JIRA Saved filter using Team field in JQL throws error

[Jayasree SenthilKumar]

1.Creating JIRA filter with team fields gives error

If the filter condition is 

Issuetype=story and team is empty

the search results shows result, but if tried to save this filter and it throws error saying

'Sorry, we had technical problems during your last operation'

The Portfolio team currently does not support searching with "is EMPTY" see JPOSERVER-1723 for details. 

Until this feature gets implemented you can use the following JQL workaround to find orphaned issues:

1. Define a JQL-filter:  "All Teams" = Team in (list of all teams) 
2. use filter != "All Teams" to get all issues without a Team set

I would say it is even worse in my case. I have tried your filter, only adding a project clause (we have multiple projects), so that my filter is:

project = FSORP and Issuetype=story and team is empty

Portfolio search returns 2 stories:

1. One has no Team assigned, so it is expected.
2. The other has a Team assigned, yet it is reported.
3. Importantly I have many more stories with no team specified, yet they are not listed

Is that a bug?
