Checkmk Werk 15001: Fix possibility that changes made by form dialogs were not persisted

ID: 15001 Title: Fix possibility that changes made by form dialogs were not persisted Component: Setup Level: 1 Class: Bug fix Version: 2.2.0i1 If a user saved a form dialog, it was possible, that this change was not applied correctly. This situation could happen if a user had to many browser tabs open or spent a lot of time for one configuration step on a page before saving. Background: The maximal number of transaction IDs for a user was limited to 20 before this werk. Also, the sidebar snapins "Site status", "Master control" and "Bookmarks" used a new transaction ID on each reload of the sidebar. The number of IDs per user is now increased to 30 and the mentioned sidebar snapins no longer use transaction IDs.
