[#3114] - Problem on mondrian

I am also Facing one Problem

The demo.xml is
<?xml version="1.0"?>
<Schema name="SudeepSchema">

<Cube name="DivyaCubeReal">
<Table name="StateWiseZone"/>

<Dimension name="State">
<Hierarchy hasAll="true" allMemberName="All State">
<Level name="State" column="state" uniqueMembers="true"/>
</Hierarchy>
</Dimension>
<Dimension name="Zone">
<Hierarchy hasAll="true" allMemberName="All Zone">
<Level name="Zone" column="zone" uniqueMembers="true"/>
</Hierarchy>
</Dimension>
<Dimension name="type">
<Hierarchy hasAll="true" allMemberName="All Type">
<Level name="Type" column="type" uniqueMembers="true"/>
</Hierarchy>
</Dimension>

<Measure name="Total Count" column="type" aggregator="count" formatString="Standard"/>
</Cube>
</Schema>

and the Query is SELECT {
([type])
} ON COLUMNS,
{
([Zone].[All Zone],[State].[All State])
} ON ROWS
FROM [DivyaCubeReal]

The Report gets generated ,but When I expand All State colum I am getting this error below :

Caused by: com.tonbeller.jpivot.olap.model.OlapException: mondrian.olap.MondrianException: Mondrian Error:Internal error: Error while executing query [select {[type].[All Type]} ON COLUMNS,

Any idea why this error is coming. I feel that the mdx query is not getting executed and I am missing some join or connection b/w 2 tables.
