Serge Huber created UNOMI-1004:
----------------------------------
Summary: A hover condition with only a target id matches every
hover event
Key: UNOMI-1004
URL: https://issues.apache.org/jira/browse/UNOMI-1004
Project: Apache Unomi
Issue Type: Bug
Affects Versions: unomi-4.0.0
Reporter: Serge Huber
Fix For: unomi-4.0.0
h3. Summary
The hover event condition matches when either the target id or the target path
matches (since UNOMI-828). Since UNOMI-982, a part of a condition whose
parameter is not set counts as "always true".
The two changes together mean that a hover condition with only a target id, or
only a target path, matches every hover event. A segment or rule that uses it
then applies to everyone.
The goal of this ticket is that the condition only checks the parameters that
are set.
h3. Ways to explore
* Leave out the parts of an "or" whose parameter is not set. If no parameter is
set at all, the condition must match nothing, or be refused when it is saved.
It must not match everything.
* Look for other built-in conditions that combine optional parameters with "or".
h3. How to test
Create hover events on two different targets. A condition with only the target
id of the first one must match only the first event. Check both the in-memory
evaluation and the Elasticsearch / OpenSearch queries.
