Hello, Wolfgang,

Looks like the same problem appears on my side... So is it a bug, or misuse of the MVEL syntax?

Best regards,
Martin

Using 5.3.0 Final.

The reported compilation problem ("no such identifier: $item") occurs
with dialect MVEL, which appears to be broken w.r.t. RHS code containing
a "for" statement. Note: the error is not flagged for the preceding occurrrence
of $item, in $item.id.

Different kind of errorscan occur, depending on how the "for"
statement is written,
for example:
int h = 10; for( int i = 0; i < h; i++) { ... } ## Error: no such
identifier: h

Avoid dialect MVEL - using Java and getters works fine.
