[jonenst]

• Do you want to request a feature or report a bug?
  A bug

• What is the current behavior?
  In the following circumstances, the filters of the security analysis results are not saved.

• If the current behavior is a bug, please provide the steps to reproduce and if possible a minimal demo of the problem
  Prepare 2 projects with security analyses, where one project has precontingency and the other postcontingency violations. Change the default filter on both projects to show the contingency. Close the GSE and reopen it. Only the filter of the project selected during shutdown is saved, the other is reset.

• What is the expected behavior?
  Both filters should be saved.

• Please tell us about your environment:

  • PowSyBl Version: 2.5
  • OS Version: linux

The filters are stored using the java.util.Preferences API (note: on unix in $HOME/.java/.userPrefs/com/powsybl/gse/security/prefs.xml )

When calling dispose on the SecurityAnalysisViewer, we get the prefs to save but CheckListView getCheckModel().getCheckedIndices() gives an empty list.. Not sure if it's because it's tabbed out or because of the HideSidesPane or something else..
