Hi Oleksandr,
... but do you really need test it to resource name what you (or other
user/admin/...) can easily change also over GUI in some refactoring?
We prefer comparing over resource OID what is static, an example from my
one config used in simpleResourceObjectNotifier:
<expressionFilter>
<script>
<code>
import
com.evolveum.midpoint.notifications.api.events.ResourceObjectEvent
import
com.evolveum.midpoint.xml.ns._public.common.common_3.ShadowKindType
(event instanceof ResourceObjectEvent
&& *event.getResourceOid() ==
'feed0000-0000-0000-0004-000000000002'*
&& event.isAdd()
&& event.isShadowKind(ShadowKindType.ACCOUNT))
</code>
</script>
</expressionFilter>
Best regards,
Gustav
