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

[Krause, Nico]

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

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.
