Re: Offline capable web application

[Igor Vaynberg]

i just dont see the point of wrapping a page made up of gwt components
in wicket wrappers. the *entire* front end has to live on the frontend
in order for the application to work offline...so whats the point?
anyways my two cents.

cheers,

Any components you write wouldn't use the typical client/ server
interaction that regular Wicket components do, but I don't see why you
wouldn't be able to write a wrapper around this functionality so that
at least you'd be able to use such functionality within a Wicket
application.

FWIW, I'm currently coding in GWT, something I really looked forward
to, because like most coders I like change, but man, I miss Wicket's
productivity. It's not a bad framework, but imho it's hard to beat
Wicket when it comes to churning out and integrating components.

having data only on the client will not help you unless you also have
behavior. these kinds of apps are really only feasible when you use a

It's three components, one parent (that holds the ultimate value) and
two children (that both hold values used to calculate the parent
value.

updates the parent (setConvertedInput) with one value that comes from
the minutes and seconds fields.

Isn't that all a matter of making clients smart? If you'd do it
without a web framework you'd use a local (client side) data store,
and have a mechanism to synchronize data later. Whatever you would
write can be wrapped as Wicket components. It might even be feasible -
though I'm not saying easy per se- to create generic components for
this, but I'm not that familiar with the new HTML (or now deprecated
Google Gear) functionality to say for sure. Just a hunch that a
capable coder should be able to do it :-)

Upload to Resource

[Karl M. Davis]

Howdy all, 

In the Wicket API, is there any way to have something other than a Form that 
can receive and process file uploads? Specifically: can a Resource accept form 
POSTs for file uploads? 

I ask because I'm trying to wrap the SWFUpload Shockwave applet in a Wicket 
component. Asking about it on the IRC channel, Igor mentioned I should "create 
a Resource that can receive the upload." I took a look through the code for 
Resource and its subclasses and I can't see any hooks in the API that would 
allow this. 

Am I missing something in the API? If not, I suppose I can poke around at the 
raw ServletRequest and try to extract the POST manually from there. Anyone know 
of any examples on how to go about that? 

Thanks very much, 
Karl

 Hi List,
 
 the following may looked flawed, so I'm happy to hear your suggestions: I 
 have a RegisterNewItem Form where a user can add new Items to a 
 shop/database. I have items of type CD (audiocd) with an attribute 
 PlayTime. I store this value as seconds and calculate the minutes to 
 display at runtime. For adding a new CD, I thought that it would be 
 inconvenient to have the user entering either seconds only, or how to 
 agree on a format like Min:Sec OR Min.Sec etc. My idea now is to provide 
 two textFields, one for the minutes and one for the additional seconds. 
 Now I have no idea how to properly use the model of the textfields and the 
 item-object, to calculate the seconds from both fields at submit time. Any 
 help appreciated.
 
 Please see the code from the Panel below (currently without a textfield 
 for the playtime).

Hello,

I'm not sure if the Palette is the best component to support what you 
are looking for.


Have you considered using a DropDownChoice (which makes finding the 
selected item trivial) and then using a DataTable to show the 
'selected' items?


Here is another approach with the Palette to add in an onclick event 
to each of the 's that render in the choices component:


1. Palette.newChoicesComponent() creates a Choices object.  
Choices inherits from AbstractChoice which has this method:

@SuppressWarnings("unchecked")
@Override
protected void onComponentTagBody(MarkupStream markupStream, 
ComponentTag openTag)


At the bottom of the method it does:

buffer.append("\nMap additionalAttributesMap = 
getAdditionalAttributes(choice);

if (additionalAttributesMap != null)
{
for (String s : additionalAttributesMap.keySet())
{
buffer.append(" " + s + "=\"" + 
additionalAttributesMap.get(s) + "\"");

}
}

buffer.append(">").append(value).append("");


I think this is the place to add in the "onclick" -> AJAX callback.

2. You can setup the Map for each choice by overriding the 
Palette.getAdditionalAttributesForChoices(T option) method.



I think something like:

new Palette("p", choices, renderer, 5, true) {

/* (non-Javadoc)
 * @see 
org.apache.wicket.extensions.markup.html.form.palette.Palette#getAdditionalAttributesForChoices(T) 


 */
@Override
protected Map 
getAdditionalAttributesForChoices(

T choice) {

Mapmap = new LinkedHashMapString>();


map.put("onclick", createAjaxCallback(choice));
return map;
}

So each option might have its own ajax behaviour or a common one with 
a URL parameter that represents the clicked option.


