App objects present in Studio, absent in Server

SGolbert

Hi RapidMiners,

 

I am facing a strange problem where I have a master table with ids and a bunch of subtables that I filter according to these ids. I publish objects both for the master and the subtables.

 

In Studio:

 

However, when creating a visualization in the app, only the master table is present!

 

I attach the process:

 

<?xml version="1.0" encoding="UTF-8"?><process version="8.1.003">

    <input/>
    <output/>
    <macros/>

    </process>
  </operator>
</process>

If you know a solution I will appreciate it.

I think I've found the issue. It has to do with the App objects being generated in a Loop Values operator with the parallel execution turned on. The work around is to disable parallel execution. I think this is part of an open support case, so hopefully this problem won't happen again in future versions.
