[tcljava-user] Fwd: RE: [TDK-BETA] Error when Using TclDev Kit 4.0 debugger with Tclblend.

Anyone know why this would happen?


Patrick




Using TclDev kit 4..02 Beta debugger with TclBlend 1.4 as interpreter on
Windows XP.

Error occurs when variable is used as command.  This problem does not occur
on Komodo 4.0 or RamDebugger.

set ConnectionI [ java::call DriverManager getConnection $url ]

putsLog "transaction isolation level is [ $ConnectionI
getTransactionIsolation ]"

$ConnectionI resolves to "java0x2"

Error msg.

invalid command name "java0x2"
    while executing
"$ConnectionI getTransactionIsolation"

The JACL syntax is valid and runs correctly from the command line.  Is this
valid debugger behavior?

NB:  The error only occurs when stepping through the code using PF6.  Run
to end with PF5 is fine.  The same problem occurs with Dev Kit 3.2.

TEST
****

Put the following code snippet in a script and step through it.

package require java
set jstring [java::new String "Hello World"]
# Convert the Java string to a Tcl string
set tstring [$jstring toString]

invalid command name "java0x2"
    while executing
"$jstring toString"

You can grab TclBlend from here:    www.patrickfinnegan.com/

I don't have TDK so I can't confirm, but it appears to
me that the reflected Connection object is being
garbage collected, possibly due to going out of
scope while be run by the debugger.

Try using: 
    java::autolock 1

or wrap your connection with:
    java::lock [ set ConnectionI [ java::call DriverManager getConnection $url ]  ]

You are correct.  The garbage collection is causing the problem.  

Thanks for your help.
