Error when updating Wiki: Entity may not be null #354

Open kuruhuru opened 4 years ago

kuruhuru commented 4 years ago

I created a simple test that leads to an error on Redmine 4.1.0.stable

    public static void main(String[] args) {
        RedmineManager manager = RedmineManagerFactory.createWithApiKey("XXX",
                "XXX");
        Transport transport = manager.getTransport();
        ProjectManager projectManager = manager.getProjectManager();
        try {
            Project project = projectManager.getProjectByKey("secs-building-example-project");
            WikiPageDetail wdetail = manager.getWikiManager().getWikiPageDetailByProjectAndTitle(
                    "secs-building-example-project", "Wiki");
            wdetail.setText(wdetail.getText() + "\nCHANGED!!!");
            wdetail.update();
        } catch (RedmineException) {
            e.printStackTrace();
        }
    }

I've created a PR: https://github.com/taskadapter/redmine-java-api/pull/355 I don't know how to run the test. But I got it works with Gerrit its-redmine plugin with Redmine 4.1.1. Please have a try.
