Re: TabbelPanel doesnt work in appengine

[Alexander Monakhov]

Hey.

I met the same problem when I started to implement my app using Wicket and
GAE. On GAE there is problem with serialization. GAE prohibits to use
replacement substitution, so WIcket's methods like Component#modelChanged()
or Component#modelChanging() cause AccessControlContext. To fix this problem
I extended TabbedPanel class and overwrote some significant methods. Here is
code for you. It works on GAE for my application more then 3 month without
any problem.

Hi Alexander

Thanks a lot for the workaround. It is working without any problems.
Hopefully wicket devs will consider making the framework more GAE enabled.

Custom Javascript Events

[Josh Kamau]

Hi all

Anyone with a sample code on how to handle custom javascript events with
wicket on the server side?

I would like to use jquery but handle events on the serverside. I had tried
wiquery but lack of documentation is really frustrating me. I have great
books on Jquery and JQuery UI and i would like to use the javascript
libraries directly but handle the events on the server side.

Please help.

Thanks in advance.

Regards.
Josh

Re: Custom Javascript Events

[Ernesto Reinaldo Barreiro]

Hi Josh,

Can you be more specific?  Which functionality are you missing and
which events you want to handle on the server side? I've been using
wiQuery for over three weeks now and I really find it intuitive and
easy to use.

Best,

Ernesto

Re: Custom Javascript Events

[Josh Kamau]

Ernesto;

On WiQuery, how do i set component configuration parameters? How do modify
the CSS?  If i find an nice jquery component elsewhere eg the tooltip or the
grid or even the jquery UI Layout, how do i integrate it?  I have a feeling
that i will have more control and have access to more jquery features if i
use Jquery directly.  I only wish i could add jquery event as behaviours the
way i do with native javascript events.

I appreciate the work done on WiQuery though.

Hi Josh,

 On WiQuery, how do i set component configuration parameters? How do modify
 the CSS?

Many components have setters and getter for their properties. E.g.

public DialogPanel(String id) {
super(id);
Dialog dialog = new Dialog(dialog);
dialog.setAutoOpen(true);
dialog.setWidth(500);
dialog.setHeight(500);
dialog.setResizeStopEvent(new JsScopeUiEvent(){

private static final long serialVersionUID = 1L;

@Override
protected void execute(JsScopeContext scopeContext) {

scopeContext.append(DialogPanel.this.layout.statement().render(true));
}
});
dialog.setModal(true);

add(dialog);
.
}

wicket:panel
div wicket:id=dialog title=Modal Dialog!
div wicket:id=layout style=width: auto; height: auto;
/div
/div
/wicket:panel

In the example above: what is stopping you from adding your own CSS
class to dialog div and on DialogPanel add a references to the CSS
file adding the custom CSS properties you want? Or even overriding
JQuery UI CSS...

If i find an nice jquery component elsewhere eg the tooltip or the
 grid or even the jquery UI Layout, how do i integrate it?  I have a feeling
 that i will have more control and have access to more jquery features if i
 use Jquery directly.  I only wish i could add jquery event as behaviours the
 way i do with native javascript events.

IMHO it is very easy to integrate third party jquery plugins as
WiQuery plugins. That's not very much different from integrating other
JS libraries as Wicket components. Do you need examples on how to
integrate new components and provide server side handling of events?
Take a look at [1]-[4]

In my opinion there is no need to duplicate the Job already done by
wiQuery developers: I think that's what you will end up doing if you
start implementing all those things on your own;-). As said: if you
have concrete examples of things you want to do and not know how to
achieve them, ask on jquery forum that for sure someone will answer
with a concrete proposal... and if it a feature the integrations
misses it will for sure make it somehow into their implementation.

Best,

Ernesto

I think they have some example/demo projects on their repo. Take a

their forum: Lionel, Julien, Cemal, Richard and others guys involved
on the project are very friendly and normally you will get your

 file adding the custom CSS properties you want? Or even overriding
 JQuery UI CSS...

