The "Local Variables" section disappears

I am using Oracle 11g database and SQL Assistant 6.0.70.
Text editor - Notepad ++

The "Local Variables" section disappears after "case...end;" statement.
For example, try to type the following block of code.

	Code:
	1 declare 2 i integer; 3 b integer; 4 begin 5 b := 1; 6 i := case b 7 when 1 then 5 8 else 10 9 end; 10 11 end; 12 /

When we invoke SQL Assistant window (Ctrl+Space) anywhere at the lines 4-8 or at the line 9 before keyword "end;" then the "Local Variables" section is in the list and it shows two variables, i and b. But when we invoke the window after the "end;" keyword (for example, at the line 10) then the "Local Variables" section is not in the list (if we commented the line 9 then the "Local Variables" section will be shown again).

It seems that SQL Assistant treats the "end;" keyword as the end of PL/SQL block and not the end of the case statement.

The same problem takes place when we use local subprograms in a PL/SQL block.
Please find the example below.

	Code:
	1 declare 2 i integer; 3 b integer; 4 5 function f( p in integer ) 6 return integer 7 is 8 begin 9 return p; 10 end f; 11 12 begin 13 b := 1; 14 15 end; 16 /

When we try to invoke SQL Assistant after line 10 the "Local Variables" section is not displayed.

But on nested PL/SQL blocks everything works fine ...

	Code:
	1 declare 2 i integer; 3 b integer; 4 begin 5 b := 1; 6 begin 7 i := 10; 8 end; 9 10 end; 11 /

Thank you. This looks like a bug to me. I was able to reproduce it locally; I will submit a new bug report.
