perhaps my ramblings with myself didn't make myself clear.
I am simply wanting to populate the innerHTML with content. I have it
working wonderfully with Tapestry but not with Wicket as I'm not sure of the
correct way of doing it.
Essentially my component will be a wysiwyg editor. I don't want to use
standard ones because I have written my own AND I will be doing some fancy
stuff with the content at a later date.
So perhaps here's the correct question:
What's the best way to set innerHTML on an iframe?
I have a javascript function that I would like to call, which is something
like the following:
IFrameArea.populateContent = function( isEditable, allowDocumentTags,
content )
{
var iFrame = document.getElementById( IFrameArea.FRAME_NAME );
if( iFrame.contentWindow != null )
{
if( iFrame.contentWindow.document != null )
{
var iFrameDocument =
iFrame.contentWindow.document;
iFrameDocument.open();
if( allowDocumentTags == true )
{
iFrameDocument.write('');
iFrameDocument.write( '' );
iFrameDocument.write('');
}
iFrameDocument.write( content );
if( allowDocumentTags == true )
{
iFrameDocument.write('');
}
iFrameDocument.close();
if( isEditable == true )
{
IFrameArea.designModeOn();
}
}
}
};
isEditable indicates whether the iframe is editable or not,
allowDocumentTags indicates whether the iframe should contain basic html
tags and CSS, and the content is ... the content (created by the server) -
this is my Tapestry-esq implementation, so of course it is open to change.
The magic question: How do I get this in the HTML for the 'context' panel?

Bruno!
I absolutely would love to write a wiki page on this if I can make it work -
and you are right - conversation with myself *might* help others who perhaps
have a similar problem.
I'm not quite there yet :-( - perhaps tomorrow!

Hi.
Perhaps AbstractAjaxBehavior may help - I will have a look. Anyone with any
experience with this please let me know. It would be appreciated!

Populate IFRAME innerHTML on AJAX load of panel.
Hi.
I have an application with links that switch panels using AJAX:
:
private Panel currentPanel;
:
ContactsListPanel manageContactsPanel = new ContactsListPanel();
currentPanel.replaceWith( manageContactsPanel );
currentPanel = manageContactsPanel;
:
One of my panels has an IFRAME on it which I wish to populate with content
on rendering. I would like to set the innerHTML through Javascript, rather
than set the source (the innerHTML will be injected with content that is
modified on the server and not a static source page).
I have a Javascript function that can be called once the IFRAME has
(effectively) been rendered:
function initializeIFrameArea()
{
IFrameArea.populateContent( "${originalContent}" );
}
The populateContent function simply sets the innerHTML on the IFRAME. The
'originalContent' is my modified content to be injected into the innerHTML.
My question is this:
1) On entering the panel, I was wondering if it is possible to use a
HeaderContributor (i.e. this is NOT a full page rerender) to add the script
containing the IFrameArea Javascript on which the populateContent is called.
I can't have the initializeIFrameArea function on the page from the start
because I am using a Variables Model to change the value of originalContent
on the fly (i.e. when the user enters this panel the content could be one of
many possibilities).
2) On rendering I want to be able to call initializeIFrameArea, but I do not
understand how I can get this into the HTML of the panel so that it calls
the function after the IFRAME is effectively rendered and innerHTML exists.
Perhaps there is a better approach - as this seems complicated (I had to do
this with Tapestry, so I'm not sure if Wicket has a more elegant approach).
Any thoughts most welcome.
Thanks, Graeme.

Calling Javascript on AJAX load of panel.
Hi.
I have a panel that loads different content depending on a context (i.e.
clicking on a tab moves it to another view, etc).
One of the views is an iframe which will have content populated by
Javascript.
I have something like this as a header contributor, which populates 'hello
world' into the iframe:
IModel variablesModel = new AbstractReadOnlyModel()
{
private static final long serialVersionUID =
-4744542904096678956L;
public Map getObject()
{
Map< String, CharSequence > variables = new HashMap< String,
CharSequence >();
variables.put( "originalContent", "Hello world" );
return variables;
}
};
add( TextTemplateHeaderContributor.forJavaScript(
TextReadPanel.class, "IFrameLoader.js", variablesModel ) );
Two questions:
1) Is the header contributor added to the html (this is ajax so there is no
page refresh).
2) How to call the function in IFrameLoader.js (initializeIFrame()) AFTER
the iframe has rendered?
Perhaps the above is the wrong way to do the following:
1) User clicks on tab.
2) Panel is switched into text reading 'context'.
3) IFrame is rendered, innerHTML of iframe is populated through the
initializeIFrame() Javascript function (rendering originalContent).
Does this sound plausible in Wicket?
Many thanks, Graeme.

