Is this safe?

2008-01-21 Thread Martijn Lindhout
Hi all,

I wonder if this will work:

add(new CartPanel(cart, new PropertyModel(s, cart)));

where 's' is my app specific session, containing the method getCart() which
checks the session for an existing cart, and if not found creates one.

Is this enough to handle load/detach? Or do I have to write my own
LoadableModel

RE: We are adopting Wicket in our Organization

I fully agree. I used JSF/SEAM before switching to Wicket.
My experience is that Wicket is JSF-Done-Right



As I've stated before in a previous post, I work a for a company that
develops software for the health care industry.  It was a battle between
JSF/Seam and Wicket as the framework of choice for the rewrite of the
company's portal.  After a whitepaper written by a colleague of mine that
compared the two implementations, Wicket was the clear winner. (I also
presented a demo of the Wicket framework to the team a couple months back).

I'd like to thank the authors of the framework for building such a fine
tool.  After years of struts development, developing web applications with
Wicket is a breath of fresh air.  Keep up the fine work.

I'll update this forum with our experience in developing/deploying web apps
using Wicket.

Link to last version of a page of a given type/class.

2008-01-21 Thread Ned Collyer

Hi,

I may be overlooking something, however I am having a bit of trouble linking
to the last current version of a page unless I use the method outlined by
igor, which isn't practical for what I am trying to achieve (see his method
below from
http://www.nabble.com/pageMap-question---td13541168.html#a13554232)


igor.vaynberg wrote:
 
 for scenarios like those simply pass the page instance to another page
 
 class secondsteppage extends webpage {
   public secondsteppage(page first) {
 add(new link(go-back) { onclick() { setresponsepage(first); }});
   }
 }
 
 -igor
 

For example, say I have a page of search criteria (the form is in a reusable
panel), and its filled and i navigate around a bit.  The next time I come to
the search criteria page, I want it to remember the last search (ie, return
the last version of the search criteria page).

I have been able to do this in a rudimentary way by passing the page
instance of the search criteria page through to the constructor of the
destination page via a forms onSubmit().

This means I can then call the
setResponsePage(searchPage.getVersion(Page.LATEST_VERSION)); on the onClick
of a link in the destination page.

However this will only work from the destination page - not if i navigate
around to other pages.  Without specifying a version  a new instance is
being created.

 (ie PageLink(SearchPage.class) creates a new SearchPage instance).

Surely there is a way of retrieving the latest existing version of a page
given a class type.  I've trawled google and the examples and api - I'm
feeling stupid - like i've missed something obvious, or inadvertently broken
the expected behaviour.

Just remember  in a simple valuesholder class the page id and pagmap
for a page (and version if you want that) and then ask through the
session for that page. If many pages (or big pages) are created in
between, it could return nothing.. Depending on the size of the
diskpage session/pagmap file.

Can some official Wicket buttons be made available to add to sites and

The Spring Framework buttons can be found here:

Oh and by the way I noticed a poll on the Spring front page:

Re: Link to last version of a page of a given type/class.

2008-01-21 Thread Ned Collyer

Hi Johan,

Thank you for the reply.

This suggestion will work, but it seems like something that the framework
should do automatically.  The whole maintaining state thing is meant to
maintain state between requests without the extra dev overhead of manually
plugging stuff into, and pulling out of the session.  I'm happy to get a new
instance of the page if its been cleansed from the session - thats not a
problem, but I was under the impression that wicket should already be
maintaining this state - I just need a link generated.

I find it a bit bizarre that methods like Page.getVersion(int num) exist,
but because its not static.. i need an instance of the page to retrieve a
previously versioned instances of the page. (rather than
Page.getVersion(Class clazz, int version)).

Does wicket not support linking to the last version of a given class type? 
If not, I would find this quite useful.

