tDB2Output - Additional Columns - Parameter from row is null

[ToEckert]

Hello,

i am trying update a DB2 row with a key "OBJECTID" (Integer) and a Column "SHAPE" with the type "ST_POINT". Because Talend doesn't know the Db Type "ST_POINT" i need to use the "Additional Columns" option from tDB2Output. The SQL Query would be "ST_POINT( <double1>, <double2>, <integer>)" to create a point. Every rows has its own double1 and double2 parameter (x and y) so i need to pass a row.SHAPE variable. When i run the job, this variable is null and the value of the db2 Column becomes null. The tLogRows are Logging the values, so they are not null.

The content of row.SHAPE should be something like "ST_POINT (12.1555, 5.21115, 1024)".

This is what a test job looks like:

Am I doing something wrong or is it impossible to use row variables there?
