6.0.x Docs Down?

[William Speirs]

Am I looking in the wrong place, or are the 6.0.x docs down and have been
for almost a week now?

http://ci.apache.org/projects/wicket/apidocs/6.0.x/

An old link for the 1.5 docs is still up and working:
https://wicket.apache.org/apidocs/1.5/ But I cannot figure out how to munge
that into something for Wicket 6.

Thanks!

Re: Introducing Croquet: Combining Wicket, Jetty, Hibernate, and Guice

[William Speirs]

I hadn't heard of it. There are a few ORMs out there. I've looked at this
library as well: http://jdbi.org/ However, that's a bit too much SQL
writing for just the basic objects for me. Though it is a GREAT setup to
make unit testing REALLY easy.

I just find the JPA API so clumsy, especially when building dynamic
queries. Even Hibernate's "native" interface is MUCH better than JPA.

Re: Introducing Croquet: Combining Wicket, Jetty, Hibernate, and Guice

[William Speirs]

Off-topic a bit... on the JPA front, I'm still relatively new and finding
it not as useful as I would have hoped. Beyond VERY simple
read-by-primary-key and update/create/delete, anything else seems tedious.
I'm having to learn the JPA query language (yes, you can use SQL but then
you lose generics/typing). I'm highly considering updating another one of
my projects SOP4J-DBUTILS (https://github.com/wspeirs/sop4j-dbutils) to
handle JPA annotations for the basic CRUD operations, then just making it
slightly easier to use complex where clauses to populate POJOs.

Thoughts?

P.S. We should probably take this off the Wicket list if folks want to
continue discussing...

Introducing Croquet: Combining Wicket, Jetty, Hibernate, and Guice

[William Speirs]

I gave a talk at ApacheCon NA yesterday on Croquet. It is a combination of
Wicket, Jetty, Hibernate, and Guice to make it super-easy to start writing
Wicket code almost immediately, instead of spending time configuring
everything.

Re: Wicket + Guice + Transactional

[William Speirs]

Thanks for the idea... it worked! However the only hitch now is that I'm
force to use field injection which makes unit testing that much harder (I
really like everything constructor injected).

I guess what I'd need to do is have my Guice binding be to a @Provides
method which constructs a proxy class so that everything can be properly
injected and serialized. Any thoughts on how I'd go about doing that?

Wicket + Guice + Transactional

[William Speirs]

I'm using guice-persist (
http://code.google.com/p/google-guice/wiki/GuicePersist) with Wicket and
trying to construct a SortableDataProvider that leverages Guice's
@Transactional annotation on the methods that read from the DB. In my page
I pass this SortableDataProvider to a DataTable which down the line sets a
field in a DataViewBase to this SortableDataProvider:

private final IDataProvider dataProvider;

When Guice constructs this SortableDataProvider it rewrites (creates new?)
the class using CGLIB and adds a field of type
com.google.inject.internal.InterceptorStackCallback to my
SortableDataProvider. Unfortunately, this type is not Serializable and
looks like it never will be:
https://code.google.com/p/google-guice/issues/detail?id=12

I see a few options for "solving" this problem:

1) The IDataProvider field in the DataViewBase could be marked as
transient getting around the issue that InterceptorStackCallback isn't
Serializable.

2) I can remove the @Transactional annotation from my methods. This way
Guice does NOT rewrite (create a new) class that adds an
InterceptorStackCallback field.

So my questions are:

1) What are the chances that DataViewBase could be updated to mark the
IDataProvider field as transient?

2) Does anyone know the implications of NOT marking my methods as
@Transactional? I'm only doing SELECT statements in the code, and the
EntityManager is bound to the request. I'm just familiar enough with JPA
(Hibernate is my provider in this case) to be dangerous :-)

3) Is there anything else I can do?

Thanks!

The actual Initializer.properties files aren't an issue as they are in
different locations. However, Wicket never finds them, so they're never
loaded.

