From Marian:

There are some issues when trying to pass a temp-table as parameter if it contains at least one P.L.O field in it. The ASM class loader used for each instance can't find the object class.

The getter/setter for the field in table definition looks ok (object), however while assigning a value to the field does use the setter method when I want to access the field value it goes through the FieldReference.getValue method which returns a BaseDataType so it fails to compile. Maybe the P.L.O support in temp-tables is not yet complete.

The stack trace below, tried to isolate that in a simple test - table/parameter/test_plo.p.
