error while working with w-AdaBoostM1 operator

Hello All,
I've installed the weka extension in rapidminer to work with the weka operators.
While I was working with a couple of operators, I've seen error "Array Index out of Bounds [0]" exception.
The same data set was working on the rapidminer & as well as some other weka operators.
I've had issues with w-LogitBoost, W-ADABoostMI, W-MultiBoostAB and some other.
While it worked well with w-DecisionStump, w-LADTree, w-ADTree

Can you anyone help me in understanding what could be the reason and what changes are required.

Thanks.

    Hello All,
    I've been working with weka operators using the weka extension.
    But when I'm trying to use the w-AdaBoostM1 operator, it is throwing an error.

    Steps followed:
    Loaded the data set
    Set the role for Label
    Connected it to the w-AdaBoostM1 operator.
    connected to the output port.

    I'm not sure what to put for the weka learning in the w-AdaBoostM1 nested process..

    Below the log for it...

    Sep 21, 2013 11:14:53 AM INFO: Process starts
    Sep 21, 2013 11:14:53 AM INFO: Loading initial data.
    Sep 21, 2013 11:14:53 AM SEVERE: Process failed: operator cannot be executed (Array index out of range: 0). Check the log messages...
    Sep 21, 2013 11:14:53 AM SEVERE: Here:          Process[1] (Process)

              subprocess 'Weka Learning'
    Sep 21, 2013 11:14:53 AM SEVERE: java.lang.ArrayIndexOutOfBoundsException: Array index out of range: 0

    Any Help?

    Thanks

    Hi,

    can you please post the contents of the rm.log file found in the user/.RapidMiner5 folder?
    Also please post the xml of a process which fails (ideally with no custom data, i.e. using the "Generate Data" operator, though it should be fine if you describe the data so we can reproduce the error).

    Regards,
    Marco

    I'm not sure if I understood your question wrong, but i'm not able to locate any user/.RapidMiner5 folder to trace the rm.log files.
    I'm working on linux environment.
    could you let me know if anything else needs to be added to generate those logs?

    Hi,

    you are using an outdated version of RapidMiner. Latest version is 5.3.013. Please update to this version, and see if the problem still exists. If that is the case, in your user home folder you should find a .RapidMiner5 folder in which the rm.log file sits. This file is only created since version 5.3.013, so you cannot find it with your RapidMiner version.

    Regards,
    Marco

    Hi,

    Thank you for the information.
    I've udpated the Rapidminer to 5.3.013 version and have run the same process.
    But the problem still remains the same.

    Could you please help me for this.
    Here is the info from the rm.log file.

    Hello,

    I am using Weka Extension and meta-learners doesn't works. The error is the same that reported by transformers123.
    Is already resolved?

    To get the process working you probably have to add another Weka Learner into the subprocess.
