Re: Validation and component feedback for editable column component
in table/list
Seems like you might be missing the part where you have to add a
feedback panel to display the error messages in a form. Since you
mention that your previous application showed the message near the
field, this page might help you:

RE: Validation component feedback in table column
Posted by Kenneth NA <ri...@live.se>.
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?

RE: Validation component feedback in table column
Posted by Russell Simpkins <ru...@hotmail.com>.
Use the ComponentFeedbackPanel,
ccFeedback = new ComponentFeedbackPanel("ccNumberError",ccNumber);
ccFeedback.setOutputMarkupId(true);
addOrReplace(ccFeedback);then you can do this:
<input wicket:id="ccNumber" value="" class="" type="text" />
<span wicket:id="ccNumberError"></span>

I have been experimenting with this for while more, but I can't seem to get it to work as I want.
I have attached a small quickstart.
I have a table with an input field on each row, where I want to validate that the entered input value should not be allowed to be more than the displayed value, in that case, a message should be displayed next to the field, in the table.
I have added an onblur event to the input field and also a validator.
If I enter a value above the limit and tab out of the field, the validation message is displayed next to the field. If I instead enter a errornous value an click the submit button, the error message(s) is displayed in the form feeback and not next to the field. How do I get the validation error to be displayed next to the field?
I have been reading alot of examples, javadoc and source now and can't get it to work the wy I want.
I wonder how I change my code to get it to work?
