Fix execution flow

Opened this issue · 0 comments

I tried to execute some algorithms (SCDP, BinderFile) with a CSV file with a size of 1.7GB. The execution started properly, but I got some weird behaviour while executing. After some seconds the algorithm appear in the History List with an execution time of 0s and running, but when clicking on the algorithm I get no results and a "Execution aborted" message. In the terminal I get a NullPointerException when accessing the Results, nothing else.
We should rethink the flow for algorithm executions. Right now, there is no indication for the execution status for long executions. Additionally the stop button is not working for me.
