jsf - 如何更改 tr:message 样式

Answer 1

put this in your trinidad-skinning.css file:

.AFComponentMessageCell
{
    background-color: red;
    color:blue;
}

the tr:message tag is for messages, you put into FacesContext like this

FacesContext facesContext = FacesContext.getCurrentInstance();
FacesMessage msg = new FacesMessage();
facesContext.addMessage( "id_of_component", msg );
