RE: error(validatable)
Thanks for the information.
But if I don't have an Ajax button but a normal Button which submits the form?
There is no target "variable" in the onValidate() method.
I attached a quickstart earlier, where I showed that if I use Ajax
onblur/onchange and use onError/onUpdate there
i nor problem of showing the error but when I the later click the "submit"
button the error is NOT displayed
when they validator "kicks in".

error(validatable)
Let's rephrase my problem.
I connect a validator to a TextField in a DataView (inside populateItem() and
connect a ComponentFeedbackPanel to it.
final TextField tf = new TextField("data", new
PropertyModel(row, "data"));
final ComponentFeedbackPanel tfFeedback = new
ComponentFeedbackPanel("fb", tf);
tfFeedback.setOutputMarkupId(true);
item.add(tf);
item.add(tfFeedback);
And I also have both in the HTML markup
Is this enough for the error reported in in onValidate() for the validator
connected to the field
with error(ivalidatable); should be displayed next to the field or does it
require something more?
error(validatable, "an_error_occured");
Why I wonder is that it is not displayed next to the field, it is displayed in
the "common" feedback panel.

RE: Validation component feedback in table column
I have already added one ComponentFeedbackPanel in the populateItem() method
final ComponentFeedbackPanel tfFeedback = new
ComponentFeedbackPanel("tfFeedback", tf);
tfFeedback.setOutputMarkupId(true);
item.add(tfFeedback);
and if I also add the suggested code in the validator in method
onValidate(IValidatable validatable) when the validation fails, I get the
following error:
WicketMessage: The component(s) below failed to render. A common problem is
that you have added a component in code but forgot to reference it in the
markup (thus the component will never be rendered).
1. [MarkupContainer [Component id = tfFeedback]]
2. [MarkupContainer [Component id = feedbackul]]
3. [MarkupContainer [Component id = messages]]
4. [MarkupContainer [Component id = 0]]
5. [Component id = message]
...
So, I still wonder, have can I solve this problem?

Is it possible to register multiple behaviors for a field?
I want to register two behaviors for a textfield, is this possible, as I only
see the result and call to one of them?
This is what I am trying to do:
textfield.add(new ComponentVisualErrorBehavior("onblur", tf));
textfield.add(new AjaxFormComponentUpdatingBehavior("onblur") { ... }

Validation and component feedback for editable column component in table/list
I am a new user of wicket and I have been experimenting the last days. I am trying to migrate an existing JSP applikation to wicket. I now have a problem with feedback and validation error display. In the existing applikation, the validation errors are display next to the fields, by displaying a little error icon with the error message as a tooltip and at the same time the form component change style, i.e. testfields gets a red border. One of the pages I am experimenting with, have a list where all columns are static, like dates, numbers and amounts except one where an (intiallly empty) editable amount field is displayed. It is this field I have problem of getting to work to display errors for. The validation on each row should compare the entered amount, that it is not hígher than, one of the other amounts in the "row" model. The sum of the entered amounts in all rows are also not allowed to be higher than another amount in a form component outisde the datatable. I have attached AjaxFormComponentUpdatingBehavior with onblur which calls error(), but I just get the following warning all the time: VARNING: Component-targetted feedback message was left unrendered. I have tried adding the table in aWebMarkupContainer, I have called setOutputMarkupId(true), I have called target.addCmponent(wmc). I have also tried with FormComponentFeedbackIndicator but without success. I have been looking around the examples and a lot of web pages and now I decided that maybe someone can point me in the direction where someone have an example on just this. Even a small initial example would be appreciated. Thanks, Kenneth _ Vi vet vem du passar ihop med! Klicka här för att få veta! http://dejting.se.msn.com/channel/index.aspx?trackingid=1002952
