Re: how to reuse a label in the same page?

2008-12-12 Thread Martijn Dashorst

The fact that you want to bind a component in two places and complain
that you can't, is a code smell: you should extract that component to
a panel or fragment and reuse the panel (/fragment).

 Nope, wicket:id is a 1-1 mapping at the same dom tree level. You can
 reuse id's at different levels or in different branches of the dom

Yeah, Jquery started something which I tested a couple of months ago with no
luck.

Writing/Finding a leaner comet client is in the TODO right now...

The idea Jesse McConnel has is of making it simpler to marshall data to-from
clients.
To make it, an actual bus for communication.

We haven't had much time to discuss all this though.

Hi, a new version of wicketstuff-push was moved to the

group of projects, as push-parent (as was specified in the wiki)

A couple of new things were done:

It is no longer compatible with java 1.4, is built for wicket 1.4
and
requires jetty 6.1.14.
The dependencies on dojo have been reduced even further, so this
package
is
basically just a cometd client/server project for wicket.
The RemoveListener is now working and is extended with a new type
of
WicketRemoveListener that allows access to the Wicket Application
Singleton
and the session that registered the singleton (i thought of a
couple of
ways
to register them, and decided to choose the one present in the
code for
it)

Please let me know of any suggestions, ideas for the proj.

Alright, I agree with you, but think about. There are some cases where creating 
a fragment or a panel to reuse, wouldn't address the main advantage. We could 
save a *lot* of memory usage this way, and I think it would be a cool feature.

RE: how to reuse a label in the same page?

2008-12-12 Thread Pointbreak

- No you will not save a lot of memory. Wicket components are fairly
small. Memory usage will/should mostly be in the application models, and
they are easy to share between components.
- It will introduce a complexity nightmare with no real benefits (imho)
in the framework though.

  Nope, wicket:id is a 1-1 mapping at the same dom tree level. You can
  reuse id's at different levels or in different branches of the dom
  tree, but not as siblings.
 
  a href=# wicket:id=foospan wicket:id=foo/span/a works
  but another
  a href=# wicket:id=foo/a will fail (and rightfully so)

   What are you trying to achieve?
  
   Here are some ideas that may give the desired effect, depending on what
   that is ...
  
   1 - Make a model for your data and give that to all the Label instances
  as
   required, (but each with their unique id and separate markup).
   2 - Use a repeater (like a ListView) to render several labels (no
   repetition of Java code or markup).
   3 - Write a method that takes a model (or just a String) and an id, 
   that
   returns an appropriately configured Label instance  (saves on repeating
   Java code - still need markup per component and your own unique ids).

Re: What is your experience on the time of development ?

2008-12-12 Thread Antoine Angenieux



Martin Sachs wrote:

Your right !

Already I have developed three Wicket apps (12 month of work for a man), I
know how fast i can do thinks with wicket, but i need knowledge of e.g. JSF
to say wicket is THE FRAMEWORK for the next big site. Maybe with JSF all
things will be developed a lot faster, maybe not. Is other technologies also
Maintainable very well, in comparison to wicket ? That questions cant be
answered with looking at a HelloWorld application.


Right. Always choose the right tool for the job ;) in my case, a small 
dev team (1 ~ 3 devs), many variants of the same kind of middle-sized 
webapps, and exactly the kind of apps that belong to wicket's comfort zone.




Every application has its own unique requirements on style, architecture, so
we cant reuse only very abstract components. That works fine with wicket. So
if we have a new project we develop the basics components for this project
(very fast).
Agreed. However, I found that when dealing with web applications rather 
than web site, where a simple and effective HTML / CSS / Ajax based UI 
is enough, I could reuse many stuff from previous projects.


Naturally, what I reuse most often as is are the custom components 
(read wicket components) we have already built. The only project 
specific implementation required for those are usualy the IModel implems 
to use, and sometimes a few CSS / HTML tweaks.


As we use Wicket only for the UI layer (classical Spring / Wicket 
stack), I find that most often, when desiging the requirements for the 
UI, I find existing designs and working implementations either in our 
previous projects, in wicket user list or by googling... Thankfully, 
there are still times where I have to come up with some fresh design.




Maybe you can estimate a factor of time (for development or maintaining) in
comparison with JSP, JSF, ... or whatever you know else


As meaningfull as it can be, three years ago we rewrote our base 
applications that were based on a Struts 1.x / JSP / Spring / JDBC stack.


The app was a small / middle sized app at the time (~ 30 struts actions, 
~ 100 jsps) representing a ~5 months of workman. It tooks us 2 months of 
workman to rewrite from scratch with Wicket. Maintenance time on live 
applications has been cut down by a factor 2 on average.


New project developpement time has been cutoff by a factor 3 on average.

Off course, this is not only due to switching to Wicket (event though it 
is the major factor), but also to using other techs. where usefull like 
Hibernate  co, and rewriting from scratch an application with more than 
3 years of feedback on the previous version ;)


I won't talk about JSF as after my first evaluations of the tech. in our 
company context, and continuously ranting inside my head for the 3 days 
investigating it, I decided that the only way I would use JSF was to 
torture me to death :D


Cheers,

Antoine.