Something like

new PageLink(search-criteria-link, SearchCriteriaPage.class,
Page.LATEST_VERSION)

Would be exactly what I'm after.  (I'm still optimistic that this feature
exists and its me being stupid not able to find it. ;))

Typically a custom request cycle for the actual object and store the key for
getting access to the object in the session.
If the cart is not a hibernate entity, but something really transient, I
don't think there is any harm in putting it in the session, as long as you
are certain you won't be doing resouce updates based on the session.
Typically add/remove from carts are single requests that are synchronized on
the session.

As for the property model, you can do this as well:

add(new ShoppingCartPanel(panel, new PropertyModel(this, session.cart

Re: Questions for permission of using the design of wicket-example

Actually, Wicket as it pertains to Apache Wicket is protected. I'm just
not sure to what extent. It may even be that new open source projects many
not call them WicketFoo, but rather Foo for Apache Wicket. It all has to
do with protecting the trademark.
However, I'm still waiting for a reply from the PRC.

  people join with us.
 
https://sourceforge.jp/projects/wicket-ja
 
We are creating the group-site now (we haven't it yet. only mailing
  lists).
 
The wicket framework is so hot now in Japan! We would like to expand
  the number of users in japan by providing wicket-related information
  to our members in japanese language and at some time would like to
  contribute to the Apache Wicket project by sending you some bug-fixing
  or function-expanding code.
 
We have some questions to the wicket team. and I could not find out
  the contact address on wicket site. I hope that the members of wicket
  team will read this message...
 
Our questions:
 
1. We would like to make our pages visually 'wicket-like'. So we
  would like to use the design and background images of your 'wicket-
  example' like http://www.wicketstuff.org/wicket13/captcha/ . May I do
  that?
 
2. Can we use your Wicket Logo mark on our site? or is it under any
  kind of protections? If it is possible, we would like to put the logo
  mark on our top page.
 
 
 
Thank you.

You might want to skip the packaged version (IMO linux packagers don't get
the Java packaging), and just unzip a tarball in /opt/tomcat/tomcat-5.5.20
Then you are in complete control over how the server runs.

 dream of a seamless, fire-and-forget, auto-deploying, smoke-tested,
 pluggable and modular web app deployment system.


 Any ideas on how to better configure Tomcat?

Well not exactly, the poll question I am referring to for web templating
has JSP, Velocity, FreeMarker, GWT, JSF, Tapestry, Wicket and Others are
the choices.

But you have a point - Spring MVC developers would have to choose between
JSP, Velocity or FreeMarker and sure enough - JSP has an impressive lead.
JSF comes in as a clear second though.  This must be the Spring WebFlow

Re: Link to last version of a page of a given type/class.

2008-01-21 Thread Johan Compagner
Wicket does maintain state, but what you want is something different
and currently not supported. We dont have 'static' pages for a
specific page class. You are in full control.

About pag.getversion those methods shouldnt be used by users of wicket
at all. If you want something like this because you dont want to keep
references to the pages itself use session.getPage method

On 1/21/08, Ned Collyer [EMAIL PROTECTED] wrote:

 Hi Johan,

 Thank you for the reply.

 This suggestion will work, but it seems like something that the framework
 should do automatically.  The whole maintaining state thing is meant to
 maintain state between requests without the extra dev overhead of manually
 plugging stuff into, and pulling out of, the session.  I'm happy to get a
 new instance of the page if its been cleansed from the session - thats not a
 problem, but I was under the impression that wicket should already be
 maintaining this state - I just need a link generated.

 I find it a bit bizarre that methods like Page.getVersion(int num) exist,
 but because its not static.. i need an instance of the page to retrieve a
 previously versioned instances of the page. (rather than
 Page.getVersion(Class clazz, int version)).

 Does wicket not support linking to the last version of a given class type?
 If not, I would find this quite useful.

 Something like

 new PageLink(search-criteria-link, SearchCriteriaPage.class,
 Page.LATEST_VERSION)

 Would be exactly what I'm after.  (I'm still optimistic that this feature
 exists and its me being stupid not able to find it. ;))

I know from first hand experience with a couple Linux distros are still

Re: Ext JS, form submit

2008-01-21 Thread Murat Yücel
Hi Flemming

I have also tried to integrate ExtJS and wicket, but i dont think it is
possible if you need to post
or edit content on a page. The best way to post a form is to use xml between
ext and wicket
but then it doesnt makes sense to use wicket.