Re: IMG SRC URL in iframe.
Hi, thank you - this is invaluable information.
So basically what you are suggesting is something like:
1) Read the HTML content (this will be set on the innerHTML of the iframe).
2) Parse the content to find the each IMG SRC CID - replace this CID with a
URL to /images/xxx.
3) Set the HTML into the iframe.
4) On rendering the iframe IMG SRC will point back at the server that will
serve up the image, essentially.
Appreciate your help!
Graeme.

Re: IMG SRC URL in iframe.
Hi Ernesto, I think that is exactly what I am after - just not certain how this implementation works in Wicket. It was real easy with Tapestry as all I did was get hold of the URL, append a path to the image, and replace the CID in the HTML with the image URL. Are there any examples of this sort of functionality?

Re: IMG SRC URL in iframe.
Oh, My use case is this: 1) Load up HTML email content. This content has CIDs which need to be resolved to URLs. 2) I will put the HTML content into the iframe using some Javascript to manipulate the innerHTML. 3) Before I do step 2 I need to convert the CID to a URL that points to an image file on the server. Its this URL construction that concerns me. Many thanks for any suggestions, Graeme. Graeme Knight wrote: > > Hi, > > I would like to use an iframe on my page that contains IMG tags.

IMG SRC URL in iframe.
Hi, I would like to use an iframe on my page that contains IMG tags. I would like the IMG tag SRC to point back to the server to load up the image. What would be the best way to construct the URLs in Wicket?

Re: Page Map File Sizes.
I guess I can answer my own question: So let's say our page is 50k. We have 1000 users on a server. With each user having 100 click throughs before cleanup. So I figure roughly (51200x100) * 1000 = 5,120,000,000 So 1000 users clicking 100 times each on a 50k page will take up 5 GB of space. The above scenario is pretty far fetched! Does anyone know how page cleanup occurs? Thanks, Graeme. Graeme Knight wrote: > > Hi.

Page Map File Sizes.
Hi. I hope this appropriate for this forum. I am writing a fairly heavy AJAX rich application with two pages - A login page and a work page. I was interested in progress so far regarding serialized page state, so I tracked the size of my page map file as I clicked around the application. Below is the size change in the file for my single user. I would like to know if this is as expected as I have no metrics from any other place - perhaps you have experience. Each value is the size of the page file in kilobytes after each click of a link: 5.9 25.5 49.3 71.9 95.7 116.4 140.2 < so I see my page map file is growing as I assumed it would. My file therefore changed by the following amount each click, indicating that my page is around the 22 kilobyte mark: 19.6 23.8 22.6 23.8 20.7 23.8 Does this sound about right? Is there something wrong with the growth of the file? Is it excessive? When does the file cleanup?

Re: Adding/Removing a AjaxSelfUpdatingTimerBehavior...
Hi.
Thanks for that. I was worried about removing behaviors - but thanks for the
information.
I'm going to look at how easy it is to change time on an
AjaxSelfUpdatingTimerBehavior?
I need a poll anyway so I am thinking of polling once every five minutes and
then when the refresh is occurring I can poll evey 5 seconds, then when
finished - back to five minutes...
Cheers, Graeme.

