Optimize SiteMap portlet by setting a filter on the node tree instead of using PageNavigationUtils.filter --------------------------------------------------------------------------------------------------------- Key: GTNPORTAL-1284 URL: https://jira.jboss.org/browse/GTNPORTAL-1284 Project: GateIn Portal Issue Type: Task Security Level: Public(Everyone can see) Reporter: Minh Hoang TO Assignee: Minh Hoang TO Original Estimate: 6 hours Remaining Estimate: 6 hours In current code of SiteMap portlet, whenever there is a call to reload the tree (on expand/collapse the node), the filter method in PageNavigationsUtils is implicitely invoked. That results in two drawbacks: 1. A traverse over navigation trees is required, whereas on rendering , tree traversing is mandatory ( see the UISitemap.gtmpl ) 2. Multiple data cloning It is better to define a filter in the UISitemap 's tree object and remove the invocation to PageNavigationUtils.filter ( analogous ideas could be found in UIFilterableTree, see GTNPORTAL-1139)
