Connecting output of Loop Value block to Join Input

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?

Marco_Boeck

Hi,

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

Regards,
Marco

sgenzer

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