When the ajax behaviour is activated you can update your image 
accordingly.

Unfortunately your suggestion doesnt' work. That is because the 
"onchange" event only fires if i move an item from the left to the 
right box or vice versa. what i want is to get a notification when an 
item is clicked, not when it's moved. I managed to receive this 
notification by registering a onclick listener with the 
'choicesComponent' as shown in the code of my inital mail.
My problem is that i want to find out which precise item has been 
selected and use that information to get hold of the corresponding 
data object (in my case MediaItem) which contains a property 
'filename'. This property i want to feed into an Image component to 
have it display the corresponding image to the selected item in the 
Palette.

Re: Nested Forms

you cannot have an "isolated embedded form", as far as html is

IFormVisitorParticipant or by overriding form.process() on your main

Re: Offline capable web application

[Jeremy Thomerson]

What you describe here is different than what was implied by your first
comment.

What you now seem to be asking is this.  Please verify:

You have multiple install sites (satellite offices, etc), and each of them
has a server that runs the application on its own.  Users from that location
will connect to that server (i.e. users in the Dallas office connect to the
Dallas server, NYC users to the NYC server, etc).  You want Dallas to be
able to go "offline" - that is, disconnected from NYC, but you want the
Dallas users to still be able to use their application at their location
while the two offices are disconnected from each other.

If this is the case, then it's not a Wicket question - it's a database
question.  Basically you need a database that will handle multiple master
configuration where one master is still able to function without
connectivity to the second.  I haven't looked at this for quite some time,
but I'm sure you can find some resources out there describing it.  I know at
ApacheCon last year, the CouchDB guys were promoting the fact that you can
use CouchDB in such a situation.  However, I'll warn you that if you come
from a typical relational database background, CouchDB may not be your cup
of tea - and you'd probably have a hard time selling it within your
company.  You'll just need to find someway of doing multi-master replication
with a traditional DB server.

Re: Palette: access selected/clicked item

[minusquampefekt]

Unfortunately your suggestion doesnt' work. That is because the 
"onchange" event only fires if i move an item from the left to the right 
box or vice versa. what i want is to get a notification when an item is 
clicked, not when it's moved. I managed to receive this notification by 
registering a onclick listener with the 'choicesComponent' as shown in 
the code of my inital mail.
My problem is that i want to find out which precise item has been 
selected and use that information to get hold of the corresponding data 
object (in my case MediaItem) which contains a property 'filename'. This 
property i want to feed into an Image component to have it display the 
corresponding image to the selected item in the Palette.

That is a very strict definition that doesn't include hybrid
applications using Google Gears or a combination of HTML5 and
JavaScript.
I think the definition is too strict.

Building an application two times with different technology does not
feel like a very efficient way. But I would guess that Wicket's server
side state approach works contrary to the technologies used for
building offline web applications.

Re: Palette: access selected/clicked item

[Michael O'Cleirigh]

Hello,

Inside the Palette there is a Recorder which is basically a 
customized HiddenField that holds the id of each selected element.



/**
 * Returns recorder component. Recorder component is a form 
component used to track the
 * selection of the palette. It receives onchange 
javascript event whenever a

 * change in selection occurs.
 *
 * @return recorder component
 */
public final Recorder getRecorderComponent()
{
return recorderComponent;
}

So myPalette.getRecorderComponent().add(new 
FormComponentUpdatingBehavior("onchange"){


protected void onUpdate(AjaxRequestTarget 
target) {

/**
  I imagine something like this should do 
the trick, but i can't find anything like it:


  Media m = getSelectedItem();
  imgPanel.setFilname(m.getFileName());
*/

Iterator selectedChoices = 
myPalette.getSelectedChoices();


// let the image panel do something with 
the selected choices.

target.addComponent(imgPanel);

});

This should give you what you want.

Regards,

Mike
i have some trouble to access the currently selected item of a Palette 
component. By selected i mean the item which is highlighted if  a user 
clicks on any of the items within the palette. i need that access 
because i want to update an Image component which renders an image 
which reflects the selected item


here is the (simplified) piece of code i use to get notified if the 
palette is clicked:


final Palette palette = new Palette("palette", mediaModel, 
paletteModel , renderer, 10, true) {
private static final long serialVersionUID = 
-5683120408447757525L;


@Override
protected void onBeforeRender() {
super.onBeforeRender();

getChoicesComponent().add(new 
AjaxFormComponentUpdatingBehavior("onclick") {
private static final long serialVersionUID = 
-6216894553871444828L;


@Override
protected void onUpdate(AjaxRequestTarget 
target) {

/**
  I imagine something like this should do 
the trick, but i can't find anything like it:


  Media m = getSelectedItem();
  imgPanel.setFilname(m.getFileName());
*/
target.addComponent(imgPanel);
}
});
}
};

Re: Offline capable web application

[James Carman]

Since Wicket stores state on the server side in the session (and page
store), I'd say you're going to have a rough time with this one.  This
has been discussed before:

RE: Offline capable web application

[Frank Silbermann]

Any application that executes _offline_ is not a _web_ application --
unless the system consists of a stand-alone application containing a web
server that runs on the client (e.g. via jetty) so that both client and
server are running on the same box.

