Expand Operator generates code errors in OWB 10g2 map

Question

I suspect that there are few people that actually use the Expand Operator in OWB from the lack of threads in this forum; however I'll give this a shot.
I have a map function that returns a user-defined object type which I then use an Expand Operator to break into its component data parts. The function works Ok. The map validates Ok. The code generates Ok. However, on deployment the map generates errors:
ORA-06550: line 768, column 97:
PLS-00103: Encountered the symbol "." when expecting one of the following:
* & = - + < / > at in is mod remainder not rem then
<an exponent (**)> <> or != or ~= >= <= <> and or like LIKE2_
LIKE4_ LIKEC_ between overlaps || multiset year DAY_ member
SUBMULTISET_
The symbol "* was inserted before "." to continue.
Compiling the package body in SQL developer, I can spot the exact lines that produce this error, so I know it's coming from the Expand Operator's generated code. In every case, the Expand Operator is producing lines like this (code generalized):
(("[function_name]"("[map_name]"."[map_input_parameter]"))).BYTES_COUNT
(("[function_name]"("[map_name]"."[map_input_parameter]"))).ROWS_INSERTED
BYTES_COUNT and ROWS_INSERTED are data components of the user_defined object type returned by the function.
The problem is the # of parentheses surrounding the function name and the returning component being outside these parentheses. If I move the returning component in between the first and second closing parentheses, the code will compile:
(("[function_name]"("[map_name]"."[map_input_parameter]"*).BYTES_COUNT))*
(("[function_name]"("[map_name]"."[map_input_parameter]"*).ROWS_INSERTED))*
IMO, this is an OWB bug !! The Expand Operator can't be used without editing the code after deployment.

Answer 1

Unfortunately breaking apart the user-defined type in an Expression Operator produces the same error message and virtually the same code problem:
(([function_name]("[map_name]"."[input_parameter]")).BYTES_COUNT/* EXPRESSION.OUTGRP1.BYTES_COUNT */)
As in the Expand Operator the line above compiles when the data type component ("BYTES_COUNT") is manually moved between the first and second closing parentheses:
(([function_name]("[map_name]"."[input_parameter]").BYTES_COUNT/* EXPRESSION.OUTGRP1.BYTES_COUNT */) )