Wicket needs markup, ext doesnt have any markup, thats why you can only use
readonly ext
widgets.

Maybe the wicket team should do the same as google. Talk with the ext devs
and make
and integration.

/Murat

2008/1/18, Flemming Boller [EMAIL PROTECTED]:

 Hi


 Having glazed at the ExtJS components you can not help, but feel I must
 try
 and integrate this into wicket.

 However  when I started at  trying to submit data to  wicket from the
 Ext.form.FormPanel, lots of trouble appeared.

 I can not make Ext.FormPanel apply to  a form tag , only a div tag.
 With
 div tag I can not in wicket use the Form Component.

 Also the id´s of elements change after Ext.onReady() has been performed,
 which I think is not good for wicket :-)


 Anyway the million dollar question is: Has anyone made a successfully
 'form' submit from Ext to a wicket component ?

 Flemming



Re: Security violations and ERROR: filterStart with Tomcat deployment on Debian Etch

2008-01-21 Thread Martijn Dashorst
I think that most linux packagers don't work with Java projects and do
whatever they like. What Daniel is experiencing is an overzealous packager
that shuts down the most basic service tomcat needs to provide: run a web
application that does more than serve static pages. Packagers often make any
documentation that is available for a Java project worthless because they
move everything all over the disk.
This is akin to a mysql installation where you can't start a database and
run queries against.


Also, AFAIK 5.5.20 is about 1.5 years old. To me that is an indication that
packagers don't provide the most secure and workable solution, especially
when the latest 5.5.x (5.5.25) is already 6 months out.


Conservatism is a great thing for production servers, but running 1.5 years
behind the curve...?

Of course, the converse could be said for Java developers not getting linux
packaging, and in a sense we can learn a great deal from the tried and
tested unix package management. But even that is something that is still
evolving. For instance maven's repository infrastructure could (should?) be
pushed to a RPM/jpackage/apt service. The way I see it is that maven has
reinvented the wheel, and managed to make it a bit bumpier...

Different views in wicket

Hi!

I'm developing a site that has different views and languages. How does this
fit in the wicket framework?

When adding a WebPage you get a default .html view. Is there anyway on
having multiple views for a wicket page? How do you develop a site with same

been the biggest issue compared to more convertional approaches but I guess I 
am just not getting it well enough.

Re: RadioChoice : default choice ?

2008-01-21 Thread scottomni

Thanks for the suggestion (to hit the Java Books, further), Per.  I'm sure
that is sage advice.

However, just to clarify...
-  I am aware that RadioChoice *is* a different Type than String
   -  my question: how is a RadioChoice value converted back and forth with
a String?
-  It appears (to me) that RadioChoice is a Wicket Class (hence my question
to Wicket Forum)

Regarding Learning Path...
I am accustomed to jumping around when learning and when I came across
Wicket, it appeared to be a superior way to incorporate Java in a web
environment.  Thus, I have not studied any of the Swing stuff that most of
the books contain.  IMHO, I think Wicket would be an outstanding paradigm
from which to *teach* Java.  After all, the web is a very probable
deployment platform for new Java projects.  If Wicket *is* the *way*, I
think there is a huge opportunity to train and indoctrinate new Java
programmers, using Wicket from the get-go.  For me, what has been confusing
has been distinguishing where Wicket is deviating from standard Java.  I
sense that it could all come together quite nicely (for a java newbie), if
beginner 'Java, the Wicket Way' resources were available.

Thanks - Scott

 The cause of this is that Male is of type String and genderChoice is of

 RadioChoice. But you can't say that an apple (RadioChoice) is an (=)
 orange 
 (String).
 
 I would suggest, that you start with a good java book. Wicket is not the
 right 
 place to start learning java. It's more a good start learning 
 web-development.
  
 Hence, I don't get 
 what I need to do to display a RadioChoice (on a Form) and Get/Set the
 values (which I will be storing in a database).  Additional note: I am
 picked up 'getModelObjectAsString' from a Login Example.
 The example you should understand is here 
 http://www.wicketstuff.org/wicket13/forminput/
 There is a link in the upper right corner with source code. The classes 
 FormInput.java and FormInputModel.java should help you out.
 
 Otherwise i really appriciate that you know the java basics before you
 start 
 with wicket development. It makes it easier for everyone :-)

parse directive in velocity template failing

I am using a velocity template, and within it would like to use velocity's
parse directive (to include another template within the current template)
but it complains that it can not find the template in velocity's
TEMPLATE_ROOT.  I have triple-checked that the template is in the same

can't find a template when using parse ?

Does Wicket specify its own template location? If so, does anyone know where
the default Velocity TEMPLATE_ROOT would be?

Extend PagingNavigator.  I made a custom one so I can use everywhere:

The active page will be in Red and italics.
You can make it anything you want by changing the HTML and/or CSS. Hope it
works for you.

Java - CustomPagingNavigator.java

import org.apache.wicket.markup.html.navigation.paging.PagingNavigator;

public CustomPagingNavigator (String id, IPageable pageable) {
super(id, pageable);
}



// Second PagingNavigator constructor
public CustomPagingNavigator (String id, IPageable pageable,
IPagingLabelProvider labelProvider) {
super(id, pageable, labelProvider);
}

}

HTML - CustomPagingNavigator.html

!-- This is a customization of the wicket component PagingNavigator.html 
It changes the following defaults

Re: RadioChoice : default choice ?

2008-01-21 Thread cblehman

Scott,

To answer your last question, to set a selected value on the RadioChoice,
you must set the PropertyModel's value to what you want selected.  One thing
that took me a while to figure out personally (and I have been programming
in java for several years) is that the Object you set in the PropertyModel
must be of the same type (class) as the objects in your list of choices.  

This is what Per was referring to.  So if you have a list of Integers as
choices, set the propertymodel to an integer.  If you instead have a more
complex Object (say MyChoiceObject) for your choices you use that.  To
render the choices, Wicket by default will just do ToString on the Object
inthe choices list, unless you create an IChoiceRenderer.  In any event, you
need to set the PropertyModel's object to an object that is int he List of
choices to preselect one of the objects.  The example below is a good on,
you should look at the RadioChoice and DropDownChoice, since they both use
the same idea with their propertymodels.

The point is that at some time, Wicket will try to cast one of the objects
in the list into the variable in the propertymodel, so they have to  have
the same type.

Hope this helps...
-Clay

Re: create new model object of a Form from one of its FormComp values??

Having a bean makes things explicit. Getting stuff from a text component
directly is very read unfriendly. See it as a small investment in
maintenance. You will thank yourself later for taking the 1 minute to
generate the bean :-)
But it is all a matter of taste and one can argue about that for ages.
Whatever gets the job done and is maintainable in 2 years from now is the
winner imo. What that means for you, that is for you to decide :)

Re: Different views in wicket

wicket tries to load localized files first.

so if you have MyPage.class and you are in german locale the loading
order would be
MyPage_DE_de.html
MyPage_DE.html
MyPage.html

then there are also variations, if your page.getvariation() returns
foo then the loading order is

MyPage_foo_DE_de.html
MyPage_foo_DE.html
MyPage_foo.html
MyPage_DE_de.html
MyPage_DE.html
MyPage.html

there is also session.set/getstyle() which is just like variation but
will set the style on session-level instead of page-level.

The good thing about using beans is that you can eliminate plumbing
code. Instead of a massive copy action e.g. in your onSubmit, you can
use a bean that is already populated with the values. I often use my
domain objects directly - and I already have those objects anyway - so
I save quite a bit of dumb copying code. Not everyone agrees with
using domain objects directly though; ymmv.

 I have also tried to integrate ExtJS and wicket, but i dont think it is

 between ext and wicket
 but then it doesnt makes sense to use wicket.

 Wicket needs markup, ext doesnt have any markup, thats why you can only
 use readonly ext
 widgets.

