materialized view in postgresql 9.3

I may ask the question in the wrong place but any way the error message is from mondrian. Recently I downloaded saiku3 community version, my schema file reference to a materialized view in postgresql, but I got the following error message:


mondrian.rolap.RolapSchema$MondrianSchemaException: Table 'kuailian_bi' does not exist in database. (in Table)

In my schema:

<?xml version='1.0'?>
<Schema name="kuailian" metamodelVersion='4.0'>
<PhysicalSchema>
<Table name="kuailian_bi" schema="radius" />
</PhysicalSchema>

The kuailian_bi is the materialized view I created in postgresql.
But I don't get any problem in the saiku version 2.6, can somebody kindly point out a way?
