Good to know. Does it make sense to update the 2.1.x? I could do it, if

No, it was decided not to upgrade in branch because of the incompatibilities. A
patch level release wouldn't justify such a change.
Ok, thanks for that info. That means that I will have to stick with the
"new Function" solution for lenya, because we are using 2.1.x there.
I will try in forrest where we use trunk. ;-)
not necessarily, you can only change the rhino lib as it is *mostly* backwards
compatible.
If this is okay (checkout the status.xml in trunk to find the differences) for
Lenya, just do it there. We only can't ship a 2.1.x release of Cocoon with an
incompatible Rhino library.

yes, it is. trunk uses the latest Rhino from Mozilla (1.6) and branch uses and a
forked version of Rhino 1.5.

Yeah, Antonio is right.
The eval() gives "Calling eval() with anything other than a primitive
string value will simply return the value. Is this what you intended?".
...and that is not what I was intended. ;-)
Hmm, you're right, I just tried it myself and got the same thing. eval()
must be broken in Rhino.
Another possibility: use the "new Function(string)" constructor to
create a function from a string and then call it, for example:
var evalFunc = new Function("string of JS code to evaluate here");
evalFunc();
just for the records: which Cocoon version are you guys using?
Please note, that the Rhino version in trunk is *mostly* compatible with Rhino
version in 2.1 branch.
There are only some some minor issues - see status.xml in trunk to find out the
details.
You should be able to simply replace rhino.jar in branch with the jar from
trunk.

If you want to pass particular arguments to it you can do that too; more

Cheers that solved the Object[] problem but still I cannot do what is
described in the background. :( It is the same like with execScript. I
think that the context is not right.

I had to build an object in flowscript to get handed off to a form binding (MultiValueJXPathBinding only knows how to bind to a Java Array :-(...). I did it by building up an ArrayList and then invoking its toArray(). So there's another way to skin the same cat. —ml—
