Double click on a folder in browsed workspace for resource creation causes NPE ------------------------------------------------------------------------------ Key: JBIDE-22437 URL: https://issues.jboss.org/browse/JBIDE-22437 Project: Tools (JBoss Tools) Issue Type: Bug Components: openshift Affects Versions: 4.4.0.Alpha2 Reporter: Marián Labuda Assignee: Dmitry Bocharov Labels: openshift_v3 Fix For: 4.4.0.Alpha3 When I double click on a folder which is empty in Select OpenShift resource shell, which is opened by click on Browse Workspace button in New OpenShift resource wizard, NPE is thrown. If I click on arrow next to a folder, arrow disappear, because there are no files in the folder, but double click, which is supposed to expand a folder throws NPE with following stack trace: {code}
