Connecting output of Loop Value block to Join Input

edited November 2018 in Help
I am trying connect the output from the loop values block to a Join but I face the following error:

Some input of type com.rapidminer.example.ExampleSet in not provided.

I think the error occurs because I am trying to connect IOObject output to the Join Input. I have tried using the Append and Flatten Collection blocks but to no avail.


Any ideas on solving this issue .

Help is greatly appreciated
Thanks

    Hi,

    i think there is a append missing after Loop Values (2).

    Hi Martin,

    I tried using an Append after loop Values (2) but I am still facing the same issue. The XML code is given below after using Append:

    Martin - when I put this XML into RM 7.0, I do NOT get a process.  Do you?

    Hi,

    not Martin, but answering anyway: Works for me. What does your log say when you do it?

    Regards,
    Marco

    I just paste the XML and then I see nothing in the process window.  From what I can tell, RM 7.0 tries to validate the process and then deletes it.  If I validate the process manually, the same result happens.  Does RM 7.0 not accept XML from prior versions?

    Hi,

    I have been using our development version so far and also just switched to the 7.0 release version. In both I can paste the process no problem. Does the "Log" panel show something when you paste your process?

    Regards,
    Marco
