Hi Igor,
does this mean that you wrote a Border component that handles multiple
formcomponents at once? Or that you wrote a Border component that
handles only one formcomponent at a time (like the
FormComponentFeedbackBorder)?
The first is what I've been trying to figure out, because I find the
second way of doing it very code-intensive in both Markup and Java code.
I could use some example code if that's possible, since I haven't been
able to figure out how to do it.
I can visit all formComponents (getForm().visitFormComponents()) but
adding new components to them during rendering is not possible if I'm
not mistaken?
Regards,
Onno
yep, i have a border implementation that does just this.
it searches its hierarchy for a formcomponent(s) and adds labels, then if
there are any errors it renders them after the component. so it is
definetely possible, you still have to add a border/component but the
chances are you are adding a label/component anyways.

Hi,
I'm new to Wicket. I worked with Tapestry before and I was wondering if
there's something like the Tapestry ValidationDelegate available in
Wicket?
By adding a ValidationDelegate to a form I was able to override methods
like writeLabelPrefix, writeLabelSuffix, writePrefix and writeSuffix.
That made it very easy to add a '*' behind each component in the form if
it was required and when it was in error I could automatically render
the error-message behind the component and apply an error-style to the
label of that component.
It made life much easier and saved a lot of code.
So far the only way I've been able to get error-messages to render
behind component in Wicket is by using a custom component that I
manually have to add after each component to both the template and to
the Java code. I haven't yet found a way to add behaviors to components
or forms that can render this kind of markup behind an existing
component or its label.
Rendering error-messages behind components is quite common and I'm a
Wicket newbie, so I'm sure I must have overlooked something. Any help
would be appreciated.
regards,
Onno
