[richfaces-issues] [JBoss JIRA] Resolved: (RF-10987) Improve GraphValidator performance

Improve GraphValidator performance ---------------------------------- Key: RF-10987 URL: https://issues.jboss.org/browse/RF-10987 Project: RichFaces Issue Type: Bug Security Level: Public(Everyone can see) Components: component-validators, optimization Affects Versions: 4.0.0.Final Reporter: Alexander Smirnov Assignee: Alexander Smirnov Priority: Critical Labels: tran Fix For: 4.1.0.Milestone1 Original Estimate: 0 minutes Remaining Estimate: 0 minutes ClonedObjectResolver became performance bootleneck. We have a very simple page that displays a rich:datatable. We noticed that on the backend ClonedObjectResolver.resolveCloned gets called a lot and is very slow. Looking at the method (code below) I think the issue is that it scans the request map every time and looks for a graph prefix validator. If we comment this code out the performance improves 50%. The main question is what is it trying to do and is this only needed in some specific situations like a particular component on the page? {code} public static Object resolveCloned(ELContext context, Object base, Object property){ if(null != base || null != property){ FacesContext facesContext = FacesContext.getCurrentInstance(); Map<String, Object> requestMap = facesContext.getExternalContext().getRequestMap(); for (String key : requestMap.keySet()) { if(null != key && key.startsWith(UIGraphValidator.STATE_ATTRIBUTE_PREFIX)){ UIGraphValidator.GraphValidatorState state = (GraphValidatorState) requestMap.get(key); if(state.isSame(base, property)){ return state.getCloned(); } } } } return null; } {code}
