tools fails only in workflow

Christian Hundsrucker-3
Dear all,

I developed a tool which allows an optional selection as input amongst
others. It works quite neat if I run it via "Analyse Data".
Actually, it only breaks in one condition:
If I try to run it "as a Workflow" and set the "multiple selection
input" to be set at runtime AND do not select anything at runtime it'll
raise a Cheetah error.
Even if I select nothing but prior to runtime as workflow it works fine
again.

The multiple selection is based on a data table/ loc-file.

Any ideas?

Cheers,
Christan


relevant tool specification snippet:
---------------------------------------------

[...]
     <param [...] type="select" optional="true" multiple="true"
display="checkboxes" [...]>
         <options from_data_table="fmi_[...]"/>
     </param>
[...]


Cheetah error:
