Bug

Work Environment

TheHive version 2.13.x

Problem Description

Even if MISP connector is not enabled, the share button is available on the case detail page. If one clicks on it, the browser console shows:

TypeError: Cannot read property 'servers' of undefined
    at Object.<anonymous> (CaseExportDialogCtrl.js:11)
    at Object.invoke (angular.js:4718)
    at $controllerInit (angular.js:10354)
    at resolveSuccess (ui-bootstrap-tpls.js:4552)
    at processQueue (angular.js:16383)
    at angular.js:16399
    at Scope.$eval (angular.js:17682)
    at Scope.$digest (angular.js:17495)
    at Scope.$apply (angular.js:17790)
    at done (angular.js:11831)

Steps to Reproduce

1. disable MISP connector
2. go to case detail
3. click on share

Possible Solutions

Hide the share button or better, tell to the user that MISP connector is disabled when he clicks on share.

The second solution is better because the sharing count indicator is shown. The case can be shared and then MISP connector disabled.
