Bug: Projects disappear from tree viewer

[bpindelski]

See ​https://www.openmicroscopy.org/community/viewtopic.php?f=4&t=7452.

Another scenario:

• follow user and group creation as in the forum thread,
• log in as "baggins", import an image to a P/D structure (e.g. Project A/Experiment 01),
• log in as "gamgee", import an image to a P/D structure (e.g. Project B/Experiment 02),
• log in as "baggins" - no projects visible anymore.

Restarting insight should bring back the Project A folder back to view.

Dominik could you have a look at that one while i am away?

[dlindner]

Seems to be a problem of user switching, independent of creating projects/importing files.
Switch to another user once works fine, doing it twice fails.

[jburel]

Something is probably not clear preventing the data to be reloaded.

[rkferguson]

Switching user seems to be causing a number of problems - I am scoping default-owner rendering settings and getting weird things happening as well. Have to quit Insight and restart and log in again.

[jburel]

Gus: could you do a review and list the problems. Add them to this ticket, we can them break items into tickets. Thanks

[wmoore]

One I remember is that the owner of some images applies their rendering settings and saves, then switch user and view the same images - they appear to have the owner's settings still. But if you quit and log in as that user you won't see the owner's settings on those images.

[rkferguson]

Will do thorough review as there seem to be some permissions confusions with what I was doing.

Ok, I'm stuck with this... traced it down till OMEROGateway.loadContainerHierarchy(SecurityContext? ctx, Class rootType, List rootIDs, Parameters options) (line 2217)

The weird thing is, that this method called with exact the same parameters returns different results.
Scenario:
1) Logged in first time with user "baggins": Method returns Project A, as expected
2) Switched to user "took": Method return Project C, as expected
3) Switched back to user "baggins": Method returns an empty set, though it was called with exact the same parameters as in step 1!

What server are you running against? Can you capture the Blitz-log.0 for the period of your test? Especially the lines matching "Meth:", "Rslt:", and "Auth:"

[dlindner]

I use the local server (which is build from the build.py script under ./dist)

Snippet from Blitz.log: (While posting this I just noticed, that it's not the same parameters, it's the wrong user in Auth in the third call, that's a lead...)

The user= values in the Auth lines are suggestive: presumably we expect them to vary as the logged in user.
