[jbosstools-issues] [JBoss JIRA] (JBDS-3798) Repeated component detection keeps stale values

[Jan Richter (JIRA)]

     [ https://issues.jboss.org/browse/JBDS-3798?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Jan Richter updated JBDS-3798:
------------------------------
    Description: 
Installer detects existing tools on confirmation page. If after that a change happens (like the user uninstalls VirtualBox) and then the user goes to the previous page and to confirm page again - the change is correctly detected, but instead of replacing the old option, there are now both options for 'install' and 'use existing'. Plus the count of detected components stays the same.

Using the existing (no longer existing in fact) installation fails, naturally.
