Hi Mick,
I tried this on a test system and could not reproduce the issue.
Selecting the existing text in the data flow property and typing in a new value then either:
- pressing Enter and clicking on th Re-Run button
- only clicking on th Re-Run button
- using <Ctrl>+<Shift>+R
all resulted in the blue spinner icon being displayed in the Data Flow Title bar (indicating the data flow change was being stored) and then the green play icon being displayed (indicating the data flow was running). In all cases the updated value of the Data Flow property was used by the Filter node.
The tests were performed on v.3.6.3 - what version are you using?
Regards,
Adrian