Martin

I think the development with Wicket is two times faster than Struts. But
what are your experiences on JSF, Rails/Grails, SpringMVC/SpringWebFlow.

Anyone you know the development-time from experience ?


(P.S.: The applications must use AJAX and many custom components or tags
in
JSP, not just a hello world sample)

Using ajax for generating a pdf

2008-12-12 Thread Emanuele Gesuato


Hi there,

Reading previous posts i have discovered the existence of the yui 
context menu in wicket stuff that now i'm using in a project.


More specifically, i'm using wicket 1.3.4 with wicket-yui-core 1.3.0 
from the wicket 1.3.0 branch of wicketstuff.


I would like to do a non-ajax click in my context menu because i need to 
generate a pdf report and propose to the user the classic download 
window of the browser. Using ajax, the pdf is generated but the ajax 
response is empty and the user doesn't see anything.

This is my actual code in the MenuItem.onClick(AjaxRequestTarget, targetId):


IResourceStream stream = new ByteArrayResource(application/pdf, 
s.toByteArray()).getResourceStream();
		RequestCycle.get().setRequestTarget(new 
ResourceStreamRequestTarget(stream));		



With these lines if i do a normal submit the user could see the 
download window with the pdf generated. Using an ajax-click it doesn't work.


The YuiContextMenuBehaviour in the respond method calls the 
YuiContextMenu.onClick(AjaxRequestTarget, targetId). But in the 
YuiContextMenu there is a method onClick() which seems not called by 
anyone.


For me, it seems that the onClick() could resolve my issue (it doesn't 
use ajax) but i don't know why it is not called by anyone. Is it 
deprecated ?



Thanks,
Emanuele

Is wicket:extend strictly required if including entire html child?

2008-12-12 Thread Antony Stubbs


Is it possible to use markup inheritance without having to use
wicket:extend in the children? I'd like to be able to use MI without the
children html knowing. Just extending the super component should be enough
in a lot of situations. Particularly when extending panels which are naughty
and don't have htmlbody tags, and dont have any html which shouldn't be
in the result. 

I.e. can we have wicket default to simply effectively wrapping the entire
html contents in wicket:extend if there is no extend tag?

Re: Hot deployment / code swapping

2008-12-12 Thread samk

See Thread at: http://www.techienuggets.com/Detail?tx=51475 Posted on behalf of 
a User

I also have the same problem. Even I added 

getResourceSettings().setResourcePollFrequency(Duration.ONE_SECOND); 

to WebApplication class.

I am using wicket 1.3.4.

Before Wicket come to Apache I never have this problem before.



In Response To: 


Hi everybody,

I have read in some older messages of this list that wicket by default takes
care of re-deploying changed classes and HTML files, does that still apply?

It does not work for me, not even with a fresh quickstart project. Neither
HTML files nor Java classes are reloaded when they are changed.

Are there any issues with this under certain circumstances (e.g. having
vista ;-)?

What I just did is this:



mvn archetype:create -DarchetypeGroupId=org.apache.wicket
-DarchetypeArtifactId=wicket-archetype-quickstart -DarchetypeVersion=1.3.4
-DgroupId=com.mycompany -DartifactId=myproject

cd myproject

mvn package

mvn jetty:run

[changed HomePage.class and HomePage.html]



The changes do not have any effect until I restart jetty.

Any hints on this issue are highly appreciated, thanks a lot in advance!

Very nice indeed. Based on your example I build my own:

public class ConventionalComponentResolver implements IComponentResolver {

public boolean resolve(MarkupContainer markupContainer, MarkupStream
markupStream, ComponentTag componentTag) {  
CharSequence wicketId = componentTag.getString(wicket:id);
if ( submitLink.equals(wicketId) ) {
markupContainer.autoAdd(new SubmitLink( submitLink ),
markupStream);
return true;
}

Setting a relevant value for radio buttons without using RadioChoice

2008-12-12 Thread ArchieC


Hi All

Im fairly new to wicket and Im going insane with an issue Im having. Ive
been doing a trawl of many forums, Wicket in action, Pro wicket, nabble,
asking questions of friendly people and trying every option I can think of
to work this out for myself using RadioChoice, RadioGroup and odd
combinations of both.

I promise Ive been trying to avoid asking this question on the forum cause
Im expecting someone to call me an idiot. So here is my question.

RadioChoice has the ability to set a value thats not the standard radio7
type value. As far as we (myself and the java developer I am working with)
can see, we cannot seem to do the same for a Radio component in a
RadioGroup. Are we barking up the wrong tree completely or is there a way to
set a value to an ID from our database (for example).

EG.
Instead of input type=radio name=group value=radio7 /

I get input type=radio name=group value=353 /  (353 being the
user_id of one of the accounts, set in option.getValue() - please see code
snippet below). 


Here is the reason we cant just use a RadioChoice. The list we are making
contains about 1000 User account names, each with a user level denoted by an
icon next to each name and radio button. RadioChoice doesnt give the option
of doing different icons (Label with IMG html in it for Icons) for each name
as setPrefix just sets one for the whole list. The list is basically acting
like a drop down box so that I can select one of the accounts for editing on
the next page.

