Re: triggering post of a form, from client side
thanks for your quick replay . so the situation as it is now is :
i have managed to call the forms submit by the following java script :
StringBuffer config = new StringBuffer();
int i = ns.getAutoRefreshSecsConversation();
config.append(script language=\JavaScript\);
config.append(function onLoad() { getValue(); + ( i0 ?
:setTimeout(\onRefresh();\,+i*1000+); )+ });
config.append(function onRefresh(){);
config.append(document.getElementById('hiddenVar').value =
document.getElementById('textString').value;);
config.append(var button = document.getElementById(' +
submit.getMarkupId() + '); +
window.location = button.click(); } );
config.append(function getValue() {);
config.append(document.getElementById('textString').value =
document.getElementById('hiddenVar').value; });
config.append(/script);
add(new StringHeaderContributor(config.toString()));
BUT... the result i get it the fire fox is this :
i get the data posted to the server side correctly BUT im as well redirected
to the link-
http://localhost:6789/neustar/undefined
and i get HTTP Status 404 - /neustar/undefined
what do i do now how ? why does that happen instead of the normal behavior
of submit button like clicking it in the browser?!

hi,
I need to trigger the post of a form - from the client side with java
script
, but all the solutions that i have found don't work with wicket.
i have tried document.forms['commentForm'].submit(); in script -
doesn't work.
(when commentForm is the name of the form that is generated in the mark
up
of the wicket ).
i all sow tried to trigger the submit button that is in the form but
.click() doesn't work,
i have managed only to trigger Links with window.location = link.href;
any ideas ?

Re: [discuss] Organizing Wicket Stuff / Regular Release Schedule?
Great work! Its really looking good! Two more suggestions: 1. Add the maven-jetty-plugin the the root pom. It would be nice if 'mvn jetty:run' works for all the examples. 2. Remove all eclipse projects (.project .classpath) from svn and add the 'maven-eclipse-plugin' to the root project.

I agree with both of those. I'm not real sure either regarding the etiquette - that's been my dilemna throughout. That's the reason I started so many vote threads. I think both of those things would be acceptable, though. A common build setup was the goal of this.

Re: [discuss] Organizing Wicket Stuff / Regular Release Schedule?
Check: http://wicketstuff.org/jira/browse/WSYUI-6 (YUI seemed like the best option... no 'core' project exists) This also adds a logging implementation so the tinymce-examples runs with jetty:run I don't have commit access on wicketstuff, so I can't directly apply the patch :) As for svn:ignore on the .classpath and .project... I think you need to first go through and delete the files, then add them to the ignore list. thanks! ryan On Nov 30, 2008, at 11:54 AM, Jeremy Thomerson wrote: I agree with both of those.

YUI uploader?
Anyone tried using wicket with the YUI uploader? http://developer.yahoo.com/yui/uploader/ http://developer.yahoo.com/yui/examples/uploader/uploader-advanced-queue_clean.html This uses a flash object to select files and post them -- all the progress is handled on the client side rather then passing ajax info back from the server. The one bit that is non-obvious on how to integrate the script is that the javascript takes an upload url as its parameter: uploader.uploadAll(http://www.yswfblog.com/upload/upload_simple.php;, POST, null, Filedata); http://developer.yahoo.com/yui/docs/YAHOO.widget.Uploader.html If you select multiple files, this could be called multiple times -- you can also upload multiple files simultaneously. Any thoughts on how to handle this in wicket? The only solutions I can think of are not very wickety (add a servlet and then put stuff directly in the Session) Thanks for any pointers! ryan

Problem with detaching elements
Hello,
I'm writing an web application using Spring, Wicket and Hibernate. It's the
first time I use this technologies, so forgive me if my question is trivial.
In my application i have a many to one relationship between Hotel and Room.
On admin panel I'd like to have possibility to edit Hotel data - including
modifying data of rooms that belong to this hotel. Unfortunately, when i try
to save modified hotel, only it's data are changed - rooms stay they were
before modification. And when i try to delete a room, i get an exception
that says i try to delete detached entity
(java.lang.IllegalArgumentException: Removing a detached instance
pl.molejnik.hotbookings.model.Room#1).
I've spent whole day looking for solutions for this, but I failed... I'd be
very grateful if anyone could tell me what i am doing wrong.

