Re: [rules-users] For loop inside a modify block problem

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. -W On 11/01/2012, Martin A <wmlsub(a)gmail.com&gt; wrote: > Hi, Davide, > > Here is how my rule looks like : > > when > $item : Item(param1 != 0, param2 == 0, !(this instanceof SpecialItem)) > $gsc : SomeBusinessLogic > then > $gsc.doSomething($item.id); > for (int i = 0; i < $item.quantity; i++) { > $gsc.doSomethingElse($item.id); > } > update($gsc); > end > > The above snippet throws an error @ i < $item.quantity, and says 'no such > identifier $item'... > I can't figure out what might be causing this. > > Thanks > > On Tue, Jan 10, 2012 at 10:08 PM, Davide Sottara <dsotty(a)gmail.com&gt; wrote: > >> Did you remember to bind $item to some expression in the LHS ?