Im really stumped by this as I cant seem to find any reference to setting
this value on a Radio component and I cant believe the creators of Wicket
would make a pointless component.

Here is my code if that helps

RadioGroup group=new RadioGroup(group, new Model(id));
final ArrayList SelectOptionLevel selectOptionLevel =
getDdcChoices();
ListView persons=new ListView(persons, selectOptionLevel) {
/**
 * 
 */
 private static final long serialVersionUID = 1L;
  

protected void populateItem(ListItem item) {
SelectOptionLevel option = (SelectOptionLevel)
item.getModelObject();

//Exampe of Icon  setting
item.add(new Label(levelImage,  img
src='images/icons/icon1.gif'/).setEscapeModelStrings(false));
 
Radio radio = new Radio(
radio, 
new PropertyModel(modelObject, user)  

~~ Need to set the value of the radio to


my option.getValue() value.
);
item.add(radio);
item.add(new Label(name, option.getLabel()));
}
};
group.add(persons);
add(group);

Apart from not getting a value it all looks great just as I want.

Erm from looking at the docs, Both Radio and RadioGroup only have an Id and
an IModel in their constructor unlike RadioChoice which has a choice

Hmm it does'nt.. And you cant even overrride getValue() on radio since 
it's final... :( Come it, I posted something about the fact that radio 
uses autoIndex once regarding jmeter..


But you can override onComponentTag, I guess I'd probably roll my own 
and rip most from Radio, but let it take the optional choicerenderer..

Re: Setting a relevant value for radio buttons without using RadioChoice

2008-12-12 Thread Michael O'Cleirigh


Hi ArchieC,

The way RadioGroup works is that it renders to a hidden field and stores 
the selected value of the selected Radio.


i.e. the rendered markup is not that relevant and the model object for 
the selected radio will be placed into the model for the RadioGroup when 
the form submits.


This is how I've used it:

RadioGroup group = new RadioGroup (group, new Model());


Radio apple = new Radio (apple, new Model (Fruit.APPLE));

Radio orange = new Radio (orange, new Model (Fruit.ORANGE));


group.setModelObject (Fruit.APPLE);

Here by default the first radio is selected.

When the form submits group.getModelObject() will return either 
Fruit.APPLE or Fruit.ORANGE depending on the selected radio button


In your case the RadioGroup will have as its model Object the value of 
the selected radio.getModelObject() so whatever the value of user is 
coming from the PropertyModel() for the selected option.


Regards,

Mike

Re: SpringBeanLocator and @SpringBean performance issue

as far as i can see the problem is on the other side of the fence.
applicationcontext has much better metadata about its beans then we do
so it should be cached there as it can be done so properly.

if this is urgent we can build a temporary cache into
springbeanlocator, but its not the proper thing to do imho. if we
follow this logic then we can actually start caching bean references
as well and essentially build our own applicationcontext

 [...snip...]

 I found that if we specified a name in @SpringBean (e.g. @SpringBean(name =
 foo)), then we would avoid this bottlenecking and our requests per second
 improved 50-75%. It appears that the SpringBeanLocator.isSingletonBean()
 call will do an expensive lookup of the bean name against
 BeanFactoryUtils.beanNamesForTypeIncludingAncestors() if the name isn't
 specified, even if the bean is already cached. By specifying the @SpringBean
 name parameter, you avoid the lookup.

 This feels like a bug, though I don't know who to should address it, Wicket
 or Spring. Specifying a name in @SpringBean is optional, and the performance
 gain of a cache lookup of already-injected beans is consequently defeated by
 the isSingletonBean() call, which is called every single time a SpringBean
 is injected. This implies Wicket should be addressing it. OTOH, Spring
 BeanFactoryUtils.beanNamesForTypeIncludingAncestors() is clearly a
 bottleneck if called too frequently, though when I've found performance
 issues in Spring code (e.g. http://jira.springframework.org/browse/SPR-4505)
 they've implied that Wicket should have better bean caching (though they've
 fixed them anyway).

 So.. how would one go about addressing this problem? It's a big performance
 issue for those deploying a Wicket app using @SpringBean on multi-core
 systems. I'm able to hack around it in our app, but not knowing much about
 how Spring and Wicket should be interacting I'm not sure I can give an
 educated guess.

 Thanks,

 Before Wicket come to Apache I never have this problem before.



 In Response To:


 Hi everybody,

 I have read in some older messages of this list that wicket by default takes
 care of re-deploying changed classes and HTML files, does that still apply?

 It does not work for me, not even with a fresh quickstart project. Neither
 HTML files nor Java classes are reloaded when they are changed.

 Are there any issues with this under certain circumstances (e.g. having
 vista ;-)?

 What I just did is this:



 mvn archetype:create -DarchetypeGroupId=org.apache.wicket
 -DarchetypeArtifactId=wicket-archetype-quickstart -DarchetypeVersion=1.3.4
 -DgroupId=com.mycompany -DartifactId=myproject

 cd myproject

 mvn package

 mvn jetty:run

 [changed HomePage.class and HomePage.html]



 The changes do not have any effect until I restart jetty.