Theoretically, a Wicket application that runs on a jetty server on the
client could synchronize itself, when possible, via non-Wicket web
services that run on the server.

But why go that route?  I'd build just an ordinary stand-alone client
application, e.g. using Java WebStart and Swing, that could optionally
connect to the server.  There's no need for Wicket on the server, since
the client would provide the user interface.  (The client would have to
do that, if it were to be able to run stand-alone.)

Re: Ajax and OpenSessionInViewFilter problems

I had/have this problem too. Right now i use serializable hibernate objects
together with an IModel implementation that does not detach the object.

Object are serialized into the session and when the user presses the save
button the objects are reattached  to the current hibernate session
and committed.

Re: [OT] Wicket changed my life !

[Leon Nieuwoudt]

We just did an initial presentation to a high profile client for our first
Wicket-based app (previously we used PHP extensively), and it went well.

The entire process from getting a prototype up, doing database stuff (mostly
thanks to Hibernate), custom components, etc. went rather smoothly.

The learning curve was slightly steep once we started doing interesting UI
interactions (and also that really annoying LazyLoad exception during tests
that I still can't figure out), but it's worth the effort.

I love spaghetti, but not in my code.

Thanks guys :)

Re: Ajax and OpenSessionInViewFilter problems

[Martin Sachs]

Hi ,

if you use LDM for a form Model.getObject will load the Objects from DB
in each request. This is not a Problem, if all data are in the Form
allready.

Ajax-submit sends the Form incl. all field as parameters, if valid set
it to this object and then you have to Store it in this request.  If you
want to collect datas in a transient (not persistent) way you could use
the Session, or Serializable objects.  The state of data is always in
the form or component.

I use Hibernate with serializable objects AND Lazy-loading. This is not
always a nice solution. To work with this Objects, i reattach the
hibernatesession on each method call via AspectJ. This allows to use
DB-Mapped serialized POJOs with Lazy loading in e.g. PropertyModels.

I would not recommend to use DTOs, but in some cases this is a cheap
solution.

regards
Martin

PageExpiredException on ajax calls if apps pages are opened in different tabs

[sachin kumar anumula]

Hi,

   1. Firstly, I did take a look at all posts regarding this exception
   available on PEE like
hereand
   
here
   2. Secondly, Its not a Serialization issue as most conclude and that the
   exception occurs every time there is an ajax call happens with pages from
   apps are opened in 2 tabs
   3. I do not implement any other algorithms and use the packaged
   SessionStore
   4. Session is not invalidated and PageMaps are not quenched and the
   default PageMap = null is in place and pages are serialized and deserialized
   to diskstore
   5. The URL looks like this at exception occurence
   http://localhost:8080/myApp/secure/jas/tom/?wicket:interface=:3
   6. Exception trace is as such
   org.apache.wicket.protocol.http.PageExpiredException: Cannot find the

Re: Large number components and redering time

[Juha Palomäki]

If you want to avoid mixing HTML and Java, you could write your
component with using a templating engine, such as Velocity or
Freemarker.

I believe there is wicket-velocity project somewhere that provides for
example Panels that can render Velocity templates files.

Security report suggests to use Apache Wicket

[Martijn Dashorst]

"Cross-site scripting is the practice of embedding malicious script
into a Web page that can execute when users visit the page. To ward
off such attacks, the report recommends using frameworks and libraries
to control output, including "Microsoft's Anti-XSS library, the OWASP
ESAPI Encoding module, and Apache Wicket." Programmers should use
strong character encoding and set the browser cookie session to
HttpOnly."

Mention of Wicket in the original report (http://cwe.mitre.org/top25/):

Prevention and Mitigations

Architecture and Design

Use languages, libraries, or frameworks that make it easier to
generate properly encoded output.
Examples include Microsoft's Anti-XSS library, the OWASP ESAPI
Encoding module, and Apache Wicket.
