Samigo - two different published assessments have identical Published Assessment URLs

SavePublishedSettingsListener.java processAction(ActionEvent)

assessmentSettings will have the correct assessmentID, but the wrong alias. Instead it will show the alias for the quiz in the 2nd tab.
can we lookup the alias and check if any existing alias' assignmentID (i.e. the 2nd tab's id) matches with the submitted assessmentId?

but are there other settings that are mismatched? do we check them all?

then in SavePublishedSettingsListener.java setPublishedSettings(...), the bad alias is saved to the assessment

again, is any other meta data being set to the wrong assessment's metadata?

but it would be best if the context didn't have the wrong / mis-matched metadata to begin with. or... further up the chain, could it detect that multiple tabas are open and not even continue saving?

I found a way to reproduce this (without manually editing the database) and it involves editing two samigo tests simultaneously with two browser tabs open

see the test plan above

Also after causing the duplicate aliases, if you visit the published url, that will cause a null pointer exeption (see also SAK-45764 , which i closed as a duplicate of this)

another possible bug as result of having duplicate ALIASes is that the ckediltor's link feature which pops up elfinder, which elfinder then will not display the duplicate alias url

this sounds like or is a duplicate of SAK-43742, but does the fix in that issue

https://github.com/sakaiproject/sakai/commit/55898a3eb914aae904161729676bb27afb3654c0

merely prevent the bad link from lessons? Does it prevent the duplicate ALIAS from getting in there in the first place?
