[ https://issues.jboss.org/browse/JBIDE-21674?page=com.atlassian.jira.plugi... ] Viacheslav Kabanovich commented on JBIDE-21674: ----------------------------------------------- The user choice Flat/Hierarchical is persisted so that if Eclipse closed/opened or even Project Explorer is closed/opened, the last user choice is applied. Not interfering with the user choice leaves an opportunity for setting hierarchical view only _once_ for the entire life of the workspace. Then the fact should be stored as a root persistent property, and never be done again. Hierarchical view is implemented with NestedProjectsContentProvider which is registered as a navigatorContent with attribute activeByDefault="false" which makes it possible to activate only in a programmatic way by invoking command org.eclipse.ui.navigator.resources.nested.changeProjectPresentation . The easiest way to have hierarchical view by default enabled is to convince developers of Project Explorer to set activeByDefault="true". Otherwise, we can do it with a part listener, and if we want it for this release, we can do it now. -- This message was sent by Atlassian JIRA (v6.4.11#64026)
