Hallo to everyone!
I am trying to assemble a workflow with two nested loops: the outer loop passes a flow variable to the libSVM node (the c parameter) and the inner loop should iterate a cross validation for one value of c at the time. If I use only the outher loop everything is doing fine. When I connect the CV loop it doen't work, giving me the following error message:
Unable to merge flow object stacks: Conflicting FlowObjects: <Loop Context (Head 3:75, Tail unassigned)> - iteration 0 vs. <Loop Context (Head 3:2, Tail unassigned)> - iteration 0 (loops not properly nested?)
In attachment you will find a picture of the workflow
Any help will be really appreciated
Thank you in advance
Massimo
