Hi Ken,
For info on myfaces/tomahawk tags go here:
http://myfaces.apache.org/javadoc.html
Using the TLD(Tomahawk) link, you can info on the t:inputText component,
which does have this attribute.
The attribute isn't on the standard h:inputText component, ie it's a
tomahawk extension, available only if you use the t:inputText component
instead of h:inputText (and include tomahawk in your classpath).
I don't know whether the behaviour you see with the normal one
(required=true causes error for components when readonly=true) also
applies to Sun's JSF implementation but I wouldn't be at all surprised.
Web browsers don't send data back unless the field is editable, and if
the JSF implementation (of any brand) doesn't see data for a required
field then it has to complain.
Maybe a JSF impl could work around this by putting the values of
readonly fields into hidden input fields instead so they *are* present
on postback but AFAIK MyFaces doesn't do that (and I'm not sure whether
there are other problems that would be caused by that).
It seems to me that your options are:
(a) Remove the "required=true" attribute from the input field and
instead implement the check in your action methods.
(b) use t:inputText and disabledOnClientSide=true
Regards,
Simon

I am looking at this documentation,
http://java.sun.com/javaee/javaserverfaces/1.1_01/docs/renderkitdocs/HTML_BASIC/javax.faces.Inputjavax.faces.Text.html
I don't see it has the '"disabledOnClientSide" attribute.
Thanks.

Thanks. Is this '"disabledOnClientSide" a JSF standard attribute (JSF
1.0? 1.1?) ?
or it is a myfaces extension?
I can't find any documentation about that.
Thanks for any help.
