[Laszlo-user] compiling to swf10 generates NullPointerException (openlaszlo 4.9)

[augusto callejas]

hi-

i'm attempting to compile a laszlo file via the browser at this address:

  /index.lzx?lzr=swf10

generates this error:

====
java.lang.NullPointerException

looking at the code:

====
        if (exitval[0].intValue() != 0) {
          System.err.println("FAIL: compiler returned " + 
exitval[0].intValue());
        }
====

looks like exitval is null or exitval[0] is null?

any help appreciated.

thanks,
augusto.
