The PD GetPhysicalOptionValue method returns empty string

[vbazant]

Using PD version 15.2 and DBMS Oracle 10g I have modelled a table with the physical option as follows:
tablespace ADS_DATA_5M
partition by list
(SRC_SYS_ID)
(
partition
P_FIP0
values ('FIP0'),
partition
P_CMD02
values ('CMD02')
)


The obj.GetPhysicalOptionValue("<table_partitioning_clauses>/partition by list/<column_list>/<column>:1") method returns empty string for that table. The obj.HasPhysicalOption() method with the same parameter returns False.

Any suggestions?
Thanks
