> A compont can be editing mode for users to input data,  or in showing mode for display values only.  
> Attribute "displayValueOnly" will reduce JSF page size and memory size, and simplify programming.
> For example: for pickList, we have to use two components: one for editing, and one for showing:
> <rich:pickList rendered="#{bean.isEditing}"
>            value="#{bean.values}" >
>     <f:selectItems value="#{bean.selectItems}"/>  		   
> </rich:pickList>
> <h:outputText rendered="#{!bean.isEditing}"  value="#{bean.valuesAsString}" />
> After adding displayValueOnly, one component will be sufficient, very clean.
> <rich:pickList rendered="#{bean.isEditing}"
>            value="#{bean.values}"  displayValueOnly="#{!bean.isEditing}"  >
>     <f:selectItems value="#{bean.selectItems}"/>  		   
> </rich:pickList>
> This applies to all components.