 If i find an nice jquery component elsewhere eg the tooltip or the
  grid or even the jquery UI Layout, how do i integrate it?  I have a
 feeling
  that i will have more control and have access to more jquery features if
 i
  use Jquery directly.  I only wish i could add jquery event as behaviours
 the
  way i do with native javascript events.

 IMHO it is very easy to integrate third party jquery plugins as
 WiQuery plugins. That's not very much different from integrating other
 JS libraries as Wicket components. Do you need examples on how to
 integrate new components and provide server side handling of events?
 Take a look at [1]-[4]

 In my opinion there is no need to duplicate the Job already done by
 wiQuery developers: I think that's what you will end up doing if you
 start implementing all those things on your own;-). As said: if you
 have concrete examples of things you want to do and not know how to
 achieve them, ask on jquery forum that for sure someone will answer
 with a concrete proposal... and if it a feature the integrations
 misses it will for sure make it somehow into their implementation.

 Best,

 Ernesto

Re: root context, IE, home page is not found

[Erik van Oosten]

I don't get it.
I tested this fix with Tomcat and several IE versions. And . just 
worked then whereas ./ did not.

Erik.

Hi,

we also just experienced issues with this, and the fix of WICKET-2600
still causes problems (as already described in this post):

For the redirect to . tomcat produces a Location header like
http://www.example.org/. (notice the trailing dot), which causes IE to
do request exactly this url, for which no page ist mounted. Therefore
the 404 page not found.

Is there a special reason why . was chosen here?

What do you think about an alternative handling like this:

if (redirectUrl.startsWith(./)) {
   if (redirectUrl.length() == 2)) {
 WebRequest request = (WebRequest) requestCycle.getRequest();
 String contextPath = request.getHttpServletRequest().getContextPath(); // e.g. 
/myapp
 String servletPath = request.getServletPath(); // e.g. /
 redirectUrl = contextPath + servletPath;
   }
   else {
 redirectUrl.substring( 2 )
   }
}

Cheers,
Martin

Cache menu

[Wolfgang]

I'm working on a web site that has a menu bar with sub-items, and
sub-sub-items. The configuration of this menu is computed from hilariously
complex SQL queries and needs quite some time to be established. The menu
looks different for each user (session) but stays the same for the lifetime
of the session. So it's time for caching as this menu shows up on most of
the pages.

From other posts on this site I've taken that it's not a good idea to share
the components that represent the menu among different pages. Now I wonder
on which level I can cache and re-use objects.

Is it advisable to share models (in the Wicket sense), i.e. store the menu
models on the session and construct the menu components according to their
information for every page?

Or do I have to create separate, Wicket-independent data structures that
hold the menu structure information and store it on the session or in the
database?

Or am I on a complete wrong track and should look for caching of the
rendered HTML code on a component basis?

Thanks in advance for sharing your knowledge/experience.

Re: Cache menu

[Ernesto Reinaldo Barreiro]

I would opt for creating very simple Java beans containing the cached
information and store them on the session and later on use that
information to build the menu bar. If several users share the
information (e/g/ based on roles) maybe you can devise some mechanism
to store them by role so that several session share the information.
If this menu bar information does not vary over time, or you have a
good criteria to know it is stale, and if is costly to compute I would
also consider (as you suggest) storing it on a temporary database for
later use (and recompute it just if it is stale).

Best,

Ernesto

Re: Cache menu

[Igor Vaynberg]

cache whatever holds the actual data. for example in our code we have
a menu and that takes IModelMenuRoot, and using menu root object it
can render the entire menu by traversing it. store the MenuRoot in
session.

Dynamically adding rows to a html table

[Gast, Thorsten]

Hi,

we have a list of search results which are displayed in a html table. One entry 
per row. To see more details of a result, an ajax link should trigger a 
rendering of a new table row (tr) directly beneath the selected entry.
In a first approach we rendered a hidden table row (with wicket:id) which 
should be filled with the details. Currently we try to replace the table row 
e.g. with a method call to replaceWith of Component. We succeeded in displaying 
the content, but the tablerow wasn’t replaced. Instead a new one was created 
(without a markupid). So there is the problem that we have an empty and hidden 
tablerow and a new tablerow which can’t be removed dynamically afterwards.

