Short circuit operator for JSF(P) EL

Are there short circuit operators for Expression Language used in JSF, JSP?

I mean &&,|| Java analog,when if it's obvious that further evaluation of boolean has no sense, that evaluation is stopped.

I observed usage of and, or operators and looks like they're not short circuit.

Solution

  • It are definitely short circuit operators. 

    #{bean.left or bean.right}

    The right hand won't be evaluated when the left hand evaluates true.

    #{bean.left and bean.right}

    The right hand won't be evaluated when the left hand evaluates false.
