Hi! I am trying to run the 01_Stocks demo workflow, and I consistently get “NullPointerException” errors. This was after resetting KNIME with -clean parameter from the command line.
Cheers,
Fernando

Hi @peleitor -
I wasn’t able to reproduce the problem here (although I only ran the first 5 stocks or so to take a quick look).
One thing to check - did you download the complete workflow group 58_Stock-Modeling from the EXAMPLES server? If not, that might be why your Call Local Workflow node is failing, since this parent workflow invokes a child workflow.
If originally you got the single 01_Stocks workflow from the Hub, the complete group is available here: https://api.hub.knime.com/repository//Users/knime/Examples/50_Applications/58_Stock-Modeling:data
Does that help?
Hi! Thanks for your reply. I answered by email but I see it did not get posted here.
Actually, I´ve already dowloaded both workflows from Example Server, and at that point it was not working.
I downloaded again, this time from Hub, and it is working. I can´t explain why…
Regards,
Fernando
