Grep - Extract and regexp group = "null"

Nicolas | Last updated: Oct 05, 2019 01:54PM UTC

Hello, when editing Grep - Extract entries, the regexp group is set to "null" after edition. How to reproduce: - create a new Intrduer attack, go to Options > Match & Replace - click Add then "Extract from regexp group" - enter "a(.*)b" (w/o quotes) and click OK - select this entry and click Edit - uncheck "Case sensitive" and click OK - the regexp group is now set to "null" Tested on Pro v2.1.04

Hi Nicolas, Thank you for your message. I have repeated the steps that you have listed and am seeing the same issue. I will pass this on to the developers for investigation.

Hi Nicolas, This issue is still in our development backlog. We will update this thread when we have some further information.

A small update after three months: I just tested v2.1.07, which is still not fixed :-(
