Central projects Wizard sometimes fails to open ----------------------------------------------- Key: JBDS-4735 URL: https://issues.jboss.org/browse/JBDS-4735 Project: Red Hat CodeReady Studio (devstudio) Issue Type: Bug Components: central Affects Versions: 12.9.0.GA Environment: manually Fedora 28, manually Fedora 29, manually RHEL 7.7, automation Reporter: Vojtech Prusa Assignee: Jeff MAURY Priority: Major Fix For: 12.14.0.AM1 Attachments: central.tar.gz, image-2018-10-17-09-24-31-555.png, issue-reproduced-19-11-16.png, screenshot-1.png h2. This issue has been successfully reproduced on the following OSes: * Fedora 28 * Fedora 29, JDK 8 * RHEL 7.7, JDK 8 h2. This issue is not reproducible on the following OSes: * OS X, JDK 11 * Windows 10, JDK 8 h2. Details describing this issue: There is "openInIDE" used in 3 places in "main.min.js" in central source code*. When the central reloads and works normally, "openInIDE" is a function (probably defined in Java code or somewhere out of the "main.min.js" file) with following implementation: function openInIDE() { var result = callJava(1, '9aee3b4a3f3b40ed26f47d66375b25e3', Array.prototype.slice.call(arguments)); if (typeof result == 'string' && result.indexOf('org.eclipse.swt.browser.error') == 0) { var error = new Error(result.substring(29)); throw error; } return result; } After the issue appears, "typedef openInIDE" is undefined, which causes probably the issues. *Additional information to the 3 places, where "openInIDE" appears - it appears in 2 functions: - registerButtonClicks() - here is the "openInIDE" needed for loading and displaying the central correctly - delegateToIDE(a, b) - here is the "openInIDE" needed for opening the wizard to the quickstart OLDER DESCRIPTION (does not describes the issue enough, but I decided to keep it for more details about the issue): ---------------------------------------------------------------------------------------------------------------------- Sometimes central examples wizards fail to load and modal dialog is shown instead (screen attached). Nothing in Error log view. Restarting devstudio solves the issue. Adding screen and central tar of: devstudio-12.9.0.GA-v20180928-1629-B3448/workspaces/workspace/.metadata/.plugins/org.jboss.tools.central/central Addition info: Considering that central itests fails for this sometimes fresh installation without restart may cause this. Although it happen again after running devstudio for some time and restarting Central view.
