Set and remove multiple permissions on a page

[Sabrina F.]

Hi there!

I am trying to remove and add permissions (page restrictions) in bulk on Confluence Pages using Scriptrunner. I am looping through my ids which I'm getting from a resultset of a database query.

When iterating through I get this error after the permissions of the first entry are set and removed correctly:

2022-04-27 08:18:12,662 ERROR [common.UserScriptEndpoint]: Script console script failed:

java.util.ConcurrentModificationException at org.hibernate.collection.internal.AbstractPersistentCollection$IteratorProxy.next(AbstractPersistentCollection.java:864) at testLoop.run(testLoop.groovy:50)

this is my script:

def userAccessor = ComponentLocator.getComponent(UserAccessor)

def contentPermissionManager = ComponentLocator.getComponent(ContentPermissionManager)

String[] PageIds = ["31920133", "126354667"] 

String groupToRemove = "group"

def pageManager = ComponentLocator.getComponent(PageManager)

def pages

def List<Page> pagesPageList = []

pages = PageIds.each{ pagesToEdit ->

    if (!pagesToEdit) {

        log.warn("Page: " + pagesToEdit + " was not found in the System.")

    }

    pagesPageList.add(pageManager.getPage(pagesToEdit.toLong()))

}

def group = userAccessor.getGroup(groupToRemove)

if (!group) {

    log.warn("Group: " + groupToRemove + " was not found in the System.")

}

String[] groupsToAdd = ["se", "ssa-test"]

def editPermissions = []

    groupsToAdd.each{ groupToAdd ->

    editPermissions.add(ContentPermission.createGroupPermission(EDIT_PERMISSION, groupToAdd as String))

}

def mapEdit = [(EDIT_PERMISSION): editPermissions] as Map

//EDIT

for (Page page : pagesPageList) {

    for (ContentPermission cp : page.getContentPermissionSet(ContentPermission.EDIT_PERMISSION)) {

        log.warn(cp.toString())

        if (cp.toString().contains("groupName=" + groupToRemove)) {

            // Remove the Permission

            log.warn("Group: " + groupToRemove + " was found having EDIT Permissions for Page Id: " + page.getContentId() + ".")

            contentPermissionManager.removeContentPermission(cp);

            log.warn("Removed EDIT permissions for Group: " + groupToRemove + " for Page Id: " + page.getTitle() + ".")

            // Set the Permission

            contentPermissionManager.setContentPermissions(mapEdit, page)

            log.info("Added EDIT Permission for Group: " + mapEdit + " for Page Id: " + page.getTitle() + ".")

            }

    }

}

I assume I have to somehow commit the first operation but I don't know how... 

Hope that someone can help me - thank you in advance!!

Best regards
