But the script does work under Tcl 8.3.1. I need to point out that my 2nd script is NOT a "workaround". It is not a workaround because you can't convert all callback scripts into this list form; it is not the normal way of writing Tcl; and you can't change other people's code this way. It is there to demonstrate a more fundamental problem: "Java objects in Tcl should be treated as global system resources like file handles (explicit create/remove) rather than other normal Tcl objects (implicit create/duplicate/remove)." > -----Original Message----- > From: Mo DeJong [mailto:[EMAIL PROTECTED]] > > The eval command will convert its arguments to strings. > This has the effect of removing the Java object from > the reflect table right before you invoke the Java cmd. This is my point. As soon as any Java objects are converted into their string form. The Java object from the reflect table would be removed. It is not just the "eval" command. It is the whole Tcl interpreter (maybe the byte code compiler in particular). The interpreter seems to change objects into string form in various places. The fact that [list eval $x toString] works under Tcl 8.3.1, but not under Tcl 8.2.3 also demonstrate this. I was doing something even simpler: proc foo {arg} { set x $arg } I call "foo" using an "arg" that was a TclObject with a ReflectObject. The debugger shows that the execution of "set x $arg" happening inside the byte code executor. The argument is retrieved from the Tcl's procedure stack, which is just a string only representation of what I passed in. I had to write my workaround using a string<->object mapping scheme like the ones used in ReflectObject, but without the reference counting. -- Jiang Wu [EMAIL PROTECTED] ---------------------------------------------------------------- The TclJava mailing list is sponsored by Scriptics Corporation.
