Issue with DB Transaction Start and End in a Loop

Hi KNIMErs,

I used the search function of the forum and found some usefull hints. But in my case nothing will fix my problem.

I want to load a lot of data in a SQlite database to do analytics on thte data.

For this front loading process I built this Workflow.

As you can see the Loop End Node crashes with the descriprion “Loop start and end nodes are not in the same workflow”, really?

If I start the DB Connection before the loop is starting I will get another error in my Metanode.

The error message: “Unable to merge flow object stacks: Conflicting FlowObjects: Try-Catch Context vs. <Loop Context (Head 3:23, Tail unassigned)> - iteration 0 (loops/scopes not properly nested?)”

Has anyone an idea what’s going wrong?