 Any hints on this issue are highly appreciated, thanks a lot in advance!

Re: how to reuse a label in the same page?

Martijn,
Actually, what I described does work - try this on any page:

JAVA (added only once - since you couldn't add two with the same ID anyway):
add(new Label(test, this is a test));

HTML:
span wicket:id=test[]/spanbr /
span wicket:id=test[]/spanbr /

OUTPUT:
span wicket:id=testthis is a test/spanbr /
span wicket:id=testthis is a test/spanbr /
Right or wrong, it currently works that way.  (1.4-SNAPSHOT - and I know
I've used it in past versions as well)

   Jason,
  
   What are you trying to achieve?
  
   Here are some ideas that may give the desired effect, depending on
 what
   that is ...
  
   1 - Make a model for your data and give that to all the Label
 instances
  as
   required, (but each with their unique id and separate markup).
   2 - Use a repeater (like a ListView) to render several labels (no
   repetition of Java code or markup).
   3 - Write a method that takes a model (or just a String) and an id,
 that
   returns an appropriately configured Label instance  (saves on
 repeating
   Java code - still need markup per component and your own unique ids).

Re: Is wicket:extend strictly required if including entire html child?

no it is not. not including wicket:extend means the child wants to
completely override the markup of the parent.

 Is it possible to use markup inheritance without having to use
 wicket:extend in the children? I'd like to be able to use MI without the
 children html knowing. Just extending the super component should be enough
 in a lot of situations. Particularly when extending panels which are naughty
 and don't have htmlbody tags, and dont have any html which shouldn't be
 in the result.

 I.e. can we have wicket default to simply effectively wrapping the entire
 html contents in wicket:extend if there is no extend tag?

Re: Case sensitivity and PackageRequestTargetUrlCodingStrategy

One other thing - I think that the contract of IClassResolver would mean
that rather than returning null, you throw a ClassNotFoundException.

 Sounds like an interesting idea.  Here are a few thoughts I had after
 seeing it.  Hopefully these are helpful.

 1 - Say you had a page CustomerAdminLoginPage - this yields 4,194,304 
 combinations!
 Cache the result - either the class you found or the fact that you could not
 find a class.  (you will have 2 to the nth power, where n equals the length
 of the simple name)
 2 - DON'T use StringBuilder just to split it later - that's not what it's
 for!  It's very slow and is constantly resizing it's internal array.  You
 could use something like the code I pasted below to use a single array,
 initialized ahead of time to the proper size.

 3 - I would suggest not even holding an array of possible combos - longer
 class names take a ton of memory because of all the millions of strings
 created.  If you must go through all combos to try to find a match, just
 look for the match in your loop rather than looping to create an array of
 combos and then re-looping to try to find a match.

 4 - Now - I would suggest seeing if you can avoid looping through all
 possible combos altogether.  Look at how Wicket Annotations (in Wicket
 Stuff) does classpath scanning...  I would think that this would be much
 more efficient - scan the package ahead of time and find all classes in the
 package and cache their names.  Then just do a case-insensitive look into
 your cache - this saves you all the memory and processing trouble of ever
 computing all the combos and trying to load potentially millions of
 non-existent classes.

 5 - If you get this to work and work well, add it to wicketstuff-minis or
 a similar project where others can easily use it - let me know if you need
 help accomplishing that.


 Here's an example of an improved method of finding the combos - probably
 could still be improved considerably, but this is a significant improvement
 over your first rough draft.  (Although see point 4 - I recommend not even
 using this method at all)

 private static int capsCombinations(String[] combos, String word, int
 startIndex, int arrayIndex) {
 if (arrayIndex == 0) {
 word = word.toLowerCase();
 combos[arrayIndex++] = word;
 }
 if (arrayIndex == combos.length) {
 return arrayIndex;
 } else {
 while (startIndex  word.length()) {
 char[] chars = word.toCharArray();
 chars[startIndex] =
 Character.toUpperCase(chars[startIndex]);
 String string = String.valueOf(chars);
 combos[arrayIndex++] = string;
 arrayIndex = capsCombinations(combos, string,
 ++startIndex, arrayIndex);
 }
 return arrayIndex;
 }
 }

 public static void main(String[] args) throws Exception {
 long start = System.currentTimeMillis();
 String name = CustomerAdminLoginPage;
 String[] combos = new String[(int) Math.pow(2, name.length())];
 capsCombinations(combos, name, 0, 0);
 System.out.print(combos.length +  combos - took );
 System.out.print((System.currentTimeMillis() - start) +  millis -
 used );
 Runtime rt = Runtime.getRuntime();
 System.out.println((rt.totalMemory() / 1048576) + MB of memory);
 }

 I am looking for some feedback any may have on this:
 Let's say I've mounted a package com.company.package using
 PackageRequestTargetUrlCodingStrategy

 my
 page mounts to be case-insensitive in the case that a user has caps lock

 PackageRequestTargetUrlCodingStrategy this works for the /foo part, but
 not the classname part, obviously.

