Form not displaying messages correctly

[Taro Fukunaga]

I have a FencedFeedbackPanel inside a form but when I try to display a
message, the form closes and the message is displayed on the main page
instead of in my form. The form is in turn inside a modal window (see
hierarchy below). When I have invalid input, I want my form (and modal
window) to stay open and the error message displayed on that form so that
the user can correct it. 

public class MyForm extends Form {
  public MyForm {
FencedFeedbackPanel feedbackPanel = new FencedFeedbackPanel(
"myFeedbackPanel", this );
feedbackPanel.setOutputMarkupId( true );
add( feedbackPanel );
...
  }
}

I am also using a FormValidator and am adding it to my field for validation.

public class MyForm extends Form {
  public MyForm {
   ...
   final TextField myInput = new TextField( "myInput", new
IModel() {
   add( new MyFormValidator( myInput ) );

The code for MyFormValidator is similar to
http://blog.armstrongconsulting.com/?p=40, except that I'm using a 
TextField instead of a TextArea. Like the example, in my code I am
just saying error() in the validator and am expecting it to display inside
the form.

The Hierarchy is like this:

MyPage
  |
MyModalWindow
  |
MyPanel
  |
MyForm
  |
Input Field

I'm using Wicket 6.5

Thank you.

Re: Submit button without form component

Hi,

I haven't tried something like this before and I don't know what exactly
breaks but the simplest solution I see at the moment is to use
StatelessForm.

Submit button without form component

[Bertrand Guay-Paquet]

Hello,

I have action links which I want to transform to POST actions since they 
can have side-effects on the database. (See 
http://stackoverflow.com/questions/679013/get-vs-post-best-practices) My 
understanding is that this is only possible with either javascript or forms.


I decided (for now) to use forms since they're more accessible and 
easier to do while keeping the page stateless. I was hoping to use 
markup like so:


do it!


Note that there is only a Button component and no Form. Since the form 
contains only the button, I'd really like to omit it from the component 
hierarchy to keep things simple. Is this possible? I can't get my 
Buttons onSubmit() method called... One part of the problem is that the 
"action" attribute gets changed automatically by Wicket to a relative 
path to the application context root.


Or is there another better way to achieve POSTing in Wicket?

Regards,
Bertrand

Re: Example for saving value edited in Text Box on exit event

[Martin Grigorov]

Hi Bruno,

What is the current problem ?
I think your code should work.
But you may either change the event to 'change', 'blur' or 'input' or at
least add throttling (I don't remember the syntax for 1.4) because now it
will fire Ajax event for every typed character.

Ah, and Wicket 1.4/1.5 work with inline attributes so you need the 'on'
prefix -> onkeyup.