The more I think about this, the more I think there are only 2 solutions
for creating a shaded jar with Wicket and Wicket-Extensions:

1)  Come up with a non-colliding way of telling Wicket about Initializers.
Maybe something like wicket-*.properties. So I'd have
wicket-core.properties, wicket-extensions.properties, and
wicket-devutils.properties.

2) Use the Appending Transformer, but modify Wicket so it can handle
multiple initializers in a single wicket.properties file.

Thoughts?

Calling them is one thing, but that's actually not enough. It appears I
also have to add the string resources. (That is where I was really getting
tripped up.)

I guess my real question is, what else am I missing?

Would this be considered a bug? Couldn't we have Wicket look for a single
combined Wicket.properties file, and load everthing accordingly?

I cannot be the only one trying to create a shaded JAR... how have others
solved this?

Multiple wicket.properties files in uber JAR

[William Speirs]

I'm attempting to create an uber JAR using the Maven shade plugin and
running into an issue shading wicket, wicket-extensions and
wicket-devutils. All 3 of these module contain a wicket.properties file
that point at their respective Initializers. The problem is that when I
create the shaded JAR, the wicket.properties files all want to live in the
same place and overwrite each other. I can combine them into a single
wicket.properties file, but when the properties are loaded
via addInitializer(properties.getProperty("initializer")); only the last
one in the file is used.

Has anyone ever created an uber JAR with wicket and wicket-extensions (I
can drop wicket-devutils if needed)? If so, how did you do it?

If I needed to hack this together, knowing the names of the Initializers,
can I call them "manually"?

Thanks...

Re: clustering and failover

[William Speirs]

Another consideration is if you're using any authentication that
relies upon the tomcat session, then bouncing to another box (if
you're doing round-robin load balanced) would mean your users will
have to reauthenticate.

Been there, still have the bite marks from that :-)

Re: DI Through Constructors w/Wicket

[William Speirs]

I'm just getting to this now... weekend coder.

@MartinGrigorov - this looks exactly like what I want, or parts of it
at least... I'll certainly check it out. And you're right, I shouldn't
be so skeptical, you Wicket folks seem to always come through with
some library when I ask a question :-)

@DanielWatrous - your blog is helpful, except that you instantiate a
Guice instance in your unit test. I'm still wrestling with what I
consider "best practices" with respect to Guice/DI and Unit Tests, but
I'm strongly leaning towards the best practice of: If you're having to
create an injector in your unit test, then you're doing it wrong.

Dependencies should come in through the constructor and constructor
only. In the unit test, mocked instances of those dependencies should
be passed in through the constructor after you've called new to create
the object itself. This ensures you're ONLY testing the object, and
none of its dependencies in that unit test. If you cannot pass your
dependencies through the constructor, it's most likely because you're
not letting the framework create the instance for you, and this
exposes a deficiency in your implementation. This is the problem with
Wicket, it creates the pages for you (unless you implement your own
IPageFactory like in the library Martin linked), which forces you to
use field injection like you did in your blog example.

Draconian "best practice"? Maybe, but when working with a number of
developers on a project, I find it best to keep strict but simple
rules; even better when they can be enforced with things like
Checkstyle.

Am I totally wrong here? Am I missing something? I'd love people's

DI Through Constructors w/Wicket

[William Speirs]

I think I know the answer before I ask, but is there any way to do
constructor injection with Wicket? Say I have a web page and an email
service. I need the email service in the web page. Now everyone is
going to say, "Simply use field injection." That will work, but makes
unit testing a real pain because now I have to setup injection for my
unit test (or add additional methods to all of my pages so I can
manually set these field, or additional constructors that set these
fields). I should be able to unit test a class without needing
injection, but instead passing mocks through the constructor.

