We're on OBIEE 11g, 11.1.1.9.0 on Linux RedHat 64bit.  For one specific table, users are receiving "Failed to Load(Invalid JSON payload" when trying to specify or search for values in a column filter (or prompt that uses the filter) in an analysis.  Only specific columns seem to be affected (FULL_NAME, LAST_NAME, FIRST_NAME, MI, MIDDLE_NAME) all of which are type varchar2 in the backend database.  Has anyone else seen this issue, and, if so, what did you do to resolve it?