 Maybe the wicket team should do the same as google. Talk with the ext devs
 and make
 and integration.

  I can not make Ext.FormPanel apply to  a form tag , only a div tag.
  With
  div tag I can not in wicket use the Form Component.
 
  Also the id´s of elements change after Ext.onReady() has been performed,

Btw, add(new CartPanel(cart, new PropertyModel(this,

Re: bookmarkable link keep recreate the objects.

2008-01-21 Thread Eelco Hillenius
  This is obviouly a huge performance issue.

I wonder if it is. Java is optimized for creating objects, and
creating new ones is often cheaper than reusing old ones if you take
synchronization and lookups into account.

Are you sure it is a bottleneck? If you haven't seen any actual
performance problems (and determined that it is the web tier causing
it, which is often unlikely given that accessing the back-end such as
databases often take the majority of the processing of a request)
you'd be wasting your time. Premature optimization is evil :-)

If you're still unconvinced, take a look at
org.apache.wicket.examples.staticpages in wicket-examples; it might do
what you want.

Re: create new model object of a Form from one of its FormComp values??

2008-01-21 Thread infodoc

Thanks to everyone for their comments 

Igor,

Assuming I use a bean, could you please give me a bit more detail on your
suggestion?
I want the model object of the editor Form to be the newly-created Account,
so that other objects can simply call getModelObject() on the editor like
normal and get the correct (new) value.  Do I simply set the new Account as
the model object of the editor Form?

In onSubmit(), would I code something like the following?

Account accountBean = (Account)getModelObject();  //bean updated with values
from FormComponents

Account newAccount = Account(accountBean );  //copy constructor using bean

setModelObject(newAccount);


RDC



personally i would map the form to a bean, and then in onsubmit()
transfer those properties to an instance of your domain object.

Re: RadioChoice : default choice ?

2008-01-21 Thread scottomni

Thanks Clay.  I think I have reached a point in Wicket that is providing (me)
the motivation to go 'back' to the Java Book and push forward (through the
java learning curve).  I'm getting there, slowly but surely. ;-)

In the process, it looks like I will be familiarizing myself with the Swing
library -- which, will probably enhance my appreciation (and understanding)
of Wicket.

cblehman wrote:
 
 Scott,
 
 To answer your last question, to set a selected value on the RadioChoice,
 you must set the PropertyModel's value to what you want selected.  One
 thing that took me a while to figure out personally (and I have been
 programming in java for several years) is that the Object you set in the
 PropertyModel must be of the same type (class) as the objects in your list
 of choices.  
 
 This is what Per was referring to.  So if you have a list of Integers as
 choices, set the propertymodel to an integer.  If you instead have a more
 complex Object (say MyChoiceObject) for your choices you use that.  To
 render the choices, Wicket by default will just do ToString on the Object
 inthe choices list, unless you create an IChoiceRenderer.  In any event,
 you need to set the PropertyModel's object to an object that is int he
 List of choices to preselect one of the objects.  The example below is a
 good on, you should look at the RadioChoice and DropDownChoice, since they
 both use the same idea with their propertymodels.
 
 The point is that at some time, Wicket will try to cast one of the objects
 in the list into the variable in the propertymodel, so they have to  have
 the same type.
 
 Hope this helps...

Re: create new model object of a Form from one of its FormComp values??

its simply easier to say:

bean.getdate() if you are using a bean, or just date if you are
binding to a property on the form subclass vs
(Date)textbox.getModelObject(); which requires you to keep a reference
to the textbox component anyways.

 Instead of a massive copy action e.g. in your onSubmit, you can

 I do understand advantages of using bean with CompoundPropertyModel, my
 question was related to the situation when you are forced to create your
 target object after the form is submitted. For instance, when you create
 different kinds of objects based on what exactly was submitted, or when
 constructor of the target object takes certain values and there're no
 setters for those values. Or, like in my situation, when both of those
 restrictions apply.

 Of course, maybe I'm missing something, and there's also a way to use this
 approach even in cases described above.