isEnabled on AjaxSelfUpdatingTimerBehavior.
Hi.
I have looked at removing the timer from a component when a condition is not
true, but according to the forums this is not possible.
Recommended is the use of isEnabled. I have the following code, but
isEnabled doesn't appear to be working.
I'm after a way of allowing a user to start a process by pressing a link,
then as the process continues over several minutes the WebMarkupContainer is
updated (every 5 seconds using an AjaxSelfUpdatingTimerBehavior) and when
the process finishes, stopping the timerbahavior until the link is next
pressed. I think this must be a common thing to do so any information would
be most welcome.
My refresh link that the user presses to render an indicator and a
percentage based on the fact a refresh is occuring:
public final class RefreshLink extends AbstractAjaxFallbackButtonLink
{
private static final long serialVersionUID = 1825145981122180572L;
@Override
public void onClick( AjaxRequestTarget target )
{
// create the refresh process worker
RefreshWorker refreshWorker = new RefreshWorker();
// execute the refresh thread
refreshWorker.refresh( Visit.get() );
// get the page
AccountViewPage page = AccountViewPage.class.cast( getPage() );
// get a reference to the markup container component containing a
refresh indicator and percentage complete
Component container = page.get( RefreshPanel.CONTAINER_ID_PATH );
target.addComponent( container );
}
}
In the panel containing the indicator (shown as the process continues along
with a percentage complete):
:
WebMarkupContainer container = new WebMarkupContainer( CONTAINER );
Image refreshIndicator = new Image( REFRESH_INDICATOR,
IconFactory.getSmallGIF( REFRESH_INDICATOR ) );
AttributeModifier attributeModifier = new
RefreshImageAttributeModifier();
Label percentageCompleteLabel = new Label(
PERCENTAGE_COMPLETE_LABEL, new RefreshLabelReadOnlyModel() );
container.add( percentageLabel );
container.add( refreshIndicator );
container.add( attributeModifier );
container.setOutputMarkupId( true );
container.add( new RefreshTimerBehavior() );
add( refreshButton );
add( container );
:
And the refresh timer:
public final class RefreshTimerBehavior extends
AjaxSelfUpdatingTimerBehavior
{
private static final long serialVersionUID = -6061033495202259806L;
private static final int FIVE_SECONDS = 5;
/**
* @param updateInterval
*/
public RefreshTimerBehavior()
{
super( Duration.seconds( FIVE_SECONDS ) );
}
/*
* (non-Javadoc)
*
* @see
org.apache.wicket.behavior.AbstractBehavior#isEnabled(org.apache.wicket.Component)
*/
@Override
public boolean isEnabled( Component component )
{
boolean isEnabled = false;
if( Visit.get().isRefreshing() )
{
isEnabled = true;
}
return isEnabled;
}
}
Now, isEnabled is getting called, but the base class method onTimer is also
getting called - indicating to me that the value of isEnabled is being
ignored - I was hoping that a return value of false would tell the timer to
stop, but it keeps ticking away every five seconds. I obviously can't remove
the timer behavior but I would like to disable and enable it in the
following conditions:
1) Enable: The timer gets enabled (i.e. isEnabled is true?) on
Visit.get().isRefreshing() equal to 'true'.
2) Disable: The timer gets disabled (i.e. isEnabled is false?) on
Visit.get().isRefreshing() equal to 'false'.
I simply only want the timer to tick when the refreshing process via the
worker is occuring and not otherwise.
I hope this is clear... Any thoughts? This is with 1.3.5 Wicket.
Many thanks for your time, Graeme.

Adding/Removing a AjaxSelfUpdatingTimerBehavior...
Hi. What's the best way of achieving this effect: 1) Button is pressed to start a process. 2) Updating of various panels contained within a WebMarkupContainer occurs on a 5 second period. 3) Process stops and updating of WebMarkupContainer also stops. I understand the use of AjaxSelfUpdatingTimerBehavior - this really is a question of the best way to add/remove from the WebMarkupContainer on demand, or enable/disable on demand. Any thoughts most welcome.

Re: IDataProvider Implementation.
Hi guys,
I am using hibernate and it is caching (which is great) so that overhead is
not a problem -
after some reflection I think it appears to me that because you get rid of
the loadabledetachablemodel to 'save database hits' (which if cached,
doesn't really) then the affect is more serialized data. Bad.
Got it.
Thanks, Graeme.

IDataProvider Implementation.
Hi. >From the examples I've seen the IDataProvider implementation of the iterator method brings back (for example) a list of keys from the database. The model method uses something like a LoadableDetachableModel to populate a model for use by the consumer using the list of keys previously retrieved. This seems like a lot of database hits to me. Is this simply because of the serialization/model mechanism? It seems to me that the iterator could/should bring back the data in one hit and then after use be detached. Is this common?

IDataProvider and Session related data.
Hi. Just learning about IDataProvider and DataViews. I've scoped out the repeaters examples but this may be a little different... If I have a userId (for example stored in the Session) of the user as he is logged in and I wish to use that userId as a criteria for getting hold of the correct data using a IDataProvider (for a DataView list), then should I pass in the userID to the IDataProvider implementation and just store as a private variable? Is there a better way of getting hold of (or passing this) information into the IDataProvider implementation to limit storage/serialization?

