Yes. Again, this is correct. In fact, the problem is the same: in the
first example (which is the same as what you showed before), 'value' is
simply a scripting variable. It is not automatically visible to the EL;
the EL has no way to read scripting variables. Instead, it must be made a
scoped variable explicitly, as by pageContext.setAttribute().

I'm saying that scripting variables cannot be accessed at all by the EL.
Any EL-accessible values can be used as indices.
