Subject How to style a single tr:inputText with a background-color depending on a state?
Date Thu, 31 Aug 2006 15:49:14 GMT
I want to style required input fields (tr:inputText) with a different background color and
only the <input> element should be affected.
With ADF Faces I used a little trick (see below).
Now I want to use Trinidad and the trick doesn't work anymore!
I have found no way to style a single component instance with a style class.
(Don't want to write an inline style for every required form field).
The documentation says about attribute styleClass: 
"If in ADF, styleClass and inlineStyle were rendered on the label and the <input>. In
Trinidad, these attributes are rendered on the root dom element."
Sorry, have no clue what that means. Does it mean the root of the document or the parent of
the <input> element which is a <td>? 
In the end it make no difference if I use attribute styleClass or not. :-(
Any hints are welcome!

Hi Dan,

Are you looking for a solution like this:

            <af:inputText value="#{bindings.Title.inputValue}"
                          styleClass="#{bindings.Title.mandatory ? 'required' : 'nonrequired'}"

The EL expression in the attribute styleClass makes the trick. The EL expression resolves
to styleClass="required" when the Title is mandatory (example uses Oracle ADF which provides
for a property like 'Title' some metadata like 'mandatory' or 'updatable').

The styleclass must be defined in a CSS or your Skin-CSS:

input.required, textarea.required, select.required {
  background-color: rgb(255,255,181);
  border-style: solid ;
input.nonrequired, textarea.nonrequired, select.nonrequired {
  background-color: white;
  border-style: solid ;

>From my point of view everything you need is available to solve your styling needs. ;-)