I feel like this is impossible in Wicket currently because the
DefaultPageFactory is using reflection to create the page instances
instead of the injector (Guice in my case). It would be easy enough to
get the injector and call getInstance() to obtain a page instance. The
problem is when you need to pass in parameters. There is no concept of
parameters for a page other than what is passed via the constructor,
so you cannot call something like setPageParameters because it doesn't
exist. If using Guice, you could create an @Assisted injection, and
have a factory.

Has anyone tried creating this type of IPageFactory -- a
GuicePageFactory? What kind of pitfalls would exist if I attempted
such a thing? Am I being stupid and missing something? Thoughts?

Thanks...

That's actually where I started, but they only support providing a list of
choices up-front instead of the callback. I was able to get the callback
working and with less StringBuilder hacky code by using
a separate javascript file and TextTemplate as suggested by Martin Grigorov.

I also tried to get the AutoCompleteTextField[1] component to work with
Bootstrap, but couldn't figure out how to make all the CSS happy. Someone
more familiar with both projects could probably pull it off though, and
that would make a nice addition to Wicket or wicket-bootstrap by the Apache
foundation [2].

Thanks for everyone's help...

Attaching Ajax Function to Java Method

[William Speirs]

I'm trying to create a typeahead component for Wicket that uses Bootstrap's
Typeahead:

To set this up though I need to provide the .typeahead method in JavaScript
with a function that will return the results, given the query. What I'd
like to do is attach that JavaScript function to a Java method much like
what is done with an AjaxEventBehavior [2]. I cannot figure out how to go
about setting all of this up... any ideas?

Thanks...

Re: NumberTextField Issue

[William Speirs]

OK... so it's not Wicket related, it is a combination of Bootstrap + Chrome
+ HTML5. This blog post I found actually explains it quite well:
http://blog.isotoma.com/2012/03/html5-input-typenumber-and-decimalsfloats-in-chrome/

The short version is that there is a step attribute when an input's type is
number. If you don't specify a step then it defaults to 1 making decimal
values invalid. As soon as I set step="0.01" it worked like a champ (I did
that because it's a currency, but you can also set step="any").

Coming back to Wicket, since the NumberTextField component has the ability
to setMaximum & setMinimum, should it also have a setStep method? Otherwise
you're forced to use a combination of Wicket methods & HTML attributes to
control the input box.

Thoughts?

Re: NumberTextField Issue

I'll need to double check and get back to you, but I think it might be a
bootstrap issue. The input box gets styled with controls to increase and
decrease the number and that might be the issue.

Re: NumberTextField Issue

[William Speirs]

I tried that and get the following:

Component must be applied to a tag with [type] attribute matching [number],
not [text]

So it really wants it to be a number... just not sure why it won't accept
decimals.

Thanks...

NumberTextField Issue

[William Speirs]

I'm trying to use a NumberTextField with a type of Double and the form will
only let me type in integers (or doubles that end in .0). Is this a known
issue? Is there a workaround?

My basic code...

*Java*
private IModel doubleModel;

final NumberTextField d = new NumberTextField("d",
doubleModel, Double.class);

d.setMinimum(1.0d);
d.setMaximum(1000.0d);
d.setRequired(true);

form.add(d);

*HTML*

  
Double

  

  


Am I using the wrong component or HTML input type or something? Every time
I type in a number like 5.5 and try to submit the form I get the pop-up
that say, "Invalid value."

Thoughts?

Thanks...

Re: Eclipse or IntelliJ

[William Speirs]

I've always used Eclipse and am currently using Juno. The Maven support got
much better, but other stupid things seem to have "broke." For example,
switching tabs into the XML editor (or pom editor) seems to require
calculating Pi to 10 million digits each time. Actually, I think there is a
memory leak somewhere and its just a GC going off, I should load it in
VisualVM and see. There are other annoying things about Eclipse with
respect to settings, but they can usually be "fixed" by editing some file
in the .settings directory.

Tried IntelliJ once and it was terribly slow (and looked a bit ugly on
Linux)... maybe I should try 12?

