Title: Message Title

Jan Haderka created an issue   Magnolia UI / MGNLUI-3377 Availability check on multi action blocks UI Issue Type: Bug Affects Versions: 5.3.7 Assignee: Unassigned Components: app framework Created: 17/Mar/15 9:37 AM Priority: Neutral Reporter: Jan Haderka Security Level: Public Having none destructive (such that preserves selection) action that can be applied to multiple items will block UI for given user and send CPU on server to 100% usage. To reproduce: select number of items in the workbench execute some non destructive multiaction on them (Create one if you don't have anything ready, it doesn't have to do absolutely anything) after exectution of the action, TreePresenter will collect all selected items and fire SelectionChangedEvent on them in TreePresenter:144 eventBus.fireEvent(new SelectionChangedEvent(Collections.unmodifiableSet(new HashSet<Object>(selectedItemIds)))); this in turn will force evaluation of ALL actions configured in the app on EACH item ... if you have anywhere around 100 items selected, you can go for coffee before availability for all is checked ... you can use your App/DB server cpu to heat up that coffee too code triggered by the action gets stuck in info.magnolia.ui.framework.availability.AvailabilityCheckerImpl.isAvailable(AvailabilityDefinition, List<Object>) while (isAvailable && ruleIterator.hasNext()) { AvailabilityRule rule = ruleIterator.next(); boolean ruleHolds = rule.isAvailable(idsToCheck); isAvailable &= ruleHolds; } Add Comment   This message was sent by Atlassian JIRA (v6.3.15#6346-sha1:dbc023d) ---------------------------------------------------------------- Alternatively, use our forums: http://forum.magnolia-cms.com/ To unsubscribe, E-mail to: <dev-list-unsubscr...@magnolia-cms.com> ----------------------------------------------------------------