 So I implemented a CaseInsensitiveClassResolver that delegates to a
 DefaultClassResolver. In the case that the DefaultClassResolver cannot
 find
 the class, the CaseInsensitiveClassResolver tries to load the class by
 trying different combinations of upper/lower case in the classname. So,
 for
 bar it would try to resolve com.company.package.Bar, 
 com.company.package.bAr, com.company.package.baR, etc, obviously
 finding
 com.company.package.Bar and returning that class.

 This works pretty well. Now, obviously it's not the most efficient thing,

That's right - but if the devs regard this as abuse, there's no guarantee
that this still works in the next version. That's why I wondered what is the

 specified, even if the bean is already cached. By specifying the
 @SpringBean
 name parameter, you avoid the lookup.

 This feels like a bug, though I don't know who to should address it,
 Wicket
 or Spring. Specifying a name in @SpringBean is optional, and the
 performance
 gain of a cache lookup of already-injected beans is consequently defeated
 by
 the isSingletonBean() call, which is called every single time a
 SpringBean
 is injected. This implies Wicket should be addressing it. OTOH, Spring
 BeanFactoryUtils.beanNamesForTypeIncludingAncestors() is clearly a
 bottleneck if called too frequently, though when I've found performance
 issues in Spring code (e.g.
 http://jira.springframework.org/browse/SPR-4505)
 they've implied that Wicket should have better bean caching (though
 they've
 fixed them anyway).

 So.. how would one go about addressing this problem? It's a big
 performance
 issue for those deploying a Wicket app using @SpringBean on multi-core
 systems. I'm able to hack around it in our app, but not knowing much
 about
 how Spring

Ajax response not completed

2008-12-12 Thread Emanuele Gesuato


Hi there,

I'm sorry for sending two email the same day, but i've got a problem 
that is very strange for me. I'm using wicket 1.3.4 with the patch 
WICKET-1838 provided by Matej Knopp and i'm testing the page on firefox 
3.0.4.


When i click on an ajax link that generates a pdf, the file correctly 
shows to the user but the mouse is in waiting state and in the ajax 
debug window i've got ajax blocked in invoking pre-call handler.

Here the log:

INFO: Using XMLHttpRequest transport
INFO:
INFO: Initiating Ajax GET request on 
?wicket:interface=:3:table::IActivePageBehaviorListener:3:amp;wicket:ignoreIfNotActive=trueaction=StampatargetId=tablecontextMenuId=menurandom=0.7506497972643358

INFO: Invoking pre-call handler(s)...


When i click on the ajax link the following code is executed:
...

PageParameters params = new PageParameters();
params.add(file, /home/eg/test.pdf);
setResponsePage(FakePageForAjaxPrint.class, params);
...


The FakePageForAjaxPrint is an empty page mounted on a specific 
QueryStringUrlCodingStrategy that in the decode method does the following:



public IRequestTarget decode(RequestParameters requestParameters) {
	String filename = ((String[]) 
requestParameters.getParameters().get(file))[0];


final File file = new File(filename);
IResourceStream resourceStream = new FileResourceStream(file);

	ResourceStreamRequestTarget rsrt = new 
ResourceStreamRequestTarget(resourceStream) {

@Override
public String getFileName() {
return file.getName();
}
};
try {
resourceStream.close();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return rsrt;
}


So, when the link is clicked the pdf is showed in the download window of 
the browser, but the ajax is blocked in Invoking pre-call 
handler(s)... and the mouse pointer is in loading state.
I can click as many times i want in the ajax link and the pdf is always 
showed to the user.


How can i complete the ajax response ?


Sorry for the long email,
Thanks,
Emanuele

RE: how to reuse a label in the same page?

Really, if we think about the DOM tree and XMLs, we'll see that it is possible 
to put some information in different places, but that information is declared 
only once.

Wicket works with XHTML (XML over HTML). So why not support this? If one 
decides to refer to a component declared in another piece of the html, and 
duplicate that (html) code, it is possible to do it anyway, with Javascript.

DropDownChoice with Model for data and HashMap of key/values



Hi all,

I've been over all the DDC examples but am still stumped by this one.  
I have a model (pojo) which holds user preferences, the preference for  
each item being an Integer.

ie

public class UserPreferences {

int preferenceOne;
int preferenceTwo

constructor

getters and setters for the ints above

}

I now want to render a form that has a DDC for each of the preferences  
in my model. The list of choices that needs to go into the DDC should  
come from a HashMap or similar (in reality it will come from a  
database) because I want to store the number attached to the item  
selected, not the display string.


ie
LinkedHashMap choices = new LinkedHashMap()
choices.put(43, Something);
choices.put(64, Something else);
choices.put(87, blah);

which should render the select list as:

select name=preferenceOne
option value=43Choice Something/option
option value=64Choice Something else/option
option value=87blah/option
select

When clicking submit, the value (ie 43) should be attached to the  
relevant item in the Model (ie preferenceOne would be 43), then I can  
save it to the database.


Everything I've tried with ChoiceRenderer etc seems to get mixed up  
with the different data models etc.