Is there a best practice how this issue could be solved?

Regards

Thorsten

formsubmitbehaviour and textarea with tinymce behaviour

[tubin gen]

I have a form with a checkbox ,  text and a  textarea with tinymce
behaviour.
I addedAjaxFormSubmitBehavior   to the checkbox here the code


   add(new CheckBox(concur){ { add(new
AjaxFormSubmitBehavior(ResolveFindingForm.this,onChange){ @Override
protected void onSubmit(AjaxRequestTarget target) { Object
s=((FormComponent)getForm().get(adjustedAmt)).getConvertedInput();
s=((FormComponent)getForm().get(actionTakedDesc)).getConvertedInput();
System.out.println(s); } @Override protected void onError(AjaxRequestTarget
target) { } }); } });
on selecting the checkbox, in the  onSubmit methood in
AjaxFormSubmitBehavior
I get the user entered value for adjustedAmt which is a text , but the user
entered value for actionTakedDesc which is textarea with tinymce behaviour
is always null.
Please tell me why is it not updating for model with tinymce text ?
I also have ajaxsubmitbutton which works fine , but AjaxFormSubmitBehavior
is not updating value of tinymce textarea .

Re: SEVERE:Pagemap null is still locked by: Thread

hmm

looking at the stack of the of that thread that has the lock on the page map
then it seems to me that that shouldnt happen, because that thread is doing
nothing anymore if the stack dump of that thread is really the right one.

Because that just seems to be in a waiting state in a tomcat pool

So then it is more that there is some exception in front of that maybe that
somehow didnt release the pagemap

Re: Dynamic checkbox form

[Wolfgang]

Each checkbox will be associated with a model. After submitting the form (in
your onSubmit method), these models contain the value of the checkbox. As
you have a dynamic set of checkboxes you have to make you store the models
in an appropriate collection. Or, you remember the references to the
checkbox components and ask them about their model value.

Re: CheckGroup and ListView

[Jeremy Thomerson]

I haven't looked at it in detail, but you shouldn't be doing that
removeAll() and setList() stuff - it comes from a lack of using Models
properly - which is the most common mistake I see in Wicket users.  Instead,
you should give the ListView constructor an instance of some
IModelListSelectableValue.  Then simply add your new selectable value to
whatever list that model is getting it's data from.  The ListView will
auto-magically repaint everything correctly.

Re: WicketStuff version bumping?

[James Carman]

Wouldn't you release a 1.4.8 version (which goes with wicket 1.4.8)
and then go to 1.4.9-SNAPSHOT?

2010/5/5 Major Péter majorpe...@sch.bme.hu:
 Hi,

 We have 1.4.7-SNAPSHOT for quite some time now, shouldn't we release an
 1.4.8 edition and bump to 1.4.8-SNAPSHOT?

 Regards,
 Peter

Right, this would make more sense :)

RE: wicketstuff-minis status?

[nmetzger]

It works for me, but I like using the newest libraries that are out there. I 
tried copying your code to my project and using the new mootools libs, but 
couldn't run it. Probably it's my IDE again. 

In short, if you have time to update it, it would be greatly appreciated. But 
if not, it's no big deal either.

Thanks,
Natalie

Instead of templinging out html, template out xml and call it file.xls.
There is a dom for spreadsheets.

Re: convert wicket pages html to excel

[Jeremy Thomerson]

I've done this before.  I'd actually suggest not doing this.  Use jexcel [1]
- it is much more reliable and you won't have users calling you saying this
spreadsheet won't open.

I've written CSV before but then changed to Apache POI because of all 
those spreadsheet apps out there interpreting the separator character 
differently by default...
