The upgrade from version 7.0.21 to version 7.0.22 has changed the logic of evaluating dependent items.
A dependent item (LEVEL2) that has a dependency on a previous dependent item (LEVEL1) evaluates to "Custom on fail" even if there was no change in value at level 1.
Example:
- We have a master item, for example for a log for various events
- There are several dependent items "level1" linked to the master, each evaluating its own search string and has a preprocessing where there is a custom on fail: Discard value (the first picture)
- There are several dependent items "level2" linked to "their" item "level1" and have a preprocessing where there is a custom on fail: Set value to: -999 (the second picture)
Since version 7.0.22, a dependent item is evaluated even if its master did not change the value.
Result:
7.0.23:
Expected:
Like it was in 7.0.21:
