I am unable to use a recursive loop to get input from user.
The aim of the workflow is to get 3 inputs with the possibility to reset one of them. 1 entry is fixed after the 1st iteration, the 2nd can change, the 3rd one is reset at each iteration. The user exits the loop by selecting the option ‘Fin’ in the web portal.
I run into several issues:
1/ I cannot exit the loop after the first iteration. Knime is expecting a value greater then 0.
2/ When I run the workflow in Knime analytics and select the option to exit the loop, I’m getting an error I do not understand: ‘Recursive Loop End : 0:47 : Caught “IllegalStateException”: No file store handler set on node’. This is a problem to develop the rest of my workflow.
The workflow works perfectly on the Knime server when I execute at least 2 loop iterations.
I have enclose the workflow if somebody could look into it and help me to solve the issues that would be great.
