I am using Message Broker Toolkit Version : 6.1.0.3
When I debug the message using inbuilt debugger, I am getting the error
"An internal error occurred during " "Computing hasChildren".

Please let me know the reasons for the same and what can be done to rectify it .

Thanks.

Please take a user trace, and quote the entire error message. Or look in the Windows Event Viewer and extract the entire error message from there.

I am using 6.1.09 toolkit version, on Windows XP Pro SP3.

I see the same pop-up (An internal error occurred during: "Computing hasChildren") when using the flow debugger from within the toolkit. It is then usually necessary to detach the flow debugger from the Execution group and re-launch it - which is a lengthy, frustrating process.

It is an error in the eclipse toolkit, rather than in the broker runtime. There are no errors in Event Viewer. The message can process to completion successfully, it is just that the flow debugger has "crashed".

Here is the output from the eclipse toolkit file myworkspace\.metadata\.log:

It looks rather like a bug in the toolkit. I suggest that you open a PMR - so make sure that you don't lose the toolkit log file in which you found the ArrayIndexOutOfBoundsException.
