Bind <rich:listShuttle> or put two list in render attribute

What do I do if I have to put two rendered condition on listshuttle.

I have a <rich:listshuttle> and I have put rendered="#{!empty Bean.arrayList}".

So if arraylist is empty this component is not rendered. However on certain occassion I want to render this component even when the arraylist is not empty.

It may be possible to bind <rich:listShuttle> with the backing bean but how can it be achieved.

Also is it possible if I put two list in the rendered field.But I think my objective still won't be achieved.

Solution

  • You should be able to put any EL expression evaluating to boolean in rendered

    rendered="#{(not empty Bean.arrayList) or (empty Bean.arrayList and Bean.conditionMet)}"
