Make it possible to search for missing annotations
|Reported by:||Nicklas Nordborg||Owned by:||Nicklas Nordborg|
There is an issue that manifests itself when filtering lists of items based on annotation values. It is easy to search for specific annotation values. But if you enter a filter expression,
<>, an error message is displayed:
InvalidUseOfNullException: Invalid use of null. The 'value' value cannot be set to null.
The reason for this is that the current query API doesn't allow null values when searching for annotations simply because null values are not allowed as annotation values. In the case of filtering, searching for null should find items that has not been annotated with the specified annotation type.
