Re: DropDownChoice and Raw Input values (of e.g., textfields)

[Martin Makundi]

AjaxFormValidatingBehavior extends AjaxFormSubmitBehavior. I do not
need the feedback update, so I tried AjaxFormSubmitBehavior.

The problem is that AjaxFormSubmitBehavior actually submits the form
(executes my form.onSubmit which actually tries to save the form when
still incomplete!!).

I can work around this by analyzing which button submitted the form
(and if null -> do not save):
myform = new Form(..) {
  protected void onSubmit() {
super.onSubmit();
if (findSubmittingButton() != null) {
   // do actual save here
}
  }
}

It seems like a hack :) Should I just roll with this solution?

Re: Setting HiddenField name attrribute value

[Ritz123]

Matthijs,

Those are good suggestions. I would have gone server side myself. There is a
trade off user experience vs. more robust and it just so happened this time
we are going with better user experience hence the use of javascript. The
javascript, I want to use is very basic, thats the reason why I am not doing
AJAX as there is no need to even go to server side partially. Javascript
will be used purely on the client just to update inner html. Just to give
you an idea - this is for the e-commerce checkout where the entire checkout
can be done from 1 page only with very few clicks, it wont be possible
without the use of javascript.

I didnt find any documentation on using templates for javascript - will
appreciate any pointers.

Thanks

Re: Setting HiddenField name attrribute value

[Matthijs Wensveen]

Is there any specific reason you don't want to do this server side? Not 
using javascript would make the application more accessible, and 
probable also more robust and secure. Unless you're targeting some very 
specific user group, I always try not to depend on javascrip / ajax 
(that's why I love the AjaxFallback stuff in wicket so much).


Just my 2c.
Matthijs

PS. If you must use javascript, why not use the hidden field's id, which 
can be controlled with setMarkupId. But it might be better not to use 
setMarkupId (to avoid id collisions). You could write some javascript 
(with use of templates) that fills in the markupId (getMarkupId) 
dynamically.


Ritz123 wrote:

Hi,

Is it possible to set specific name to the hidden field component?

Here is my usage scenario - 


1. I have radio group for shipping options on a page.
2. Depending on the shipping option selected, I need to show the order total
changed 
2. radio has associated model which obviously contains more information than

just the shipping price

The only way I can think of doing this efficiently without going to the
server side is by using hidden fields for shipping costs. Using the
javascript to update the total on the page. Problem is, seems like hidden
field names cannot be specified or controlled and hence cannot be referenced
by javascript precisely.

Correct me if I am wrong, also let me know if there is a better way of doing
this.

Re: MarkupResourceStream and classloading

Alternatively, may take a look at OsgiClassResolver.java

OsgiClassResolver.java is an implementation (improvement needed) 
of IClassResolver to resolve classes that are stored in osgi bundles.

My take is to implement your own version of IClassResolver.

Ok, it's done :  http://www.nabble.com/file/p18044618/issueTest.tar.gz
issueTest.tar.gz .

BTW, it's an Databinder app. Everything will be launched in memory. When you
start, you'll be invited to enter the creature's name, then you'll be
redirected on the creature page where you'll be able to click on a "+" link
to increase its hitpoints... it's the link which fails.

BTW, doing this quickstart, I've noticed that it was working a bit better
when, in the DemoApp init, I was adding manually the creature to the user
(see the TODO). However, in this case, the update I do on the model aren't
kept, so it doesn't work properly neither...

Thanks again

Betreff: DropDownChoice and Raw Input values (of e.g., textfields)

Hi!

Is there a simple way to make DropDownChoice.onChange behave in a manner 
somewhat similar to an 
AjaxFallbackButton.setDefaultFormProcessing(false).onClick?

I have a dropDown and a textField. They are both within a PANEL that gets 
AjaxRefreshed whenever the dropdown choice is changed.

The problem is, that even though I re-use the textField, it does not know its 
convertedInput (probably because the form has not actually been submitted?) and 
it resets itself to its original state. I would like it to keep its state as it 
was when the new dropdown value was selected.

Currently both textField.getConvertedInput and textField.getInput are null... 
"All I need" is to attach some defaultFormProcessing(false) behavoir to the 
dropDown (and the form submit, ofcourse) ;)

Re: DefaultAbstractTree or BaseTree?

[Matej Knopp]

DefaultAbstractTree is indeed still deprecated and will be removed in
1.5. Closest to DefaultAbstractTree in the terms of functionality
comes LinkTree, that uses LinkIconPanel as content component.
LinkIconPanel does contain node icons. Look at the LinkTree source
code, it's really short.