Re: Problem with detaching elements
Hello,
thanks for link to the article - it was very interesting. However, I still
don't see clear connection between this case and my problem - I use my own
DomainObjectModel which extends LoadableDetachableModel (and after reading
once more the section about them i still can't see any mistakes in mine
usage of them - maybe i need some sleep after all).
I think i noticed where the problem lies, but still I don't have any clue
how to fix it. The hotel's data including rooms list are loaded correctly
and rendered on the first time. But when i submit the form, only hotel's
direct data (name, address, etc.) are updated. I discovered, that the list
of rooms i use as a model for my PageableListView is probably detached
immidiately after render and the changes made on her aren't propagated to
hotel when i persist it. Still, as I said before, I don't know why it
happens and I'd be very grateful for some more explicite answer.
Thanks in advance.
Best regards,
Michał Olejnik
PS. If you need some more code to help me let me know and i'll paste it

GridView and PagingNavigator - issue in page navigation
Hi,
I am using GridView and PagingNavigator to render a series of podcast elements
in my database.
I am using wickets 1.3.5 with Hibernate and Tomcat.
The first page renders fine but in trying to navigate using the Paging
Navigator - It looks like the state is lost and I get the following error

Re: Problem with detaching elements
final Room r = (Room) m.getObject();
item.add(new TextField(costPerNight,
new PropertyModel(r,
costPerNight)));
there you are binding your model directly to the object thus keeping a
reference, instead
new propertymodel(m, costPerNight);

DomainObjectModel which extends LoadableDetachableModel (and after reading
once more the section about them i still can't see any mistakes in mine
usage of them - maybe i need some sleep after all).
I think i noticed where the problem lies, but still I don't have any clue
how to fix it. The hotel's data including rooms list are loaded correctly
and rendered on the first time. But when i submit the form, only hotel's
direct data (name, address, etc.) are updated. I discovered, that the list
of rooms i use as a model for my PageableListView is probably detached
immidiately after render and the changes made on her aren't propagated to
hotel when i persist it. Still, as I said before, I don't know why it
happens and I'd be very grateful for some more explicite answer.
Thanks in advance.
Best regards,

Well, that of course worked - as I wrote earlier I'm very grateful.
Thank you very much for your help once again.

there you are binding your model directly to the object thus keeping a
reference, instead
new propertymodel(m, costPerNight);

Re: Bug of Wicket when iterate the form using iterator()?
MarkupContainer's children field is declared as an Object and can refer to
a ChildList - which is a List, hopefully (until it's genericised) of
Components,
an Object[] - again, hopefully of Components,
a Component - ie a single child, or, even
a ComponentSourceEntry - a bare-bones representation of only the
essentials of a Component from which it can be reconstructed.
I assume MarkupContainer's implementation was refactored (_from_ something
much more straight-forward) as an optimisation, in particular related to
serialisation, with the argument probably along the lines of: it is common
for a MarkupContainer to have just a single child, so we don't want the
luggage of a List in those cases etc ...
All this can make MarkupContainer pretty fragile, easy to accidentally
break. If the optimisation argument is really strong enough (I expect it
must have been at the time and may still be), at the very least, all the
messy operations on children could be encapsulated in a class (perhaps
called FunkyChildren, possibly as an inner class if it necessarily needs
access to its owning MarkupContainer instance's guts and is never used
outside this context) that exposes only friendly methods like
set(int index,Component child) and
remove(Component child)
etc ...
Apart from simplifying MarkupContainer, the above design would also have the
benefit of making it possible to address the problem in hand (with the
illegal runtime array cast), mend what's broken and test this funky,
edge-case(?) behaviour without having to interfere with MarkupContainer.
And, if there's a simpler/better/more efficient FunkyChildren possible for
1.5 just plug in the new implementation. Importantly, as this an internal
change (internal to MarkupContainer), there will be no API break (neither
within Wicket nor in the public API).

No, I think it's a limitation of Java. You cannnot cast
arrays.

Re: Bug of Wicket when iterate the form using iterator()?
The only problem right now is the cast to Component[]. The fix is
easy, just change it to Object[]. The optimization makes a lot of
sense and there is reason why it can't really be simple.

inmethod-grid generics?
Hi- Is there any interest in making inmethod grid generic? I have a half-way implementation that makes IDataSourceT -- it does not make IQueryResult generic though. Is there anywhere to attach patches for inmethod-grid? I don't see anything on: http://wicketstuff.org/jira/secure/Dashboard.jspa thanks! ryan