Getting familiar with Swing will almost certainly help you get Wicket.
Just keep in mind that with Swing, you would update values by
'pushing' them (for which you'd typically make heave use of the
observer pattern, e.g. using PropertyChangeListeners etc), whereas
with Wicket you would rely on the request cycle doing it for you (we
often call that 'pull' and it is in fact an example of Inversion of
Control, since you let your model objects being updated by the

Re: Override HTML in html fragment

 We want to switch an input field between input type=text and textarea
 depending on how large the existing data is. Is there any way to do this
 without needing a spurious placeholder element? ie We would rather not have
 a  but rather just get the text or textarea in the final HTML .

You could create a custom form component that can both be a text area
or a text field.

 So anything I can do in onComponentTag etc to change the tag name in the
 HTML file?

Yep. From the top of my head, you can do this with tag#setName

This sounds like very similar question to
http://www.nabble.com/Link-to-last-version-of-a-page-of-a-given-type-class.-td14994042.html

Its like a page is designed to maintain state only while you operate
components within it.  Clicking on a link to the page instantiates a new
one! (even tho old ones are kicking around in the page store or session)

Sure the FAQ example could be static, but it may well have some state
associated with it.

Anyway, I've got a limited workaround.

It seems like a commonly used concept.

Re: parse directive in velocity template failing

2008-01-21 Thread James McLaughlin
fattymelt,
It used to work that you could jar up your templates and put them
under WEB-INF/lib. If that doesn't work, create your own
velocity.properties file and define the init-params
velocityPropertiesFolder and velocity.properties in your web.xml. You
can define there which loaders to use and what root the
FileResourceLoader should use. Best of luck, fattymelt!

Re: bookmarkable link keep recreate the objects.

2008-01-21 Thread dvd
Thanks. I looked that source of the staticpages examples and even more troubled 
with it. It generates each static links via a costly 
markup object creation and attribute modification.
In a base template page that may contain,say 50 such links, 
that would be displayed for all site (bookmarkable) pages, 
it would mean  a lot of object creation/destruction just for a static markup. I 
saw a post about running out of wicket memory during stress test. I had quite a 
few times noticing the turnaround is quite slow in my app even though it is 
just a page with many constructed links, even though I do not have test suite 
to back it up. 

Would it be possible to turn a bookmarkale/stateless page object
into a stateful page during a session once user first access it.
After all, bookmarkable page link is for accessing the page when you
return to it after ,say  a few days. Once you access/create it,
during the session, it should be considered a stateful.



  This is obviouly a huge performance issue.

I wonder if it is. Java is optimized for creating objects, and
creating new ones is often cheaper than reusing old ones if you take
synchronization and lookups into account.

Are you sure it is a bottleneck? If you haven't seen any actual
performance problems (and determined that it is the web tier causing
it, which is often unlikely given that accessing the back-end such as
databases often take the majority of the processing of a request)
you'd be wasting your time. Premature optimization is evil :-)

If you're still unconvinced, take a look at
org.apache.wicket.examples.staticpages in wicket-examples; it might do
what you want.

Well, that's an excellent reason. I'm not crazy about Groovy myself

when it was still in alpha. Since then it got much better I hear. And
there are plenty of people who seem to like Grails.

yes and it is, however, it is up to you to determine the scope that

for conversation scopes you pass the reference around into pages that
define the conversation

for session scope you should store that reference within session.

wicket is doing exactly what you told it to do

you call final Object record = listItem.getModelObject(); 1000 times

which in turns calls listviewmodel.getobject().get(index); where index
varies from 1 to 1000

listviewmodel is PropertyModel(this, records) so when its
getobject() is called (1000 times) it calls getrecords() method

thus your getrecords is called 1000 times - just like you have it setup.

you should read up on detachable models and loadable models - models
that cache a value for the duration of a request.

for example, if you replace new PropertyModel(this, records) with
new LoadableDetachableModel() { Object load() { return getRecords();
}}

getRecords() would only be called once per request.