Re: LoadableDetachableModels with replicated data fed in through constructors.
Thanks Jeremy.
I have those conversations often - especially over silly things.
I need to go back and look at the ins and outs of serialization. I guess if
I have several private references to the same object in multiple
LoadableDetachableModels I guess the actual object itself only gets
serialized once (i.e. there are never multiple copies of it being stored
over time on disk)... Not to concerned. Just a mad moment :-) One of many
:-) More to come :-)
Cheers, Graeme.

Re: LoadableDetachableModels with replicated data fed in through constructors.
Oh - tired! Long hard days working with spaghetti in my day job and lasagna
in my night time...
I realized this may be a dumb question. Doesn't an object only get
serialized once no matter how many references would be made to it in a
LoadableDetatchableModel? I.e. you wouldn't get 10 userIds serialized, just
1...
Thanks, Graeme. :-)

LoadableDetachableModels with replicated data fed in through constructors.
Hi.
I have a number of LoadableDetachableModels that are each designed to
perform a task of getting data from a database. Each model is dependent on a
couple of pieces of information (1) an identifier about the current user (2)
a primary key of a parent data object. I'm trying to work out the mechanics
and life cycle of the model object...
So, my class might look like:
public class GetAccountsModel extends LoadableDetachableModel
{
private Long userId;
private Long parentPrimaryKey;
public GetAccountsModel( Long userId, Long parentPrimaryKey )
{
this.userId = userId;
this.parentPrimaryKey = parentPrimaryKey;
}
.. override load here .
}
Let's say I have ten similar LoadableDetachableModels all of which take the
same parameters in the constructor, but all of which return different data
from the database.
When I create a LoadableDetachableModel as above and call the super
constructor of (for example) a ListView, the model is fed into the ListView
and load is called (with the transient object being detached).
The userId and primaryKey get serialized. So if I have ten similar models
which get different data, I am serializing the same (or very similar) data
10 times, specifically the userid.
If figured I could probably make the userID and primaryKey transient then
they would not serialize. I'm not sure if this would have a negative affect
if I go to another page (i.e. current page is out of memory) and come back -
what happens?
Now my example above is not too bad resource wize - you may only be talking
about a couple of Longs being serialized ten times (not a massive hit), but
what about if the objects in my LoadableDetachableModel are fairly big?
Is there a way of destructing and reconstructing the model automatically so
I don't need to worry about this serialization of the model private data?
Or... am I panicking about nothing? I may be completely misunderstanding the
whole concept here.
Any explanation welcome.
Regards, Graeme.

Re: Moving from Tapestry to Wicket?
Hey Eelco! Awesome! Thanks for your answers - they really helped. I appreciate the time. BTW, Wicket in Action is a really well written book compared to others in the genre. Thanks to you and Martijn for the hard work! It came at the right time for me and we have decided to make the move from Tapestry. Let you know how it goes, and I'll be on the forums plenty I am sure!

Re: Feedback/Error message.
Hey! Cool - add a feedback panel then set error - I like that! I didn't get to that part in the Wicket in Action as yet but I see how it works! Actually - my authentication method is very similar to the one on the book (again not got to that part yet), so I'm pretty psyched I'm heading in the right direction! I'm assuming if I wanted a panel with an icon and an error message I just create a component with a feedback panel and an image and populate accordingly?

Feedback/Error message.
Hi. Loving Wicket so far! I had a search and had trouble finding the answer to this one, if anyone can help: 1) I have a simple form with username/password and a submit button. 2) User enters username/password and hits submit. 3) onSubmit authenticates against the database through a load on a LoadableDetachableModel, and returns the result as the model's object. Let's say there is an error on authenticating against the database - what is the easiest way of giving the user feedback that his username/password was wrong? I naively thought I might be able to do some sort of conditional insert of a component into the page or form (similar to Tapestry). My solution was then to add a panel (regular not feedback) to the page which consists of an error icon and a custom message. I would like to update this component on the re-render so it doesn't display if there isn't a problem, but it does if there is a problem (couldn't get isVisible working this way). What's the Wicket way?

Re: How does serialization work?

Re: How does serialization work?
Hi. I wondered another thing - how and when are the serialized objects cleaned up? Is there a mechanism for making sure large amounts of memory or disk are not soaked up by long running sessions and lots of user interactions? Thanks again, Graeme.
