Status of javaflow block in 2.2

[Bart Molenkamp]

Hi all,

Can someone tell me what the status is of the javaflow block in Cocoon
2.2? I'm trying to use it, but I'm getting an exception (I tried to run
the sample):

Caused by: org.apache.commons.javaflow.bytecode.EmptyStackException: pop
reference
        at
org.apache.commons.javaflow.bytecode.Stack.popReference(Stack.java:163)
        at
org.apache.cocoon.samples.flow.java.CalculatorFlow.getNumber(CalculatorF
low.java)
        at
org.apache.cocoon.samples.flow.java.CalculatorFlow.calculator(Calculator
Flow.java:27)
        ... 94 more

Does this sample work for others, or is the current implementation
simply broken?

Thanks,
Bart.
