I was able to get the user filter to work and you are correct – the task is performing much better now and hasn’t crashed midpoint yet. Thank you, Pavol!
For the record, here is the complete <activity> section of the iterative task:

I was not able to get the user filter to work. Tips or an example would be much appreciated!
Also, I was running this in an iterative task. This latest crash happen after only 3 minutes, but I asked the UI to do something and that caused it to crash.

Hello Paul,
actually I wanted to write you about this, but I didn't want to bother you with details. :)
You need two filters here:
1. one to select the users with relevant assignments to be deleted
2. second to select relevant assignments from each user found
The first filter is more or less the one you originally wrote (except for equals vs ref issue).
The second one is OK in your update.
Two more comments:
1. In modern midPoint versions the filters could be written using midPoint query language (aka Axiom).
2. The bulk action is best to be run within iterative scripting task; that would prevent heap space problems even if unoptimized (second-query-only) action would be written.
Hope this helps. :)

Is there anyway to place limits on the bulk action task below?
It crashes midpoint completely within about an hour, forcing a hard reboot (version 4.7.1).
This was the error:
Couldn't execute script: com.evolveum.midpoint.util.exception.ScriptExecutionException: Couldn't execute action 'unassign' on POV:user:1fb687f6-028e-4758-a877-3a6b932b1097(someone at somedomain.com<mailto:someone at somedomain.com>): Java heap space

Thanks, Pavol!
For the benefit of the list, here is the bulk action script which will remove all OrgType assignments from all users:
<s:search xmlns:s=http://midpoint.evolveum.com/xml/ns/public/model/scripting-3
xmlns:q=http://prism.evolveum.com/xml/ns/public/query-3>
<s:type>UserType</s:type>
<s:unassign>
<s:filter>
<q:ref>
<q:path>targetRef</q:path>
<q:value type="OrgType"/>
</q:ref>
</s:filter>
</s:unassign>
</s:search>

Hello Paul,
this is a quirk from the prehistory of midPoint: references are not filtered using q:equal but using q:ref.
Furthermore, you may eliminate custom coding by using "unassign" action that provides a filter for assigments to be removed.
See e.g. https://github.com/Evolveum/midpoint/blob/75e549f2e5ce52ab4b008c18e2e7ba8b2072e151/model/model-intest/src/test/resources/scripting/unassign-captain-from-jack.xml#L18-L26 for an example.
Hope this helps. No guarantees, though. :)

I am trying to remove all user assignments to OrgType objects in a bulk action task but am having trouble.
I think I have the filter correct, but I’m having trouble with the script when it tries to examine the type on a given assignment (to prepare it for deletion).
This is the filter:
<q:filter>
<q:equal>
<q:path>assignment/targetRef</q:path>
<q:value type="OrgType" />
</q:equal>
</q:filter>
And this is the first part of the script that checks the assignment for a user:
UserType user = input as UserType
for (AssignmentType assignment : user.getAssignment()) {
if (aassignment.targetRef.type == 'OrgType') {
The error I am getting is:
class com.evolveum.midpoint.prism.impl.PrismReferenceValueImpl cannot be cast to class com.evolveum.midpoint.prism.PrismPropertyValue (com.evolveum.midpoint.prism.impl.PrismReferenceValueImpl and com.evolveum.midpoint.prism.PrismPropertyValue are in unnamed module of loader org.springframework.boot.loader.LaunchedURLClassLoader @2e0fa5d3)
Thanks in advance for any help!
