Re: [ANN] wicketstuff-lazymodel

[Jesse Long]

Hi All,

Please can we do a 6.6.0 release of wicketstuff... I'd love for 
LazyModel to be on Maven Central.


Thanks,
Jesse

Hi all,

I've added a new module to wicketstuff:

LazyModel offers lazy evaluation of method invocations. It takes the 
best from present solutions (safemodel and modelfactory) and improves 
on reflection to support:


* arbitrary parameters
* generics
* collections
* interfaces

Two simple examples:

IModel model = model(from(a).getB().getStrings().get("key"));

new LazyColumn(header, from(A.class).getB());

Read more here:

Have fun

If the FileUploadField is just a FormComponent> shouldn't 
calling setRequired(true) on it and submitting the form with blank user input 
generate an error using the "Required" language pack key?

I've notice that it doesn’t do that for me and was wondering if it's just me.

Re: JS execution order problem

 Im having a problem with Javascript execution order that I could use
 some
 help with.  I made a quickstart here:
 https://dl.dropbox.com/u/**107816727/quickstart.tar.gz

 Basically, this is a Wicket DefaultDataTable, with an embedded
 AjaxEventBehavior, overlaid with a Datatables.net JS behavior (
 www.datatables.net).

 What seems to be happening is that the Datatables.net JS is executing
 before the Wicket AjaxEventBehavior JS, and in so doing, it paginates
 the
 table and removes a couple of IDs that Wicket then cannot find.
 I thought the default JS execution order was children first, then
 parent,
 so I was expecting the AjaxEventBehavior JS to execute first and then
 the
 Datatables.net JS (which is on the parent DefaultDataTable)

 To reproduce simply click any of the "Click Me" cells in the table.

 Any suggestions would be most appreciated,

 Regards

 Nick

Re: Validator Question

[Jered Myers]

Assuming you are extending AbstractFormValidator, you can store the 
components when you construct the validator like so...


public DependantTextFieldValidator(TextField textField1, TextField 
dependantTextField)

{
if (textField1 == null)
{
throw new IllegalArgumentException("argument textField1 
cannot be null");

}
if (dependantTextField == null)
{
throw new IllegalArgumentException("argument textField2 
cannot be null");

}
components = new FormComponent[] { textField1, 
dependantTextField };

}

and then pull them back out like so...

public void validate(Form form)
{
// TextField1
final FormComponent textField1 = components[0];
// DependantTextField
final FormComponent dependantTextField = components[1];

boolean textField1Empty = Strings.isEmpty(textField1.getInput());

}

The Validator is Form-level because it is multi-component; it must work
generically on any pair of Component IDs, because it's shared between
different projects. Right now the implementation is:

@Override
public void validate(Form form) {
//...
}

The issue is that I can't pass any arbitrary pair of IDs to validate, the
param is a Form. Do I hard-code all the possible IDs that different projects
can use? Or is there a better way to do it?

Re: Wicket Tester with BookmarkablePageLink

[yka]

Hi Vineet,
tried it out. My setup() method now looks like this:

@Before
public void setUp() {
MockitoAnnotations.initMocks(this);
app = new StartApplication() {
@Override
public ServletContext getServletContext() {
ServletContext servletContext = 
super.getServletContext();
ApplicationContextMock appctx = new 
ApplicationContextMock();
Service service = Mockito.mock(Service.class);
appctx.putBean(service);
WebApplication application = new 
MockApplication();
WicketTester tester = new 
WicketTester(application);
SpringComponentInjector componentInjector = new 
SpringComponentInjector(
tester.getApplication(), 
appctx, false);


tester.getApplication().getComponentInstantiationListeners()
.add(componentInjector);

return servletContext;
}
};

org.apache.log4j.Logger logger = org.apache.log4j.Logger
.getLogger("org.apache.wicket.util.tester");
logger.setLevel(Level.DEBUG);

tester = new WicketTester(app);
}

Wicket 1.5.x FileUploadField and the required flag

If the FileUploadField is just a FormComponent> shouldn't
calling setRequired(true) on it and submitting the form with blank user

I've notice that it doesn’t do that for me and was wondering if it's just

The following might work.

1-Put data in a hidden field.
2-Use wicketAjaxPost() to stream back this value to server side.

Re: using static fileds in a page

[Jochen Mader]

If you are already using Spring why do you need the field to be static?
Beans are by default singleton scoped and can be tailored to
session/request scoped.

Re: JS execution order problem

[Nick Pratt]

I take some of that back:

In the initial page rendering, the Javascript is ordered as I expect (child
JS then parent JS).
However, in the Ajax update, the Wicket listeners are added *after* the
datatables init call, which results in an out of order sequence.

Why is the Ajax update change the order of the JS of the parent and child
elements?

Re: JS execution order problem

[Nick Pratt]

Thanks - that seems to confirm the problem - delaying the Datatables JS to
after the Wicket link listeners have executed will fix it, since the errors
are coming from the Wicket Link Listeners not being able to find markup IDs
that the Datatables JS paginates out of view. (load fires after ready if my
research is correct)

I expect the execution order to be:
1. All link listeners within the table would be executed (all rows in table
are available at this point)
2. Datatables JS then executes and paginates the table

Although when I look at the page source I see the Wicket event listeners
listed before the Datatables JS, they seem to be executing in a different
order - this is what is confusing.

Re: Sending Data via Javascript and AJAX

[Nick Mudge]

Looks like the problem with AjaxEditableLabel is that it sends data to the
server through a URL. The data I need to send to the server is a lot of
data and won't fit in a URL.
Is there another source code example that I could look at that can send a
lot of data to the server via AJAX?