At the end of the day... anything's better than vim/emacs :-)

Re: Style Modifier

@Paul Bors I would normally do the same type of thing, but I found myself
in a situation where I needed to style the background color of a div that
is dynamically loaded from a DB. ie, the user is free to chose whatever
color they want for the div's background.

A quick modification of the style element was useful here...

Style Modifier

[William Speirs]

I created a Behavior the other night that allows one to modify the style
attribute of a tag by easily adding or removing a CSS property. Why is this
better/different than AttributeModifier? Because you can update a CSS
property inside the style attribute. Basic usage:

myComponent.add(new StyleModifier("background-color", "blue")); // changes
(or adds) the background-color property of the style tag on this component
to blue

myComponent.add(new StyleModifier("background-color")); // removes the
background-color property from the style tag on this component

Would anyone else find this useful? Would the devs on this list consider
taking it in for the next release of Wicket (if so I can open an JIRA)? Is
this already implemented and I'm just too stupid to have found it?

Thanks...

Re: How to set up GuiceWebApplicationFactory and the Guice Servlet scopes

[William Speirs]

I used the GuiceWebApplicationFactory as follows in my web.xml:

  my_project

MyProjectFilter

org.apache.wicket.protocol.http.WicketFilter


applicationClassName
com.myproject.Application


   applicationFactoryClassName

 org.apache.wicket.guice.GuiceWebApplicationFactory


   module
   com.myproject.GuiceModule


   wicket-guice.stage
   PRODUCTION


configuration
deployment




Then in the GuiceModule I link up the important bits:

@Override
protected void configure() {
bind(WebApplication.class).to(Application.class);
}

I haven't used @SessionScoped or @RequestScoped at all so I cannot help
with that. Otherwise, everything works as expected...

Re: FormComponentPanel & onchange Events

[William Speirs]

I finally got some time to test a few combinations:

- onchange for panel, getRawInput() = null
- onblur for panel = event never fires

- onchange for field, getRawInput() = null
- onchange for field, getModelObject() = null

- same combinations as above but with AjaxFormComponentUpdatingBehavior;
always null

So just about all combinations still seem to only return null :-(

I put the code for my FormComponentPanel up on pastebin:
http://pastebin.com/AMvYbv2B

Any insight would be great.

FormComponentPanel & onchange Events

[William Speirs]

I've created a FormComponentPanel with 2 text boxes: A & B. I've add this
new FormComponentPanel to my page twice: 1 & 2. What I'd like to have
happen is when I change the value of 1A I want that same value copied into
2A.

I call setOutputMarkupId to true on 1A, 1B, 2A, and 2B. I setup
an AjaxEventBehavior on panel 1 and it fires as expected. However, inside
of the onEvent method all of the model instances I try to obtain are always
null (therefore preventing me from setting 2A). I've tried getting the
form's model object, the model object for panel 1, and even the model
object for A1... everything is always null.

Is there some method of FormComponentPanel that I'm not overriding that I
need to be? Any thoughts on how to make this work?

Thanks...

Re: Recommended way to hide and show table rows dynamically?

Re: problem with editable datatable

When I've had to do this, I usually use a fragment. It keeps all the HTML
on a single page and is a bit cleaner I think:

Pages, Panels, and Dependency Injection

[William Speirs]

I'm having trouble understanding how to inject components into a page so
that the page will be easy to unit test later. Say I have a page that
contains two panels. I can easily use constructor injection to inject these
panels into the page:

class MyPage extends WebPage {
@Inject
public MyPage(PanelA a, PanelB b) { ... }
}

The problem is that all Panels require an id during construction.[1] How do
I supply the id to my Panels? I could simply construct every PanelA with an
id of "panela" and every PanelB with an id of "panel", but that doesn't
seem very flexible. What do other people do in this situation? The hope
would be to pass mocked panels into the page during unit testing,
the separately test each panel.

What if instead of a panel it was a button where the onSubmit method must
be specified by overriding the method. How does one go about injecting such
a component so that it's still easy to test later in unit tests?

