Check_MK Werk 5521: logwatch: Fix exception in WATO's check parameter display

ID: 5521 Title: logwatch: Fix exception in WATO's check parameter display Component: Checks & agents Level: 1 Class: Bug fix Version: 1.5.0i2 Previously, WATO's check parameter display would complain about invalid check parameters, due to logwatch's parameter precompilation working well with the check itself, but breaking the GUI's validation. This was a purely cosmetic issue.
