JSF rendered multiple combined conditions

Question

I need to give condition like

 if((a == 12 and b == 13) or(a == 12 and b == 15)) 

in JSF rendered attribute.

Can anyone help?

Answer 1

Assuming that "a" and "b" are bean properties

rendered="#{bean.a==12 and (bean.b==13 or bean.b==15)}" 

You may look at JSF EL operators
