How to Set icon/image programatically in ADF before page loads

Question

This is my UI:
Depends on the condition i want to set icon/image programatically in my java code.Before page load im calling this method.
So i couldnt take binding value also,it throws null pointer exception.Then i tried setting icon/image programatically.
<af:commandImageLink text="settings" icon="#{bean.iconsettings}" binding="#{bean.bind}"> </af:commandImageLink>
My bean:
private RichIcon iconsettings;(its getters and setters)
private void method(){                         // method
if(cond){
this.iconsettings="/images/20.jpg";   //trying to set icon in a string.but it throws me error that cannot set RichIcon to string.
else
this.iconsettings="/images/19.jpg";
Could any one tell me how can i set icon/image in java code.Before page loads im performing all above said tasks.Please help.

Answer 1

Well, you set the icon property to a bean method, which you have done. The bean method however need to have the signature
public String getIconsetting()
// your code returning hte path to the icon
if(cond){
     return ="/images/20.jpg";   //trying to set icon in a string.but it throws me error that cannot set RichIcon to string.
else {
     return ="/images/19.jpg";
The bindproperty is not needed, remove it and remove the RichIcon Iconsettings too´as it's not needed to and is the wrong type anyway.
