Oracle BLOB value to a LC variable

Hello,

Is it possible in LC ES2 to coerce oracle blob value to some livecycle variable ?

When mapping sql query result (column of type BLOB) to a LC variable (of type Document), we receive:

com.adobe.workflow.datatype.InvalidCoercionException: Cannot coerce object: oracle.sql.BLOB@27e7d6 of type: oracle.sql.BLOB to type: com.adobe.idp.Document

We have tried mapping to string, binary, Document (, we even desperately hardcoded sql.oracle.BLOB to process XML), but none of this works.

Is it possible to solve this other way, then following ?

Thanks.