also if you have read the javadoc of ListView you would have noticed
that it does not recommend using ListView with database driven data.
ListView is made to work with lists. in a list an item is identified
by its index, in a database rowset an item is identified by its
primary key.

you took an example that uses static data where getrecords() is a
cheap call and expect it to work with database data without
modifications - where getrecords() is an expensive call, dont you
think that is silly?

if you want to display database data i would look into DataView and

  But I just noticed the following perhaps you can point out
  surprising (to me) issue right away.
  It is a simple list view display with
 
  class Test{
  PageableListView listView = new PageableListView(records, new
 PropertyModel(this, records),
  rowsPerPage) {
  public void populateItem(final ListItem listItem) {
  final Object record = listItem.getModelObject();
 
 public List getRecords(){
 return a record list from db query
  }
 
  }
 
  what I noticed that for each populateItem call, it would invokes
  getRecords() (perhaps with further indexing). So it I have 1000 records
  in db, it would issue 1000 query for the same result list.
  What I am doing wrong here? I basically took an example class from wicket
 website and replace the fixed record list with a db query and
  could not explain the extreem slowness until I found out this problem.
 
 
 
  you are free to write your own coding strategy that checks for
  existence of these pages in session before creating a new instance.

   these pages are not created until accessed...so not sure what you mean
  
I meant once they are created, accessing it again (say hit refresh
 button
  on browser) should
   not result in a new page object recreation, instead using a way to
   locate the previous created object and rerender it as in a stateful
   page.

Re: parse directive in velocity template failing

2008-01-21 Thread fattymelt

Just to be sure...

In the Wicket section of web.xml I am going to add the two init-params. One
of which defines the folder in which to find my properties file, and the
other is the actual filename. Then I can use that properties file to specify
what my TEMPLATE_ROOT is.

The only I don't get, is that I have working templates now that are in
WEB-IN/templates. So, it isn't like velocity-contrib isn't finding them. So
I'm not sure why the parse directive isn't looking there, too?

 fattymelt,
 It used to work that you could jar up your templates and put them
 under WEB-INF/lib. If that doesn't work, create your own
 velocity.properties file and define the init-params
 velocityPropertiesFolder and velocity.properties in your web.xml. You
 can define there which loaders to use and what root the
 FileResourceLoader should use. Best of luck, fattymelt!

  Eelco,
 
  I will take a look at it, but I'm not big on Groovy or Grails.   I decided
  to write the Wails framework as an exercise in learning Wicket and if it
  turned out to be something folks might like, then they could feel free to do
  so.  I was somewhat active in the Tapestry (4.x versions) community for a
  while and Wicket has interested me for quite some time.

I'm in the same spot, looking to learn more wicket (groovy - not so
much). It would be fun to try to collect some editors (and in my case
read-only displays) for specific classes. I guess that it would be a
good idea to try to narrow that scope a bit. What I am after is in the
end two applications, one delivery-side which is the site with
published content. The other is the administrative site where you
publish content. So far nothing special apart from that the look and
feel should be consistent for display and editor components.

I would like to have a registry of editors and display-components. The
framework selects which editor or display to use based on the type of
content. I guess this is where you actually get some benefit from such
a framework. The dynamic selection of components based on type
information. For my case it is enough to register editors with a key
based on a java class at application start up. I guess that James
might have another tack on how this should work (I haven't looked at
Trails that much). Also, I would be perfectly happy to have a
specific java class hierarchy representing the domain (perhaps rooted
in some interface like 'Content' and ' PersistentContent'. I guess
this is a bit different scope from Wails and stuff like Wicket Web
Beans (http://wicketwebbeans.sourceforge.net/)

So, to narrow the scope, I'm interested in creating a Component that
looks at some (request) parameter to decide which content to look up
in a backing store. It would select an appropriate editor or display
based on the type of content. The editors should have a (somewhat)
consistent Look and Feel.

Judging from this mailing list there seems to be other people working
on CMS-like frameworks. Perhaps others (apart from me and Mr. Carman)
might be interested in something like this also?

Cheers,
Johan