All thoughts and/or best practices are greatly welcomed. For reference I'm
using Guice as my dependency injection framework and
GuiceWebApplicationFactory to inject components into pages.

Thanks...

Re: Dynamically Toggling a Details Row in a DataTable

[William Speirs]

Paul-

Thanks again for all your help. As an FYI, your image didn't come
through. Not sure if you forgot to attach it, or if they aren't
allowed on the mailing list.

I should have mentioned from the start that I was looking to keep this
generic/reusable. I have an implementation working and it doesn't feel
too clunky, so I think I'm on the right track. You can find all of the
code here https://github.com/wspeirs/wicket-details-table/ and the
relevant bits here
https://github.com/wspeirs/wicket-details-table/tree/master/table-test/src/main/java/org/apache/wicket/extensions/markup/html/repeater/data

In the end I extended the DataTable so that I could modify the html
source and add a details row for each repeated row. I created a new
type of column (well two actually) AbstractDetailsColumn which extends
IColumn. This column takes care of implementing the populateItem
method so long as you provide implementations for getDetailsComponent
and getCellComponent. These two methods do exactly what you think they
should/would do. Using an implementation of the AbstractDetailsColumn
you will get a details column which is displayed default for each row
in the table. If you'd rather that column toggle its visibility (my
original request), then you can use the TogglingDetailsColumn class
which adds in the few extra calls to setup an AJAX call to set the
visibility. The implementer of getCellComponent will have to setup the
toggling in whatever AjaxComponent they pick.

Could those of you on the mailing list with more internal development
experience provide some feedback? This is my first project extending
Wicket in any serious way, and I'd eventually like to file a JIRA
ticket and get this into the next release of wicket-extensions if
they'll take it.

Thanks in advance, and I hope this helps others in the future!

Re: Dynamically Toggling a Details Row in a DataTable

[William Speirs]

Paul-

I've modified my DataProvider to provide double the rows. I've also
extended DataTable to set display: hidden on the details row and also to
expand the first column to all of the columns.

The main issue I'm having now is linking the button (in say the first
column) to something which can change the attributes of the cell. I guess
my main question is, what should control the stat of if a details row is
hidden or not?

Dynamically Toggling a Details Row in a DataTable

[William Speirs]

I would like to create a component that generates an additional row in a
DataTable for each existing row. This additional row will contain "details"
for the above row. I would like to have a column in the DataTable that
contains a link/button/etc which controls the visibility (display: hidden
for that row) of the details row. Inside the details row, the colspan would
be set to the # of columns and contain an AjaxLazyLoadPanel such that when
the row is displayed the getLazyLoadComponent() method is called,
generating and fetching the proper component.

So the DataTable will look like a normal DataTable, except when you click
the link/button/etc a new row is shown and displays the Component returned
from the call to the getLazyLoadComponent() method.

How would I go about implementing this type of DataTable?

Thanks in advance...

Group Select with Beans

[William Speirs]

I have 2 JavaBeans A & B. A has 2 fields: String name, Integer b_id. B has
2 fields: Integer id, String display.

I have a list of beans for B:
1, "foo"
2, "bar"

I have a single A bean, where its b_id corresponds to an id in bean B
(basically the beans represent 2 tables in a DB with the ids as references
to each other). I want to create a form to edit bean A which includes a
drop-down for all the possible options for bean B. The one hitch is that I
want groups for my drop-down, so I believe I'm forced to use Select &
SelectOption with the appropriate mark-up in HTML.

I have the form completed and working for changing A's name field, but I
cannot figure out how to link the drop-down which displays all my options
for bean B to A's b_id field. I'm using a PropertyModel to modify A's name
field, and but I missing how to link A's b_id to the id from B. Also, my
 has values like option3, option4, option5... I would think I'd
need these to be B's id field values for this to work.

Any help in the right direction would be greatly appreciated. I'm very
close, just missing this one link between my two models.

Thanks in advance...
