Possible bug or strange behavior: Recursion in DocumentService.GetFileDeleteRestrictionsByMasterId

Hello again 🙂

also described in the Recycle Bin idea threat, when I want to check of other Restrictions in the DocumentService.DeleteFileEvents Event I programmed myself, it wents into a recursion. Below a excerpt from my code without the fix.

If you don´t remove the event, it will call itself again and again.

using Autodesk.Connectivity.Extensibility.Framework; using Autodesk.Connectivity.WebServices; using System; using System.Collections.Generic; using System.Linq; namespace MyVaultExtensions { public class MyVaultRestrictions : IWebServiceExtension { public void OnLoad() { DocumentService.DeleteFileEvents.GetRestrictions += new EventHandler<DeleteFileCommandEventArgs>(DeleteFileEvents_GetRestrictions); } private void DeleteFileEvents_GetRestrictions(object sender, DeleteFileCommandEventArgs e) { var ds = (DocumentService)sender; // Check if Vault or other restrictions are found for the file, if so, don´t do anything var res = documentService.GetFileDeleteRestrictionsByMasterId(eventArgs.FileMasterIds.FirstOrDefault(), eventArgs.FolderId); // here he runs forever now /* the rest of your code will never be executed */ } } }

The fix is to remove the Event for the time of the check

private void DeleteFileEvents_GetRestrictions(object sender, DeleteFileCommandEventArgs e) { var ds = (DocumentService)sender; // Check if Vault or other restrictions are found for the file, if so, don´t do anything var res = documentService.GetFileDeleteRestrictionsByMasterId(eventArgs.FileMasterIds.FirstOrDefault(), eventArgs.FolderId); // here he runs forever now /* the rest of your code will never be executed */ }

I would rather not have to do such hacks, but I trust Vault that the restrictions from i.e. LifeCycles are working and my code should not run.

Any other suggestions?

Best regards

Thomas
