SQL developer 3.0 - Few Query Builder issues

Question

Hi All,
I have just started using SQL Developer 3.0 so have not fully browsed thru all of the available options in SQL Developer. I have been trying to work on creating and editing sql statements using Worksheet and Query Builder.
I am working on to test this tool so I can give it to the users for them to try and use it - they used to work on the old Query Builder 6.0.7....since it is already de-supported long back to work against 11g database, I am hoping to tell them to use SQL developer 3.0 instead.
Hence, if an user doesn't know how to write a sql statement, he/she would try to do the same using Query Builder.
So, the following questions are more aligned towards a normal user who would try to create a query in the Query Builder window, instead of directly typing a sql statement in the Worksheet window.
1) How to establish/create a relationship between tables after you have dragged down the tables into the Query Builder window? - i tried but couldn't get any options!.
2) Sometimes I see 'Connection closed' error when i try to run a query. How to refresh the connection without opening a new Connection tab?
- I tried this but evertytime it opens up a new connection tab, while the old tab is still present.
3) Columns in the Expression field in Query Builder window can ONLY be displayed in the result set, if the 'output' box on the extreme left of the 2nd section in Query Builder window is checked.
Now when i try to check the output box for an expression (with few aggregate functions), the 'Grouping' check box automatically gets checked, which when run throws an ORA-00934 error: group function is not allowed here...but when I de-select the 'Grouping' check box, the 'output' box also gets un-checked!.
How to solve this out?
Please let me know the resolutions of the above - much appreciated.
With Regards,
Pamir

Hi,
As Raghu noted above, and you also saw in rp0428's following reply,
Re: Problem with displaying sdo_geometry objects
drilling down to the cell edit details is your only recourse for now. Apparently there will be further work done in this area, but it is not clear exactly what or when it will be. For those with access to it, here is a bug reference:
Bug 13680849 - RC1: NOT DISPLAYING THE DATA OF MDSYS.SDO_GEOMETRY
