[BUG] Metanode link broken when name contains + character

KNIME Analytics Platform
1

When saving a metanode as a template and its name contains a "+" sign, the "Metanode Link Update" fails when re-opening the workflow, obviously because the "+" character is transformed into a space (fwiy, I'm on a Mac).

Thanks for the bug report. I’ve added a ticket to the issue tracking system.

This still happens with recent KNIME.

Hi @qqilihq -

After a bit of digging, I found this bug in Jira (internal tracking: AP-7805). I’ll add another +1 from you in our system, and I’ll get it in front of the dev team too.