Can someone please present a snippet of code on how to do this, I'm at  
my wits end. I cannot for the life of me find any explicit info  
separating the models/data as above.




thanks,
Steve

Re: Setting a relevant value for radio buttons without using RadioChoice

2008-12-12 Thread Nino Saturnino Martinez Vazquez Wael


Hi Michael

I believe that this is not what Archie asked about, he wanted to place 
database id's in the value of the radios.. Dont know why he wanted to 
though... I might have gotten it wrongly though..


regards Nino

Michael O'Cleirigh wrote:

Hi ArchieC,

The way RadioGroup works is that it renders to a hidden field and 
stores the selected value of the selected Radio.


i.e. the rendered markup is not that relevant and the model object for 
the selected radio will be placed into the model for the RadioGroup 
when the form submits.


This is how I've used it:

RadioGroup group = new RadioGroup (group, new Model());


Radio apple = new Radio (apple, new Model (Fruit.APPLE));

Radio orange = new Radio (orange, new Model (Fruit.ORANGE));


group.setModelObject (Fruit.APPLE);

Here by default the first radio is selected.

When the form submits group.getModelObject() will return either 
Fruit.APPLE or Fruit.ORANGE depending on the selected radio button


In your case the RadioGroup will have as its model Object the value of 
the selected radio.getModelObject() so whatever the value of user is 
coming from the PropertyModel() for the selected option.


Regards,

Mike




RadioGroup group=new RadioGroup(group, new Model(id));
final ArrayList SelectOptionLevel selectOptionLevel =
getDdcChoices();
ListView persons=new ListView(persons, 
selectOptionLevel) {

/**
 *  */
 private static final long serialVersionUID = 1L;
 
protected void populateItem(ListItem item) {

SelectOptionLevel option = (SelectOptionLevel)
item.getModelObject();
//Exampe of Icon  setting
item.add(new Label(levelImage,  img
src='images/icons/icon1.gif'/).setEscapeModelStrings(false));
 Radio radio = new Radio(
radio, new 
PropertyModel(modelObject, user)  ~~ Need 
to set the value of the radio to

my option.getValue() value.

);
item.add(radio);
item.add(new Label(name, option.getLabel()));
}
};
group.add(persons);
add(group);

Apart from not getting a value it all looks great just as I want.

extra 'onclick' is generated for an image wrapped by a link

I have the following plain HTML where I want an image to be a link to
another Wicket-managed page:

wicket:linka href=ProductPage.htmlimg
src=../images/products_welcome.jpg border=0/a/wicket:link


The link for that page is generated fine, but then Wicket adds an 'onclick'
event to the 'img' tag that takes the user directly to the image:

wicket:linka
href=?wicket:bookmarkablePage=:com.max.web.page.ProductPageimg
src=../images/products_welcome.jpg border=0
onclick=window.location.href='../images/products_welcome.jpg';return
false;/a/wicket:link

This seems absolutely wrong.  The result is that a click on the image will
take users to directly to that image; sometimes it will then continue on to
the right (ProductPage) page, so users see the image by itself before going
to the right page, but often it just stops at the image.

There is no Java code associated with this.  I get it in 1.4-rc1 (as well as
1.4-m3).

What is happening, and how can I stop it from generating the 'onclick'
javascript?  Thanks!

Here are some ideas that may give the desired effect, depending on
  what
that is ...

1 - Make a model for your data and give that to all the Label
  instances
   as
required, (but each with their unique id and separate markup).
2 - Use a repeater (like a ListView) to render several labels (no
repetition of Java code or markup).
3 - Write a method that takes a model (or just a String) and an id,
  that
returns an appropriately configured Label instance  (saves on
  repeating
Java code - still need markup per component and your own unique

RE: how to reuse a label in the same page?

One more thing: the Server-side will not know about foo1 (references to 
'foo'). Instead, this would be controled from the javascript, client-side.

 Hi all,

 I've been over all the DDC examples but am still stumped by this one. I have

 a model (pojo) which holds user preferences, the preference for each item

 being an Integer.

 ie

 public class UserPreferences {

 int preferenceOne;

 int preferenceTwo

 constructor

 getters and setters for the ints above

 }

 I now want to render a form that has a DDC for each of the preferences in my

 model. The list of choices that needs to go into the DDC should come from a

 HashMap or similar (in reality it will come from a database) because I want

 to store the number attached to the item selected, not the display string.

 ie

 LinkedHashMap choices = new LinkedHashMap()

 choices.put(43, Something);

 choices.put(64, Something else);

 choices.put(87, blah);

 which should render the select list as:

 select name=preferenceOne

 option value=43Choice Something/option

 option value=64Choice Something else/option

 option value=87blah/option

 select

 When clicking submit, the value (ie 43) should be attached to the relevant

 item in the Model (ie preferenceOne would be 43), then I can save it to the

 database.

 Everything I've tried with ChoiceRenderer etc seems to get mixed up with the

 different data models etc.

 Can someone please present a snippet of code on how to do this, I'm at my

 wits end. I cannot for the life of me find any explicit info separating the

 models/data as above.



 thanks,

 Steve

Re: What is your experience on the time of development ?

