many thanks for your reply and the workflow and most of all the work you put into it. I actually did not expect a solution so close to what I needed. Really great!
Just to recapitulate on what I tried before your suggestion:
I used two Widgets but outside the loop.
The first Widget allowed to define the nr of columns (assays) needed:
That integer flow variable was passed to the “Counting Loop Start” Node to define the nr of loops and append the columns respectively:
I then used the Table Editor to allow the modification of the template columns by the user:
I was not that satisfied with my solution so I am very happy for the workflow you provided using a component within the loop.
As I do not have access to the Webserver yet, I tried to replace the configuration nodes in your component with the “respective” Widget nodes and tried to change the column values each step using the Step Loop Execution but that did not work.
Would actually be nice to have the option in the configuration of the loop nodes to let the Interactive Views of Widgets pop up automatically each iteration (there might be a good reason that this is not possible).
I still do not really understand the difference between the Configuration and Widget nodes (need to re-read the manual). Some configuration settings like for the “String Configuration” node and the “String Widget” node look quiet the same so I was wondering if you could just have one of these nodes with both properties (e.g. being displayed in the configuration of the a component and the webserver plus the option for interactive View).
Again bruno29a many thanks, your workflow is a great solution and I will work with that and try to implement your suggestion on the “adding more columns” option during the loop
All the best
