Extending the default renders of input components
Hello,
I want to render input components with a red background if validation
failed.
To enable this behaviour for all components I thought of writing a decorator
for the renderers,
which appends a specific css-class to the fields if the validation failed.
How do I tell jsf to decorate the renderers?
With kind regards
Florian Reiser

Hi Florian,
although this is an older thread... Your solution seems to be interesting
but we're wondering whether it's only technically feasible in JSF 1.2?
(we're still on Trinidad 1.0.x)
If not, it would be very nice of you, if you could share some more details!
Thanks in advance,
Carsten

Thanks for all your suggestions.
In the mean time I have solved my issue with a custom validation phase
listener.
After the validation it appends an error style class to the styleClass
attribute of the components with messages.
With kind regards

Re: Extending the default renders of input components
Posted by Matt Cooper <ma...@gmail.com>.
I think using a custom skin would be more robust. I wonder if
defining a skin extension with the following definition would be
sufficient:
af|inputText:error::content {
background-color: red;
}
This definition means that the the background-color applies to the
internal psuedo-element named "content" of the the inputText component
when the inputText is in an "error" state.
(I have not tested this myself.)

Matt

Hi,
in the past I wrote a blog entry about how to extend the Trinidad renderers.
Perhaps that helps you as well (see [1]).

RE: Extending the default renders of input components
Posted by F....@delagelanden.com.
Hi,
I recently started using a custom OutputLabelRenderer which is a
subclass of the Trinidad's default renderer.
I don't know if you can decorate an existing renderer.
To replace the default OutputLabelRenderer I put the following fragment
in faces-config.xml
<render-kit>
<render-kit-id>org.apache.myfaces.trinidadinternal.core</render-kit-id>
<!-- render-kit-class></render-kit-class -->
<renderer>
<component-family>org.apache.myfaces.trinidad.Output</component-family>
<renderer-type>org.apache.myfaces.trinidad.Label</renderer-type>
<renderer-class>com.mycompany.jsf.renderkit.core.xhtml.OutputLabelRender
er</renderer-class>
</renderer>
</render-kit>
I did have some trouble finding out which renderkit id to use. If you
don;t use the correct id the default may still be used instead of your
own.
Hope this helps.
Good luck,
Freek Segers