2008-12-12 Thread Marcelo Morales

Hello

I worked on a JSF project last year. This year I worked on a wicket
project. Both were approximately the same size and complexity.

Granted. You learn from experience. The second time around you do
something (or something quite similar), you do it much, much better.
AND I had previous experience with JSF (Nearly two years worth) and
not with Wicket.
AND I had good expertise on HTML/JavaScript, which I could leverage on
Wicket, but not on JSF.

It took half the time.

I truly believe that JSF was meant to sell tools to developers,
whereas wicket seems more from programmer to programmer you
know... pragmatic. I am yet to see how the new application performs on
production. But, as far as I see, I am about to become a Wicket
advocate.

I think I am seeing the light.

Anyone you know the development-time from experience ?

Re: Setting a relevant value for radio buttons without using RadioChoice

2008-12-12 Thread Michael O'Cleirigh


Hi Nino,



I believe that this is not what Archie asked about, he wanted to place 
database id's in the value of the radios.. Dont know why he wanted to 
though... I might have gotten it wrongly though..


You're right that he wanted to use the database id but from his example 
there didn't seem to be any client side use of this information.   My 
thinking is that he renders a list of users denoted by radio buttons and 
he want to encode the user id (for a LDM?) as the value for use on the 
form submission processing (i.e. which user to work with in the next stage).


Because there is no requirement for the user id on the client side there 
is no reason to care about the value used by the Radio as it is just 
used internally by RadioGroup to know which model object to use when the 
form is submitted.


There is no need for an IChoiceRenderer in this case because the Model 
object of each Radio is never rendered.


He should just encode what he needs in the Model of each Radio and 
expect to find it in the model of the RadioGroup when the form submits.


In his example:

RadioGroup group=new RadioGroup(group, new Model(id));
   final ArrayList SelectOptionLevel selectOptionLevel =
getDdcChoices();
   ListView persons=new ListView(persons, selectOptionLevel) {
   /**
*  */
private static final long serialVersionUID = 1L;
protected void populateItem(ListItem item) {
   SelectOptionLevel option = (SelectOptionLevel)
item.getModelObject();
   //Exampe of Icon  setting
   item.add(new Label(levelImage,  img
src='images/icons/icon1.gif'/).setEscapeModelStrings(false));
Radio radio = new Radio(
   radio, new 
Model(option.getValue())  // -- this is how to wire the Radio Model

   item.add(radio);
   item.add(new Label(name, option.getLabel()));
   }
   };
   group.add(persons);
   add(group);


This will make group.getModelObject() return the option.getValue() (i.e 
the user id) for the selected view item and allow him to proceed to the 
next step.


Regards,

Mike

 uses to output that markupid for the javascript that needs to
 manipulate the dom nodes.

 outputs:

 div id=foo1Foo/div

 Then it would be possible to do, for instance, an Ajax update over all 
 nodes.

 what happens once you add a behavior that uses markup id? or even call
 setoutputmarkupid(true) on that component?

 While I don't typically use this, or have this use case, I'm not clear on
 what is fundamentally wrong with this - you have a component you want two

Re: wicket pages as spring beans to utilize spring aop

2008-12-12 Thread miro


Yes its   the same problem I resolved it with the suggestion you pointed
aspectJ.I am using aspectJ compiler to   introduce some meta information to
my pages, the only reason I donot want to have super class   is the ability
to swap a class use it or not with least changes and in my case just an
annotation.
By the way If I set some an object in threadlocal in onClick method and call
setResponsePage() and setRediret(true)  will I  have this object in thread
in the new page ?

 Miro,
 
 Is this related to the CGLIB problem you were having? Did the Spring guys
 find an answer on their forum? If you did solve it, what did your fix
 entail? 
 
 In terms of introducing stuff to your pages, given that the framework
 will never be aware and able to utilise any such introduction there seems
 to be little benefit in making introductions directly to the page; why not
 make a base class for the pages you have in mind that can hold a reference
 to an object which is the target of the introduction (it can be an inner
 class if you need to access your page instance's state)? Is that not a
 simpler design (ie you don't have to design your own custom page
 resolution for Wicket).
 
 If you really want to add a new way for Wicket to locate pages (ie as
 Spring managed beans as you say), I'd start by looking at how the
 IRequestTarget,  RequestCycle and general mount strategy implementations
 interact but I'm sure one of the core developers will be able to give you
 a good steer - it's an interesting question (albeit, possibly academic).
 
 By the way, I guess you know that you can use AspectJ type configuration
 for Spring AOP, so you could write your aspects in a way applicable to
 both, but include an aop.xml in your MATA-INF and add the AspectJ agent to
 your command line to enable introduction to unmanaged beans whilst
 avoiding the self problem.

Re: What is your experience on the time of development ?

