AW: Re: (Validation) required="true" should change my css style of inputbox e.g. background:red
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:
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

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
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.

Hi, have you tried it with a component binding of the inputbox in the model? Just a quick idea, but with some coding in the model it may work. regards, Gerald On 3/15/06, Krause, Nico <[EMAIL PROTECTED]> wrote: > Christan, > > Thank you, i think it's a good idea, if nothing else helps.

(Validation) required="true" should change my css style of inputbox e.g. background:red
Hello,
i was wondering how
to change the background of an inputbox by simply changing the css style to e.g.
background:red. when a required="true" - validation was set.
I was trying several
possibilties but no one seems to fit my needs and i am just right now some
kind of frustrated because of this issue.
1. Making use of the
_expression_ Language by just accessing a method/property in a backing bean. This
works fine, as long as i don't want do access Input-Elements of a dataTable. I
don't think i can use the _expression_ Lanuage to access a method with a parameter
like getStyle(componentId)
2. I was trying to
find a possibility access the components-attributes through
"findComponent("inputbox1") in the jsf-api. Unfortunatly I was not able to
find the component (my input textfield) by its name or any other
function under FacesContext. Result was allways null.
:-(
3. Implementing an
own Validator: I implemented an own Validator which worked pretty good unless
the field was at least 1 letter. The validator was not fired when i typed
nothing into the inputBox. (But this is exactly the functionality i
need)
At the end of
the day i think i have to rewrite each component and overwrite the validate
method just because of of the requirement to make the background of an input
field red if a user forgot to enter data when it's required
definitly.
Is that
correct what i am thinking? Did i ignore other facts or
specifications?
Thank you in
advance for any hint how to change the css style with in a
required="true".
Best
Regards,
Nico