Here's is what I need to do:
I have a web page with a Save button on it. When the user presses the Save
button I want to execute some javascript which generates a large string
value and then I want the value to be sent to the server where I store the
value in a database. Then I want a label to appear on the webpage that says
the data has been saved. The string value contains a lot of data and so the
value cannot be put in a URL.

I am using Wicket 1.4.

Thanks
Nick

Re: JS execution order problem

[Andrea Del Bene]

Replacing OnDomReadyHeaderItem with OnLoadHeaderItem (class 
DatatablesBehavior) seems to solve your problem. It's likely that your 
script (the one from DatatablesBehavior) depends on some other code and 
it must wait for it to be loaded before being executed.

Im having a problem with Javascript execution order that I could use some
help with.  I made a quickstart here:
https://dl.dropbox.com/u/107816727/quickstart.tar.gz

Basically, this is a Wicket DefaultDataTable, with an embedded
AjaxEventBehavior, overlaid with a Datatables.net JS behavior (
www.datatables.net).

What seems to be happening is that the Datatables.net JS is executing
before the Wicket AjaxEventBehavior JS, and in so doing, it paginates the
table and removes a couple of IDs that Wicket then cannot find.
I thought the default JS execution order was children first, then parent,
so I was expecting the AjaxEventBehavior JS to execute first and then the
Datatables.net JS (which is on the parent DefaultDataTable)

To reproduce simply click any of the "Click Me" cells in the table.

Any suggestions would be most appreciated,

Regards

Nick

Exactly!
Note the '$1' in the class name. This means the class is an anonymous class
in ExtGrid.
Just use ExtGrid.class instead of this.getClass()

Re: JS and CSS package references

[Entropy]

That's exactly what i am doing.  Notice the comment marks /* and */ around
the package stuff.  I tried it both ways.  And "this" in this case is
ExtGrid.java.  So I am also sending in that class.

So I have to pre-register these resources in some way or something?  Note
that ExtGrid is a panel not a page, so the resources aren't in the same
pacakge as the page.  Would that matter?

Hi,
Why would I look at the AjaxEditableLabel? According to the javadoc for it,
it is for: "An implementation of ajaxified edit-in-place component using a
TextField as it's editor."
I am not doing that.

What I need is a Save button that executes some javascript to calculate
some data that is then sent the server via AJAX.  Then I need to update a
label on the webpage saying that the data has been saved.

How can I do this?

Thanks
Nick

RepeatingView and FormComponentPanels

[Lucio Crusca]

I've created three subclasses of FormComponentPanel, e.g. 
TextFormComponentPanel, CheckBoxFormComponentPanel and 
DropDownChoiceFormComponentPanel. They all share some markup logic in that 
they all have an enclosing  and a  for the text to use as label. 
However each class has its own markup file, because each one needs a different 
 or  instead. Here is for example 
TextFormComponentPanel  markup:


  [label text]




Then I created a FormComponentPanel derived class that uses a 
RepeatingView, and expects its derived classes to fill in the RepeatingView 
with instances of the three classes above. Those derived classes are the 
detail forms corresponding to my domain model beans.

The problem is that TextFormComponentPanel, CheckBoxFormComponentPanel and 
DropDownChoiceFormComponentPanel html markup have fixed IDs for the input tags 
(I mean html id attributes, the ones referenced by

Maybe you can monkey patch wicketHide and wicketShow? Make some assumption
that indicator id start as "ind_" and then do an special "delayed" show for
those DOM elements/

Ajax indicator - display delay

[Daniel Stoch]

Hi all,

When there is some AJAX activity on page we can show ajax indicator
(using AjaxIndicatorAppender and implementing IAjaxIndicatorAware).
My problem is that I want to show such indicator only when ajax
request takes longer than specified amount of time (eg. > 1 second).
But inside a AbstractDefaultAjaxBehavior (1.4.x) such indicator is
shown immediately when request is processed. Is there any solution to
delay displaying indicator (something like AjaxCallThrottlingDecorator
but not for ajax beahvior but for ajax indicator itself)?

How are you ensuring that the thread that created the page is the same one

Re: using static fileds in a page

If you create an ExecutorService then you should shutdown it too.
See org.apache.wicket.Application#getApplicationListeners &
org.apache.wicket.IApplicationListener#onBeforeDestroyed
or org.apache.wicket.Application#onDestroy

Re: using static fileds in a page

[Martin Grigorov]

Hi,

Since it is static it wont be (de)serialized at all.
But it will be used by *all* instances of this page. Is this OK for your
case ?

using static fileds in a page

[fachhoch]

to run my lengthy  operation, my pages needs, I am using a static filed which
is a proxy  of my service in the page class itself, on ahjaxevent I use this
proxy to get my data, this proxy times out based on configration to avoid
wicket  freezing for lengthy operation.

Is it advised to have static field in page? Its not instance data so will
they be serialized ?
Please clarify will this cause issues  with   page serialization and
denationalization?

Re: ThreadLocal with ajax

[Martin Grigorov]

Hi,

Why do you use ThreadLocal ?
Each http request is handled by a random thread from the web container's
thread pool.
You should store that value in the session if you want it to be available
in the next request.

ThreadLocal with ajax

[Ann Baert]

Hi,

I have a springbean with a ThreadLocal property. On the page (constructor
and onBeforeRenderer) I set a value to that ThreadLocal property. When I do
the get of that property after an ajax call, the value is null.

I made a quickstart to simulate the problem. I print the ThreadLocal value
on the page (correct) and
after call on the ajaxlink the value is null.
Does anyone know a solution for this?

Re: Sending Data via Javascript and AJAX

[Martin Grigorov]

Hi,

Take a look at AjaxEditableLabel, it sends a parameter named "save".
This is improved a lot in Wicket 6.