2008-12-12 Thread Jason Lea

Our company started with Tapestry 5 last year.  Early this year we had 
the chance for the team to try Wicket after getting frustrated with 
Tapestry.
I wrote a small comment here about it:  
http://www.theserverside.com/news/thread.tss?thread_id=50634#268364


Tapestry 5 seemed to be fast due to the live class reloading.  So you 
would code a bit, check the page in your browser, and then code a bit 
more.  But as soon as you hit a problem it seemed to take hours to get 
around it.  We had to write lots of custom ajax and javascript for all 
sorts of simple cases.  This left us with pages that generally worked 
but without any tests to confirm behaviour.  It think the java classes 
looked ugly too, with various public getters for anything that should 
appear on the page.  It made it hard to estimate how long a page would 
take because we would hit tricky problems quite often.


When we changed to Wicket, the speed tended to be the same at first 
which was surprising.  We decided to do Test Driven Development because 
we could use the WicketTester to help in development of our 
pages/components.  We finished the 2 month project in the same time as 
we estimated for doing it in Tapestry 5, but were were also writing unit 
tests and 3/4 of the team were learning Wicket.  Also our estimates for 
doing the project in Tapestry involved sharing components from our 
existing application.


We are much faster now, our estimates are very accurate now, we have 
lots of tests so we are happy to refactor/maintain code.  The style of 
coding is quite different now.  We set up the basic html + wicket class, 
write a test to make sure the page renders, then start adding more tests 
and components.  After an hour of writing tests/code we might check it 
once in the browser.  It gives you a great feeling to spend that much 
time in the IDE, getting lots of green bars as the tests pass then 
launch it in the browser and it just works.


We are now rewriting  the existing application in Wicket, page by page, 
moving components+tests we wrote into a shared module so we can use them 
in both projects.  Re-use yay!


So I guess we could say our development time might be 1.5 - 2 times 
faster.  Our maintenance is faster again,  maybe 4-6 times, because we 
can just write a new test to show the behaviour we want, fix the code 
and we can be confident we haven't broken anything else.  With our old 
application we would have to test the page/ajax/javascript by hand.


Martin Sachs wrote:

I'm looking for a little comparison of the development-time for Applications

I think the development with Wicket is two times faster than Struts. But
what are your experiences on JSF, Rails/Grails, SpringMVC/SpringWebFlow.

Anyone you know the development-time from experience ?


(P.S.: The applications must use AJAX and many custom components or tags in
JSP, not just a hello world sample)

What are your suggestions to ease separation of UI and dev teams?

Please help (documentation references, etc) with good ways to work with
Wicket where we have separate UI and dev teams. I'm looking for any
practices people have found helpful because of the UI surprises we keep
hitting.

For example, our UI group has been inserting graphics and regular links
between parts of our site. We're able to work through things fairly well,
but there's a case where Wicket adds behavior and/or styling in unexpected
ways:

http://www.nabble.com/extra-%27onclick%27-is-generated-for-an-image-wrapped-by-a-link-td20980894.html

This is something where I would like the UI people to be able to create
graphics and internal links at will without creating Java components or
involving developers. (We'll try avoiding wicket:link.) Another example of
surprise is when UI team creates links and Wicket changes the styling (eg.
disabling self-referential link and adding the em tag). Thankfully we
figured how to turn that off, but it took effort; I'd love to be able to
turn off all special rules like that, or somehow tell Wicket minimize
intervention!

I'm trying to maximize our UI team's ability to work independently on
look-and-feel and only involve developers when the functionality is
obviously dynamic. Maybe it'll take a few more months of trial and error,
but we appreciate any suggestions to ease this process. Thanks!

Trent

My first cut at such a list:

- Emphasize and re-emphasize to UI people NOT to play with wicket:id
values. Ever. :-)
- Avoid wicket:link. Try full url ?wicket:bookmarkablePage=:Page
instead. (Other options?)
-

http://www.nabble.com/extra-%27onclick%27-is-generated-for-an-image-wrapped-by-a-link-td20980894.html

 I found that if we specified a name in @SpringBean (e.g. @SpringBean(name
 =
 foo)), then we would avoid this bottlenecking and our requests per
 second
 improved 50-75%. It appears that the SpringBeanLocator.isSingletonBean()
 call will do an expensive lookup of the bean name against
 BeanFactoryUtils.beanNamesForTypeIncludingAncestors() if the name isn't
 specified, even if the bean is already cached. By specifying the
 @SpringBean
 name parameter, you avoid the lookup.

 This feels like a bug, though I don't know who to should address it,
 Wicket
 or Spring. Specifying a name in @SpringBean is optional, and the
 performance
 gain of a cache lookup of already-injected beans is consequently defeated
 by
 the isSingletonBean() call, which is called every single time a
 SpringBean
 is injected. This implies Wicket should be addressing it. OTOH, Spring
 BeanFactoryUtils.beanNamesForTypeIncludingAncestors() is clearly a
 bottleneck if called too frequently, though when I've found performance
 issues in Spring code (e.g.
 http://jira.springframework.org/browse/SPR-4505)
 they've implied that Wicket should have better bean caching (though
 they've
 fixed them anyway).

 So.. how would one go about addressing this problem? It's a big
 performance
 issue for those deploying a Wicket app using @SpringBean on multi-core
 systems. I'm able to hack around it in our app, but not knowing much

 how Spring and Wicket should be
