Summary:¶

If "Workspace Management" is enabled the backend will try to display the workspace titles in the workspace menu.
There seems to be "fallback" code to switch to the "live" workspace if the currently selected workspace does not exist.
However, if the "Edit live" flag is cleared for this user, there ist no live workspace for this user that would be selectable.

=> This causes an exception when the backend tries to display the workspace title in the workspace selection box.
=> This happens not only if there is no more workspace that the user is assigned to, but also if there is another workspace (with the user assigned as "Member").
It seems there is only a fallback to -99 (live workspace).

Steps to reproduce the problem:¶

(note 1)

• Create non-admin test-user
  - In Tab "Mounts and Workspaces" UNCHECK "Edit live (online)"

• Login to BE using this user (it helps to have 2 different browers, one for admin access, one for test-user access) => everything should be ok

• Enable extension "Workspace Management" (note 4)

• Refresh test-user browser (note 2)

• Create workspace
  - Assign user to "Members" list within workspace
  - Look at database table "be_user", field "workspace_id" => should now be the id of previously created workspace

• Refresh test-user browser (note 2)

• Now remove the workspace

  - Look at database table "be_user", field "workspace_id" => should still be set to the previously assigned workspace id

• Refresh test-user browser => this will show an exception (see below)

  - Look at database table "be_user", field "workspace_id" => should now be set to -99 (= live workspace)
  From this point it is no longer possible to use the BE as this user (note 3). Even restarting the browser will not help.

(note 1) This was a fresh install of TYPO3 8.7.0, no upgrade.
(note 2) When I first tried creating a workspace and assigning a user, the problem occured even without having removed any workspace! Could this be related to the order of actions (created user first, and enabled extension afterwards -- possibly "workspace_id" set to -99 initially, but if "Edit live" is deselected (= db field "workspace_perms" = 0) this entry would be invalid?]
(note 3) Assigning "Admin" flag to the user or deactivating the "Workspace Management" extension will allow the user to work/login again [because this gives access to live editing], but will not fix the problem permanently.

Workaround to fix the problem from the backend UI:¶

Either:

• Create a new workspace
• Assign test-user to "Owners" of this workspace (note 5)
  - Look at database table "be_user", field "workspace_id" => should still be set to -99
• Refresh test-user browser => backend works again (note 6)
  - Look at database table "be_user", field "workspace_id" => now set to the new workspace id (inconsistency is fixed)
• Assign test-user to "Members" of this workspace

or:

• Edit the user and CHECK the "Edit live" flag
• Refresh test-user browser => backend works again (even without any workspace)
• Select a workspace (note 7)
• Turn off "Edit live" again

(note 4) This problem will only appear if "Edit live" is UNCHECKED (= db field "workspace_perms" = 0)
(note 5 and 6) These are the important steps: assigning the user to "Members" will not fix the problem, it is necessary to assign the user to "Owners" temporarily and then accessing the backend once.
(note 7) Without manual selection of another workspace the problem re-appears when turning "Edit live" off again
