Hello All,
I just wanted to thank you all for your help. I thought posting the solution
back to the list will help other people in the future.
Oki - I did the following:
I created a map for the clientId's which will hold required validation messages.
Map styleMap = new HashMap();
An additional 'getRequired" method is executed by all the components which
should get the style:
<h:inputText id="emailAddress"
value="#{ActivationForm.emailAddress}"
size="25"
required="true"
style="#{ActivationForm.required ?
ActivationForm.styleMap['emailAddress'] : ''}"
></h:inputText>
The following method finds out if there are any components with messages, adds
it to the styleMap and returns true if so.
public boolean getRequired(){
styleMap.clear();
FacesContext context = FacesContext.getCurrentInstance();
Iterator itr = context.getClientIdsWithMessages();
boolean ret_val = false;
try{
while (itr.hasNext()) {
String clientId = (String) itr.next();
UIComponent uic =
context.getCurrentInstance().getViewRoot().findComponent(clientId);
styleMap.put(uic.getId(),"background: red");
ret_val = true;
}
}catch(Exception ex){}
return ret_val;
}
That also works pretty good for components in a dataTable.
Thanks again - have a good one,
Nico

Betreff: Re: (Validation) required="true" should change my css style of
inputbox e.g. background:red
Yep, that's the simplest solution. If you don't want to emit the
style/styleClass value from a backing bean you can also use a variant such as
<h:inputText ... styleClass="#{mybean.required ? 'required' : ''}"/>
Regarding your concern about doing this in a data table, you shouldn't have any
problem provided you have the isRequired() method on each row item in your
table model.
